Staurosporine stimulates phospholipase D activation in human polymorphonuclear leukocytes.

Abstract

Treatment of 1-O-[3H]alkyl-2-acyl-phosphatidylcholine-prelabeled human polymorphonuclear leukocytes (PMNs) with staurosporine (50 nM to 1 microM) induced a time- and concentration-dependent generation of tritiated phosphatidic acid (PA), reaching approximately 225% of the control value at 15-20 min. In the presence of ethanol, staurosporine induced a… (More)
