Peptide inhibitors targeting FOXO4 p53 interactions and inducing senescent cancer cell specific apoptosis bioRxiv Peptide Inhibitors Targeting FOXO4 p53 Interactions and Inducing Senescent Cancer Cell specific Apoptosis Journal of Medicinal Chemistry Peptide inhibitors targeting FOXO4 p53 interactions and inducing senescent cancer cell specific apoptosis bioRxiv FOXO4 DRI induces keloid senescent fibroblast apoptosis by promoting nuclear exclusion of upregulated p53 serine 15 phosphorylation Communications Biology Directly from the paper covered by the post earlier, 90 year old equivalent mouse before and after treatment with FOXO4 D reverso inversio peptide, a FOXO4 inhibitor that blocks FOXO4 from arresting senescent cell apoptosis.
