T2DM was induced in rats fed a high-fat (HF)-diet followed by the intraperitoneal injection of low-dose streptozotocin (STZ, 35 mg/kg). Sixty male Sprague-Dawley rats were divided into 4 groups: the control, HF-4W (HF diet for 4 weeks), HF-8W (HF diet for 8 weeks) and the T2DM group. During the development of T2DM, the production of ghrelin in the stomach and leptin in adipose tissue, the blood levels of ghrelin and leptin, and the expression of leptin and ghrelin receptors (OB-Rb and GHS-R1a) in the hypothalamus were measured by enzyme-linked immunosorbent assay (ELISA), radioimmunology assay (RIA), immunohistochemistry (IHC) and real-time reverse transcription-polymerase chain reaction (real-time RT-PCR). IR was assessed using the hyperinsulinemic-euglycemic clamp technique. The production of ghrelin in the stomach, the plasma ghrelin levels and the expression of GHS-R1a in the hypothalamus were significantly reduced in the HF-4W and HF-8W rats compared with the control rats; however, no significant difference was found between the HF-8W and T2DM group rats. Comparing the control to the T2DM group, the production of leptin in the adipose tissue and the serum leptin levels increased, whereas the expression of OB-Rb in the hypothalamus decreased. At the same time, the glucose infusion rate (GIR), indicating the insulin sensitivity, decreased significantly; GIR positively correlated with plasma ghrelin and negatively correlated with serum leptin levels. In conclusion, increased leptin levels are associated with obesity and T2DM, while decreased ghrelin levels are associated with obesity/IR rather than T2DM."xsd:string |
