Copper is essential to wound healing as well as a widespread environmental pollutant, with skin aging potential. Wound healing and skin aging are facilitated by matrixmetalloproteinases (MMP), which remodel the extracellular matrix, and interleukin-8 (IL-8), linked with copper. This research investigated the mechanism to copper's role in wound healing or skin aging by regulation of MMP-1 and IL-8 genes. It examined the dose-responsive effects of copper on MMP-1, -2, and -9 activities; MMP-1 and IL-8 gene regulation at protein, mRNA, and promoter levels; tissue inhibitor of matrixmetalloproteinases-1 (TIMP-1) expression; and cell proliferation. Copper stimulated cell proliferation and the expression of MMP-1 and IL-8 genes at the protein, mRNA, and promoter levels, indicating transcriptional regulation, without significantly altering TIMP-1. The research suggests that copper facilitates wound healing as well as skin aging via the induction of MMP-1 expression, with limiting MMP effect at the higher concentrations through enhanced IL-8 expression, which favors extracellular matrix deposition.
