This isn't too far from where her and her family had been staying, I wonder if they've settled close to a native society?
Now away we must go with those barbarous creatures, with our bodies wounded and bleeding, and our hearts no less than our bodies.
Harsh language for sure. I don't like the choice of describing native peoples as "barbarous creatures", but if I were in her position I don't know if I would be thinking about the implications of my presence on these people's land. I would probably also curse whomever kidnapped and beat me.
I considered Spanish to be a private language.

Winter kept us warm, covering Earth in forgetful snow, feeding A little life with dried tubers.
Eliot says that “winter kept us warm,” “covering the earth in forgetful snow,” showing that people felt at peace during winter. Winter is usually associated with depression and slumber, so people may actually feel at peace when they do not have to see reminders of better days. People probably didn’t have very good memories of winter – there was famine, crucial battles, cold, and suffering – but when spring comes, it instantly uncovers the beauty that the world once had. It makes people remember the good things they experienced in the past, so nostalgia hits. It is much harder to be happy when you have good memories that were taken away than when you had nothing in the first place (like winter). This is how the shift from winter to spring feels for many people, especially when spring is no longer the same as it was before.
Going a little bit ahead, in Ezekiel 37 and Ecclesiastes, we can see how important religion is as a source of spiritual fulfillment. The valley of dry bones in Ezekiel 37 symbolizes the Israelites, who have lost their hope and feel as though they are spiritually and physically dead. This connects to Eliot because he also emphasizes the emptiness of people and their loss of spiritual connection. In Ecclesiastes, religion and God are also emphasized, showing the importance of spiritual fulfillment. Worldly things do not ultimately matter because they are temporary, what matters is spiritual meaning. Eliot also explores the possibility of renewal at the very end with “Shantih,” which means “peace”. If people actually begin to change and act, perhaps spiritual renewal is possible (it is not clear to me yet what exactly Eliot means by this, but it could be something like a higher power or a spiritual truth (like the unattainable holy grail) that people need to find within themselves in order to restore the world and save the Waste Land. In this sense, the Waste Land may not be completely hopeless: there is still the possibility of renewal if people can recover some form of spiritual connection)
Bin gar keine Russin, stamm’ aus Litauen, echt deutsch
This line says in German, "I am not a Russian woman at all, I come from Lithuania, genuinely German." This line shows the modernist desire to keep poetry impersonal while still telling a meaningful story. Translated into German, it tells the story of the shifting borders and national identities in Europe around World War I, but only those familiar with that historical context would fully understand it.
The character Marie may connect to Countess Marie Larisch, who grew up in Bavaria, Germany. In her memoir, she describes being the daughter of Duke Ludwig of Bavaria and the niece of the Empress of Austria. These two identities, which come from different parts of Europe, are reflected in the line "genuinely German," as she must explain her complicated background, especially after World War I. She was Bavarian by birth, connected to Austria by family, and part of a European aristocratic world, so she didn't fit into the modern categories of nationality.
I was frightened. He said, Marie, Marie, hold on tight. And down we went.
I find this reference to Marie Larisch quite interesting as I think it really connects to the ideas of the ideas of impersonality which we discussed in class today. Here, Elliot embodies the real life countess, Marie Larisch, thus separating himself from the poem, in a style quite different from classical poetry. I think that this choice is deliberate, as with many others in the opening of this poem to establish that it is a departure from classical poetry, and a step into modernism. This can also be seen with parallels to other poems such as how Elliot subverts The Canterbury Tales opening by describing april as the cruelest month as opposed to a time of rebirth and new life. Ultimately, I think these deliberate choices lead to an interesting opening to the poem which displays how Elliots writing differs from that of classical poets.
‘Nam Sibyllam quidem Cumis ego ipse oculis meis vidi in ampulla pendere, et cum illi pueri dicerent: Σίβυλλα τί θέλεις; respondebat illa: ἀποθανεῖν θέλω.’
"When the boys said to her: 'Sibly, what do you want?' She answered: 'I want to die.' In relation to My Past, by Countess Marie Louise, the English rendering of The Service for the Burial of the Dead...of the Orthodox Greek Church in London, Sibly's plea for bodily liberation transforms the body into a physical vessel that confines the human soul—the soul being the human's godly half (or fragment of god). Throughout all texts, the soul seems to exist attached to rather than held within the human: lines 25-29 of "The Burial of the Dead" state that, "There is shadow under this red rock/ (Come in under the shadow of this red rock),/ And I will show you something different from either/ Your shadow at morning striding behind you/ Or your shadow at evening rising to meet you..." 'Shadow,' is referred to as a definite object; rather than the product of one's body, 'shadow' is a place for the body to take refuge within.
Further, Tone 2 of the "The Service for the Burial of the Dead..." illustrates a soul departing from its body: "Alas! what strife hath the soul in parting from the body. Alas! what tears, and there is none to pity her; towards angels her helpless eyes are turned in supplication...let us plead with Christ for rest for him who has passed away, and for our souls the great mercy." As the soul is described separate from the body, the female pronoun "her" is attached. She, "turned in supplication," asks for the great mercy (assumed to be entrance to heaven, or a similar plane). The female soul, possibly a symbol of virgin rebirth, awaits return to God, and return to sanctity.
Overall, as suggested in the final lines in the Book of Ezekiel, all texts suggest that the human body is a subaltern vessel, and that the soul is the only kin of God (or the child or product of God).
Frisch weht der Wind Der Heimat zu Mein Irisch Kind, Wo weilest du?
This is a direct quote from the beginning of Wagner's opera, Tristan und Isolde: a sailor's song, singing about the wind blowing fresh towards home and asking an Irish girl where she was lingering. This song is performed at the beginning of the story, before the fateful encounter of Tristan and Isolde, the couple's passionate and consuming love affair. Eliot places the quote right after the memory of the hyacinth garden which follows. It's a scene full of romance and eroticism and, interestingly enough, one which ends not in consummation but in the speaker's utter silence and paralysis ("I knew nothing... the silence"). The Wagner quotation sets up an expectation of grand romantic union that the poem's own scene refuses to deliver. It's the same technique as the "Shakespeherian Rag" moment later; high art quoted directly, then undercut by what actually happens around it. Here the gap isn't ironic so much as devastating: real operatic passion promised, and then only emptiness delivered in its place.
‘Nam Sibyllam quidem Cumis ego ipse oculis meis vidi in ampulla pendere, et cum illi pueri dicerent: Σίβυλλα τί θέλεις; respondebat illa: ἀποθανεῖν θέλω.’
This particular quotation stood out to me because of its implications when read alongside The Service for the Burial of the Dead According to the Use of the Orthodox Greek Church. According to this book, death is a passage from one state of existence into another instead of an absence or destruction of life. To reflect this, the burial service becomes a ritual. However, the Sibyl in Eliot's chosen quote (taken from Petronius’s Satyricon) experiences the complete opposite of this condition of "death." She has lived for an unnaturally long period of time, and she is suffering to the point where she feels trapped by her own existence and wishes to die. Contrary to the assumption that death is what brings suffering, Sibyl's anguish stems from her inability to reach closure or transition into a new state of being. This reflection upon the purpose of death lends insight into Eliot's deliberate choice of this epigraph over a quote from A Heart of Darkness by Joseph Conrad. The passage Eliot wanted to select focused on the antagonist Kurtz's death. It appears that Eliot originally wanted to choose something that encapsulated the final moments of death and the meaning concentrated in them, but eventually pivoted and decided to publish something that was the complete opposite. This sets the tone for the rest of the poem. In The Waste Land, death is not final but more so a suspension between states of existence. This condition of suspension is what distinguishes Eliot's understanding of death from that of an Orthodox burial. The latter encourages movement and resolution, but The Waste Land constantly raises fragments of experiences without allowing them to settle, dragging them along as the poem progresses. By using Sibyl to introduce this idea, Eliot introduces a more disturbing understanding of death. It is a state without ending, or in this case, a world without teh ability to change or begin again.
Now let’s take a moment to reconsider the Ferris wheel introduced at the beginning of this section. Suppose a rider snaps a photograph while stopped twenty feet above ground level. The rider then rotates three-quarters of the way around the circle. What is the rider’s new elevation? To answer questions such as this one, we need to evaluate the sine or cosine functions at angles that are greater than 90 degrees or at a negative angle. Reference angles make it possible to evaluate trigonometric functions for angles outside the first quadrant. They can also be used to find (x,y)
wth? I guess we're not going to cover this original problem??
Looking for a thrill? Then consider a ride on the Singapore Flyer, the world’s tallest Ferris wheel. Located in Singapore, the Ferris wheel soars to a height of 541 feet—a little more than a tenth of a mile! Described as an observation wheel, riders enjoy spectacular views as they travel from the ground to the peak and down again in a repeating pattern. In this section, we will examine this type of revolving motion around a circle. To do so, we need to define the type of circle first, and then place that circle on a coordinate system. Then we can discuss circular motion in terms of the coordinate pairs.
I see part 2 where the photographer snaps a photo at 20 feet and makes a 3/4 rotation, but are we not going to solve this?
Next, we will find the cosine and sine of the reference angle: cos(π6)=32 sin(π6)=12

8:07–9:32 When Dustin Ballard breaks down the three things people should think about when using AI in music, I agree. He discusses whether it is deceptive, whether there is artistic intent, and how it affects musicians. I think these are important because artificial intelligence can be a good creative tool but people should be honest about their use of it and think about if it could take opportunities away from real musicians.
4:02–4:39 I found this part interesting because Ballard explained that the song was created entirely by AI from a text prompt. He also mentioned the strangeness of hearing emotion and pain in the voice of someone who never really existed. This made me think of how artificial intelligence can make something sound really real despite there being no real person behind the music or emotions.
2:16-3:14 I was fascinated to hear Dustin Ballard say that the story about the old blues singer and the song was created entirely by AI. At first I thought the story was true because the music sounded real and emotional. When he told us it was AI, I thought to myself, does knowing how music was made change how we feel about it? I think it does, because I felt differently when I found out that the singer never really existed.

the Age of Receding Pandemics—a transition stage—in which the risk of death from infectious and parasitic diseases declines and risk of death from degenerative diseases increases.
This part shows how the introduction of sanitation and better cleaning policies helped reducing the spread of infectious diseases. The main health concern then shifted to chronic illnesses.
As populations became less susceptible to infectious diseases and less likely to die from them, chronic degenerative diseases such as coronary heart disease and cancer became more prominent.
This section shows how the health issues shift over time. As infectious diseases become less common, things such as cancer may become more popular.

It seems imperative that scholars continue to question what truly characterizes American literature within and beyond national boundaries.
Especially because America itself is such a diverse nation built on ideals, questioning what America even is is more of a valid question than it might appear at first.

American literature is ever-changing. This anthology sets out to help people see that
True, but is this not an early American lit course? Why would we focus on change? Unless we're talking about how the definition changes constantly.
Rather, we offer an unexpected
Who would not expect any of these texts to be included in an anthology about American literature? Certainly not our class, as we've already blown to shreds any preconceived ideas one might have about what American literature is.
To what extent does American literature emerge from a collectively shared identity rather than a set of arbitrary geographical constraints?
Shared identity is probably the single most important aspect of literature.
but it is also the entirety of two continents and wherever their influence spreads.
It seems that for the purpose of this class, we are identifying America as North and South America, along with any American territories, to get as broad a scope as possible.
How can we possibly define American literature without comprehending the fragility, complexity, and pride that accompanies such a term?
No one person or group can define what American literature is, there are simply too many different perspectives to consider.
while also giving students the tools to think critically about what’s happening within the field of American literature in the present.
How does it give us the tools to think critically on current events? Are there sections that include other students dissections of texts (not including those made by our class on hypothes.is), or are we given the tools for critical thinking simply by reading the texts ourselves?
this anthology takes things a step further because it makes connections between important works of American literature and contemporary culture (such as films and other references).
What sets this apart from other scholarly conversations on literature? Don't most scholars recognize things like film, music, and other art to be literary?
This anthology provides specific details and insights into multiple texts from diverse authors that are important representations of American literature.
Diverse how? Diverse ethnically? Religiously? Geographically? Sexually?
moves beyond the voices of old white men talking about even older white men.
As we discussed in class, this is important because of the lack of said voices being taught in primary and secondary schools.
This anthology is unique because it was made by students, for students.
Are there not a lot of these? I'm assuming not. Regardless, it's important that we hear from student voices on what literature should be taught, because the things that made an impact on people our age in recent classes are likely to make an impact on us as well and inspire us to keep learning.
How does the in-depth study of early American literature prompt us rethink representations of American culture today?
It allows us to understand the events that shaped our country and led to the social and political climate that exists today.
What is the difference between American literature and American history?
In class, I think we touched on this already. History is a study of events as they happened, while the study of historical literature studies the author's perspective more heavily.
we questioned the very parameters of what counts as American literature.
We also question ideas like what makes an author American, and I'd say that it runs deeper than asking what "counts" as American literature. It's about how far we can push the boundaries, and if American literature even exists. If Native American literature can't exist because of the many cultures and areas that could be considered Native American, why can American literature exist when we end up running into the same issues?

“I was on the banks of the River Styx. The boat came to row me across, but...instead of Charon, it was Huck and Jim. Only, when Huck pulled back his hood he was an old man...like, ninety years old.”
I found this statement interesting, as the substitution of Huck and Jim as the ferryman instead of Charon shows that even with his brain as misfiring electricity, he still thought of a story he loved, before resorting to religious or taught context. This suggests that comfort and identity aren't based on what we're taught, but what we love and truly appreciate.

Esta pérdida general de heterocromatina estimula la activación de las rutas sensitivas de DNA y RNA citosólicas, que estimulan las señales inmunitarias natas y la “inflamación relacionada con el envejecimiento” (inflammaging.)
La célula tiene sensores de defensa que detectan ADN y ARN en el citoplasma porque pueden interpretarlos como una señal de peligro, similar a lo que ocurre durante algunas infecciones virales. Al activarse estos sensores, se pone en marcha la inmunidad innata y se producen moléculas inflamatorias.
En forma sencilla:
Envejecimiento → ↓ heterocromatina → ADN/ARN anormal en citoplasma → activación de sensores de peligro → respuesta inmunitaria → inflamación crónica
A esa inflamación leve, persistente y asociada al envejecimiento se le llama inflammaging (inflammation + aging).
Por ejemplo, la alimentación con grasa abundante reduce la acetilación de las histonas por su capacidad para inhibir a las enzimas ACLY y ACSS2, que producen acetil-coenzima A (CoA). Las concentraciones de acetil-CoA, en comparación con todos los metabolitos medidos, son en efecto los mejores predictores de los niveles de acetilación de histonas.
ACLY y ACSS2 → producen acetil-CoA → acetilación de histonas → cromatina más abierta → mayor expresión de ciertos genes

Other annotators choose a lateral dig that moves back and forth be-tween the text and the social annotations. They might read a paragraph orsection of the assigned text and then pause to review and respond to anyannotations and leave their own before continuing to the next.
I like to do this so I can read the section and grasp what the author is saying and make my own annotations before reading what everyone else has to say about the section that I just read. This way I can keep my thought more organized and on topic since I'm not going back and forth between sections.
This knowledgecan help you learn about others’ perspectives.
I like getting to read annotations for this reason. I get to see what other people are thinking when they read something and I feel like it helps me to widen my own perspective by understanding someone else's thoughts.

another way to describe a position is as the path taken from the origin—point (0, 0)—to the current point. When you think of position in this way, it becomes a vector, just like velocity, as in Figure 1.4. <picture><source type="image/webp" srcSet="/static/797d06eafb90cdebf68c1301ff876f6c/caff3/01_vectors_5.webp 576w,/static/797d06eafb90cdebf68c1301ff876f6c/0f313/01_vectors_5.webp 1152w,/static/797d06eafb90cdebf68c1301ff876f6c/c86c1/01_vectors_5.webp 2304w" sizes="(min-width: 2304px) 2304px, 100vw"/><img data-gatsby-image-ssr="" data-main-image="" style="object-fit:contain;opacity:0" sizes="(min-width: 2304px) 2304px, 100vw" decoding="async" loading="lazy" src="/static/797d06eafb90cdebf68c1301ff876f6c/694e8/01_vectors_5.png" srcSet="/static/797d06eafb90cdebf68c1301ff876f6c/6c4c7/01_vectors_5.png 576w,/static/797d06eafb90cdebf68c1301ff876f6c/d1c40/01_vectors_5.png 1152w,/static/797d06eafb90cdebf68c1301ff876f6c/694e8/01_vectors_5.png 2304w" alt="Figure 1.4: A computer graphics window with (0, 0) in the top left, showing a position vector and a velocity vector"/></picture>const t="undefined"!=typeof HTMLImageElement&&"loading"in HTMLImageElement.prototype;if(t){const t=document.querySelectorAll("img[data-main-image]");for(let e of t){e.dataset.src&&(e.setAttribute("src",e.dataset.src),e.removeAttribute("data-src")),e.dataset.srcset&&(e.setAttribute("srcset",e.dataset.srcset),e.removeAttribute("data-srcset"));const t=e.parentNode.querySelectorAll("source[data-srcset]");for(let e of t)e.setAttribute("srcset",e.dataset.srcset),e.removeAttribute("data-srcset");e.complete&&(e.style.opacity=1,e.parentNode.parentNode.querySelector("[data-placeholder-image]").style.opacity=0)}} Figure 1.4: A computer graphics window with (0, 0) in the top left, showing a position vector and a velocity vector In Figure 1.4, the vectors are placed on a computer graphics canvas.

Marshall Islands stick chart on display at the Berkeley Art Museum (photo by Jim Heaphy) The stick chart is a navigational tool crafted by the indigenous people of the Marshall Islands, located in the central Pacific Ocean. This ancient tool was made by carefully tying together the midribs of coconut fronds. Shell markings on the chart signify the locations of islands in the region. The layout of the fronds and shells serves as a geographical guide, offering an abstract representation of vectors that capture the ocean swell patterns and their directional flow.

The ramifications of the slavery debates lingered over another gath-ering, nearly forty years later. In 1998, David Eltis and David Rich-ardson launched a database containing almost thirty thousand Atlanticslave trade voyages.16 Each record in the database represented a differentslave ship. Each field in each record supplied information culled fromthe ship’s original manifest — name of the ship and captain, dates of thevoyage, number of slaves on board, place of slave purchase, and landing.The computational power of the database as technology and tool allowedresearchers to calculate new information about slave ship voyages basedon incomplete records.
I like how modern technology was able to make these new findings, but its also sad that these records were maybe so casual that they didn't really need to be excessively tracked and accounted for.
Today, the debate surrounding race and incarceration is vast and complex. In 1910, they story was more straightforward, sometimes even more explicit. Even those who debate the role of systemic racism today have to face the obvious fact: we still see the shadow of the undeniable, institutionalized, strategic racism of the 100 years after the Civil War.
Overall, I really like how they tied in slavery to incarceration, and showed the trends of post slavery/segregation era, to now.

In February 2025, Trump fired ~1,000 NPS employees (and has since hired back only a few of them despite two court orders) and also moved to close visitor centers and other facilities. When asked why the NPS would choose not to share their 2024 visit numbers, former National Park Service Director Jonathan Jarvis told SFGATE:

Divide the total rotation in radians by the elapsed time to find the angular speed: apply ω=θt
What happened to the theta^R notation?
A satellite is rotating around Earth at 0.25 radians per hour at an altitude of 242 km above Earth. If the radius of Earth is 6378 kilometers, find the linear speed of the satellite in kilometers per hour.
This problem doesn't make clear that the satellite is rotating around the central point of the Earth and that RADIUS of the satellite, here, means R_E+h_S. Not to mention, that the Earth is not perfectly spherical, or circular in our 2-D model that doesn't include the picture. This problem is such a leap from the previous question and information that it's a wonder anyone can get it.
Angular speed can be given in radians per second, rotations per minute, or degrees per hour for example.
The directions for solving these problems puts these measurements in radians/unit time.
The present study measured the social networks of 3-year-old children (n = 36; 15 female; 68% White) and found that children in larger social networks demonstrated stronger PT skills, particularly on the more difficult trials on the task. These results indicate the size of children's social networks relates to their PT ability.

design theory
"Design is a social activity." I found this interesting because design is not only about making something look good. Designers work with other people and create things for an audience, so design can have an impact on society.
design
Theory is all about the question why? This stood out to me because designers usually focus on how to make something, but theory makes us think about why we are making it. I think asking why can help us make better design decisions.
But who gets to be represented, and who gets access?
This question made me think about how some people can be left out of design. I think designers should consider different people and make sure their designs are accessible and inclusive.
Creating a more just world requires struggle and debate
This stood out to me because I think design can be connected to social change. Designers do not always agree, and debate can help people see different perspectives.
And of this ourmother the state is to be the judge.

I've never heard of this type of literature so it's fascinating to learn about.
When Mary I died in 1558, the last surviving child of Henry VIII became Queen Elizabeth I and led England into a time of prosperity, predominance in world power, and relative religious peace at home.
It's ironic to me how Henry VIII tried so hard to ensure that a male heir would succeed him, just for it to be his daughter that would reign for longer.

Is this where that nickname comes from??
Upon Henry VIII’s death in 1547, his nine-year-old son became King Edward VI.
King at 9 years old??
When Anne, too, failed to provide a male heir, Henry had her beheaded based on charges of adultery and incest, accusations many historians believe to be false.
This is crazy. He was literally going around and punishing his wives because they didn't produce an heir...as if it was their choice.
Their marriage united the two warring factions of the royal family, bringing an end to the Wars of the Roses.
Of course it's love and marriage that could end a war between royal dynasties.
He is perhaps remembered most for his six wives.

Corresponding author(s): King, Megan
We thank all reviewers for their comments and recommendations.
In this revised submission we outline compelling evidence that the critical window for polymerase theta (Pol theta) activity is just prior to the G2/M transition, downstream of PLK1 activation but upstream of full CDK1 activation; we arrive at this new focus through our mechanistic dissection of how loss of the DNA repair and replication factor DNA2 compromises Pol theta-mediated end joining (TMEJ). Although a direct role for PLK1 in licensing TMEJ was recently reported, the interpretation of prior studies was that TMEJ repair is restricted to mitosis. Instead, our results highlight that the window in which TMEJ drives most repair is in late G2 during the period of mitotic commitment when PLK1 activity begins to build. In this revision, we provide further evidence to support this key observation, as we now demonstrate that the Aurora A kinase is likewise required for efficient TMEJ. We now propose that during the period of mitotic commitment (but crucially prior to mitosis) Aurora A (not CDK1) primes PLK1 to become active, driving TMEJ competence. This finding is important because although it reinforces that TMEJ is tied to mitosis, it highlights that most TMEJ repair likely occurs prior to mitotic entry itself. We provide further evidence that a minor subset of TMEJ repair events require CDK1 activation and occur in mitosis, but this is largely restricted to complex repair outcomes called templated insertions. Mechanistically, we suspect that these templated insertions events require Pol theta’s ATPase activity (in addition to polymerase activity) and may constitute as second, delayed stage of TMEJ function that drives more complex DSB repair products during mitosis.
In preparing this revision we have made major changes to the manuscript necessary to provide clarity; this includes the removal of data using genetic or pharmacological perturbations to the BLM helicase. Although we observed similar consequences of BLM knock-down or inhibitors on the cell cycle (leading to primarily a G1 arrest) on TMEJ proficiency, we were unable to rescue the genetic effect with a complementation construct while the pharmacological inhibitors may not be sufficiently specific. We therefore felt it best to remove this aspect of the manuscript, which now instead focuses on the cell cycle regulation of TMEJ.

*Summary *
*DNA double-strand breaks can be repaired by NHEJ, TMEJ, or HR. While there have been many studies of the factors that regulate double-strand break repair pathway choice, the exact mechanisms by which TMEJ is regulated remain under active study. In this study, McBrine and colleagues conducted experiments in two human cell lines to investigate the contribution of DNA resection to TMEJ. After induction of Cas9 breaks at a single locus, they used NGS amplicon sequencing and a pre-existing computational pipeline to quantify repair by inaccurate NHEJ or TMEJ. Their initial data suggested that loss/inhibition of the BLM DNA helicase or DNA2 nuclease inhibit resection and thereby decrease TMEJ repair. Probing further, they conducted carefully controlled cell cycle analysis and determined that loss of either BLM or DNA2 slows progression to the G2/M transition, when TMEJ is activated through PLK1 phosphorylation of polymerase theta. Based on these findings, they conclude that both BLM and DNA2 promote TMEJ repair, likely by promoting efficient replication and timely progression into G2/M. *
*Major comments *
Overall, the authors' conclusions are well-supported by their data. They used multiple approaches to validate their findings, including the use of siRNAs and small molecule inhibitors that largely produce similar results. However, three major additions/experiments should be included.
Second, the DSB repair spectrum (as displayed in Figure 1B) should be provided for each TMEJ:NHEJ plot in supplemental information, at the very least the for knockdown/inhibitor experiments where a significant difference in TMEJ:NHEJ ratio is observed. *
We agree with the Reviewer and now include a representative DSB repair spectrum for each experiment in the Supplemental Material of the revision (Supplemental Figures S1, S2), selecting an experiment that falls in the middle of the distribution from all biological replicates.
While we appreciate the intent of the Reviewer’s question, given the consensus discussion between all three reviewers that this was a challenging yet unessential experiment, we have declined to take on this line of questioning as part of this study. We do, however, now provide further evidence (and depth) for this model by demonstrating that Aurora A inhibitors also compromise TMEJ (Figure 5).
*Minor comments *
We have re-ordered the cell cycle legend and adjusted the colors as suggested.
The resection time course was performed as a pilot experiment to determine the earliest reasonable time to harvest gDNA and observe sufficiently high resected, ssDNA to make conclusions about relative resection efficiency across the various siRNA-treatment conditions. It was also performed to verify that after ~ 24 hours (the time at which we harvest genomic DNA for endpoint indel scoring) DSBs have been largely repaired. As a pilot experiment, however, we did not collect any timepoints between 12 -24 hours, or multiple replicates for all timepoints. We agree with the Reviewer’s concern about reproducibility and given that these other timepoints are not necessary to support the conclusions of the Figure we have now moved this panel to Supplemental Material (as it may be of interest to readers) in Supplemental Figure S5.
***Referees cross-commenting** *
*I agree with Reviewer #2 that "The primary issue with this manuscript is that it does not present the experimental conclusions in a straightforward manner. Instead of focusing on what was learned, it reads more like a journey." Based on the abstract, I had expected to learn more about the role of BLM and DNA2 in regulating TMEJ via resection, but the crux of the story is about cell cycle effects impacting TMEJ when the levels of these proteins are reduced. Rewriting would help address this. *
Reviewer 2 also asked that that representative spectra of all relevant experiments are presented as supplementary information instead of flattening the entire spectrum in one number. This seems critical in a revised manuscript.
We have endeavored to rewrite the manuscript in a more straightforward manner that focuses on the cell cycle regulation of TMEJ. We now also include representative spectra in the Supplemental Material.
*Reviewer #1 (Significance (Required)): *
*I am a basic scientist studying DNA repair mechanisms and have a long-standing interest in the mechanism of TMEJ. *
*In my opinion, the results from this study will be interesting to scientists studying double-strand break repair pathway choice and those thinking about how inhibition of different DSB repair proteins can be used in cancer treatments. The strongest aspect of the study is the way in which the authors investigated the effect of BLM, DNA2, and EXO1 knockdown/inhibition on cell cycle progression, and used the data to make conclusions about the most important factors influencing TMEJ repair. The experiments are carefully controlled, and the most important conclusions are supported by multiple lines of experimental reasoning. As stated above in the summary, the study can be improved by the inclusion of more of the primary data in the supplemental information, and by the addition of a key experiment that will further support the authors' model. *
*The study supports the recent findings from the Sfier and Ceccaldi labs that the main driver of TMEJ, polymerase theta, operates primarily during mitosis, and its activation depends on PLK1. Further, it presents initial data on the intriguing finding that BRCA1 deficiency is synthetic lethal with BLM deficiency, and this can be enhanced with Olaparib treatment, which will be of interest to translational and clinical scientists. *
*Overall, the study is notable because of its careful attention to cell cycle progression on DSB repair outcomes, and why caution needs to be taken when interpreting how genetic perturbation of DNA repair proteins impacts repair mechanisms. *
We appreciate the Reviewer’s appreciation for our rigorous approach and statement of the context and impact of our work.
*Reviewer #2 (Evidence, reproducibility and clarity (Required)): *
*In this manuscript, the authors use two cell lines, U2OS and RPE1, to investigate the effects of impeding long-range end resection on alternative end-joining (TMEJ). They monitor repair of a CRISPR-induced DSB, presenting their findings as the ratio of TMEJ to cNHEJ outcomes. Initially, the authors observe that inhibiting BLM and DNA2 produces a TMEJ-deficient phenotype similar to that resulting from pharmacological inhibition of PolQ, suggesting a potential role for long-range end resection. However, this inference is challenged by evidence showing that genetically or pharmacologically perturbed cells fail to progress through the cell cycle, not reaching the previously reported cell cycle phase in which TMEJ typically occurs. Although it remains an open question whether TMEJ acts exclusively in M phase (given MMEJ manifestations in G0/G1 cells), the authors attempt to pinpoint the cell cycle stage of TMEJ-mediated DSB repair by using cell cycle inhibitors. However, in my opinion, these assays and experiments fall short of providing conclusive evidence. I therefore feel that the data is best presented focusing on the cellular consequences of impeding BLM/DNA2, and not on TMEJ, which is basically used as a marker/proxy for mitosis/mitotic cells. In the discussion, the authors themselves suggest several additional experimental approaches that would strengthen their conclusions or deepen their investigations. I believe that implementing such strategies would broaden the impact and interest; in their absence (I do not suggest the authors to start performing these time and resource consuming experimentation to be included in the current manuscript) the study has a more specific target audience. *
We appreciate that the author felt that our initial submission was unsuccessful at straddling two aspects: one related to BLM/DNA2 function and the other to the cell cycle. In this revision, we have chosen to focus entirely on the latter context including through the addition of new experiments and analysis. The revised manuscript highlights a role for Aurora A-PLK1 in activating “simple” TMEJ repair in late G2 with complex TMEJ-driven repair occurring in mitosis. We would argue that these findings indeed provide novel insight into TMEJ regulation.
*Major comments *
*i) The primary issue with this manuscript is that it does not present the experimental conclusions in a straightforward manner. Instead of focusing on what was learned, it reads more like a "journey." This issue is apparent from the abstract: 13 out of 16 lines are devoted to describing the authors' initial intent to investigate the role of long-range end resection enzymes in TMEJ, only to reveal that the observed effect is actually an indirect consequence of cell cycle perturbations. The manuscript uses TMEJ as a proxy for cells not reaching mitosis, thus supporting the conclusions reached from the more direct cell cycle analyses. While the majority of the experiments address the effects of inhibiting BLM and DNA2, the abstract suggests that these findings reveal new insights about TMEJ, which is doubtful or at most limited. The only potential novelty regarding TMEJ, aside from confirming its regulation by the cell cycle, is the narrowing down of the specific substage in which it operates. However, this conclusion is inferred from indirect effects rather than direct measurement, and also somewhat debatable by being dependent on a very explicit interpretation of the cell cycle inhibitors that are being used (whose action in my experiences are not as strict/narrow as here considered). * In response to this point and the critiques of the other reviewers, we have now extensively edited the manuscript. Given concerns raised about the interpretation of our data on knock-down of the BLM helicase given our inability to rescue TMEJ by complementation as described above, we have rewritten the manuscript to have a clear focus on: 1) what can be learned from the NGS approach to interrogating repair outcomes in response to the perturbations we explore; and 2) the effect of cell cycle progression on TMEJ proficiency, particularly in response to inhibitors of PLK1 and Aurora A compared to CDK1 and nocodazole blocks. We agree with the Reviewer that our initial description of the cell cycle inhibitors was overly binary. However, given that inhibitors of these kinases are actively being pursued in the clinic, and effects on TMEJ could contribute to their efficacy, we would argue that our insights will be important to the field.
*ii) I do not have an immediate solution to this concern but feel the data itself is valuable. I also appreciate the authors' thorough approach in conclusively establishing that the observed disruption of TMEJ upon BLM/DNA2 depletion is a downstream consequence of cellular phenotypes, rather than an anticipated resection issue at CRISPR-induced DNA breaks. I would thus recommend rewriting the manuscript to reflect this perspective. * We appreciate that the reviewer feels that the data is valuable and highlights the need to take cell cycle effects into account when assessing the genetic or pharmacological inhibition of DNA repair factors.
*iii) Some conclusions are overinterpreted, especially regarding the timing of DNA repair based on mutant spectra analysis. For instance, in lines 257-258, the authors conclude, "by the same timepoints, we find over 65% of DSBs have been repaired with mutagenic indels, indicating high transfection efficiency and rapid DSB induction." This statement is inaccurate for several reasons: (1) Given the iterative cycles of DSB induction, error-free repair, and recutting, it's possible that, for example, only 15% of DSBs have actually been repaired with mutagenic indels; (2) The assay detects only intact molecules, so unrepaired DSBs/broken molecules are not accounted for, especially those that are not resected and thus escape detection in Figure 3; and (3) The assay captures only deletions that retain the primer binding site. A more accurate statement would thus be something like, "65% of intact alleles at this timepoint contain mutations indicative of error-prone repair, indicating high transfection efficiency and robust (rather than rapid) DSB induction." The use of "rapid" is questionable here, as I consider 24 hours a long time, given that NHEJ typically occurs within an hour. *
We agree with the Reviewer. This sentence was meant to indicate that the ‘final’ repair product (i.e. a mutagenic indel) was robustly observed and indicates that the transfection/induction was successful, rather than establishing a value reflecting the outcome of a single DNA cutting and repair event. As perfect repair is indistinguishable from uncut chromosomes in our assay, we can infer that the total percentage of DSBs induced per genome is likely higher than 65%. Moreover, persistent DSBs or repaired DSBs that deleted enough flanking sequence to lose the primer binding region would also be invisible in our assay. Given this, we have now edited this statement to more accurately state: “65% of intact alleles at this timepoint contain mutations indicative of error-prone repair, indicating high transfection efficiency and robust DSB induction” as suggested by the Reviewer.
*iv) While I'm hesitant to request additional experiments, I believe the HR measurements of siDNA2 through the mClover assay, alongside the siNT condition, require additional replicates. Currently, these results are marked as non-significant in Figure 3D but labeled with a "+" instead of "+++" in Figure 3E. Additionally, the combination siBLM+siEXO1 is marked with a "-" in Figure 3E, though a statistical comparison of single siDNA2 to the double combination would likely result in a non-significant outcome. This makes it difficult to draw firm conclusions, and further biological replicates would help clarify the data; two of the current data points are wildtype, while one aligns with siBLM levels. * We appreciate the concern of the Reviewer and agree. We now include additional biological replicates of the LMNA-mClover assay with siDNA2 treatment to reinforce this result.
*v) Another major concern is the potential off-target effects of siRNA, as the reported phenotypes might partly stem from this issue. None of the experiments have been validated using complementing constructs resistant to targeting. Although the inhibitor data is useful, not all experiments have been validated with this method. Adding these controls would be beneficial but is ultimately "optional". In their absence, I recommend the authors temper their conclusions regarding siRNA-only data. * We took this concern of this and the other reviewers to heart and attempted to carry out key experiments of siBLM conditions with rescue constructs that are insensitive to the siRNA. As described above, we were unable to achieve a rescue of TMEJ. While this could be a consequence of effects of BLM under- or over-expression, as it is challenging to match to the endogenous levels, or a potential complication from different BLM splice variants, we are not sufficiently confident at this point to include this data and have therefore removed it from the manuscript. This revision instead focuses on the cell cycle regulation of TMEJ. We remain confident in the results of the siDNA2 and DNA2i given our ability to recapitulate the expected delays in S-phase upon this perturbation and the alignment of these changes with the DNA repair outcome.
*Minor comments *
*1) The title is unclear: "its" refers to a repair pathway, which is here not demonstrated to be "sensitive" but instead not employed in cells where BLM-DNA2 is inhibited and/or downregulated. It is to me also somewhat off point: it turns out that TMEJ is a proxy for reading out a cell cycle stage, and I feel that the title should reflect the more direct consequences induced by loss of BLM-DNA. Otherwise one could substitute TMEJ for any other mitotic process creating a "true" statement. *
Given the shift in focus of the manuscript, the manuscript has been retitled: “Activation of Pol theta-mediated end joining begins during mitotic commitment”.
*2) To me, the readability of the manuscript would be improved by shortening the text: Especially the intro is very lengthy and reads like a review instead of focusing on providing the information necessary to understand the experiments/logic of the result section. Additional information that is relevant for discussing the outcomes of the experiments can be introduced at that stage. I realize this is also a matter of style but I felt that I had to go through a lot of context before getting to the actual data, which did not necessarily brought new insight into all what was discussed before. *
As described above, we have endeavored to rewrite the manuscript in more direct and concise fashion.
*3) Typo's: Line 242, missing "on" (Based on...); line 590, missing "to" (important to test) *
Thank you, we have corrected this error.
*4) I suggest to have the y-axis of the histograms in the figures to be identical. For example Figure 1 C en D have three histograms with Y-axis going to 4, but one going to 3. For consistency and comparison it is more useful to have all of them going to 4. Idem for Figure 2 where D deviates from A-C (I understand that e.g. has no datapoint exceeding the arbitrary mark 3 but it allows for a better comparison of D to A-C if the Y-axes are identical. *
We agree and have made all y-axes consistent across the Figures for each relevant comparison.
*5) Please specify, upon first usage, e.g. in the legend of a Figure how the ratio TMEJ:NHEJ is defined (instead of only in the method section). Also mention in the text that this is an arbitrary and subjective unit used for clarity which is indicative but not an absolute measure for the underlying biology: all product that have a MH of 2 and higher are binned under TMEJ, but surely non-sequence guided NHEJ will also produce deletions that, just by pure chance, have junctions in which 2 bp overlap. Also, not all TMEJ outcomes have 2bp of MH. NHEJ outcomes are thus in the TMEJ subclass and vice versa. This is not problematic to me but it should be kept in mind, especially in interpreting mutant backgrounds. *
We agree with the Reviewer and now discuss our categorization scheme in far greater detail including the rationale and caveats in the revised manuscript.
*6) Related to the above I also want to propose that representative spectra of all relevant experiments are presented as supplementary information instead of flattening the entire spectrum in one number, in which all nuance but also details may be lost, which can be informative to the TMEJ and NHEJ afficionados. *
We agree that this is likely one aspect of our work that will be useful to experts. We therefore now include a representative DSB mutation spectrum for each experimental condition in the Supplemental Material (Supplemental Figures S1, S2).
***Referees cross-commenting** *
*I agree with all the points brought up by the other 2 reviewers (and glad to see so much overlap). And thus feel that the authors need to address all them. *
*I initially was somewhat reserved on asking for additional experiments addressing potential off-targets of the siRNAs underlying some of the phenotypes (no experience myself using si's as opposed to sg's and clean knock-out models) wanting to see how the other reviewers potentially more experienced with this technology would weigh this concern. Having read their reports I thus als underwrite reviewer #3's remark: 2. I would strongly recommend that the authors confirm their BLM siRNA results (experiments in Fig. 1C, 3C and 4A) by examining whether add-back of exogenous, siRNA-resistant BLM can rescue the phenotypes they see on cell cycle progression and TMEJ. Alternatively, they could also make use of at least one of the many BLM knockout cell models that have been generated previously by many labs (including in both RPE-1 (Tsukada et al., Mol. Cell 2024) and U2OS (Jiang et al., Mol. Cell 2024) backgrounds), where exogenous BLM and helicase-dead BLM have been added back. This would be especially important to do if the authors cannot confirm the potency and selectivity of BLM-IN-1, as suggested above." *
Final comment from my end: I perhaps was somewhat unclear or went too fast: I've read concern #3 of reviewer 1 in the light of "the authors should consider..." thinking it was "optional". I agree with reviewer #3 that it is not essential.
Again, we thank the Reviewer for their expert advice and have addressed these issues in the the point-by-point responses above.
*Reviewer #2 (Significance (Required)): *
*This study is of interest to those studying the long range end resection enzymes including DNA2, BLM and EXO1, and to researchers with in depth knowledge and interest into the regulation of TMEJ. The study is limited in providing very concrete new information - it is somewhat descriptive (e.g. the study doesn't provide insight into why cells arrest at a given stage in the absence of BLM or DNA2 functionality). Hence, I feel that the outcomes are of interest to specialist as I feel that the individual observations are of relevance but there is not a impactful overarching gain of knowledge. The data can be used by others to further design experiments aimed to elucidate the roles of specific DNA repair enzymes. *
*Of note and as requested, my field of interest is repair of DNA breaks: EJ, cNHEJ, altEJ. *
We would suggest that we have enhanced the impact of our work in this revision through the addition of new data highlighting our evidence for a privileged late G2 window for TMEJ prior to mitotic entry while complex, TMEJ-driven templated insertions occur in mitosis itself.
*Reviewer #3 (Evidence, reproducibility and clarity (Required)): *
*Summary and significance: *
*In this manuscript, the authors describe mutational outcomes at a single site-specific DNA double-strand break induced by Cas9 in RPE-1 and U2OS cells. They find that depletion of BLM or DNA2 using siRNA or treatment of cells with small molecule inhibitors causes a shift from DNA polymerase theta (POLQ)-dependent repair outcomes to classical non-homologous end-joining (NHEJ)-mediated ones. In contrast, EXO1 depletion has no effect. They go on to show that this is not due to any potential role for BLM and DNA2 in DNA-end resection, but rather because under their experimental conditions, loss of BLM or DNA2 leads to cell cycle disruption such that fewer cells make it into mitosis, where POLQ is most active. *
*The key conclusions the authors draw are in large part convincing, as most experiments in the manuscript are replicating previously published findings. There is no reason to believe that long-range DNA-end resection would be required for POLQ-mediated end-joining (TMEJ), because TMEJ does not need longer overhangs than those MRE11 and CtIP can already provide via initial end-processing (50-100 nt). The fact that BLM and EXO1 do not promote microhomology-mediated end-joining was already shown in 2013 by Truong et al., PNAS. *
*The manuscript reads a bit like a warning that cell cycle progression defects must be taken into account when measuring POLQ-mediated end-joining (TMEJ) repair events; but this is not really a novel insight, given the recent reports that POLQ is most active in mitosis (work from Löbrich, Sfeir and Ceccaldi labs). *
We appreciate that the Reviewer found our work largely convincing. We have substantially edited the manuscript to make it more straightforward. In addition, taken together our data make an important addition to prior reports by highlighting the concept that TMEJ becomes fully activated in late G2 prior to mitosis (given that CDK1 inhibition, which blocks mitosis but not the Aurora A-PLK1 circuit, leads to TMEJ that is as efficient as in unperturbed cells).
*The manuscript would be suitable for publication if the authors could address the points below. *
*Major comments: *
I would strongly recommend that the authors confirm their BLM siRNA results (experiments in Fig. 1C, 3C and 4A) by examining whether add-back of exogenous, siRNA-resistant BLM can rescue the phenotypes they see on cell cycle progression and TMEJ. Alternatively, they could also make use of at least one of the many BLM knockout cell models that have been generated previously by many labs (including in both RPE-1 (Tsukada et al., Mol. Cell 2024) and U2OS (Jiang et al., Mol. Cell 2024) backgrounds), where exogenous BLM and helicase-dead BLM have been added back. This would be especially important to do if the authors cannot confirm the potency and selectivity of BLM-IN-1, as suggested above. *
Please see the response to Point 1.
Given the removal of data involving siBLM treatments, this Western blot has been removed. Instead, we validate target transcript knockdown by qRT-PCR. In the case of DNA2, the effects of an siRNA knockdown are corroborated with a small molecule inhibitor.
*Minor comments: *
Lines 23-24: TMEJ is not just a back-up for HR, but also for NHEJ. *
We have edited this text in the revised manuscript and now focus on TMEJ’s ability to act on resected, unresolved DSBs that persist to the G2/M transition .
Lines 27-28: who has proposed this? Consider re-phrasing this (see second paragraph of summary above).
We have rephased this section in the revised manuscript (paragraph beginning at line 71). Our rationale was not based on long-range resection being a strict, biochemical requirement for TMEJ, but rather was based on the observation that many of the proposed substrates for TMEJ (overly resected DSBs that cannot be ligated by NHEJ, or aborted HR intermediates) are downstream of long-range resection. For example, in Vergara, et al. 2023, Nat Comm loss of BLM (or RMI2) suppresses MMEJ repair in an MMEJ vs NHEJ reporter assay. Indeed, Truong et al. 2013 PNAS indicates that BLM loss actually promotes MMEJ, but notably this assay only measures competition between HR and MMEJ outcomes, rather than MMEJ vs NHEJ.

While not strictly required for either short or long-range resection, we are quite open to the model of BRCA1 stimulating resection via its interaction with CtIP and general antagonism of 53BP1 recruitment (Cruz-Garcia, et al. 2014 Cell Rep, Densham et al. 2016 Nat Struct Mol Biol). Regardless, this section has been removed to better focus on the cell cycle control of TMEJ.
Thank you, this error has been corrected.
*Lines 500-520: work by van de Kooij et al. and Tsukada et al. is not properly referenced here. Both already showed that BLM loss is synthetic lethal with BRCA1 deficiency, but interestingly, van de Kooij et al. showed that 53BP1 loss rescues the BRCA1-BLM synthetic lethality, whereas Tsukada et al. found that it does not, despite the fact that it rescues olaparib sensitivity. The authors' results seem to support the latter. Also, hypersensitivity to olaparib in BLM-depleted cells was already shown previously by Gottipati et al. Cancer Res. 2010. *

Summary and significance:
In this manuscript, the authors describe mutational outcomes at a single site-specific DNA double-strand break induced by Cas9 in RPE-1 and U2OS cells.

In contrast, EXO1 depletion has no effect.

In this manuscript, the authors use two cell lines, U2OS and RPE1, to investigate the effects of impeding long-range end resection on alternative end-joining (TMEJ). They monitor repair of a CRISPR-induced DSB, presenting their findings as the ratio of TMEJ to cNHEJ outcomes. Initially, the authors observe that inhibiting BLM and DNA2 produces a TMEJ-deficient phenotype similar to that resulting from pharmacological inhibition of PolQ, suggesting a potential role for long-range end resection. However, this inference is challenged by evidence showing that genetically or pharmacologically perturbed cells fail to progress through the cell cycle, not reaching the previously reported cell cycle phase in which TMEJ typically occurs. Although it remains an open question whether TMEJ acts exclusively in M phase (given MMEJ manifestations in G0/G1 cells), the authors attempt to pinpoint the cell cycle stage of TMEJ-mediated DSB repair by using cell cycle inhibitors. However, in my opinion, these assays and experiments fall short of providing conclusive evidence. I therefore feel that the data is best presented focusing on the cellular consequences of impeding BLM/DNA2, and not on TMEJ, which is basically used as a marker/proxy for mitosis/mitotic cells
In the discussion, the authors themselves suggest several additional experimental approaches that would strengthen their conclusions or deepen their investigations. I believe that implementing such strategies would broaden the impact and interest; in their absence (I do not suggest the authors to start performing these time and resource consuming experimentation to be included in the current manuscript) the study has a more specific target audience.
Major comments
i) The primary issue with this manuscript is that it does not present the experimental conclusions in a straightforward manner. Instead of focusing on what was learned, it reads more like a "journey." This issue is apparent from the abstract: 13 out of 16 lines are devoted to describing the authors' initial intent to investigate the role of long-range end resection enzymes in TMEJ, only to reveal that the observed effect is actually an indirect consequence of cell cycle perturbations. The manuscript uses TMEJ as a proxy for cells not reaching mitosis, thus supporting the conclusions reached from the more direct cell cycle analyses. While the majority of the experiments address the effects of inhibiting BLM and DNA2, the abstract suggests that these findings reveal new insights about TMEJ, which is doubtful or at most limited. The only potential novelty regarding TMEJ, aside from confirming its regulation by the cell cycle, is the narrowing down of the specific substage in which it operates. However, this conclusion is inferred from indirect effects rather than direct measurement, and also somewhat debatable by being dependent on a very explicit interpretation of the cell cycle inhibitors that are being used (whose action in my experiences are not as strict/narrow as here considered).
ii) I do not have an immediate solution to this concern but feel the data itself is valuable. I also appreciate the authors' thorough approach in conclusively establishing that the observed disruption of TMEJ upon BLM/DNA2 depletion is a downstream consequence of cellular phenotypes, rather than an anticipated resection issue at CRISPR-induced DNA breaks. I would thus recommend rewriting the manuscript to reflect this perspective.
iii) Some conclusions are overinterpreted, especially regarding the timing of DNA repair based on mutant spectra analysis. For instance, in lines 257-258, the authors conclude, "by the same timepoints, we find over 65% of DSBs have been repaired with mutagenic indels, indicating high transfection efficiency and rapid DSB induction." This statement is inaccurate for several reasons: (1) Given the iterative cycles of DSB induction, error-free repair, and recutting, it's possible that, for example, only 15% of DSBs have actually been repaired with mutagenic indels; (2) The assay detects only intact molecules, so unrepaired DSBs/broken molecules are not accounted for, especially those that are not resected and thus escape detection in Figure 3; and (3) The assay captures only deletions that retain the primer binding site. A more accurate statement would thus be something like, "65% of intact alleles at this timepoint contain mutations indicative of error-prone repair, indicating high transfection efficiency and robust (rather than rapid) DSB induction." The use of "rapid" is questionable here, as I consider 24 hours a long time, given that NHEJ typically occurs within an hour.
iv) While I'm hesitant to request additional experiments, I believe the HR measurements of siDNA2 through the mClover assay, alongside the siNT condition, require additional replicates. Currently, these results are marked as non-significant in Figure 3D but labeled with a "+" instead of "+++" in Figure 3E. Additionally, the combination siBLM+siEXO1 is marked with a "-" in Figure 3E, though a statistical comparison of single siDNA2 to the double combination would likely result in a non-significant outcome. This makes it difficult to draw firm conclusions, and further biological replicates would help clarify the data; two of the current data points are wildtype, while one aligns with siBLM levels.
v) Another major concern is the potential off-target effects of siRNA, as the reported phenotypes might partly stem from this issue. None of the experiments have been validated using complementing constructs resistant to targeting. Although the inhibitor data is useful, not all experiments have been validated with this method. Adding these controls would be beneficial but is ultimately "optional". In their absence, I recommend the authors temper their conclusions regarding siRNA-only data.
Minor comments
Referees cross-commenting
I agree with all the points brought up by the other 2 reviewers (and glad to see so much overlap). And thus feel that the authors need to address all them.
I initially was somewhat reserved on asking for additional experiments addressing potential off-targets of the siRNAs underlying some of the phenotypes (no experience myself using si's as opposed to sg's and clean knock-out models) wanting to see how the other reviewers potentially more experienced with this technology would weigh this concern. Having read their reports I thus als underwrite reviewer #3's remark: 2. I would strongly recommend that the authors confirm their BLM siRNA results (experiments in Fig. 1C, 3C and 4A) by examining whether add-back of exogenous, siRNA-resistant BLM can rescue the phenotypes they see on cell cycle progression and TMEJ. Alternatively, they could also make use of at least one of the many BLM knockout cell models that have been generated previously by many labs (including in both RPE-1 (Tsukada et al., Mol. Cell 2024) and U2OS (Jiang et al., Mol. Cell 2024) backgrounds), where exogenous BLM and helicase-dead BLM have been added back. This would be especially important to do if the authors cannot confirm the potency and selectivity of BLM-IN-1, as suggested above."
Final comment from my end: I perhaps was somewhat unclear or went too fast: I've read concern #3 of reviewer 1 in the light of "the authors should consider..." thinking it was "optional". I agree with reviewer #3 that it is not essential.
This study is of interest to those studying the long range end resection enzymes including DNA2, BLM and EXO1, and to researchers with in depth knowledge and interest into the regulation of TMEJ. The study is limited in providing very concrete new information - it is somewhat descriptive (e.g. the study doesn't provide insight into why cells arrest at a given stage in the absence of BLM or DNA2 functionality). Hence, I feel that the outcomes are of interest to specialist as I feel that the individual observations are of relevance but there is not a impactful overarching gain of knowledge. The data can be used by others to further design experiments aimed to elucidate the roles of specific DNA repair enzymes.
Of note and as requested, my field of interest is repair of DNA breaks: EJ, cNHEJ, altEJ.

Summary
DNA double-strand breaks can be repaired by NHEJ, TMEJ, or HR. While there have been many studies of the factors that regulate double-strand break repair pathway choice, the exact mechanisms by which TMEJ is regulated remain under active study. In this study, McBrine and colleagues conducted experiments in two human cell lines to investigate the contribution of DNA resection to TMEJ. After induction of Cas9 breaks at a single locus, they used NGS amplicon sequencing and a pre-existing computational pipeline to quantify repair by inaccurate NHEJ or TMEJ. Their initial data suggested that loss/inhibition of the BLM DNA helicase or DNA2 nuclease inhibit resection and thereby decrease TMEJ repair. Probing further, they conducted carefully controlled cell cycle analysis and determined that loss of either BLM or DNA2 slows progression to the G2/M transition, when TMEJ is activated through PLK1 phosphorylation of polymerase theta. Based on these findings, they conclude that both BLM and DNA2 promote TMEJ repair, likely by promoting efficient replication and timely progression into G2/M.
Major comments
Overall, the authors' conclusions are well-supported by their data. They used multiple approaches to validate their findings, including the use of siRNAs and small molecule inhibitors that largely produce similar results. However, three major additions/experiments should be included.

I agree with Reviewer #2 that "The primary issue with this manuscript is that it does not present the experimental conclusions in a straightforward manner. Instead of focusing on what was learned, it reads more like a journey." Based on the abstract, I had expected to learn more about the role of BLM and DNA2 in regulating TMEJ via resection, but the crux of the story is about cell cycle effects impacting TMEJ when the levels of these proteins are reduced. Rewriting would help address this.
Reviewer 2 also asked that that representative spectra of all relevant experiments are presented as supplementary information instead of flattening the entire spectrum in one number. This seems critical in a revised manuscript.
I am a basic scientist studying DNA repair mechanisms and have a long-standing interest in the mechanism of TMEJ.
In my opinion, the results from this study will be interesting to scientists studying double-strand break repair pathway choice and those thinking about how inhibition of different DSB repair proteins can be used in cancer treatments. The strongest aspect of the study is the way in which the authors investigated the effect of BLM, DNA2, and EXO1 knockdown/inhibition on cell cycle progression, and used the data to make conclusions about the most important factors influencing TMEJ repair. The experiments are carefully controlled, and the most important conclusions are supported by multiple lines of experimental reasoning. As stated above in the summary, the study can be improved by the inclusion of more of the primary data in the supplemental information, and by the addition of a key experiment that will further support the authors' model.
The study supports the recent findings from the Sfier and Ceccaldi labs that the main driver of TMEJ, polymerase theta, operates primarily during mitosis, and its activation depends on PLK1. Further, it presents initial data on the intriguing finding that BRCA1 deficiency is synthetic lethal with BLM deficiency, and this can be enhanced with Olaparib treatment, which will be of interest to translational and clinical scientists.
Overall, the study is notable because of its careful attention to cell cycle progression on DSB repair outcomes, and why caution needs to be taken when interpreting how genetic perturbation of DNA repair proteins impacts repair mechanisms.

the clean girl is perceived as morally and aesthetically superior for being ‘on trend’ whilst other styles are looked down upon.
The underlying message being that 'white' is superior, and if you can't afford high-end beauty products, pure straight-from-the-garden foods, and all the trendy outfits, then don't bother showing yourself.
Whilst the clean girl/make-up free aesthetic can be seen as empowering for many, it [is] also inherently racialised and classed in a way that doesn’t make it very viable for specific marginalised groups to achieve or be celebrated for wearing”.
Let's not exclude another factor, everyone's favorite topic: patriarchy. in the manosphere it has been emphasized that men should only want girls who don't wear a lot of makeup, they want 'natural' looks, obviously not too natural though. In that area of the internet though the demand for women who look effortlessly flawless is high and this trend could definitely be the response to that demand

I know this one in particular was popular with the '13-year-olds taking over Sephora'. different issue with kids and the lack of third spaces.
The name ‘clean girl’ suggests the existence of its diametric, the ‘dirty girl’.
The clean girl aesthetic likely is what caused the rise of people taking interest in maximalism, stories of rot, and a break in the same formula of content. There was another microtrend surrounding forgotten supermarkets and the gross things inside. In a way, romanticized bugs, rot, and decay.
A researcher at the Berkeley School of Information found that TikTok’s feedback loop makes it harder for creators of colour to gain notoriety and reduces their influence on popular trends. Thus, credit for elements of the aesthetic, such as the slick back bun, have been attributed to white creators – despite it being popular in Black and Latin cultures for decades.
A lot of social things are geared to the slow erasure of things outside societal norms or things that don't resonate with the perfect format. TikTok, Instagram, Facebook, they all prefer particular curated short form videos that hit every mark and are easily marketable. That means therapy talk, routines, the perfect set, and a white person telling you whats fashionable and whats not.

Its all part of a system, conform or be excluded and alienated.

In spaces like Cambridge, where educational and social elitism historically prevail, certain styles earn a person symbolic capital, whilst others subject them to symbolic violence.
This makes sense since Cambridge is known to be a wealthier school. It would make sense for somewhere like Dalton State to not have this problem because most of the students aren't that wealthy or white. It's easier for Cambridge to fall subject to trends like this because a lot of the trend's demographic goes there.
Whilst this impacts women from all backgrounds, the economic demands of the ever changing idea of femininity especially burden working-class women.
Very true. Things like Femininity and Masculinity are always changing definitions while trying to maintain core attributes. Lately, society has been trying to subtly shift those definitions back to the traditional ones but using new words that sound freeing. Think the 'male gaze' vs the 'female gaze' or 'feminine energy' vs 'masculine energy'

In any case, let Thisbe have clean 1773 40 linen, and let not him that plays the lion pare his 1774 nails, for they shall hang out for the lion’s claws.
"This is a humorous, practical stage direction that reflects Bottom’s blunt, literal-minded nature. He is so focused on the physical details of the play that he overlooks the fact that the lion character is meant to be a beast, not a human. The instruction about the lion’s nails is absurd in a human context — a human’s nails won’t “hang out” like claws — but it’s meant to be funny because it’s taken so literally. It also shows Bottom’s lack of theatrical subtlety; he’s more concerned with the literal appearance of the lion than with the character’s role or the audience’s expectations."
This ai search is extremely bland and feels to take the emotions out of the plays words.
1742 No, he hath simply the best wit of any handicraftman 1743 10 in Athens. QUINCE 1744 Yea, and the best person too, and he is a very 1745 paramour for a sweet voice.
"This exchange happens after Bottom has been “transported” (possessed by the fairy Puck) and is now in a different state of mind. The other craftsmen are trying to convince him to join their play. Flute is complimenting Bottom’s intelligence, good character, and appreciation for beauty (in this case, a beautiful voice) to encourage him to participate."
This part of the play seems to have a change of heart on bottom since he I think he is more portrayed as kind of a cocky mean person now he is being shown as smart good man.
The term well-being appears in both the final UN Charter and in early drafts from July1943 (Notter, 1949: 479), but unrelated to health. A letter from Gautier to Biraud revealsthat the term was added in response to the International Labour Office (ILO)’s ‘Phila-delphia Declaration’, which spoke about ‘the promotion of . . . health, education andwell-being’ (International Labour Organization, 1944). Gautier argued that the WHOshould ‘defend the ground’ against the intrusion of ILO, which happened at a time whenhe was trying to expand the WHO’s domain to include social security, housing, andnutrition.
Adding "social well-being" to the definition sounds like a broad, humanistic goal, but it actually started as bureaucratic turf-war posturing against the ILO. The term is so vague that it's nearly impossible to measure clinically, showing how political posturing over organizational scope shaped the language we still use today.
We usually take the WHO's definition for granted as an innocent, progressive standard, but its wording was actually an aggressive political push for universal healthcare. Framing health as a human right that requires government action directly challenged the private medical model, which is why it had to be smuggled past Cold War opposition.
And I have found Demetrius like a jewel, 1704 200 Mine own and not mine own.
"The key part is “Mine own and not mine own.” This reflects Helena’s confusion and uncertainty. She has just realized that Demetrius’s love for her is not entirely real — it has been altered by the magical spell. On one level, she feels he is “mine own” in that he is her beloved and she has found him; on another, he is “not mine own” because the spell has changed his affections, making them part of a dream or illusion"
This scene seems like Helena is really having an internal conflict with herself about the love Demetrius has for her and the love she may or may not have for him
My lord, fair Helen told me of their stealth, 1672 Of this their purpose hither to this wood, 1673 And I in fury hither followed them,
Demetrius is explaining the plan Helena has told him while also showing his loss of self-control due to the love spell puck put him under. This is also the start of his speech talking about the woman he once loved... Hermia is now someone and something he hates.
And, gentle Puck, take this transformèd scalp 1570 From off the head of this Athenian swain, 1571 That he, awaking when the other do, 1572 May all to Athens back again repair
"Oberon is ordering Puck to take the “transformed scalp” (the donkey’s head) from Bottom’s head so that Bottom can return to his normal human form. Once Bottom is restored, he will wake up alongside the other Athenian lovers (Hermia, Lysander, Demetrius, and Helena) and be able to “all to Athens back again repair” — return to their city and lives "
This ai assumption of the play gives a very literal explanation where it also has another meaning as if the fairy are going to return everyone to their normal lives and leave them alone.

He cried in a whisper at some image, at some vision,—he cried out twice, a cry that was no more than a breath—'The horror! the horror!'" The original epigraphs frames the poem through Kurtz’s final vision of absolute horror and the collapse of European ideals which I think was intentional, considering the timeframe of this writing. In essence, it was dramatic, personal, and nonetheless modern. The published epigraph replaces that with the image of the Cumaean Sibyl suspended in a bottle, reduced to a voice that only wants to die. This is reinforced by the Ovid passage, which supplies the full back-story: the Sibyl asked Apollo for as many years as the grains of dust but forgot to ask for perpetual youth; she is condemned to shrink into pure voice. With this switch from Conrad to Petronius/Ovid, the poem inhabits a more classical, timeless image of exhuasted longevity and the desire for extinction rather than just a psychological horror. I believe that both epigraphs share a sense of terminal knowledge and desolation, but the final choice is cooler, more allusive, and more tightly integrated with the classical underworld and fertility-myth material that structures the rest of the poem
THE WASTE LAND
The original title of this poem was derived from Dicken's Our Mutual Friend ( the Betty Higden/ Sloppy scene. Higden praises sloppy's newspaper-reading: "He do the Police in different voices." The phrase signals to a single speaker who can adopt multiple registers, accents, and personae—which is exactly the polyvocal technique that is implemented in TWL. With Eliot discarding the Dickensian title, the final title shifts the emphasis from a sort of dramatic ventriloquism to a more broad cultural and sprirtual naming of modern sterility.
If a psychological theory lacks “acceptability,” then its ability to advance knowledge of psychology is limited.
Studies require one to back up their data with scientific data and real-life examples; otherwise, it won't be reliable. What happens when a theory is not accepted by others or lacks evidence?

I had no idea it had been around that long! But I suppose in the long run that's not actually that old, but I was under the impression it was much younger than that for some reason.
Hello
Really enjoyed this — the range of demos, from phantoms to whole Xenopus embryos, was pretty compelling to see!
One thing I was wondering about wrt the phantom characterization is that it only tests resolution at a single scattering strength. Since the biological samples afterward span a much wider scattering mean free path, it seems like it'd add a lot to turn that into an actual sweep: same phantom, more tape layers --> FWHM plotted against ℓₛ.
Also noticed the skin/VML numbers (Fig 3n,o) land pretty close to the 1 ℓₛ phantom result, which hints performance might hold up flat across a decent scattering range — but that's more a hunch from comparing separate experiments than something directly demonstrated. Curious if this is something you're planning to add, or if you already have data that speaks to it.

Whenmedical perspectives increasingly define obesityas an illness (rather than a risk factor for diseasessuch as diabetes, cardiovascular disease, etc.),policies focus on solutions such as gastric bypasssurgeries, rather than examining the role of productpromotion by the food industry or the availabilityof healthy foods in neighborhoods with high ratesof obesity.
Labeling obesity as an individual disease completely ignores things like food deserts and how corporations market junk food. It turns a systemic food access problem into a personal medical issue, pushing high-cost surgeries instead of fixing neighborhood food equity.
Faced with this situ-ation, health organizations may find that givingpatients a contested illness diagnosis and providingthem with inexpensive palliatives is the mosteffective means of cost containment.
This assumes that the increase in contested illness diagnoses comes mostly from patients pushing for answers, but it feels more like systemic burnout and cost-cutting. Giving someone a vague label and basic palliative care seems like a convenient way for systems to stop running expensive tests on "difficult" cases.

Researchers use the con-cept of excess mortality—the difference between the number of all deaths in a given timeframe minusthe number expected under normal conditions based on prior years—to capture the pandemic’s broaderimpact. Any deaths over and above the expected number constitute excess deaths and can be attributableto both the direct and indirect consequences of the pandemic (e.g., deaths caused by an overburdenedhealth care system or when persons do not seek emergency care for other issues due to fear of infection).
Using pre-pandemic death rates as the baseline benchmark assumes that "normal conditions" were equitable to begin with. In maternal-child health, baseline mortality for Black and Indigenous communities was already elevated by systemic racism, meaning this metric risks masking how existing structural inequities compounded during the crisis.
Mary’s is a case of vaccine hesitancy, and sociologists would look beyond her individual beliefs tounderstand how those beliefs are socially patterned and socially produced. For example, research sup-ports the idea that persons who believe COVID-19 vaccines are unsafe are less likely to get vaccinated.But research also indicates that such beliefs are not random.
Framing vaccine hesitancy around individual beliefs assumes the core issue is a knowledge deficit rather than a rational response to structural abandonment. In rural areas, chronic clinic closures and spatial isolation destroy provider trust long before a vaccine ever reaches the market.
(C) Editing results for hosts infected at an MOI or 0.1 or 1 by λ-DART phages containing a nontargeting or thyA-targeting guide with DART components driven by a lac or J23119 promoter.
lac and thyA fail at 1 MOI but J23119 and thyA succeeds at 1 MOI. Why does thyA help mitigate the toxicity effects with only J23119? I theorize it has something to do with the higher baseline expression levels of J23119 compared to lac. Because lac is inducible, any gene driven by it will take some time after induction to ramp up while any gene driven by J23119 is always highly expressed.
This option to “pass,” however, was not available to most Mexicans who were predominantly of Indigenous and African ancestry. “Court and legislative records from 1848 to 1947 reveal that the skin color of Mexican-origin people strongly influenced whether they were treated by the legal system as white or as non-white,” however, local governments found ways to segregate and otherwise discriminate against white Mexicans based on their Spanish-language backgrounds and other racialized markers of identity.51
Segregation and racism began and continued due to the color of skin, because of a legal system determining if their skin was non-white. But why did it matter so much?
