GlyNAC is a 1:1 combination of glycine and N-acetylcysteine
The ATF4-mediated upregulation of amino acid transporters and one-carbon metabolism, including SLC1A1, SLC7A8 , and SHMT2 , presumably increases the supply of glutamate, cysteine, and glycine, which might act in concert for the biosynthesis of GSH
In these models, homozygous mutation of either Prop1 or Pit1 genes cause an abnormal development of the anterior pituitary, which in turn leads to decline in production of GH, thyrotropin (TSH), and prolactin (PRL), with consequent decrease in circulating IGF-I and thyroxine levels (Bartke, 2011)
