Pravastatin is a potent inhibitor of HMG-CoA reductase and is effective in lowering serum lipid levels. Recent studies have shown that pravastatin also reduces oxidative modification of LDL and decreases albuminuria in patients with diabetes. To determine the possible benefit of pravastatin on the diabetic kidney, we have measured the effects of pravastatin on the proliferation and the production of superoxide and fibronectin, and the expression of fibronectin mRNA of glomerular mesangial cells stimulated by oxidized-LDL and high glucose. Our results demonstrated that the [(3)H]-labeled thymidine uptake of mesangial cells decreased after oxidized-LDL stimulation (50 microg/ml, 6 h) and increased after high glucose stimulation (25 mM, 48 h). The production of superoxide and fibronectin and the expression of fibronectin mRNA of glomerular mesangial cells were all significantly increased after stimulation with either oxidized-LDL or high glucose, or the combination of oxidized-LDL and high glucose. Pravastatin (100 microM, 48 h) alone had no effect on unstimulated cells. However, pravastatin significantly reversed thymidine uptake, inhibited the production of superoxide and fibronectin, and inhibited the expression of fibronectin mRNA of glomerular mesangial cells after stimulation with either oxidized-LDL or high glucose. Our results indicate that pravastatin may effect as an antioxidant and may suppress fibronectin synthesis of glomerular mesangial cells in diabetic patients with hyperlipidemia.
