摘要：
Treatment of intact adipocytes with the autoregulatory PKC pseudosubstrate PKC(19-31) inhibited insulin-stimulated hexose uptake and lipogenesis, with no effect on basal values. The effect was dose-dependent with respective IC50 values of 30-mu-M and 600-mu-M for insulin-stimulated hexose uptake in electroporated and intact adipocytes. These studies indicate that PKC may play a role in the mediation of insulin action in adipocytes.
