Balaraman (Raman) Kalyanaraman, PhD
Balaraman (Raman) Kalyanaraman, PhD, is the Chairman and Professor in the Department of Biophysics. He is the Harry R. & Angeline E. Quadracci Professor in Parkinson’s Research at the Medical College of Wisconsin.
His research interests are centered on the application of EPR in free radical biology and understanding the role of free radicals in signal transduction and apoptosis. His specific research areas are outlined below. He has served as an Associate Editor for Free Radical Research and the Biochemical Journal, and currently is Associate Editor for Free Radicals in Biology and Medicine.
Chemistry and Biophysics
Detection of free radicals by EPR spin-trapping, fluorescence, optical stopped-flow, and HPLC techniques
Syntheses of mitochondrially targeted spin traps, spin labels, and ROS-specific fluorescence probes
EPR/ENDOR/NMR studies of active site geometry of redox-active enzymes (e.g., superoxide dismutase)
Nitration of tyrosine- and tryptophan-containing peptides and protein (e.g., synucleins) in biological membranes
Mechanism of Signal Transduction/Cell Signaling
Nitric oxide and cyclic nucleotide-dependent cell signaling and proteasomal activation
Oxidant-induced iron signaling and apoptosis
Chemotherapeutic drug toxicity and prevention (e.g., doxorubicin); mechanism of apoptosis in tumor cells and normal cells
Mechanism of Disease
Role of mitochondria-derived oxidants in chemically induced Parkinsonism (e.g., MPTP, rotenone) in cell culture and animal models; mechanism of protein aggregation, proteosomal dysfunction, and apoptotic neuronal cell death
Oxidative stress and apoptosis induced by amyotrophic lateral sclerosis (Lou Gehrig's disease)/SOD1 mutants in cell culture and animal models; therapeutic intervention of disease progression in a G93A-transgenic animal model
