We were interested in ascertaining whether the suppression of TNFR in gastric cancer cells could increase the efficacy of anticancer drugs, and it was confirmed that oxaliplatin and cisplatin displayed a greater increase of the inhibitory efficacy of cell proliferation in the siTNFR1-treated group compared with the control group (Supplementary Figure S2). The gene discussed is TNFRSF1A; the disease is gastric cancer.
