title: Role of cyclic AMP in steroid action in rat intestine.
abstract: We have investigated the effect of mineralocorticoids on intestinal fluid and electrogenic glucose-linked Na+ transport across isolated sections of the rat small intestine. A rapid in vitro response is observed that contrast with the delay normally associated with steroid hormone responses. Cyclic AMP is known to affect intestinal glucose, water and Na+ transport and the effects of the steroids may be understood in terms of an inhibitory effect on intestinal cyclic AMP production. An inhibitory effect of the steroids on membrane-bound adenylate cyclase has been demonstrated and dose-response effects suggest the presence of specific membrane-bound glucocorticoid receptors.
