Neutral amino acid transport by the blood-brain barrier
This is achieved mainly by contributing to the methionine cycle (Zhou et al., 2017) and the SIRT1 pathway (Zhou et al., 2018b), inhibiting hypermethylation of promoter associated with GSH synthesis-related genes, and activating the adenosine 5-monophosphate (AMP)-activated protein kinase (AMPK) pathway (Zhou et al., 2018a)
However, more scientific proof is needed to further investigate its use
This method has been described in our previous publications, where we presented our data on genes relevant to nervous system function, antioxidant system, ubiquitin-proteosome system, skin health and tissue regeneration affected by GHK [ 31 , 32 , 33 , 34 ]
