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
8 samples: 2 × WT parental, untreated, vs 2 × WT parental, TGFB treated, vs 2 × AGPS KO, untreated, vs 2 × AGPS KO, TGFB treated,Groups 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 investigates the transcriptional changes associated with depleting ether lipids via AGPS (alkylglycerone phosphate synthase) knockout in epithelial PyMT-1099 murine breast cancer cells. RNA-Seq was performed to compare the gene expression profiles between AGPS knockout and control cells, both in the presence and absence of TGF-B treatment. The data provide insights into how ether lipid metabolism intersects with TGF-B-mediated signaling pathways and epithelial-to-mesenchymal transition (EMT) in breast cancer.

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 GSE300281_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 PRJNA1280027 and SRA study SRP593346. Searching any of these in the dataset finder brings you back here.

Study design
2 × WT parental, untreated, vs 2 × WT parental, TGFB treated, vs 2 × AGPS KO, untreated, vs 2 × AGPS KO, TGFB treated,

Supports a between-group comparison across 8 samples.

How we read this: 4 replicated groups read from 8 sample titles; they account for 8 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.
