Abstract:
ObjectiveTo investigate the effect of Simvastatin on LOX-1 and ROS in NRK52E induced by ox-LDL.MethodsNRK-52E cells were divided into three groups: Control group,ox-LDL group (50 μg/ml ox-LDL) and Simvastatin group (10 μmol/L Simvastatin +50 μg/ml ox-LDL).After incubation for 24 h,the expression of LOX-I was analyzed by Western blotting,and production of reactive oxygen species (ROS) was analyzed with confocal laser scanning microscopy.ResultsNRK-52E expressed LOX-1 at low level,50 μg/ml ox-LDL increased the expression of LOX-1 by 6.80 times.Pre - treatment with Simvastatin decreased LOX-1 expression by 65％.There was little ROS generation in NRK52E cells,50μg/ml ox-LDL promoted the expression of LOX-1 by 4.86.times.Pre - treatment with Simvastatin decreased ROS generation by 60％.ConclusionsSimvastatin upregulate LOX-1 expression and ROS generation induced by Ox-LDL in NRK52E cells.
