NQO1 (NAD(P)H Quinone Dehydrogenase 1): NQO1 is an enzyme that protects cells from oxidative stress by catalyzing the reduction of quinones to hydroquinones. This activity helps to prevent the formation of reactive oxygen species and maintains cellular redox homeostasis. Polymorphisms in NQO1 have been linked to an increased risk of various cancers and susceptibility to toxin-induced toxicities, emphasizing its role in cellular protection and detoxification....
