FIGURE 9 4 Discussion GHK and its bioactive form, GHK-Cu, have been demonstrated to be safe and effective in various cellular, tissue, and animal models ( In IBD, the expression levels of tight junction proteins such as ZO-1 and Occludin, is generally suppressed, leading to increased intestinal permeability, enhanced pathogen infiltration, and exacerbated inflammatory responses ( in vivo and in vitro experimental models revealed that GHK-Cu upregulates the expression level of Occludin and ZO-1, suggesting its potential role in promoting intestinal barrier repair
A landmark 2009 study found that GHK-Cu reversed the gene expression of older skin cells to look more like young skin cells, upregulating collagen and downregulating inflammatory genes
