Although the pathogenesis of obesity in OZR is unknown, the association among hyperinsulinemia, insulin resistance, and hyperlipidemia suggests that investigations using OZR may help define how a number of vascular disease risk factors interact to cause end-organ damage. Like other rat strains, OZR do not develop atherosclerosis spontaneously. Nevertheless, in an endothelial injury model, atherosclerosis was worse in OZR than in LZR. Perhaps more intriguing is the fact that OZR develop spontaneous glomerular injury. Although the mechanisms important in the development and progression of glomerular injury in OZR remain to be clarified, both lipid abnormalities and glomerular hemodynamic alterations could play a role.
