Statins have been used successfully in the treatment of hypercholesterinaemia. Moreover, in vitro studies have shown that statins can trigger apoptosis in a variety of tumor cell lines. In the present study we analysed the effect of mevastatin -a novel inhibitor of HMG-COA reductase, the rate-limiting enzyme of the mevalonate pathway- on U266 human myeloma cells. Apoptosis induced by mevastatin was associated with increased caspase activity and depolarisation of the mitochondrial membrane. Expression of Bcl-2 mRNA and protein was down-regulated, with no change in Bax or Bcl-XL protein production. The mitochondrial program was supported by caspase-8 and cleaved-Bid activity. None of the antibodies neutralizing the death-ligand/death-receptor pathway-TRAIL-R2Fc, anti-TNF-α, anti- FASL(NOK-1)- influenced the mevastatin-induced apoptosis. Mevastatin also stimulated shedding of syndecan-1 from the surface of myeloma cells. The apoptosis inducing effect of mevastatin could be considered as a potential participant in a complex antitumor protocol.
