TWIST1 mediated transcriptional activation of SPON2 drives colorectal cancer peritoneal metastasis through stromal cell signaling networkOncogene · 2026
Summary (written by the submitters)
Colorectal cancer (CRC) peritoneal metastasis (PM) accounts for 25–35% of stage IV cases. CRC PM carries a median overall survival of 16 months with systemic chemotherapy and an almost 0% five-year survival rate. The molecular mechanisms driving CRC PM remain poorly defined. CRC heterogeneity is classified into four Consensus Molecular Subtypes (CMS1-4), with CRC PM predominantly exhibiting the CMS4 signature—characterized by increased stromal/mesenchymal enrichment and cellular plasticity—features linked to frequent disease progression and therapeutic resistance.

Here, we investigated the molecular mechanisms driving CRC PM and CMS4 signature. TWIST1 was identified to be significantly upregulated in CRC PM. We established TWIST1-SPON2 as a novel transcriptional axis contributing to CRC PM tumorigenesis, through mediating tumor-stroma interactions. We identified SPP1, secreted by the tumor stroma, as an upstream regulator of the TWIST1-SPON2 cascade via AKT activation in tumor cells in vitro and in vivo. This defined SPP1-TWIST1-SPON2 signaling circuit is pivotal in shaping the tumor microenvironment and promoting CRC PM progression. The findings establish the SPP1-TWIST1-SPON2 axis as potential biomarkers and therapeutic targets in CRC PM.

This dataset
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 GSE319741_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 PRJNA1425037 and SRA study SRP677807. Searching any of these in the dataset finder brings you back here.

Study design
28 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 28 sample titles: 28 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.
