This process relies on KLF1 (Krueppel-like factor 1), FOXO3 (forkhead box O3), and E2F2 transcription factors, chromatin condensation-regulating caspase-3, DNA methylation-regulating Tet family proteins, Asxl1, cytoskeleton-regulating Rho GTPases, and p38 MAPK signaling [51, 52]
The intranasal GHK-Cu treatment was found to delay cognitive impairment, reduce amyloid plaques, and lower inflammation levels in the frontal cortex and hippocampus .37 Randomized controlled trials in human patients are needed to confirm the benefit of GHK-Cu for cognitive decline and Alzheimers disease as well as to evaluate safe and effective human dosing (the human dose equivalent of 15mg/kg in mice would be ~1.2mg/kg, though data on this or any other dosing nasally in humans is not currently available), but preliminary animal trials are promising
