Another study also shows that Erastin combined with cisplatin can increase the expression of ACSL4 and cyclooxygenase‐2 (COX‐2) and decrease the expression of GPX4 and FTH1 in HEY cells and ovarian cancer tissues, thus promoting ferroptosis in HEY cells and inhibiting tumor growth [131]. Here, GPX4 is linked to ovarian carcinoma.
