MET also exerts an antitumor action in vivo against colorectal tumors by acting on the tumor microenvironment and improving immunotherapy efficacy [164]; MET inhibits the cell growth of cutaneous squamous cell carcinoma by promoting apoptotic mechanisms and decreasing immunosuppression [173], and MET blocks the growth of human gastric cancer cell lines by promoting apoptosis [175]. This evidence concerns the gene MET and gastric cancer.
