Cellular imbalance in the levels of antioxidants and reactive oxygen species (ROS) is directly associated with a number of pathological states and results in programmed cell death or apoptosis. We demonstrate the use of

Aerobic organisms experience oxidative stress due to generation of reactive oxygen species during normal aerobic metabolism. In addition, several chemicals also generate reactive oxygen species which induce oxidative stress. Thus oxidative stress constitutes a major threat to organisms living in aerobic environments. Programmed cell death or apoptosis is a physiological mechanism of cell death, that probably evolved with multicellularity, and is indispensable for normal growth and development.
