Abstract
Statins is an inhibitor in the cholesterol biosynthesis pathway. Simvastatin (SIM) has been found to have other clinical benefits besides those resulted from its actions of reducing plasma level of low density lipoprotein (LDL) cholesterol. Both mevastatin (MEV) and parvastatin (PAR) can increase release of nitric oxide (NO) which is a potent inhibitor of platelet aggregation and endothelial cell conglutination. In this study, we found different concentrations of SIM had different effects on 3-hydroxy-3-methylglutaryl-CoA reductase (HMGR) mRNA expression and NO and total cholesterol (TC) in normal cultural pig kidney cells. NO and TC were measured by using colorimetry in 550 nm and 546 nm, respectively. HMGR mRNA expression was tested by RT-PCR. Results showed that HMGR mRNA expression had a significant difference (P < 0.05) between different concentration of SIM treatment (0, 5, 10, or 25 μmol/l). HMGR mRNA expression and TC content decreased gradually with the elevation of SIM concentration. The content of NO increased with the elevation of SIM concentration, but the difference was not notable. SIM affects the expression of HMGR-CoA, TC and NO in normal cells, but the specific mechanism need to be further research.
