Next, we determined whether metformin had superior antitumor activity in KRAS-mutated CRC cell lines to those with KRAS wild type through a cell-viability test. As shown in SI Appendix, Fig. S2A, metformin inhibited the
[Paragraph-level] PMCID: PMC7293710 Section: RESULTS PassageIndex: 7
Evidence Type(s): Predictive, Oncogenic
Justification: Predictive: The passage discusses how the KRASG12V mutation correlates with increased sensitivity to the antiproliferation therapy of metformin, indicating a predictive relationship between the variant and treatment response. Oncogenic: The KRASG12V mutation is implicated in tumor development as it is mentioned in the context of its effect on cell viability and sensitivity to therapy in colorectal cancer cell lines.
