Biased activation of human T lymphocytes due to low extracellular pH is antagonized by B7/CD28 costimulation
Copper Delivery & Enzymatic Cofactor Function Copper ion delivery GHK-Cu acts as a copper delivery system, transporting copper ions to tissues where they serve as essential cofactors for enzymatic processes critical to wound healing and collagen synthesis Copper-dependent enzymes Copper is required for enzymes including lysyl oxidase (involved in collagen and elastin cross-linking), superoxide dismutase (an antioxidant enzyme), and cytochrome c oxidase (involved in cellular respiration) Collagen & Extracellular Matrix Remodeling Stimulates collagen synthesis GHK-Cu has been shown to increase collagen production in dermal fibroblasts, enhancing the structural integrity of connective tissues Glycosaminoglycan stimulation Promotes the production of glycosaminoglycans (GAGs), including hyaluronic acid, critical components of the extracellular matrix that contribute to tissue hydration and resilience Modulates matrix metalloproteinases (MMPs) Regulates the balance between matrix synthesis and degradation, facilitating tissue remodeling and wound repair Antioxidant & Anti-Inflammatory Properties Reduces oxidative stress Exhibits antioxidant properties, protecting cells from damage caused by reactive oxygen species (ROS) Anti-inflammatory effects Modulates inflammatory responses, reducing pro-inflammatory cytokine production and promoting resolution pathways Protective effects In dermal fibroblasts, GHK-Cu has been shown to alleviate UV-induced oxidative stress by increasing the expression of antioxidant enzymes including SOD-1, NQO1, and catalase Gene Expression Modulation Age-related gene expression DNA microarray studies have shown that GHK-Cu can modulate gene expression, resetting the transcriptional profile of aged cells toward a more youthful state Tissue remodeling gene networks Upregulates genes associated with tissue repair and extracellular matrix organization while downregulating genes associated with inflammation and cellular senescence CAS Number: 89030-95-5 (copper complex) or 49557-75-7 (GHK base) Molecular Formula: CHCuNO Molecular Weight: 403.90 g/mol (copper complex) Purity: 98% (HPLC) Form: Lyophilised powder Quantity: 100mg per vial Laboratory research compound evaluated in controlled preclinical settings
However, it has been observed that a significant group of patients with breast cancer relapsed with the endocrine therapy-resistant disease
