Peptide Inhibitors Targeting FOXO4-p53 Interactions and Inducing Senescent Cancer Cell-specific Apoptosis.
Article in Journal of medicinal chemistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cellular senescence, marked by irreversible cell cycle arrest and senescence-associated secretory phenotype, contributes to aging and cancer recurrence. While chemotherapy can induce senescence in cancer cells, these therapy-induced senescent cells often resist apoptosis and promote tumor recurrence. The nuclear interaction between FOXO4 and p53 is crucial for senescent cell survival. Using NMR spectroscopy, we identified that hydrophobic interactions in the p53 transactivation domain play a key role in FOXO4 forkhead domain binding. Based on this structural information, we designed an optimized peptide inhibitor with reduced negative charges and incorporated a cationic cell-penetrating peptide for enhanced cellular delivery (CPP-CAND). CPP-CAND exhibited high selectivity for senescent cells, effectively disrupting nuclear FOXO4-p53 foci and inducing caspase-dependent apoptosis. Notably, it showed cytotoxicity against senescent cancer cells induced by different chemotherapeutic agents including doxorubicin and cisplatin. With its enhanced selectivity, l-amino acid composition, and shorter length, CPP-CAND represents a promising therapeutic candidate for targeting therapy-induced senescent cancer cells.
