Copper Trafficking Within The Mitochondrion How Copper Enters Consequently, the efficient transport of cu into the mitochondria of cancer cells in vivo presents a bottleneck for harnessing cuproptosis as an effective anticancer treatment. we hypothesized that nanoparticles may provide a potential solution to selective delivery of cu into the mitochondria of cancer cells for triggering cuproptosis. Using copper ionophores to translocate extracellular copper into mitochondria is a clinically validated anticancer strategy that has been identified as a new type of regulated cell death termed “cuproptosis.” this study reports a mitochondria targeting cu(i) complex, cu(i)br(pph3)3 (cbp), consisting of a cuprous ion coordinated by three triphenylphosphine moieties and a br atom. cbp.
Simplified Model Of Intracellular Copper Regulation Here Cu Ext Abstract. mitochondria serve as sites for energy production and are essential for regulating various forms of cell death induced by metal metabolism, targeted anticancer drugs, radiotherapy and immunotherapy. cuproptosis is an autonomous form of cell death that depends on copper (cu) and mitochondrial metabolism. Abstract. mitochondria accumulate copper in their matrix for the eventual maturation of the cuproenzymes cytochrome c oxidase and superoxide dismutase. transport into the matrix is achieved by mitochondrial carrier family (mcf) proteins. the major copper transporting mcf described to date in yeast is pic2, which imports the metal ion into the. Copper in the mitochondria. to maintain cu homeostasis within a narrow range, cu uptake, distribution and excretion are strictly regulated [28]. in adults, cu content accounts for 1.4 × 10 −4 % of body weight which is approximately equal to 80 110 mg with most being located in skeletal muscle while only a small portion is found in the liver. The loading of copper (cu) into cytochrome c oxidase (cox) in mitochondria is essential for energy production in cells. extensive studies have been performed with mitochondrial cuproenzymes, such as sco1, sco2 and cox17, which contributes to the metallation of the oxidase. however, limited information is available on the upstream mechanism of cu transport and delivery to mitochondria.

However, limited information is available on the upstream mechanism of cu transport and delivery to mitochondria, especially through cu impermeable membranes, in mammalian cells. the mitochondrial phosphate transporter slc25a3, also known as pic2, binds cu and transports the ion through these membranes in eukaryotic cells, ultimately aiding. Mitochondria have other functions that help maintain healthy brain function — or cause problems when they go awry. for example, mitochondria help control the balance of potentially toxic.
