Paper
HoxBlinc lncRNA reprograms CTCF-independent TADs to drive leukemic transcription and HSC dysregulation in NUP98-rearranged leukemiaThe Journal of clinical investigation · 2025
Summary (written by the submitters)
We found NUP98 fusions activate Hoxb-associated lncRNA, HoxBlinc that occupies homeotic/oncogenic topologically associated domain (TAD) boundaries in malignant hematopoiesis. Aberration of HoxBlinc led to recruitment of MLL1 complex and reorganization of homeotic/oncogenicTADs that enhanced chromatin accessibilities and aberrantly activated homeotic/hematopoietic oncogenes defined by Hoxblinc chromatin occupancies in NUP98-PHF23 related murine leukemia cells.
Read the full summary ↓
Eliminated HoxBlinc in NUP98 fusion-driven leukemic cells resulted in loss of Hoxblinc binding, TAD integrity, recruitment of MLL complex, and MLL driven H3K4me3 and chromatin accessibility within the HoxBlinc defined domain in a CTCF independent manner, leading to inhibiting homeotic/leukemic oncogenes and mitigating NUP98 fusion-driven leukemia in xenografted mouse models. Moreover, overexpression of HoxBlinc in mouse bone marrow hematopoietic compartment developed multiple leukemia resembling NUP98-PHF23 knock-in mice via enhancing HoxBlinc binding and TAD formation to transcriptionally expanding HS/PC and myeloid/lymphoid subpopulations leading to leukemogenesis. Our studies reveal a CTCF independent role of HoxBlinc in leukemic TAD organization and oncogenic gene regulatory networks in NUP98-fusion related leukemia.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

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.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE269216_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1120741 and SRA study SRP512151. Searching any of these in the dataset finder brings you back here.

Study design

ATAC_BaF3 ×2 ATAC_961C ×2 ATAC_961C_HoxBlinc_KO ×2 ATAC_HoxBlincTg_BALL ×2 ATAC_WT ×2

Supports a between-group comparison across 10 samples.

How we read this: 5 replicated groups read from 10 sample titles; they account for 10 of them. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
