Comparison
While KPV is investigated as an anti-inflammatory and barrier-protective agent in skin and mucosal models, reducing pro-inflammatory cytokines and promoting tissue repair684, MGF is upregulated in muscle after mechanical overload, where it supports tissue repair and growth; recombinant forms are studied for regenerative and performance-enhancement effects22138.
While KPV works as the C-terminal Lys-Pro-Val tripeptide fragment of α-MSH, which exerts potent anti-inflammatory effects largely via inhibition of NF-κB signaling and modulation of cytokine expression, with many actions independent of classical melanocortin receptor activation684, MGF is a 24-amino-acid E-peptide splice variant of IGF-1 (IGF-1Ec) produced in mechanically stressed or damaged muscle that activates IGF1R and local anabolic pathways involved in muscle repair and hypertrophy22138144.
KPV is 3 amino acids long, whereas MGF is longer as it has a length of 24 amino acids. KPV is made up of a sequence of Lysine, Proline, Valine. MGF is made up of a sequence of Tyrosine, Glutamine, Proline, Proline, Serine, Threonine, Asparagine, Lysine, Asparagine, Threonine, Lysine, Serine, Glutamine, Arginine, Arginine, Lysine, Glycine, Serine, Threonine, Phenylalanine, Glutamic acid, Glutamic acid, Arginine, Lysine.
