title: Hormone-sensitive adenylate cyclase in human colonic mucosa.
abstract: Human colonic adenylate cyclase has been shown to be sensitive to vasoactive intestinal polypeptide (VIP) and prostaglandins of the E- and F-type. Maximal activation of enzyme activity averaged 200% for VIP and 300-350% for the E-prostaglandins. Both classes of hormones had an additive effect on enzyme activity indicating the existence of two distinct hormone-sensitive adenylate cyclases in human colonic mucosa.
