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: 6 × WT Normoxia vs 5 × VIPKO Hypoxia vs 4 × WT Hypoxia vs 4 × VIPKO NormoxiaGroups 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)
We earlier reported spontaneous moderate pulmonary arterial hypertension in Vasoactive Intestinal Peptide (VIP) gene knockout mice. In the current study, we show accelerated pulmonary artery pressure changes associated with vascular and cardiac remodeling changes in VIP KO mice subjected to hypoxia compared to control wild-type C57BL/6 mice in hypoxia chambers.
Read the full summary ↓
There is differential whole-lung RNA sequencing expression between baseline normoxia wild-type and VIP KO mice groups. Under conditions of hypoxia vs. normoxia, we observe upregulation of spatial biology expression of CD45 in VIP KO mice with hypoxia, but not in wild-type mice with hypoxia. Moreover, wild-type hypoxia mice express alpha-actin and CD31, which is not seen in the VIP KO hypoxia cohort. Human lung tissue from pediatric patients with idiopathic pulmonary arterial hypertension (PAH) lacks immunohistochemical evidence of VIP, supporting the concepts that VIP plays a critical role in the immunopathogenesis of pulmonary hypertension and VIP or its analogues may potentially be used to treat PAH.

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 GSE315475_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 PRJNA1397210 and SRA study SRP659397. Searching any of these in the dataset finder brings you back here.

Study design
6 × WT Normoxia vs 5 × VIPKO Hypoxia vs 4 × WT Hypoxia vs 4 × VIPKO Normoxia

Supports a between-group comparison across 19 samples.

How we read this: 4 replicated groups read from 20 sample titles; they account for 19 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.
