Copper is required for oncogenic BRAF signalling and tumorigenesis. Nature 509, 492–496 (2014). Ironically, both copper deficiency and copper overdose can lead to anemia. This is but one of many symptoms that come as a risk of consuming too much copper as a supplement. Others include nausea, vomiting, low blood pressure, fevers, diarrhea featuring blood, and intense abdominal pain.As a result, many current studies focus on copper chelation therapy. Copper chelators bind to copper ions to reduce their activity, remove them from cells, or transport them between cells. Ge, E. J. et al. Connecting copper and cancer: from transition metal signalling to metalloplasia. Nat Rev Cancer https://doi.org/10.1038/s41568-021-00417-2 (2021). The three main branches of copper supplements are 1) pure copper, 2) copper with other binding ingredients, and 3) copper present in multivitamin compounds. All of these different supplements will make use of a number of different forms of copper , namely cupric oxide, cupric sulfate, copper amino acid chelates, and copper gluconate. Although this can look a bit daunting at first sight, all that is happening is that first you have one, then two, then three, then four water molecules in total replaced by ammonias. Fractions were analyzed by LC–MS/MS using a nanoAQUITY UPLC (Waters) with a 50 cm (inner diameter 75 µm) EASY-Spray Column (PepMap RSLC, C18, 2 µm, 100 Å) heated to 60 °C coupled to an Orbitrap Fusion Lumos Tribrid Mass Spectrometer (Thermo Fisher Scientific). Peptides were separated at a flow rate of 300 nL/min using a linear gradient of 1–35% acetonitrile (0.1% FA) in water (0.1% FA) over 4 h and analyzed by SPS-MS3. MS1 scans were acquired over a range of m/ z 375–1500, 120K resolution, AGC target of 4 × 10 5, and maximum IT of 50 ms. MS2 scans were acquired on MS1 scans of charge 2–7 using isolation of 0.7 m/ z, collision-induced dissociation with activation of 35%, turbo scan and max IT of 50 ms. MS3 scans were acquired using specific precursor selection (SPS) of 10 isolation notches, m/ z range 100–1000, 50K resolution AGC target of 1e 5. Differentially expressed proteins (log2 fold change>1 or <−1 and p< 0.05) were identified. TMT data analysis

You will often find these values quoted as log K 1 or whatever. All this does is tidy the numbers up so that you can see the patterns more easily. This condition is commonly called Menkes kinky hair syndrome because one of its characteristics is sparse, kinky hair. Risk factors for copper deficiency

Navarrete-Perea, J., Yu, Q., Gygi, S. P. & Paulo, J. A. Streamlined tandem mass tag (SL-TMT) protocol: an efficient strategy for quantitative (phospho)proteome profiling using tandem mass tag-synchronous precursor selection-MS3. J. Proteome Res 17, 2226–2236 (2018). LM2 cells were plated in five replicates for each treatment, where at the end of the treatment period (72 h), there were approximately a million cells per well. At the end of treatment, cell number was determined from a single well for each condition, and four remaining replicates were used for metabolites extraction. Cells were washed with PBS (1×, w/o Ca 2+/Mg 2+), and metabolites were extracted with cold 80% methanol (1 mL/well). After overnight incubation at −80 °C, samples were vortexed and centrifuged at 20,000 × g for 20 min to remove protein. Supernatants were dried in a vacuum evaporator (Genevac EZ-2 Elite) for 3 h. For metabolomic profiling dried extracts were resuspended in 50 μL of 97:3 water:methanol containing 10 mM tributylamine and 15 mM acetic acid. Samples were vortexed, incubated on ice for 20 min, and clarified by centrifugation at 20,000 × g for 20 min at 4 °C. Ion pair LC–MS analysis was performed with LC separation on a Zorbax RRHD Extend-C18 column (150 mm × 2.1 mm, 1.8 μm particle size, Agilent Technologies), and using a gradient of solvent A (10 mM tributylamine and 15 mM acetic acid in 97:3 water:methanol) and solvent B (10 mM tributylamine and 15 mM acetic acid in methanol) according to the manufacturer’s instructions (MassHunter Metabolomics dMRM Database and Method, Agilent Technologies). The acquisition was performed using an Agilent 6470 LC/MS/MS triple quadrupole. MasHunter Workstation Software for Quantitative analysis B.09 (Agilent Technologies), RStudio v1.3. and GraphPadPrism v8 and v9 were used for data analysis. Immunostaining and microscopyReading copper deficiency symptoms online, and self-diagnosing based on where you think your copper levels are at, is risky business. It is not recommended to take this route, even if you are only intending to take 10 mg of copper or less. LeBleu, V. S. et al. PGC-1α mediates mitochondrial biogenesis and oxidative phosphorylation in cancer cells to promote metastasis. Nat. Cell Biol. 16, 1001–1015 (2014). 992–1003. Our phase II clinical trial of TM (NCT00195091) 23, showed no difference in outcomes among the different molecular subtypes in patients who were stage 4 NED (no evidence of disease). Indeed, at a median follow-up of 9.4 years, EFS for patients with the poorest prognosis was 63.6% for luminal breast cancers, 50% for Her2+ and 59.3% for TNBC (Fig. 1d). EFS of 59.3% was particularly striking in patients who had TNBC and were stage 4 without evidence of disease, as a median EFS of less than 8 months has been observed in previous trials 24, 25. These observations provide a strong rationale for the development of copper chelation as a therapeutic strategy in breast cancer patients with advanced disease. However, advancing TM into larger randomized phase II trials would be facilitated by a clearer understanding of the mechanistic basis by which copper depletion impairs metastatic progression, and this would also subsequently facilitate patient selection for TM treatment. Learning how to reap the rewards of food-derived copper eliminates all need for supplement use. However, food-derived copper is usually only a suitable option for individuals with low levels of copper deficiency. The average diet will only give the eater roughly 1 mg of extra copper per day. What it all boils down to is that taking copper supplements safely is simply a game of accurate dosage. Knowing where you stand in relation to copper in your body is the foundation upon which a safe and beneficial copper supplement regime can be built.
