During ferroptosis, a polyunsaturated fatty acid \u2014 a type of lipid found in the cell membrane \u2014 undergoes a modification called peroxidation, which causes an increase in the level of molecules termed reactive oxygen species.

Cysteine provides a building block for the production of glutathione, a molecule involved in a pathway that can combat ferroptosis.<\/p>\n<p>The drug sorafenib is approved for clinical use. It can induce ferroptosis by inhibiting SLC7A11. The authors demonstrate that sorafenib treatment of cultured human mesothelioma cells that have mutations in the gene encoding merlin causes the cells to undergo ferroptosis.
