We also conducted further analysis via KM plotter database and demonstrated that high levels of PRDX3, PRDX5, and PRDX6 predicted an unsatisfactory prognosis in ovarian cancer, and PRDX3 predicted a poor clinical outcome particularly in poor differentiation and late-stage serous ovarian cancer patients. This evidence concerns the gene PRDX3 and ovarian serous adenocarcinoma.
