GHK-Cu acts as a signalling peptide, encouraging the body to produce more of its own collagen and elastin to support firmer, smoother and more youthful-looking skin
Although the direct cytotoxic effects of high cellular GSSG levels have been documented in a variety of cell types 33,34,35,36 , our cell culture studies with hepatocytes revealed that increased GSSG accumulation, despite being non-toxic per se, could sensitize hepatocytes to TNF-induced killing, suggesting that GSSG and TNF can synergistically induce hepatocyte death and that GSSG-triggered sensitization to TNF hepatotoxicity represents a clinically relevant process that may account for disease progression in NAFLD
Research shows that the peptide activates a VEGF-independent pathway for nitric oxide production through Src kinase phosphorylation
Elevated cAMP activates PKA and phosphorylates cAMP-response element binding protein (CREB), inhibiting p65/RelA and p50 activation as well as their DNA binding ability by delaying IKB- degradation and competing for the KIX binding site on CREB binding protein (90)
Zepbound is also indicated for people with moderate to severe obstructive sleep apnea and obesity
