1 Sequential phospholipase C-mediated hydrolysis of the polyphosphoinositides and phosphatidylinositol in cultured vascular smooth muscle cells stimulated with angiotensin II results in a coordinated series of biochemical events: a transient formation of inositol trisphosphate associated with calcium mobilization, and a biphasic, sustained formation of diacylglycerol associated with activation of protein kinase C and cytosolic alkalinization.

2 Formation of inositol trisphosphate and mobilization of calcium are attenuated by activation of protein kinase C. Sustained diacylglycerol formation is promoted by cytosolic alkalinization, and appears to require cellular processing of the angiotensin II-receptor complex. Diglycerides angiotensinogen Homo sapiens
