This structural feature is central to hypotheses regarding how GHK-Cu influences gene expression networks: transcriptomic studies have reported association with the regulation of hundreds of genes linked to tissue remodeling, antioxidant defense, and inflammatory signaling pathways, making it a useful molecular probe in cell biology research
However, it is important to emphasise that whilst these mechanisms are biologically plausible, there is insufficient high-quality clinical evidence for glutathione supplementation as a treatment for fatty liver disease
Previous studies showed that FCGR3A + monocytes expressed high levels of CD47 and LILR genes, which enhanced paracrine signaling pathways and promoted T cell infiltration (2)
Studies have investigated its reported role in fibroblast activity, collagen- and elastin-synthesis signalling, and matrix-metalloproteinase regulation across skin, wound, and nerve tissue models, alongside models examining anti-inflammatory signalling and DNA-repair pathway modulation
