The mechanism by which the metabolic effects of insulin are transmitted is yet to be resolved. Second messengers mediating the action of insulin have been proposed and recently an insulin-dependent, peptide-like, heat- and acid-stable substance (Mr approx. 1000-3000) released from plasma membranes has been described which regulates the activity of key enzymes such as pyruvate dehydrogenase by altering its state of phosphorylation. It has been suggested that this material is the elusive second messenger of insulin and its discovery, generation, properties, isolation and mode of action are reviewed.
胰岛素代谢作用的传导机制尚待阐明。人们已经提出了介导胰岛素作用的第二信使,最近有报道称,从质膜释放出一种胰岛素依赖性、类似肽、耐热且耐酸的物质(分子量约为1000 - 3000),该物质通过改变丙酮酸脱氢酶等关键酶的磷酸化状态来调节其活性。有人认为这种物质就是难以捉摸的胰岛素第二信使,本文对其发现、生成、特性、分离及作用方式进行了综述。
