Importantly, it was observed that IF peptide induced the expressions of levels of some antioxidant proteins in the kidney, such as glutathione peroxidase 4, heme oxygenase 1, superoxide dismutase 1, superoxide dismutase 2, and peroxiredoxin 2 (PRDX2), to a greater extent compared to captopril, a medication commonly used in the management of hypertension (Tsai et al. 2020). The gene discussed is PRDX2; the disease is hypertensive disorder.
