概要	We hypothesized that diabetes activates renin-angiotensin system (RAS) in the geniculate ganglion containing taste a!erent neurons and changes the taste preference for glucose and sucrose. Adult male nondiabetic rats received a daily intraperitoneal injection of streptozotocin (STZ) for 2 days. Blood glucose levels of the STZ rats employed in this study was higher than 500 mg/dl. Geniculate ganglion was collected from rats, total RNA was extracted from the geniculate ganglion, and cDNA was synthesized from the RNA template by reverse transcription. Expression levels of RAS-related genes were determined by real-time PCR. Expression levels of angiotensinogen and angiotensin converting enzyme genes were higher in the STZ rats than in nondiabetic rats suggesting alteration of the RAS-related gene expression increases in taste preference for glucose and sucrose.
