Abstract:
:Glycogen phosphorylase in PC12 cells exists in two forms analogous to those found in brain and muscle. The active phosphorylated form of the enzyme, phosphorylase-a, represents about 20-30% of total glycogen phosphorylase in these cells. Incubation of PC12 cells with 100 ng 7S nerve growth factor/ml increased phosphorylase-a within minutes. In contrast to nerve growth factor, insulin (6 ng/ml) and epidermal growth factor (6 ng/ml) decreased phosphorylase-a. Activation of phosphorylase-a by nerve growth factor was not accompanied by increases in cyclic AMP; however, removal of extracellular Ca2+ or incubation of cells with calcium channel blockers inhibited activation of glycogen phosphorylase by nerve growth factor.
