A biological miracle is happening in anti aging where the body takes out the trash. The peptide reduced frailty markers by 50% in aged mice, inducing apoptosis (death) only in damaged cells. It FOXO4 DRI 10MG Raw Amino FOXO4 peptide targets myofibroblast ameliorates bleomycininduced pulmonary fibrosis in mice through ECMreceptor interaction pathway Han 2022 Journal of Cellular and Molecular Medicine Wiley Online Library The FOXO4 peptide in a DRI conformation (D amino acids in a retro reversed sequence), henceforth named FOXO4 DRI, competes with FOXO4 for p53 binding in a dose dependent manner and doing so with higher affinity.
