1. We established a new animal model of metabolic syndrome, SHRSP fatty (fa/fa) rats, by crossing stroke-prone spontaneously hypertensive rats of the Izumo strain (SHRSP/Izm) to Zucker fatty (ZF) (fa/fa) rats. 2. The SHRSP fatty (fa/fa) rats have a missense mutation of the leptin receptor gene and plasma leptin concentrations are augmented. The SHRSP fatty (fa/fa) rats develop obesity and hypertension simultaneously. 3. Plasma metabolic parameters, including glucose, insulin and total cholesterol and triglyceride levels, were markedly elevated in SHRSP fatty (fa/fa) rats compared with SHRSP/Izm rats. Plasma triglyceride concentrations in SHRSP fatty (fa/fa) rats were significantly elevated compared with those in ZF (fa/fa) rats. The weight of adipose tissues in SHRSP fatty (fa/fa) rats was greater than that of SHRSP/Izm rats. The phenotype of SHRSP fatty (fa/fa) rats is similar to that of human metabolic syndrome.
