KRAS and colorectal carcinoma: To evaluate the effects of these inhibitors on CRC cell proliferation, we performed XTT cell proliferation assay on KRAS mutant CRC cell lines (SW480, SW620, HCT116, and DLD‐1) and KRAS wt CRC cells (Caco‐2 and HKe3‐KRASWT/WT+) following the treatment with the JPH203 and V‐9302.
