TRPC6 and hepatocellular carcinoma: In human hepatocellular carcinoma cells, transforming growth factor beta (TGFβ) is a mediator of motility, invasion, and metastases via the stimulation of Na+/Ca2+ exchanger 1 (NCX1), and TRPC6 activation regulates TGFβ, thus inducing the formation of a TRPC6/NCX1 molecular complex [124].
