Fig. 3From: Iron and copper: critical executioners of ferroptosis, cuproptosis and other forms of cell deathProcess of cuproptosis. Copper induces cuproptosis through copper accumulation and the TCA cycle, and FDX1 promotes lipoylation of DLAT. Excessive copper led to loss of Fe-S cluster proteins under the regulation of FDX1. The red arrow indicates Cu, and the blue arrow indicates FeBack to article page
