...Sorafenib induces ferroptosis in certain cancer cells such as hepatocellular carcinoma (HCC) cells.(14,15) Sorafenib-induced ferroptosis occurs independent from the oncogenic status of Ras, RAF, PIK3CA, and p53....

...In HCC cell lines, sorafenib was reported to induce a non-apoptotic form of cell death that was suppressed by lipophilic antioxidants [27, 28], indicating that sorafenib activates ferroptosis in HCC cell lines....

...Based on our observations showing the role of iron and oxidative stress, we formulated the hypothesis that sorafenib might induce a form of cell death related to ferroptosis.(20) To explore this possibility, we used two approaches relying on pharmacology and the use of RNA interference, and reported to specifically inhibit ferroptosis: (i) the application of the chemical inhibitor ferrostatin-1; (ii) a strategy of RNA interference directed against the protein Iron-Responsive Element Binding protein-2 (IREB2)....

...Bodipy-C11 is a redox sensitive probe that intercalates in cellular membranes and whose shift of fluorescence reflects lipid peroxidation.(19,20) Using these two probes, we noticed that sorafenib induces oxidative stress in Huh7 cells (Figs....

...Finally, experimental manipulation of the redox status of cancer cells has been proposed to increase their sensitivity to medical treatments, such as radiation therapy.(33,34) Such strategies might also be useful to increase the cytotoxic effect of sorafenib on HCC cells....

...Herein, we report that the cytotoxic effects induced by sorafenib on HCC cells are prevented by deferoxamine (DFX), a potent chemical chelator of iron.(13) Iron is an essential micronutrient with an implication in several physiological processes in normal and cancer cells....
