The mechanisms involve IGF-1-mediated stimulation of cellular proliferation, enhanced protein synthesis, and activation of anti-inflammatory pathways
Corresponding with the aforementioned analysis, in MAFLD rats treated with metformin, there was a notable increase in the expression of DNA-binding transcriptional response regulator, NtrC family, contains REC, AAA-type ATPase, and a Fis-type DNA-binding domains, Methylaspartate ammonia-lyase, tRNA C32,U32 (ribose-2-O)-methylase TrmJ or a related methyltransferase, Predicted dienelactone hydrolase, Intracellular sulfur oxidation protein, DsrE/DsrF family, 23S rRNA U2552 (ribose-2-O)-methylase RlmE/FtsJ, and 3-oxoacyl-[acyl-carrier-protein] synthase III compared to normal rats and untreated MAFLD rats
It's a function of the peptide's pharmacokinetics and the enzyme it targets

It appears within the collagen alpha-2(I) chain and is described in the literature as being liberated by proteolysis during tissue remodeling, which gives it a plausible endogenous source and makes it one of the very few compounds in this catalog with a non-hypothetical physiological counterpart
