Immunoblotting Cells were washed with PBS and lysed with lysis buffer (150 mM NaCl, 20 mM EDTA, 50 mM Tris-HCl, 0.5% NP-40) containing protease and phosphatase inhibitors

Choi et al., 2016, reported that piceatannol (a resveratrol metabolite found in red wine) affected HDAC expression in a mouse model and concluded that it may be a valuable therapeutic agent in renal fibrosis by decreasing HDAC4 and HDAC5 protein expression [264]

Free Cu2+ is toxic (Fenton reactions, hydroxyl radicals), but the GHK-Cu complex is stable, diffusible and delivers copper in a targeted manner to copper-dependent metalloenzymes: lysyl oxidase (collagen/elastin crosslinking), Cu/Zn superoxide dismutase (SOD1, antioxidant defence), tyrosinase (controlled melanogenesis), dopamine-beta-hydroxylase

For biohackers, its a peptide worth watching, but with an informed eye on risk, variability, and lack of regulatory oversight
