Cytotoxic effects of statins and thiazolidinediones on meningioma cells.

Statins are inhibitors of the cholesterol synthesis pathway with pleiotropic effects, while thiazolidinediones (TDZ) are peroxisomal proliferator activator receptor γ (PPAR-γ) agonists with potent proapoptotic activity. For both groups of substances a cytotoxic effect against several human tumors is presumed. Direct comparison of several statins and TDZ has not been performed on meningioma cells until now.
