KAT6A chimeras form a self-reinforcing epigenetic module with NURF and MLL/COMPASS to sustain AML.

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
backgroundKAT6A-CBP (K/C) and KAT6A-P300 (K/P) fusions are recurrent genetic alterations in acute myeloid leukemia (AML) associated with poor prognosis. Despite their strong oncogenic potential, the mechanisms underlying their genomic targeting and leukemogenic function remain unclear. A major challenge has been their large size, which has impeded preclinical model development and mechanistic studies.
resultsWe employ a domain-focused truncation strategy to generate de novo murine models of K/C and K/P fusions, which faithfully recapitulate the morphological, immunophenotypic, and transcriptomic features of KAT6A-rearranged AML. Genomic profiling reveals that KAT6A fusions preferentially localize to H3K4me2/3-marked regions, while biochemical analyses uncover that KAT6A interacts with the Nucleosome Remodeling Factor (NURF), a key H3K4me2/3 reader. Disrupting NURF-chromatin interactions via depletion or small-molecule inhibition of its subunit, Bromodomain PHD Finger Transcription Factor (BPTF), impairs K/C recruitment and disrupts MLL/COMPASS-mediated H3K4me2 deposition, defining a functional epigenetic module involving KAT6A chimeras, NURF, and MLL/COMPASS. Notably, CBP/P300 inhibition reduces histone acetylation and chromatin accessibility, further impairing the recruitment of this epigenetic module. Targeting this module via NURF or CBP/P300 inhibition demonstrates efficacy in K/C leukemia models, with enhanced therapeutic effects observed when combined.
conclusionsOur study identifies a self-reinforcing epigenetic module of histone modifiers and readers in KAT6A-rearranged AML, providing mechanistic insights into the genomic targeting of KAT6A chimeras and highlighting promising combinatorial therapeutic strategies.
