The KRAS G12C mutation drives cancer cell growth and survival1
KRASG12C is a glycine-to-cysteine amino acid substitution driven by a point mutation in the KRAS coding sequence2
See below for a deeper look into the role of KRAS G12C in cancer3
KRAS G12C oncogenic signaling
- In normal cells, KRAS cycles between an active and inactive state to regulate downstream signaling pathways, leading to cellular proliferation, differentiation, and survival4
- In tumor cells, the active GTP-bound form of KRASG12C is favored, resulting in oncogenic signaling and tumorigenesis1

Understanding the role of KRASG12C in NSCLC warrants further investigation
