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
12 samples: 6 × WT 4T1 cells-bearing tumo vs 6 × Tn 4T1 cells-bearing tumoGroups 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)
Aberrant O-glycosylation and accumulation of the Tn antigen are associated with aggressive phenotypes in triple-negative breast cancer (TNBC). To investigate the transcriptomic consequences of Tn antigen expression, we analyzed gene expression profiles of murine 4T1 breast cancer cells carrying CRISPR/Cas9-mediated silencing of the Cosmc gene (Tn+) compared with parental wild-type 4T1 cells (WT). Total RNA was extracted from 4T1 cells-bearing tumors from mice (Tn and WT)s and subjected to RNA sequencing using Illumina NovaSeq X technology.

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 GSE332663_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 PRJNA1468737 and SRA study SRP702453. Searching any of these in the dataset finder brings you back here.

Study design
6 × WT 4T1 cells-bearing tumo vs 6 × Tn 4T1 cells-bearing tumo

Supports a between-group comparison across 12 samples.

How we read this: 2 replicated groups read from 12 sample titles; they account for 12 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.
