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)
Topic
Colorectal cancerThis series is part of our curated briefing on it.
Samples
67 samples: 5 conditions, mostly with about 35 replicates eachGroups 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.

Summary (written by the submitters)
This study aims to determine the efficacy, safety, and tolerability of the sequential addition of immune-modulating therapy to standard-of-care therapy of microsatellite-stable (MSS)/mismatch repair-proficient (pMMR) metastatic colorectal cancer (mCRC). Patients with MSS/pMMR-mCRC harbor tumor that can be transformed into an immunogenic disease by short-course oxaliplatin-based therapy, and may thereby benefit from the addition of immune-modulating therapy to improve outcome of the current oxaliplatin-based standard-of-care.

Primary objective: To determine progression-free survival (PFS), in terms of failure of treatment strategy, of sequential treatment with the Nordic FLOX (5-Fluorouracil, oxaliplatin and leucovorin) regimen and nivolumab compared with the standard-of-care Nordic FLOX regimen in previously untreated MSS/pMMR-mCRC. Secondary objectives: To determine safety and tolerability of sequential treatment with the Nordic FLOX regimen and nivolumab compared with the standard-of-care Nordic FLOX regimen. To monitor and compare quality-of-life (QoL) alterations during therapy courses.

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 GSE313035_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 PRJNA1378168 and SRA study SRP654474. Searching any of these in the dataset finder brings you back here.

Study design
5 conditions, mostly with about 35 replicates each
1 ×35 4 ×15 2 ×10 3 ×4 5 ×3

Supports a between-group comparison across 67 samples.

How we read this: 5 replicated groups read from 67 sample titles; they account for 67 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.
