Causation was demonstrated, in that addition of palmitate or mevalonate (products of 3-hydroxy-3-methylglutaryl-CoA reductase and fatty acid synthase, FASN) could partially restore prostate cancer cell growth even in the presence of MT 63–78, while no effect was seen in cells untreated with MT 63–78. This evidence concerns the gene FASN and Familial prostate cancer.
