Similarly, and consistent with a previous report of comparable GSTP1 expression in A2780 cells and the cisplatin-resistant derivatives C70 and C200 (Townsend et al, 2002), we did not detect a significant increase in GSTP1 expression in platinum-resistant A2780DPP cells

GHK binds copper because of a specific combination of functional groups that together form a high-affinity copper-coordination site: the N-terminal amine donates one nitrogen ligand, the histidine imidazole donates a second nitrogen ligand, and the deprotonated amide nitrogen of the Gly-His peptide bond donates a third nitrogen ligand
