We found that G3BP1 depletion and capecitabine treatment had synergistic effects in markedly reducing subcutaneous tumour growth compared to that in the control group, indicating that shG3BP1 gastric cancer cells were likely more sensitive to chemotherapy following capecitabine treatment (Fig. 2f, g and Supplementary Fig. 2e, f). The gene discussed is G3BP1; the disease is gastric cancer.
