Sanguinarine (1) inhibits the proliferation of BGC-823 gastric cancer cells by downregulating the expression of miR-96-5p and miR-29c-3p and upregulating the expression of MAP4K4, pMEK4, and pJNK1 protein in gastric cancer cells BGC-823 [19]. This evidence concerns the gene MAP4K4 and gastric cancer.
