Tang et al. observed that stigmasterol could effectively inhibit the proliferation of gastric cancer cells MGC-803 in a dos-dependment manner and also induced apoptosis in gastric cancer MGC-803 cells by regulating the apoptotic signaling pathway, activating caspase3 and caspase9, upregulating Fas and Bax gene expression, and downregulating Bcl-2 protein (Tang, 2021). Here, FAS is linked to gastric cancer.
