Lovastatin induces apoptosis in a metastatic ovarian tumour cell line.
Lovastatin is a very specific and potent inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase, which regulates a rate-limiting step in the cellular synthesis of isoprenoid and cholesterol. In this study, we demonstrate that treatment of rat ovarian metastatic OV1N cells with lovastatin induces apoptosis. Furthermore, apoptotic death of lovastatin-treated OV1N cells can be prevented by the addition of either mevalonic acid (an immediate metabolite of HMG-CoA) or farnesyl pyrophosphate (one of the downstream products of mevalonic acid metabolism). However, metabolic derivatives of farnesyl pyrophosphate failed to prevent the apoptotic effect of lovastatin on cells. Therefore farnesyl pyrophosphate appears to be important for cell survival and the relationship of this compound to protein farnesylation and apoptosis induction is discussed.[1]References
