Comparison
While FOXO4-DRI acts as a senolytic in preclinical models by promoting apoptosis of senescent cells, improving tissue function and healthspan measures in aged animals38, Matrixyl is a widely used cosmetic peptide with evidence of stimulating extracellular matrix synthesis and reducing wrinkle appearance in skin-care formulations48.
While FOXO4-DRI works as a D-retro-inverso peptide derived from a FOXO4 region that competes with endogenous FOXO4 for binding to p53, thereby releasing p53 to trigger apoptosis selectively in senescent cells38, Matrixyl is a palmitoylated pentapeptide, Pal-Lys-Thr-Thr-Lys-Ser (Pal-KTTKS), that acts as a matrikine, signaling to dermal fibroblasts to increase production of collagen, elastin, fibronectin, and other ECM components4858.
FOXO4-DRI is amino acids long, whereas Matrixyl is longer as it has a length of 5 amino acids. FOXO4-DRI is made up of a sequence of sequence data not available in the current dataset. Matrixyl is made up of a sequence of Lysine, Threonine, Threonine, Lysine, Serine.
