In America, of course, we don’t have that kind of state coercion. There are currently no laws that shape what academics or journalists can say; there is no government censor, no ruling-party censor. But fear of the internet mob, the office mob, or the peer-group mob is producing some similar outcomes. How many American manuscripts now remain in desk drawers—or unwritten altogether—because their authors fear a similarly arbitrary judgment? How much intellectual life is now stifled because of fear of what a poorly worded comment would look like if taken out of context and spread on Twitter?

Neonatal mice deficient in TLR4 have markedly diminished LGR5+ stem cell proliferation and diminished crypt fission.

Low dose, high MW endogenous HA binding to TLR4 may preferentially promote PGE2 production, whereas high dose low MW exogenous HA or LPS or LTA binding to TLR4 may preferentially promote CXCL12 production.

In contrast, TLR4 activation by LMW-HA requires a TLR4 and MD2 complex but is independent of CD14 and LPS binding protein.

TLR4 activation by LPS requires a TLR4 and MD2 complex, LPS binding protein, and CD14 which delivers LPS to the TLR4 and MD2 complex.

This may be the product of endogenous HAs of different molecular weights binding separately to CD44 and TLR4 or it may be the product of HA binding to a CD44 and TLR4 complex.

Hyaluronic acid binding to TLR4 in pericryptal macrophages results in cyclooxygenase2- dependent PGE 2 production, which transactivates EGFR in LGR5+ crypt epithelial stem cells leading to increased proliferation.

Among the PAMPs are lipoteichoic acid (LTA), a component of gram positive bacteria that binds TLR2, and LPS, a component of gram negative bacteria that binds TLR4.

Although both LMW-HA and LPS bind to TLR4, the results of TLR4 activation by LMW-HA and LPS are not identical.

Low dose, high MW endogenous HA binding to TLR4 may preferentially promote PGE2 production, whereas high dose low MW exogenous HA or LPS or LTA binding to TLR4 may preferentially promote CXCL12 production.

The presence of CD44 also enhances the effects of HA binding to TLR4 although the presence of CD44 is not required for HA activation of TLR4.

HA binds to CD44, TLR2, TLR4, the receptor for HA mediated motility (RHAMM), layilin, lymphatic vessel endothelial HA receptor- 1 (LYVE-1), and HA receptor for endocytosis.

EGFR can activate beta-catenin via the receptor tyrosine kinase-PI3K-Akt pathway.

Although the evidence suggests that EGFR activation in response to TLR4 signaling is mediated by PGE2, it is also possible that TLR4 signaling promotes EGFR activation through the production of amphiregulin, epiregulin or other EGFR ligands.

Administration of exogenous TLR2 or TLR4 agonists activates TLR2 and TLR4 on pericryptal macrophages inducing CXCL12 production with migration of cyclooxygenase2 expressing mesenchymal stem cells from the lamina propria of the villi to a site adjacent to LGR5+ epithelial stem cells.

This suggests that TLR2 and TLR4 signaling driven by PAMPs from commensal bacteria promotes epithelial proliferation during wound repair in the colon.

In contrast to wound repair, where inflammation accompanies enhanced epithelial proliferation driven by TLR2 and TLR4 activation, in intestinal growth TLR4 activation promotes epithelial proliferation in the absence of inflammation.

TLR4 activation by LPS and LMW-HA require different accessory molecules.

Although both LMW-HA and LPS bind to TLR4, the results of TLR4 activation by LMW-HA and LPS are not identical.

In human biliary carcinoma cells in vitro, addition of LPS initiates a positive feedback loop of TLR4 activation, PGE2 production through COX-2 and EGFR activation.

In this pathway, TLR4, which is usually associated with innate immunity, is activated not by the microbial product LPS, but by HA, a host molecule.

TLR4 activation by HA also plays a role in wound repair.

Despite these suggestions there is good evidence that endogenous HA activates TLR4 and promotes growth even though most of the endogenous HA is in the high MW form.

There are suggestions that TLR4 is preferentially activated by the low MW form of HA.

TLR4 activation by HA drives LGR5+ epithelial stem cell proliferation and crypt fission in normal growth in the intestine and colon.

The presence of CD44 also enhances the effects of HA binding to TLR4 although the presence of CD44 is not required for HA activation of TLR4.

In the first pathway (XREF_FIG), intestinal and colonic growth is regulated by endogenous HA activating TLR4 on pericryptal macrophages resulting in the release of PGE2 which promotes LGR5+ stem cell proliferation, crypt fission and intestinal elongation.

A study of pulmonary injury induced by intratracheal bleomycin demonstrates the role of HA activation of TLR4 in sterile injury.

Taken together these studies addressing the cellular location of the TLR4 signaling that drives growth and wound repair and the nature of the relevant TLR4 ligand suggest that HA activation of myeloid TLR4 mediates intestinal and colonic growth and wound repair.

This suggests that TLR4 activation by endogenous HA promotes healing in DSS colitis.

TLR4 activation by HA also affects the immune response in ischemia- reperfusion injury in the kidney and in acute allograft rejection in a skin transplant model.

TLR2 and TLR4 activation by HA mediates wound repair in the bleomycin model of lung injury.

Wound repair mediated by HA activation of TLR2 and TLR4 is also seen in the lung.

In this pathway, TLR4, which is usually associated with innate immunity, is activated not by the microbial product LPS, but by HA, a host molecule.

Based on the growth studies, it is likely that EGFR activation by PGE2 is also the mechanism of the increased epithelial proliferation in the repair phase of DSS colitis.

In growth EGFR activation by PGE2 accounts for about 30% of LGR5+ cell proliferation.

Although the evidence suggests that EGFR activation in response to TLR4 signaling is mediated by PGE2, it is also possible that TLR4 signaling promotes EGFR activation through the production of amphiregulin, epiregulin or other EGFR ligands.

In accordance with the ability of mutant SPOP to repress the function of endogenous wild type SPOP in a dominant negative manner, the over-expression of mutant SPOP (SPOP-Y87C, -F102C, -W131G, -F133S) phenocopied the effect of SPOP knockdown on ERG mediated invasion in PC3 cells.

In line with these findings, gene ontology analysis of AR-ERG co-bound gene signature in VCaP cells indicated that the most striking transcriptional changes were linked to cellular differentiation and cell cycle arrest that are directly induced by DHT and repressed by ERG (e.g., HOXA genes, CDKN1A and p21, Fig.

In line with these findings, gene ontology analysis of AR-ERG co-bound gene signature in VCaP cells indicated that the most striking transcriptional changes were linked to cellular differentiation and cell cycle arrest that are directly induced by DHT and repressed by ERG (e.g., HOXA genes, CDKN1A and p21, Fig.

Similarly, knockdown of SPOP in VCaP cells reduced cell growth in 3D cell culture and impaired ERG mediated gene transcription.

The oncogenic effect was paralleled by an increase in the expression of the oncogenic transcription factors MYC and HOXB13 and a decrease in the cell cycle inhibitor p21 as seen in an organoid line derived from Spop F133V -mutant transgenic mice 13.

ZMYND11 induces AR signaling pathway and represses ERG activity.

In accordance with the ability of mutant SPOP to repress the function of endogenous wild type SPOP in a dominant negative manner, the over-expression of mutant SPOP (SPOP-Y87C, -F102C, -W131G, -F133S) phenocopied the effect of SPOP knockdown on ERG mediated invasion in PC3 cells.

We found two degron sequences that were required for efficient SPOP mediated ubiquitylation and protein degradation.

Moreover, knockdown of ERG reduced SPOP protein levels in VCaP cells, while forced expression of a DeltaERG led to the upregulation of SPOP mRNA and protein levels in PC3 cells.

Thus, we wondered if ERG itself may directly upregulate SPOP transcription to support its own oncogenic activity.

Indeed, knockdown of TRIM24 by two short-hairpin RNAs partially reverted the growth inhibition mediated by mutant-SPOP in VCaP cells and reduced AR signaling, while over-expression of AR was sufficient to decrease cellular growth.

In agreement with the established repressive function of ZMYND11 on ERG, we found that over-expression of HA-ZMNYD11-DM2 was sufficient to repress ERG induced invasion and established target genes in PC3 cells.

We then asked if the elevated SPOP levels in the context of forced DeltaERG expression have a functional impact on the oncogenic activity of DeltaERG in the androgen independent PC3 cells, in which ERG promotes tumor cell invasion 31.

ZMYND11 induces AR signaling pathway and represses ERG activity.

We postulated that ZMYND11 upregulation could contribute to the synthetic sick relationship by repressing the ERG oncogene 's transcriptional activity or enhancing AR signaling.

Mutant SPOP induced androgen receptor signaling antagonizes ERG activity.

Conversely, we assessed the consequence of ERG overexpression in LNCaP cells under low DHT levels where mutant SPOP triggers AR signaling and tumor growth XREF_BIBR, XREF_BIBR.

Taken together, the data imply a mutual incompatibility of mutant SPOP induced AR signaling and the function of the ERG oncogene.

The low nutrient concentrations and high oxygen concentrations measured in these samples support the influence of the Polar Surface Water or the Polar Intermediate water from the EGC.

Parthenolide has previously been shown to inhibit NLRC4 dependent caspase-1 activation 15, although it did not do so in these experiments (XREF_FIG).

MCC950 blocks NLRP3 induced ASC oligomerization.

Water fluxes through pressurized root systems treated with nitrogen and low oxygen (< 2% O (2)), elevated CO (2) (20% CO (2)), and low O (2) with elevated CO (2) concentrations were reduced to 40, 51 and 58%, respectively, of J (v) of plants aerated with ambient air.

The probability for the occurrence of sulphur plumes is enhanced in years with a lower annual mean of upwelling intensity, decreased oxygen supply associated with decreased lateral ventilation of bottom waters, more southern position of the Angola Benguela Frontal Zone, increased mass fraction of South Atlantic Central Water and stronger downwelling coastal trapped waves.

Moreover, TFRC activated PTEN induced kinase 1 (PINK1) signaling and induced mitophagy; iron-uptake-induced upregulation of acyl-CoA synthetase long chain family member 4 (ACSL4) was required for mitophagy activation and glutathione peroxidase 4 (GPX4) degradation.

The precise mechanism of how LASP1 promotes PTEN ubiquitination still remains elusive 53.

One study showed that Nuclear Receptor Binding SET Domain Protein 2 (NSD2)-mediated dimethylation of PTEN promotes 53BP1 interactions and subsequent recruitment to sites of DNA-damage sites 75.
