Tissue remodeling follows the initial phase of wound healing and stops inflammatory and scar-forming processes, then restores the normal tissue morphology. The human peptide Gly-(L-His)-(L-Lys) or GHK, has a copper 2+ (Cu(2+)) affinity similar to the copper transport site on albumin and forms GHK-Cu, a complex with Cu(2+). These two molecules activate a plethora of remodeling related processes: (1) chemoattraction of repair cells such as macrophages, mast cells, capillary cells; (2) anti-inflammatory actions (suppression of free radicals, thromboxane formation, release of oxidizing iron, transforming growth factor beta-1, tumor necrosis factor alpha and protein glycation while increasing superoxide dismutase, vessel vasodilation, blocking ultraviolet damage to skin keratinocytes and improving fibroblast recovery after X-ray treatments); (3) increases protein synthesis of collagen, elastin, metalloproteinases, anti-proteases, vascular endothelial growth factor, fibroblast growth factor 2, nerve growth factor, neutrotropins 3 and 4, and erythropoietin; (4) increases the proliferation of fibroblasts and keratinocytes; nerve outgrowth, angiogenesis, and hair follicle size. GHK-Cu stimulates wound healing in numerous models and in humans. Controlled studies on aged skin demonstrated that it tightens skin, improves elasticity and firmness, reduces fine lines, wrinkles, photodamage and hyperpigmentation. GHK-Cu also improves hair transplant success, protects hepatic tissue from tetrachloromethane poisoning, blocks stomach ulcer development, and heals intestinal ulcers and bone tissue. These results are beginning to define the complex biochemical processes that regulate tissue remodeling.

One of complications associated with long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) is peptic ulcer. Recently, we found that orally administered phosphatidic acid (PA) ameliorated aspirin-induced stomach lesions in mice. In this study, we identified PA-rich food sources and examined the effects of the food materials on indomethacin-induced stomach ulcer. Among examined, buckwheat (Fagopyrum esculentum) bran contained the highest level of PA (188 mg/100 g). PA was the richest phospholipid (25%) in the lipid fraction of the buckwheat bran. Administration of the lipid extracts of buckwheat bran significantly ameliorated indomethacin-induced stomach lesions in mice. In contrast, wheat (Triticum durum) bran lipids (PA, 4%) and soybean (Glycine max) lipids (PA, 3%) were not associated with ameliorative effects. These results indicated that PA-rich lipids can be used as an effective supplement for prevention of NSAID-induced stomach ulcer.
