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
Homo sapiens (human)

Colorectal cancerThis series is part of our curated briefing on it.
Samples

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.

Genomic and cellular responses to aspirin in colonic organoids from African- and European-AmericansPhysiological genomics · 2025
Summary (written by the submitters)
Aspirin (ASA) is a proven chemoprotective agent for sporadic and hereditary colorectal cancer (CRC), though mechanisms underlying these effects are incompletely understood. Human-derived epithelial organoids are an ideal system to study host-environment interactions in the colon across individuals. Here, colonic organoids from a diverse cohort of African-Americans (AA) and European-Americans (EA) were used to profile genomic and cellular ASAresponses.

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 GSE239425_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 PRJNA999280 and SRA study SRP451798. Searching any of these in the dataset finder brings you back here.
