Redox pioneer: professor Irwin Fridovich.

Research output: Contribution to journalArticlepeer-review


Dr. Irwin Fridovich (Ph.D., 1955) is recognized here as a Redox Pioneer because as first/last author he has published at least 1 paper on antioxidant/redox biology that has been cited over 1000 times and has published at least 10 papers each cited over 100 times. In collaboration with his graduate student, Joe McCord, Dr. Fridovich discovered the activity of superoxide dismutase (SOD). Subsequently, he and his colleagues demonstrated that the enzyme is ubiquitous among aerobic biota and comprises a critical defense against oxidative stress. With coworkers, Dr. Fridovich identified the first physiological targets of superoxide, the iron-sulfur clusters of dehydratases. They also showed that SOD is just one of several strategies by which cells fend off oxidative stress. It is now clear that organisms are chronically exposed to endogenous superoxide; further, microbes, plants, and mammals all employ superoxide as a weapon to poison their competitors. Thus, the achievement of Fridovich's laboratory was not only the seminal discovery of SOD but also the painstaking work over the subsequent decades that illuminated its place in biology.
