| Research Abstract |
Two distinct types of angiotensin II (AngII) receptors, AT_1 and AT_2, have been cloned. We have previously shown that stimulation of AT_2 reduces intracellular cGMP levels in cultured porcine chromaffin cells in which AT_2 is the predominantly expressed receptor. However, it has not been determined whether AT_1 or AT_2 affects signal transduction pathways in chromaffin cells. Using Genetic Micro System(GMS-418-array scanner), we compare the effects of AngII plus CV-11974 (an AT_1 antagonist, which simulates specific AT_2 stimulation) with AngII plus PD 123319 (an AT_2 antagonist, which simulates specific AT_1 stimulation). There are several genes down and over expressed under such condition. We are characterize these genes.
