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
17 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.

Summary (written by the submitters)
Purpose: Examine differential gene expression changes in in vitro astrocytes with the administration of Shh agonist and Fgf protein vs control; Methods: Astrocytes were purified using a previously published immunopanning protocol, SAG-Shh agonist and DMSO are added into cell culture medium for 3 days, and Fgf2 and Fgf10 were added to medium respectively for 7 days, PBS treated astrocytes as controls.

RNA-seq were perfomed (Lexongen QuantSeq3'mRNA-SEQ V2 Library prep kit) on all different conditions; Results: We observed differential gene expression changes in SAG treated conditions compared to WT, but did not observe a significant number of genes changes in Fgf treated groups compared to controls.

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 GSE281480_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 PRJNA1184114 and SRA study SRP544197. Searching any of these in the dataset finder brings you back here.

Study design
5 conditions, mostly in triplicate
IPAstro_PBS ×4 IPAstro_FGF2 ×4 IPAstro_DMSO ×3 IPAstro_SAG ×3 IPAstro_FGF10 ×3

Supports a between-group comparison across 17 samples.

How we read this: 5 replicated groups read from 17 sample titles; they account for 17 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.
