环磷酸腺苷(cAMP)是多种激素和神经介质发挥细胞内作用的第二信使,在环磷酸腺苷的研究中,其酶系统越来越受到人们的重视。腺苷环化酶(Adenylate Cyclase,简称AC),是激素通过cAMP调节细胞功能的关键环节之一,激素与靶细胞受体发生作用,使AC活性改变,从而使cAMP增加或减少。因此,AC活性的测定,对于cAMP调节细胞代谢和其它功能活动机制的研究,对于进一步阐明激素作用原理,提供了一个重要手段。这一测定 Cyclic cAMP (AMPA) is the second messenger of intracellular effects of many hormones and neurotransmitters. In the study of cyclic AMP, its enzymatic system is getting more and more attention. Adenylyl cyclase (AC) is one of the key processes in which hormones regulate cellular function through cAMP. Hormones interact with target cell receptors to change AC activity, thereby increasing or decreasing cAMP. Therefore, the determination of AC activity, cAMP regulation of cell metabolism and other functional mechanisms of action, to further clarify the role of hormones, provides an important means. This determination
