Recent evidence shows that HSP70s are involved into transmembrane protein translocation via entropic pulling (Rukes et al., 2024), into the protection of damaged muscle fibers via calcium reuptake from the sarcoplasm to the reticulum (Zeng et al., 2025)
This revealed its antioxidative role in reducing oxidative stress and contributing to the inhibition of melanin synthesis by modulating the GSH redox balance ( In vitro , PYC exhibits antioxidant effects during adipogenesis by downregulating the mRNA expression of pro-oxidant enzymes, such as nicotinamide adenine dinucleotide phosphate hydrogen oxidase 4 and glucose-6-phosphate dehydrogenase, while simultaneously upregulating antioxidant enzymes, including Cu/Zn-SOD, Mn-SOD, GPx, and GSH reductase ( ex vivo studies show that PYC acts synergistically with lutein to reduce oxidative stress in porcine retinal homogenates ( In a study using Escherichia coli mutants, PYC induced the expression of key antioxidant enzymes such as MnSOD and CuZnSOD, particularly under oxidative stress, suggesting a potential antioxidative role ( Similarly, PYC mitigated oxidative stress and inflammation induced by titanium dioxide nanoparticles in both murine lung tissue and human airway epithelial cells ( In a randomized clinical trial involving pediatric patients with attention deficit hyperactivity disorder, PYC treatment produced a modest increase in catalase activity, suggesting potential antioxidant effects (Figure 1) in diverse contexts and experimental models
Hashem et al., 2009
Focus on preserving existing muscle through resistance training 3-4 times weekly and hitting 100g+ protein daily
Thats because it can cause oxygen deprivation, disrupt mitochondrial energy production, and increase oxidative stress
Given that Cu accumulation occurs in a variety of diseases and conditions, including Wilsons disease, certain neurodegenerative diseases, and cancer, it is reasonable to speculate that cuproptosis may play a pathogenic role in these diseases and may therefore serve as a potential therapeutic target
