Stimulation of glycogenolysis in hepatocytes by angiotensin II may involve both calcium release and calcium influx. 1983

L M DeWitt, and J W Putney

The stimulation of [3H]glucose release (a measure of glycogenolysis) from isolated guinea pig hepatocytes by Ca-mobilizing agonists can be resolved into two phases. The initial transient phase is independent of extracellular Ca, and is probably a result of Ca released from an intracellular pool. The second phase occurs only in the presence of extracellular Ca, which suggests that Ca-influx is also involved in the mechanism of Ca-mobilization by these agents in the guinea pig hepatocyte.

D007700 Kinetics The rate dynamics in chemical or physical systems.
D008099 Liver A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances. Livers
D008112 Liver Glycogen Glycogen stored in the liver. (Dorland, 28th ed) Hepatic Glycogen,Glycogen, Hepatic,Glycogen, Liver
D002118 Calcium A basic element found in nearly all tissues. It is a member of the alkaline earth family of metals with the atomic symbol Ca, atomic number 20, and atomic weight 40. Calcium is the most abundant mineral in the body and combines with phosphorus to form calcium phosphate in the bones and teeth. It is essential for the normal functioning of nerves and muscles and plays a role in blood coagulation (as factor IV) and in many enzymatic processes.

D000804 Angiotensin II An octapeptide that is a potent but labile vasoconstrictor. It is produced from angiotensin I after the removal of two amino acids at the C-terminal by ANGIOTENSIN CONVERTING ENZYME. The amino acid in position 5 varies in different species. To block VASOCONSTRICTION and HYPERTENSION effect of angiotensin II, patients are often treated with ACE INHIBITORS or with ANGIOTENSIN II TYPE 1 RECEPTOR BLOCKERS.
