RESEARCH SUMMARY

Dr. Ridnour received her Ph.D. under the auspices of the late Dr. Larry Oberley where her work demonstrated that the tumor suppressive effects of MnSOD are mediated, at least in part, by an imbalance in peroxide generating versus peroxide metabolizing enzymes. She completed her postdoctoral training at Washington University in the laboratory of Dr. Douglas Spitz, where she identified thiol-dependent mechanisms associated with NO-induced resistance to peroxide stress. Dr. Ridnour joined the research group of Dr. David Wink (NCI) in 2003. Her research interests include nitric oxide (NO) regulation of extracellular matrix during cancer progression.
