Farnesol is a catabolite of the cholesterol biosynthetic pathway that preferentially causes apoptosis in tumorigenic cells. Phosphatidylcholine (PC), phosphatidic acid (PA), and diacylglycerol (DAG) were able to prevent induction of apoptosis by farnesol. Primary alcohol inhibition of PC catabolism by phospholipase D augmented farnesol-induced apoptosis. Exogenous PC was unable to prevent the increase in farnesol-induced apoptosis by primary alcohols, whereas DAG was protective. Farnesol-mediated apoptosis was prevented by transformation with a plasmid coding for the PA phosphatase LPP3, but not by an inactive LPP3 point mutant. Farnesol did not directly inhibit LPP3 PA phosphatase enzyme activity in an in vitro mixed micelle assay. We propose that farnesol inhibits the action of a DAG pool generated by phospholipase D signal transduction that normally activates an antiapoptotic/pro-proliferative target.
