G3BP1 and gastric cancer: After depleting G3BP1 in gastric cancer cells (Supplementary Fig. 2a), we examined the IC50 values of these two drugs in suppressing gastric cancer cell growth and observed that depletion of G3BP1 markedly decreases the IC50 values of both capecitabine and oxaliplatin in gastric cancer cells (Fig. 2a and Supplementary Fig. 2b).
