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 × GFP vs 6 × shRNAGroups 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)
Impaired β-cell function is a hallmark of type 2 diabetes (T2D), whereas, the underlying cellular signaling machineries that regulate β-cell function remain unknown. Here, we identify that the interleukin-22 receptor subunit alpha 1 (IL22RA1), known as a co-receptor for IL-22, is downregulated in human and mouse T2D β-cells. Mice with β-cell Il22ra1 knockout (Il22ra1βKO) exhibit defective insulin secretion and impaired glucose tolerance after a high-fat diet (HFD) or HFD/low-dose streptozotocin (STZ).

Mechanistically, β-cell IL22RA1 deficiency inhibits cytochrome b5 reductase 3 (CYB5R3) expression via the IL22RA1/STAT3/c-JUN axis, thereby impairing mitochondrial function and reducing β-cell identity. Overexpression of CYB5R3 reinstates mitochondrial function, β-cell identity and insulin secretion in Il22ra1βKO mice. Moreover, pharmacological activation of CYB5R3 with tetrahydroindenoindole restores insulin secretion in Il22ra1βKO mice, IL22RA1 knockdown human islets and Min6 cells. In conclusion, these findings suggest an important role of IL22RA1 in preserving β-cell function in T2D, which offers a potential therapeutic target for treating diabetes.

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 GSE281652_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 PRJNA1185161 and SRA study SRP544666. Searching any of these in the dataset finder brings you back here.

Study design
6 × GFP vs 6 × shRNA

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.
