Mechanisms
Simvastatin lowers HMGR but not CETP expression in bovine adipocytes (Anim Biotechnol 2020)
Original title: Effect of simvastatin on bovine intramuscular and subcutaneous adipocytes proliferation and gene expression in vitro
Bovine intramuscular and subcutaneous adipocytes from Luxi Yellow cattle were treated with different concentrations of simvastatin in vitro to measure mRNA expression of HMG-CoA reductase, CETP, and lipoprotein lipase. Simvastatin showed dose-dependent toxicity on the adipocytes without affecting cell proliferation, and decreased HMG-CoA reductase expression in a dose-dependent manner, but had no significant effect on CETP or lipoprotein lipase expression. The authors conclude simvastatin may lower cholesterol content by reducing HMG-CoA reductase rather than by acting on CETP or lipoprotein lipase, which appear regulated through other mechanisms.
Original abstract
Simvastatin (SIM) is a widely used anticholesterolemic drug that blocks the biosynthesis of cholesterol. However, SIM also has pleiotropic effects on 3-hydroxy-3-methyglutary-CoA reductase (HMGR), cholesteryl ester transfer protein (CETP), and lipoprotein lipase (LPL), which are important genes in the cholesterol biosynthesis and transport processes. We investigated the effects of different concentrations of SIM on the mRNA expression of these genes in bovine intramuscular and subcutaneous adipocytes from the longissimus dorsi muscle and subcutaneous fat tissues of Luxi Yellow cattle. The results showed that SIM treatment showed dose-dependent toxicity on normal adipose cells, but no effect on cell proliferation. SIM decreased HMGR expression in a dose-dependent manner but showed no significant effect on CETP and LPL expression. Thus, SIM may lower the cholesterol content by decreasing the HMGR expression level, but CETP and LPL may be regulated through other mechanisms, which require further investigation.
