What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Mus musculus (mouse)
Samples
18 samples: 6 conditions, mostly in triplicateGroups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.

Microbial metabolite drives ageing-related clonal haematopoiesis via ALPK1Nature · 2025
Summary (written by the submitters)
Despite the known associations between CHIP and increased all-cause mortality, our understanding of environmental and regulatory factors that underlie this process during aging remain rudimentary. Here we report that intestinal alterations, which can occur with age, lead to systemic dissemination of a microbial metabolite that promotes leukemic cell expansion.
Read the full summary ↓
Specifically, we show that ADP-D-glycero-b-D-manno-heptose (ADP-heptose), a biosynthetic bi-product specific to gram-negative bacteria, is uniquely found in the circulation of older individuals and favors the expansion of pre-leukemic hematopoietic stem cells. Mechanistically, ADP-heptose binds its receptor, ALPK1, triggering transcriptional reprogramming that endows pre-leukemic cells with a competitive advantage. Thus, the accumulation of ADP-heptose represents a direct link between aging and expansion of rare pre-leukemic cells, suggesting that the ADP-heptose-ALPK1 axis is a promising therapeutic target to prevent progression of CHIP to overt leukemia and immune-related conditions.

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 GSE232794_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 PRJNA973978 and SRA study SRP438448. Searching any of these in the dataset finder brings you back here.

Study design
6 conditions, mostly in triplicate
WT-H ×3 WT-A ×3 DM-H ×3 DM-A ×3 DMA-H ×3 DMA-A ×3

Supports a between-group comparison across 18 samples.

How we read this: 6 replicated groups read from 18 sample titles; they account for 18 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.
