It has also been found that there are six ferroptosis‐related hub genes (driver genes DNAJB6, BACH1, and ALOX12, suppressor genes RB1, and marker genes SELENOS and STEAP3) in ovarian cancer, which have been confirmed to be closely related to the disease progression and prognosis of ovarian cancer patients [134]. The gene discussed is SELENOS; the disease is ovarian cancer.
