Many studies have found that in mouse models with ALI/ARDS, an increase in lipid peroxidation marker MDA levels and a significant decrease in antioxidant enzyme activities such as SOD, CAT, and GPx have been observed (Yeh et al., 2014; Dianat et al., 2018; Su et al., 2019). The gene discussed is CAT; the disease is acute respiratory distress syndrome.
