General description

Anti-oxidant defense is known to be regulated by various mechanisms including the usage of nuclear factor erythroid 2-related factor 2 (Nrf2). Under normal physiological conditions, Nrf2 is bound to Kelch-like ECH-associated protein 1 (Keap1), a cytoplasmic repressor. Keap1 also acts as a substrate adaptor for Cullin3-dependent ubiquitin ligase and also targets Nrf2 for degradation by proteosomes. The substrate adaptor function of Keap1 is inactivated during physiological stress. In this respective condition, a range of oxidative and electrophilic stimuli such as ROS, diethyl malonate, and certain disease processes, resulting from Nrf2 accumulation, enters the nucleus and thereby activates the expression of select anti-oxidant genes. Such genes promote the detoxification of ROS and other harmful molecules, which contribute to the carcinogenesis.

Oxidative stress plays a critical role in the pathogenesis of intestinal ischemia reperfusion (IIR) injury. Enhancement in endogenous Lipoxin A4 (LXA4), a potent antioxidant and mediator, is associated with attenuation of IIR. However, the effects of LXA4 on IIR injury

Bronchopulmonary dysplasia (BPD) is caused primarily by oxidative stress and inflammation. To induce BPD, neonatal rat pups were raised in hyperoxic (>90% O2) environments from day one (P1) until day ten (P10) and treated with N-acetyl-lysyltyrosylcysteine amide (KYC). In vivo

Compared with the in vivo environment, porcine in vitro embryo-culture systems are suboptimal, as they induce oxidative stress via the accumulation of reactive oxygen species (ROS). High ROS levels during early embryonic development cause negative effects, such as apoptosis. In
