Abstract

Insulin (10 and 100 nM) and phorbol esters increased the phosphorylation of several proteins, including 40, 47 and 80 kDa proteins, which are markers for protein kinase C activation. Insulin effects were evident at 2 min and increased over 20 min. These findings suggest that insulin activates protein kinase C in BC3H-1 myocytes.
