NAD(P)H Oxidase: Role in Cardiovascular Biology and Disease

TL;DR: Vascular NAD(P)H oxidases have been found to be essential in the physiological response of vascular cells, including growth, migration, and modification of the extracellular matrix and have been linked to hypertension and to pathological states associated with uncontrolled growth and inflammation, such as atherosclerosis.
Journal ArticleDOI

Angiotensin II stimulates NADH and NADPH oxidase activity in cultured vascular smooth muscle cells.

TL;DR: The ability of Ang II to stimulate superoxide anion formation is examined and the identity of the oxidases responsible for its production is investigated to suggest that Ang II specifically activates enzyme systems that promote superoxide generation and raise the possibility that these pathways function as second messengers for long-term responses, such as hypertrophy or hyperplasia.
Journal ArticleDOI

Angiotensin II-mediated hypertension in the rat increases vascular superoxide production via membrane NADH/NADPH oxidase activation. Contribution to alterations of vasomotor tone.

TL;DR: Forms of hypertension associated with elevated circulating levels of angiotensin II may have unique vascular effects not shared by other forms of hypertension because they increase vascular smooth muscle .O2- production via NADH/NADPH oxidase activation.
Journal ArticleDOI

Angiotensin II cell signaling: physiological and pathological effects in the cardiovascular system

TL;DR: This review focuses on the structure and function of AT(1) receptors and the major signaling mechanisms by which angiotensin influences cardiovascular physiology and pathology.
Journal ArticleDOI

Cell transformation by the superoxide-generating oxidase Mox1

TL;DR: The cloning of mox1 is described, which encodes a homologue of the catalytic subunit of the superoxide-generating NADPH oxidase of phagocytes, gp91phox, which is expressed in colon, prostate, uterus and vascular smooth muscle, but not in peripheral blood leukocytes.
