WebGPX1 (cellular GPx) is a cytosolic enzyme that is expressed in most cell types and is thought to be responsible for 95% of overall lung tissue GPX activity (Ho et al., 1997).GPX1-deficient mice develop normally but are more susceptible to lung inflammation by influenza infection or cigarette smoke exposure (Duong et al., 2010; Yatmaz et al., 2013). WebGlutathione peroxidase 1, also known as GPx1, is an enzyme that in humans is encoded by the GPX1 gene on chromosome 3. [5] This gene encodes a member of the glutathione peroxidase family. Glutathione peroxidase functions in the detoxification of hydrogen peroxide, and is one of the most important antioxidant enzymes in humans. [6]
