Abstract
Aspartoacylase (ASPA) hydrolyzes N-acetylaspartic acid (NAA) into aspartate and acetate. Normal hydrolysis of NAA is important to maintain healthy neurons. Since enteric neuropathy is one of the events seen in diabetes, whether ASPA activity is affected in diabetic condition is not known. In order to investigate the possibility, ASPA activity was examined in the duodenum and brain of obesity induced diabetes model mouse. Aspartoacylase activity was high in the diabetic mouse duodenum compared to control duodenum. The same result was also observed by immunostaining of the mouse duodenum. The activity of ASPA was found to be elevated in the brain of diabetic mouse compared to the control brain. These data suggest that normal hydrolysis of NAA is affected by ASPA activity seen in the type 2 diabetes model mouse and this change is likely to contribute to neuropathy seen in diabetes, if documented also in patients with type 2 diabetes.Entities:
