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
24 samples: 24 samples, each with a distinct title — no replicated groupsGroups 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.
Paper
Combination LIGHT overexpression and checkpoint blockade disrupts the tumor immune environment impacting colorectal liver metastasesScience advances · 2025
Summary (written by the submitters)
Liver metastases contribute to resistance to cancer immunotherapy across tumor types and thus disrupting the immunosuppressive microenvironment of liver metastases is a therapeutic challenge. The expression of LIGHT, an immunostimulatory cytokine, can increase tumor-infiltrating T cells into colorectal cancer liver metastases and form tertiary lymphoid structures.

We investigated the effect of combined anti-CTLA-4 and LIGHT expression in a mouse model of liver metastasis, demonstrating synergistic effects on tumor control, Treg-mediated suppression, and T cell activation, proliferation, and exhaustion. While intratumoral LIGHT or anti-CTLA-4 alone induced tumor-associated macrophages (TAM), only the combination led to a decrease in TAM and MDSC populations and activation of dendritic cells. The combination of LIGHT and anti-CTLA-4 represents a strategy of overcoming immunosuppression in colorectal cancer as well as other microsatellite stable tumors in which liver metastases drive resistance to immunotherapy.

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 GSE252597_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 PRJNA1061481 and SRA study SRP482104. Searching any of these in the dataset finder brings you back here.

Study design
24 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 24 sample titles: 24 distinct titles with little repetition. 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.
