Mix culture assay results demonstrated a selective AMG510 inhibitory effect when targeting KRAS G12C in colon cancer cells. (A) The RPR of G12C transgenic cells decreased in an AMG510 concentration-dependent manner. (B) Following AMG510 administration, the RPR of the G12C was greatly reduced. There was a significant difference in G13D; however, there was a slight decrease in RPR. No changes in RPR were observed in KRAS wild type or other KRAS mutations. *P<0.05 and **P<0.01 vs. drug-free control. KRAS, Kirsten rat sarcoma 2 viral oncogene homolog; RPR, relative proliferation ratio; n.s., not significant.
