title: Antiproliferative effect of fluvastatin and thiazolidinedione in mesangial cells of diabetic rats.
abstract: Treatment with hydroxymethylglutaryl coenzyme A reductase inhibitors and thiazolidinedione derivatives may prevent the development of diabetic nephropathy. The precise mechanisms of the beneficial effects of these agents in mesangial cells are uncertain. We cultured mesangial cells from Otsuka Long-Evans Tokushima Fatty (OLETF) rats, a model for human type 2 diabetes mellitus. The effects of fluvastatin and/or troglitazone on DNA synthesis were determined. Fluvastatin in combination with troglitazone markedly inhibited DNA synthesis and induced apoptosis in mesangial cells from OLETF rats. Combined therapy with fluvastatin and thiazolidinedione derivatives may be effective for suppression of mesangial cell proliferation in the early phase of diabetes, thereby possibly slowing the evolution of diabetic glomerulopathy.
