title: Angiotensin II stimulates phosphatidylinositol turnover in adrenal glomerulosa cells by a calcium-independent mechanism.
abstract: Angiotensin II enhances phosphatidylinositol turnover in isolated adrenal glomerulosa cells. In the present experiments we examined whether this effect required the presence of extracellular Ca2+. It was found that neither the stimulation of phosphatidylinositol breakdown nor the stimulation of incorporation of [32P]phosphate into phosphatidic acid and phosphatidylinositol required the presence of extracellular Ca2+. These observations suggest that the enhancement of phosphatidylinositol turnover may precede, but does not depend on, angiotensin-induced Ca2+ influx.
