1. GHK unterdrückt die Fibrinogensynthese
Fibrinogen consists of three polypeptide chains; alpha, beta, and gamma. GHK strongly suppresses the gene for the beta chain of fibrinogen. A lack of adequate FGB will effectively stop fibrinogen synthesis since equal amounts of all three polypeptide chains are needed to produce fibrinogen.
GHK also suppresses the production of the inflammatory cytokine interleukin-6 (IL-6) which is a main positive regulator of fibrinogen synthesis, through its interaction with fibrinogen genes. In cell culture systems, GHK suppresses IL-6 secretion in skin fibroblasts and IL-6 gene expression in SZ95 sebocytes. In summary, the effects of GHK on the FGB gene plus its effects on IL-6 production imply a suppression of overall fibrinogen production.
2. GHK aktiviert das Ubiquitin/Proteasom -System (UPS)
Die UPS entfernt beschädigte Proteine. Höhere Aktivitäten der UPS scheinen die Alterungseffekte zu verzögern. GHK stimulierte die Genexpression in 41 UPS -Genen und unterdrückte nur 1 UPS -Gen.
3. GHK aktiviert DNA -Reparaturgene
DNA -Schäden werden in jungen und gesunden Zellen sofort repariert, wenn wir mit zunehmendem Alter von DNA -Schäden ansammeln. Das Zurücksetzen der Aktivität von DNA -Reparaturgenen kann schädliche Auswirkungen des Alterns verringern. GHK war in erster Linie stimulierend für DNA -Reparaturgene (47 nach oben, 5 unten).
4. GHK fungiert als Antioxidans
Freie Radikale und toxische Endprodukte der Lipidperoxidation sind mit Atheriosklerose, Krebs, Katarakten, Diabetes, Nephropathie, Alzheimer -Krankheit und anderen schweren pathologischen Erkrankungen des Alterns verbunden. GHK stimuliert 14 antioxidative Gene und unterdrückt zwei prooxidative Gene.
5. GHK unterdrückt Insulin- und Insulin-ähnliche Gene
The insulin family has been proposed as a negative controller of longevity; higher levels of insulin and insulin-like proteins reduce lifespan. GHK stimulates 3 genes in this system and suppresses 6 genes.
The insulin/IGF-1- like receptor pathway is a contributor to the biological aging process in many organisms. The gene expression data suggests that GHK suppresses this system as 6 of 9 of the affected insulin/IGF-1 genes are suppressed. Insulin/IGF-1-like signaling is conserved from worms to humans. In vitro experiments show that mutations that reduce insulin/IGF-1 signaling have been shown to decelerate the degenerative aging process and extend lifespan in many organisms, including mice and possibly humans. Reduced IGF-1 signaling is also thought to contribute to the “antiaging” effects of calorie restriction.
6. GHK repariert das Gewebe durch TGF -Superfamilie
The most explored of GHK’s actions is the repair of damaged tissues (skin, hair follicles, stomach and intestinal linings, and boney tissue) either by the use of copper-peptide-containing creams or by induction of systemic healing.
Campbell et al. found that GHK’s resetting of gene expression of fibroblasts from COPD patients fits into this category of tissue repair via the TGF beta superfamily. Campbell et al. also found that GHK directly increases TGF beta and other family members which activate the repair process.
7. Krebskontrollierende Gene
Caspase, growth regulatory, and DNA repair genes are important in cancer suppression. In 2010, Hong et al. identified 54 genes associated with aggressive, metastatic, human colon cancer. The Broad Institute’s Connectivity Map was used to find compounds that reverse the differential expressions of these genes. The results indicated that two wound healing and skin remodeling molecules, GHK at 1 micromolar and securinine at 18 micromolar, could significantly reverse the differential expression of these genes and suggested that they may have a therapeutic effect on the metastasis-prone patients.
Fazit
The tripeptide GHK possesses many positive effects but declines with age. It improves wound healing and tissue regeneration (skin, hair follicles, stomach and intestinal linings, and boney tissue), increases collagen and glycosaminoglycans, stimulates synthesis of decorin, increases angiogenesis, and nerve outgrowth, possesses antioxidant and anti-inflammatory effects, and increases cellular stemness and the secretion of trophic factors by mesenchymal stem cells. Recently, GHK has even been found to reset genes of diseased cells from patients with cancer or COPD to a healthier state.
GHK exhibits minimal side effects, low oral and excellent subcutaneous bioavailability in mice. Per kg dosage in mice does not scale to humans. GHK for sale at
