The problem with these diets is that they don't work for everybody
DNA Repair and Antioxidant Genes: Loren Pickart's research highlighted GHK's ability to upregulate a cluster of genes involved in DNA repair mechanisms
After 6 h of treatment the GSH:GSSG ratio had decreased by 85% to 2.6:1 (Figure 5B)
However, after exendin-4 stimulation, the receptor association with clathrin-positive regions increased, an effect that correlates with the known rapid GLP-1R internalisation triggered by exendin-4 (31), with this increase however significantly less pronounced for the GLP-1R V229A compared to WT (F/S = 0.16 0.006 and 0.10 0.004 for WT versus V229A, respectively), in agreement with the reduced internalisation propensity displayed by this mutant receptor (Figure 2H)
