In fact, the water molecules get replaced one at a time, and so this is made up of a series of part-reactions: DiNicolantonio JJ, et al. (2018). Copper deficiency may be a leading cause of ischaemic heart disease. Copper is a vital component for your body, but you need just the right amount. Copper supplements may improve some health conditions, though these are usually associated with a copper deficiency. This second structure is known as a chelate from a Greek word meaning a crab's claw. You can picture the copper ion as being nipped by the claw of the 1,2-diaminoethane molecule. Fortunately, copper supplements can be a last resort when attempting to increase copper levels in the body. There are other measures one can take before turning to supplements, namely diet and copper infused water.

The article also noted that copper may play a role in the development of tumors, and that some types of cancer cells have elevated copper levels. Johnstone, C. N. et al. Functional and molecular characterisation of EO771.LMB tumours, a new C57BL/6-mouse-derived model of spontaneously metastatic mammary cancer. Dis. Models Mech. 8, 237–251 (2015). The School of Medicine and Tallaght University Hospital, Trinity Biomedical Sciences Institute, Trinity College Dublin, Dublin, Ireland Copper is an essential cofactor for a host of metalloenzymes/proteins including superoxide dismutase-1 (SOD1), vascular adhesion protein-1, MMP-9, lysyl oxidase, VEGF, and angiogenin 10, 11, 12 that contribute to carcinogenesis 11, 13, 14, 15. Copper was shown to be a necessary binding partner for MEK1/2-mediated BRAF signaling in melanoma progression 16, copper depletion was able to overcome resistance to BRAF and MEK1/2 inhibitors 17, and regulate autophagy in lung adenocarcinoma 18. In a model of colon cancer, inflammatory cytokines, such as IL-17 was shown to induce increased intracellular uptake of copper via increased expression of metalloreductase STEAP4, to promote tumorigenesis 19. A recent study also demonstrated that copper chelators mediate ubiquitin-dependent PD-L1 degradation via inhibition of STAT3 and EGFR phosphorylation 20. Copper chaperone, ATOX1, has been demonstrated as an important mediator of breast cancer metastasis, and therefore a potential biomarker for the effectiveness of copper depletion therapy 21. In the Her2/neu breast cancer transgenic mice, TM treatment was associated with improved disease-free survival 22. Our phase II clinical trial of TM (NCT00195091) 23, with 75 breast cancer patients at high risk for relapse showed that TM was safe and well-tolerated with <3% reversible grade 3 or 4 adverse events. Importantly, this trial reported an event-free survival (EFS) of 72% and overall survival (OS) of 84% at a median follow-up of 6.3 years 23. In this trial, the TNBC cohort with stage 4 disease showed EFS of 69% after 2 years; a striking finding as median EFS and OS of stage 4 TNBC patients is less than 8 months and 12 months, respectively, from multiple trials 24, 25. Advancing TM into larger randomized phase II trials will be facilitated by a better understanding of the mechanisms by which copper depletion impacts metastasis and may also inform patient selection for future trials. Copper ions are essential for biological function yet are severely detrimental when present in excess. At the molecular level, copper ions catalyze the production of hydroxyl radicals that can irreversibly alter essential bio-molecules. Hence, selective copper chelators that can remove excess copper ions and alleviate oxidative stress will help assuage copper-overload diseases. However, most currently available chelators are non-specific leading to multiple undesirable side-effects. The challenge is to build chelators that can bind to copper ions with high affinity but leave the levels of essential metal ions unaltered. Here we report the design and development of redox-state selective Cu ion chelators that have 10 8 times higher conditional stability constants toward Cu 2+ compared to both Cu + and other biologically relevant metal ions. This unique selectivity allows the specific removal of Cu 2+ ions that would be available only under pathophysiological metal overload and oxidative stress conditions and provides access to effective removal of the aberrant redox-cycling Cu ion pool without affecting the essential non-redox cycling Cu + labile pool. We have shown that the chelators provide distinct protection against copper-induced oxidative stress in vitro and in live cells via selective Cu 2+ ion chelation. Notably, the chelators afford significant reduction in Cu-induced oxidative damage in Atp7a −/− Menkes disease model cells that have endogenously high levels of Cu ions. Finally, in vivo testing of our chelators in a live zebrafish larval model demonstrate their protective properties against copper-induced oxidative stress.

Copper-rich foods are the easiest and most natural way of getting more copper into the body. The best sources of food-based copper include varieties of seafood and sea vegetables, animal organ meats and legumes. For anyone living with Menkes disease, a copper supplement is more than just a supplement; it’s a lifeline.If you’re in good health, you’re not likely to have low levels of copper. Symptoms of copper deficiency may include:
