Abstract

Simvastatin is an antilipemic drug that promotes inhibition of HMG-CoA reductase. Simvastatin can also inhibit the formation of other products, such as isoprenoids, conferring additional benefits to this drug, which include antiproliferative, anti-invasive and pro-apoptotic effects. This study was carried out with the aim of evaluating the mutagenic/recombinogenic effect of simvastatin as well as the possible modulatory effects of this statin on the DNA damage induced by doxorubicin (DXR). This analysis was performed using the somatic mutation and recombination test (SMART) in Drosophila melanogaster. To study these effects, larvae descendants of both crosses (ST and HB) were chronically treated with five concentrations of simvastatin, separately and in association with DXR. The results revealed no mutagenic/recombinogenic effect of simvastatin for any of the concentrations tested. A modulating effect of simvastatin was also observed on DNA damage induced by DXR. The reduction of total mutant frequency was observed for spots from descendants of both crosses, but the inhibition was more effective in descendants from the standard cross (ST). It is believed that this modulating effect is mainly associated with the antioxidant acti...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
