Oxidative stress in atherogenesis and arterial thrombosis: the disconnect between cellular studies and clinical outcomes.
Madamanchi NR, Hakim ZS, Runge MS. Madamanchi NR, et al. J Thromb Haemost. 2005 Feb;3(2):254-67. doi: 10.1111/j.1538-7836.2004.01085.x. J Thromb Haemost. 2005. PMID: 15670030 Free article. Review.
Various animal models of atherosclerosis support the notion that ROS released from NAD(P)H oxidases, xanthine oxidase, lipoxygenases, and enhanced ROS production from dysfunctional mitochondrial respiratory chain indeed have a causatory role in atherosclerosis

NADPH oxidase 4 regulates vascular inflammation in aging and atherosclerosis.
Lozhkin A, Vendrov AE, Pan H, Wickline SA, Madamanchi NR, Runge MS. Lozhkin A, et al. Among authors: madamanchi nr. J Mol Cell Cardiol. 2017 Jan;102:10-21. doi: 10.1016/j.yjmcc.2016.12.004. Epub 2016 Dec 14. J Mol Cell Cardiol. 2017. PMID: 27986445 Free PMC article.
We recently reported that increased NADPH oxidase 4 (NOX4) expression and activity during aging results in enhanced cellular and mitochondrial oxidative stress, vascular inflammation, dysfunction, and atherosclerosis. The goal of the present study was to eluc …

NOX4 NADPH Oxidase-Dependent Mitochondrial Oxidative Stress in Aging-Associated Cardiovascular Disease.
Vendrov AE, Vendrov KC, Smith A, Yuan J, Sumida A, Robidoux J, Runge MS, Madamanchi NR. Vendrov AE, et al. Among authors: madamanchi nr. Antioxid Redox Signal. 2015 Dec 20;23(18):1389-409. doi: 10.1089/ars.2014.6221. Epub 2015 Jul 14. Antioxid Redox Signal. 2015. PMID: 26054376 Free PMC article.
RESULTS: Both aged (16 months) Apoe(-/-) and Apoe(-/-)/p47phox(-/-) mice had increased atherosclerotic lesion area, aortic stiffness, and systolic dysfunction compared with young (4 months) cohorts. Cellular and mitochondrial ROS (mtROS) levels were significantly hi …
