At their core, peptides are small chains of amino acids that act like signaling molecules in the body

H4K12la, catalyzed by lactyltransferase p300 at histone H4 lysine 12, is enriched at the glutamate-cysteine ligase catalytic subunit (GCLC) promoter region, enhancing glutathione synthesis, inhibiting lipid peroxide accumulation and ultimately blocking the ferroptosis pathway (51)

AOD-9604 offers a distinct, IGF-1-independent lipolysis mechanism worth studying in its own right

Not surprisingly, many of these extra signaling domains are derived from important checkpoint inhibitor pathways

Homogenized tissue samples were processed identically to the cell suspension samples (with SPE sample clean-up for the acid extractions)
