Regulation of glycogen phosphorylase activity in fat body of Locusta migratoria and Periplaneta americana.

Abstract：

:Saline extracts of the corpus cardiacum (CC) of Locusta migratoria activate glycogen phosphorylase in locust fat body. The response of phosphorylase to CC extracts and to synthetic adipokinetic hormone (AKH) suggests that the factor responsible for the activating effect of the CC on phosphorylase is AKH, supplemented to a minor degree with Compound II. Octopamine does not influence fat body phosphorylase activity in locusts, however, it elicits a rapid short-term hyperlipemia. In cockroaches, Periplaneta americana, injection of octopamine results in a strong activation of fat body phosphorylase within 1 min. Cockroach CC extract exerts a more prolonged effect on phosphorylase activity than does octopamine.
