Responses to oxidative stress are generally regulated by redox-responsive transcription factors (TFs). The
abrupt variation in the partial pressure of oxygen (pO2) constitutes a regulatory mechanism. Such TFs forming an integral
part of those putative pathways are hypoxia-inducible factor-1α(HIF)-1αand nuclear factor-κB (NF-κB), both are sufficiently
tuned to govern such a specific response. Reactive species are produced during this transition and the antioxidant
defense system controls their production. Oxidative stress occurs when there is imbalance between the production and removal
of reactive species. Evidence exists showing that enhancement of the antioxidant defense system can reduce markers
of oxidative stress. Recognition of reactive species and redox-mediated modifications as signals may open up a field of
cell regulation via targeted control of TFs and hence can providea novel way of controlling diseases. This synopsis summates
the major cutting-edge research work in the field of oxidative stress, and surgically identifies common and unique
pathways involved with oxidative stress as means of regulatory elements governing TFs.
