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
84 samples: 42 conditions, mostly in duplicateGroups 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 epidemiological research suggests that maternal immune activation (MIA) during early pregnancy is a significant risk factor for neurodevelopmental and psychiatric disorders in offspring. Epigenetic factors and chromatin-related phenomena remain largely plastic during the course of prenatal and early postnatal development, allowing a dynamic impact of environmental effects on access to genes and regulatory elements.

In this study, we tested the effects of maternal infection with the mouse-adapted influenza A/WSN/33 (H1N1) virus as a MIA model. Additionally, to assess the prenatal and postnatal effects of MIA, we cross-fostered half of the neonatal mice immediately after birth.This study includes RNA-seq and ChIP-seq profiling (H3K27ac, H3K4me3) from the prefrontal cortex of MIA-exposed and control mice. RNA-seq and ChIP-seq data are submitted under separate Series and linked via sample annotations.

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 GSE297245_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 PRJNA1263387 and SRA study SRP585644. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 84 samples.

How we read this: 42 replicated groups read from 84 sample titles; they account for 84 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.
