In two recent manuscripts published in Nature,the cholesterol-synthesis pathway was identified as a master regulator of ferroptosis sensitivity and therefore as a novel therapeutic target.1,2 Ferroptosis does not only represent one way to eliminate cancer cells,but also contributes to acute organ damage in the kidney,heart,brain,and liver,and it kills tissues during the process of organ *** term“ferroptosis”should be defined as a cellular process of iron-catalyzed lipid peroxidation-mediated rupture of the plasma membrane.
