Abstract

Role of muscarinic receptor in the regulation of glucose uptake or lipolysis in adipose tissue remained unclear. In epididymal white adipose tissue (WAT) isolated from Wistar rats, we observed that acetylcholine (ACh) attenuated the insulin-stimulated glucose uptake and the release of glycerol from WAT in a concentration-dependent manner. Using the blockade of specific antagonists, both actions of ACh were characterized mainly due to an activation of M3 receptors. In the presence of various inhibitors for PLC-PKC pathway, ACh-decreased glucose uptake was also reversed. Taken together, these results suggest that muscarinic M3 receptor is involved in the regulation of glucose uptake and/or lipolysis in adipose tissue.
