FER and glioma: Moreover, lipid peroxidation inhibitors ferrostatin-1 (Fer-1) and liproxstatin-1 (Lip-1) also inhibited DHA-induced ROS, lipid ROS and MDA generation as well as ferroptosis in both glioma cell lines (Additional file 1: Figure S3B, S4 and S2G), verifying the pro-ferroptotic effects of DHA.
