RBMS1 and gastric cancer: RBMS1 can promote gastric cancer metastasis through autocrine IL‐6/JAK2/STAT3 signaling.[13] Meanwhile, loss of RBMS1 promotes anti‐tumor immunity through enabling PD‐L1 checkpoint blockade in triple‐negative breast cancer.[14] These data suggest that RBMS1 is a pro‐oncogene.
