WebMar 17, 2024 · Its finally out! copper induced cell death, or #cuproptosis, a new form of regulated cell death induced by copper ionophores targeting lipoylated (there is such a thing) and Fe-S cluster proteins in a process that is FDX1 dependent . @broadinstitute. science.org. Copper induces cell death by targeting lipoylated TCA cycle proteins. WebHere, we show in human cells that copper-dependent, regulated cell death is distinct from known death mechanisms and is dependent on mitochondrial respiration. We show that copper-dependent death occurs by means of direct binding of copper to lipoylated components of the tricarboxylic acid (TCA) cycle. This results in lipoylated protein ...
