title: Comparative effects of pravastatin-induced DNA synthesis on serum-stimulated synchronized and proliferative rat mesangial cells.
abstract: To compare the effects of pravastatin, a 3-hydroxy-3-methylglutaryl-Coenzyme A (HMG-CoA) reductase inhibitor, on DNA synthesis in synchronized and proliferative rat glomerular mesangial cells (MCs), growth-arrested and proliferative MCs were exposed to medium containing 20% or 10% FBS, respectively, to induce mitogenesis. Different doses of pravastatin (10(-3)-10(-9) M) were added for 48 h. DNA synthesis was assessed by Bromodeoxyuridine (BrdU) incorporation. Pravastatin caused a significant (P < 0.05) dose-dependent reduction in BrdU incorporation in both serum-stimulated synchronized and proliferative MCs, but higher doses are required in the latter.
