Abstract

Ubiquitous free radical (Reactive Oxygen Species) production occurs continuously in our body from metabolic pathways and electron transport chain. Cigarette smoke, automobile exhaust, industrial effluents, etc., are polluting the environment with free radicals. Glutathione is the most abundant low molecular mass molecule that provides reducing equivalents to protect the cells against free radicals (oxidative stress). The activity of glutathione-dependent enzymes (Glutathione reductase, glutathione peroxidase, and glutathione – S – transferase) was estimated in 50 histopathologically proven breast cancer patients before and after surgery and compared with age-matched control. The activity of Glutathione related enzymes was found to be significantly increased in breast cancer patients when compared to control and mild decrease after surgery indicating prognosis after treatment.
