Abstract:
:Insulin alone at concentrations of less than 1 to 5 uU/ml increased the enzyme activities of glycogen synthase, synthase phosphatase, phosphorylase, and phosphorylase phosphatase in hepatoma H4 cells in culture in the presence and absence of serum. Increase in total and active forms of glycogen synthase and phosphorylase were observed. Cycloheximide blocked the action of insulin on glycogen synthase, glycogen synthase phosphatase and phosphorylase phosphatase. The enzymes with the exception of glycogen synthase phosphatase were expressed with greater hormonal sensitivity in the absence as compared to the presence of serum in terms of hormone concentration required and or time of onset. These results demonstrate that these glycogen metabolizing enzymes are under long term control by insulin, with glycogen synthase being the most sensitive of the enzymes studied to the action of the hormone.
