1 · What the graph read from it

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.

2 · The registry

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

backgroundMantle cell lymphoma (MCL) exhibits distinct biological characteristics and marked molecular heterogeneity, with TP53 mutations associated with particularly poor clinical outcomes. Eprenetapopt (APR-246), a first-in-class mutant p53 reactivator, has shown broad anticancer activity across various tumor types. Palbociclib (PD0332991), a CDK4/6 inhibitor, targets CyclinD1-CDK4/6 complexes to counteract aberrant cell cycle regulation. This project will further explore the anti-tumor efficacy and the potential mechanism of APR-246 combined with PD0332991 in MCL.

methodsIn vitro, through assessments of cell proliferation, apoptosis, ROS levels, comet assays, and measurements of DNA damage and apoptosis-related proteins, along with CDX models in vivo, collectively investigated the synergistic anti-tumor efficacy of APR-246 combined with PD0332991 in MCL. Subsequently, through RNA-seq, along with GO functional annotation, KEGG pathway and GSEA enrichment analyses, we were further elucidated the underlying mechanisms and this was confirmed by UHRF1 rescue or knockdown experiments.

resultsIn vitro, we found that APR-246 combined with PD0332991 showed synergistic inhibiting cell proliferation, enhancing apoptosis, increasing ROS, and promoted DNA damage in mut/del p53 MCL cells. In vivo, we observed synergistic inhibiting tumor growth without significant toxicity in CDX models. For the mechanism, we further inferred that the APR-246 combined with PD0332991 may coordinate downregulation the expression of UHRF1 and BRCA1 to inhibits the homologous recombination (HR) repair pathway.

conclusionThese findings support a rational therapeutic strategy that exploits oxidative genomic instability and synthetic lethality via HR pathway disruption, offering a promising combination therapy for managing mut/delp53 MCL.
