It upregulates genes involved in collagen synthesis (COL1A1, COL3A1, COL5A1), extracellular matrix remodeling (decorin, fibromodulin), and antioxidant defense (superoxide dismutase, glutathione peroxidase) while simultaneously suppressing genes associated with inflammation (IL-6, TNF-alpha), fibrinogen production, and tissue destruction (several MMPs)
It differs from native IGF-1 in that it possesses an arginine instead of a glutamic acid at the third position in its amino acid sequence, and also has an additional 13 amino acids at its N-terminus (MFPAMPLLSLFVN), for a total of 83 amino acids relative to the 70 of native IGF-1
Nicotinamide riboside kinases regulate skeletal muscle fiber-type specification and are rate-limiting for metabolic adaptations during regeneration
