Professional Bio
Sergey Dikalov, PhD, is a Research Professor of Medicine in the Department of Medicine at Vanderbilt University Medical Center (VUMC).
He previously directed the Free Radicals in Medicine Core lab at Emory University and became an expert in the studies of vascular oxidative stress such as NADPH oxidases, uncoupled endothelial NO synthase, xanthine oxidase and mitochondria. He came to VUMC in 2011 as an associate professor and director of Free Radicals in Medicine Core, where he provided invaluable contribution to Vanderbilt clinical and basic science research projects.
Dr. Dikalov is a fellow of the American Heart Association (AHA) and serves on AHA committees. He has been an invited speaker locally and nationally at academic institutions and scientific meetings. He has authored over 156 original publications, including 46 as first author. These have appeared in high impact journals in cardiovascular sciences such as Journal of Clinical Investigation, Circulation Research, Hypertension, and Journal of Biological Chemistry.
His major accomplishments include discovery that essential hypertension is linked to mitochondrial dysfunction, overproduction of mitochondrial superoxide and formation of highly reactive oxidative stress products isolevuglandins. He developed mitochondria-targeted superoxide scavenger mitoTEMPO and mitochondrial scavenger of isolevuglandins mito2HOBA which improve mitochondrial function, reduce vascular dysfunction, and diminish hypertension. His work demonstrated pathogenic role of mitochondrial isolevuglandins including Sirt3 inactivation and promoting mitochondrial dysfunction. He demonstrated that mitochondrial cyclophilin D (CypD) has a previously unidentified role in vascular dysfunction and hypertension and supported the therapeutic potential of targeting CypD in this disease.
Dr. Dikalov directs the Free Radicals in Medicine Core function and training of graduate students and medical fellows in measurements of oxidative stress using state-of-art methods such as Electron Spin Resonance and HPLC providing indispensable support for oxidative stress studies at Vanderbilt.
