FOXO4-DRI — living evidence map
The Atlas page holds the claims; this is how its evidence evolved.
Summary
FOXO4-DRI is a peptide designed to disrupt the interaction of FOXO4 with p53, which in senescent cells causes p53 nuclear exclusion and cell-intrinsic apoptosis. · pmid:28340339
Mechanism
NMR structures show the disordered peptide binding the disordered p53 transactivation domain 2 as a transiently folded complex, with both its FOXO4-derived region and its cell-permeability segment contributing. · pmid:40593617
History
In mice it neutralized doxorubicin-induced chemotoxicity and restored fitness, fur density and renal function in both fast-ageing and naturally aged animals. · pmid:28340339
Identity
PubChem CID 167312269: Foxo4-dri, C228H388N86O64, 5358 g/mol. · pubchem:167312269
CAS registry number 2460055-10-9. · pubchem:167312269
Where the evidence actually sits
Proportion of the 2 claims about FOXO4-DRI standing at each tier. Community volume is shown on the Consensus tab beside this and is never averaged into it.
Living evidence history
2 resolved citations, oldest to newest, coloured by tier. Retractions and contradictions land here as they are recorded.
Structure
No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for FOXO4-DRI yet.
Dose evidence, rung by rung
No established safe human dose. Nothing on file establishes one. That is a statement about the evidence PepJunkie holds, not a promise about the molecule.
