PT suppresses the 12-O-tetradecanoylphorbol-13-acetate-induced invasion of HepG2 cells through the inhibition of mitogen-activated protein kinase and phosphoinositide 3-kinase pathways8 and inhibits breast cancer metastasis through the microRNA-mediated downregulation of the epithelial-to-mesenchymal transition25. This evidence concerns the gene WNK2 and breast carcinoma.
