Abstract:
BACKGROUND: Nitric oxide (NO) can influence glucose transportation. Although its signal transmission pathway is not certain, it has been confirmed that the pathway is different from insulin. OBJECTIVE: To explore NO signal transmission pathway and the regulatory mechanism for the glucose uptake of skeletal muscle during exercise. RETRIEVAL STRATEGY: Using the keywords of "nitric oxide, signal, glucose", we searched the Pubmed database for the relevant articles about the transmission pathway and its regulation of glucose uptake in skeletal muscle published from January 1996 to November 2007. Meanwhile, the related foreign language books were retrieved manually from national library. Articles about the regulation of NO to muscular blood flow, signal transmission and glucose under exercise stress in human and gnawer were selected. Pathologically related basic studies were excluded. LITERATURE EVALUATION: Sixty related literatures (books) were collected, and 30 were accorded with the inclusive criteria, of which 5 were review articles, 23 were basic researches and 2 were related books. Meanwhile, 20 articles were related to the effects of NO on blood flow regulation and vasodilation, 4 articles and 2 books were related to signal transduction and 4 were about its signaling effect during exercise. DATA SYNTHESIS: NO is a signal molecule. It can mediate various biological phenomenon and displays strong vasodilation effect. The production of NO is increased in vivo during exercise, and NO can stimulate glucose uptake in skeletal muscle through its transduction. CONCLUSION: The generation of NO during exercise has positive effect on glucose uptake in skeletal muscle. The contraction and glucose uptake are closely correlated to the generation and transmission of NO, but the mechanism is still unclear.
