...we found that OTS514 and 5-FU could induce apoptosis in KRASG12C cells, and the combination of OTS514 and 5-FU showed strong synergistic effect in apoptosis induction...we found that the combination of OTS514 + 5-FU induced more apoptotic cells and showed a more profound inhibition on cell proliferation in KRASG12C cells when compared with KRASWT cells (Figure 6E,F). The synergistic effect of OTS514 and 5-FU was also validated in xenograft tumour model (Figure 6G)...
