The decreased growth of ovarian cancer cells caused by PRDX6 KO was mainly attributed to impaired proliferation abilities as evidenced by 5‐ethynyl‐2′‐deoxyuridine (EdU) assay (Figure 1F), but not induction of apoptosis (Figure S2A,B, Supporting Information). The gene discussed is PRDX6; the disease is ovarian carcinoma.
