For example, iron generates hydroxyl radicals via the Haber-Weiss reaction and the Fenton reaction, which promote ROS formation, and acute myeloid leukemia (AML) cells induce ferroptosis in AML cells by increasing ROS levels via the HMGB1-regulated RAS-JNK/p38 signaling pathway [149]. This evidence concerns the gene MAPK8 and acute myeloid leukemia.
