DHA was also described to influence the antioxidant capacity of cancer cells, as described by Merendino and collaborators, that showed that DHA leads to active glutathione (GSH) extrusion in a pancreatic cancer cell line [60], and by Ding and Lind, that discovered that DHA treatment of many ovarian cancer cell lines coped with diminished glutathione peroxidase-4 (GPx-4) protein expression [61]. The gene discussed is GPX4; the disease is cancer.
