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
15 samples: 5 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.

A Plastic EMP1+ to LGR5+ Cell State Conversion as a Bypass to KRASG12D Pharmacologic Inhibition in Metastatic Colorectal CancerCancer discovery · 2026
Summary (written by the submitters)
Inhibitors of the oncogene KRAS holds promise for treating metastatic CRC (mCRC). Here we show that the activity of a small molecule RAS inhibitor, RM-044, which covalently binds to the G12D mutation in the active (ON) conformation of RAS, demonstrated strong curative effects in CRC models of early liver metastases, but its therapeutic activity was diminished in the advanced metastatic disease.
Read the full summary ↓
RM-044-treated metastases underwent a fast transition from a poor-prognosis-associated Emp1⁺ transcriptional cell state to a WNT-driven Lgr5⁺ stem cell-like state that supported tumor growth in the absence of RAS G12D activity. This plastic conversion involved a switch in transcription factor usage, and did not require extensive chromatin remodeling. Enforced conversion of metastatic cells to the Lgr5⁺ state via RAS G12D inhibition, followed by genetic ablation of this population, produced strong therapeutic effects. Overall, these findings demonstrate a central role for oncogenic KRAS in governing cellular plasticity in mCRC.

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 GSE294822_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.

How we read this: 5 replicated groups read from 15 sample titles; they account for 15 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.
