Abstract/OtherAbstract:
Evidence for pre-receptor, receptor and post-receptor glucagon defects was investigated in adipocytes from cortisol-treated rats. A decrease in glucagon binding due to a decreased number of receptors was observed. No changes in receptor affinity were detected. Both, the lipolytic response of glucagon and the ability of glucagon to increase basal and theophylline-stimulated cAMP accumulation remained unaltered. Moreover, a hyperglucagonemia accompanied by an increase in glucagon degradation in the serum of cortisol-treated rats was observed. Such alterations could represent a new mechanism by which glucocorticoids exert their biological actions.
