The 37 gastric cancer cell lines, which includedeight KRAS mutant cell lines (AGS, SNU601, SK4, SNU1, NCC24, SNU668, YCC2 and NCC59) in this study also showed similar results in that KRAS mutant cell lines had higher sensitivity to BI-2536 and volasertib (Figure 4b). Here, KRAS is linked to gastric cancer.
