in cultured rat aortic smooth muscle cells , the ang ii-induced signaling sequence is biphasic with rapid hydrolysis of the polyphosphoinositides producing an early ( 15 s ) diacylglycerol ( dg ) peak and a transient rise in inositol trisphosphate ( ip3 ) and more delayed phosphatidylinositol ( pi ) hydrolysis resulting in sustained dg formation ( peak at 5 min ) .
