Five Core Biological Actions The 2015 and 2018 Pickart and Margolina reviews catalog the biological actions of GHK-Cu across in vitro, animal, and human studies 1 2
Their activity in mitophagy is regulated by phosphorylation: The phosphorylation of BNIP3 at Ser17 and Ser24 within its LIR motif is essential for LC3B interaction (86), while the phosphorylation of NIX at Ser34 and Ser35 enables it to bind with GABARAP family proteins (87)
Interestingly, a recent study examining the time-dependent effect of low IGF-1 levels on aging outcomes observed that a targeted reduction in liver-derived IGF-1 early (10 d or 5 mo) or later in life (15 mo) improved aspects of lifespan in females, though these effects were most pronounced when IGF-1 was reduced at 5 mo old 19
