KAT6A chimeras form a self-reinforcing epigenetic module with NURF and MLL/COMPASS to sustain AMLGenome biology · 2025
Summary (written by the submitters)
KAT6A-CBP (K/C) and KAT6A-P300 (K/P) fusions are recurrent genetic alterations in acute myeloid leukemia(AML) that are associated with poor prognosis. The large size of these fusion proteins has posed challenges in developing preclinical models, limiting mechanistic studies. To address this, we employed 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.
Read the full summary ↓
Genomic profiling revealed that KAT6A fusions preferentially localize to H3K4me2/3-marked regions and interact with the Nucleosome Remodeling Factor (NURF), a critical H3K4me2/3 reader. Disrupting NURF-chromatin interactions impaired K/C recruitment to target loci and disrupted MLL/COMPASS-mediated H3K4me2 deposition, thereby establishing an epigenetic regulatory module involving KAT6A chimeras, NURF, and MLL/COMPASS. Concurrently, CBP/P300 inhibition reduced histone acetylation, chromatin accessibility, and genomic targeting of the module. Therapeutically, NURF inhibition induced cell cycle arrest and suppressed leukemia proliferation, while CBP/P300 inhibition promoted leukemia differentiation. Both strategies demonstrated promising efficacy in K/C murine models, with superior effects observed with combined NURF and CBP/P300 inhibition. These findings uncover a self-reinforcing epigenetic module centered on histone reader proteins and modifying enzymes, providing mechanistic insights into KAT6A-rearranged AML and identifying promising combinatorial therapeutic vulnerabilities.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE299379_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.
