Moreover, the authors performed q RT-PCR to quantify Nrf2 mRNA expression, demonstrating that quercetin upregulated this key antioxidant transcription factor while restoring endogenous antioxidant enzyme activity and reducing tissue damage (Sharma et al., 2020

Multiple mechanisms including loss-of-function mutations in the genes encoding NRF2 or small Mafs, oxidation or epigenetic modification of the NRF2 promoter, or changes in the other factors that modulate NRF2 (such as kinases, phosphatases, or DNA binding proteins) have been suggested to contribute to the suppression of NRF2 activity during ageing
Understanding copper peptides and GHK-Cu fundamentals Before evaluating specific products, understanding what copper peptides actually are and how they work provides essential context for making informed choices
