Independent Variation of Glucagon and Epinephrine Responsive Components of Hepatic Adenyl Cyclase as a Function of Age, Sex and Steroid Hormones

Abstract

This study presents data which indicate that the activities of the glucagon and epinephrine responsive components of hepatic adenyl cyclase vary separately as a function of age, sex and steroid hormone levels in the rat. These observations lend support to the hypothesis that the 2 hormonally sensitive adenyl cyclase systems in liver are independent. (Endocrinology86: 154, 1970)
