FADS2 and clear cell adenocarcinoma: In ovarian cancer, iron overload promotes metastasis, while p53, lipid-modifying enzymes (SCD1/FADS2), and the tumor microenvironment (e.g., CXCL8/CXCR2 axis) modulate ferroptosis sensitivity, providing avenues to target aggressive subtypes such as clear cell carcinoma.
