Paper
An Isoform-Specific RUNX1C-BTG2 Axis Governs AML Quiescence and ChemoresistanceBlood cancer discovery · 2025
Summary (written by the submitters)
Aberrant splicing is a hallmark of many cancers, including Acute Myeloid Leukemia (AML), but its role in post-treatment relapse remains poorly understood. Here, we analyzed the alternative splicing landscape of 19 AML patients during chemotherapy treatment. We found an upregulation of the long isoform of the transcription factor RUNX1 (also known as RUNX1C) in relapsed cohorts, which conferred chemotherapy resistance.

Notably, these patients showed elevanted intragenic DNA methylation at the RUNX1 proximal promoter, thereby activating RUNX1C transcript through its alternative distal promoter. Mechanistically the N-terminus region of RUNX1C is required to promote chemoresistance by regulating a distinct RUNX1 transciptional program. Among these target genes, B-cell translocation gene 2 (BTG2) mediates a quiescent-like phenotype by deadenylating ribosomal RNAs to reduce global protein synthesis. Lastly, we harnessed orthogonal RNA-targeting strategies to target RUNX1C isoform, which led to augmented chemotherapy efficacy. Collectively, our finidngs delineate a transcriptional circuity orchestrated by a transcription factor isoform that underpins chemotherapy responsiveness and a potential therapeutic strategy to mitigate disease recurrence.

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 GSE273034_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.

Also filed as BioProject PRJNA1139820 and SRA study SRP521993. Searching any of these in the dataset finder brings you back here.
