A series of synthetic peptides corresponding to the amino-terminal sequence of human growth hormone (hGH) has been studied for insulin-potentiating effects using three different bioassay systems: (1) intravenous insulin tolerance tests, (2) insulin binding to specific receptors of hepatic plasma membranes and isolated hepatocytes, and (3) modulation of insulin-dependent glycogen synthase and glycogen phosphorylase in muscle and adipose tissue.

Insulin deficiency was not associated with greater changes in epinephrine-induced activation of glycogen phosphorylase kinase than that observed in normal hearts.

Whereas total cardiac glycogen phosphorylase activity appears to be unaffected by severe insulin deficiency, a diabetes-induced decreased in hepatic glycogen phosphorylase activity has been demonstrated by our laboratory and others using liver extracts, isolated perfused liver, and cultured hepatocytes.

Alloxan diabetes induced in white rats by intraperitoneal injection of alloxan-monohydrate (15 mg/100 g body weight) was used to study changes in the glycogen phosphorylase a and b, phosphoprotein phosphatases and hexokinase activities under insulin deficiency conditions.

Inositol phosphoglycan mimicked the action of insulin on both forms of the enzyme from adult hepatocytes, whereas in fetal cells insulin did not change, and purified inositol phosphoglycan reduced the activities of glycogen phosphorylase.

Castration elevated the blood glucose level, which was accompanied by inhibitory effect on serum insulin, Akt phosphorylation, GLUT4 expression and its plasma membrane population, glucose uptake, glycogen and glycogen synthase activity, and stimulatory effect on GLUT2 expression and glycogen phosphorylase activity in tissues studied.

Glycogen phosphorylase inhibitors that act in hepatocytes either exclusively by dephosphorylating GPa (e.g. indole carboxamides) or by allosteric inhibition of GPa (1,4-dideoxy-1,4-D-arabinitol) are very powerful experimental tools to determine the relative roles of covalent modification of glycogen phosphorylase and/or cycling between glycogen synthesis and degradation in the mechanism(s) by which insulin and neurotransmitters regulate hepatic glycogen metabolism.

Also, induced significantly higher activities of hepatic G6Pase and glycogen phosphorylase compared with controls, while give significant lowered serum insulin, C-peptide level and renal catalase activity.
