Copper-Mediated Matrix Remodeling and Gene Expression GHK-Cu promotes extracellular matrix synthesis and remodeling through copper-dependent enzymatic activation and broad genomic effects[4]: Stimulation of collagen and elastin synthesis in fibroblasts Activation of lysyl oxidase for collagen cross-linking Enhanced production of glycosaminoglycans and decorin Modulation of metalloproteinase activity for controlled matrix breakdown Gene expression changes affecting over 30% of human genes , resetting cellular programs toward regenerative states The copper ion serves as an essential cofactor for enzymes involved in collagen synthesis and provides antioxidant protection through superoxide dismutase activation, while the peptide itself influences gene transcription to support healing
