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
20 samples: 5 × articular chondrocytes, Control vs 5 × articular chondrocytes, 25HC vs 5 × articular chondrocytes, 25HC3S vs 5 × articular chondrocytes, GW3965Groups 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)
Previous studies have demonstrated that 25-hydroxycholesterol (25HC), which is involved in the initiation and progression of osteoarthritis (OA), can be sulfated by SULT2B1 to produce 25-hydroxycholesterol-3-sulfate (25HC3S). Given this background, this study aims to investigate whether 25HC3S and 25HC have different functional effects on articular chondrocytes.

Additionally, since 25HC has been proven to be an endogenous ligand of liver X receptor (LXR), this study also compares the effects elicited by the LXR agonist GW3965 on articular chondrocytes to provide insights into whether 25HC and its sulfated derivative, 25HC3S, exert distinct influences on the LXR signaling pathway.

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 GSE283360_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 PRJNA1193519 and SRA study SRP549008. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 20 samples.

How we read this: 4 replicated groups read from 20 sample titles; they account for 20 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.
