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
24 samples: 10 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)
Genes encoding subunits of the BAF (mammalian SWI/SNF) ATP-dependent chromatin remodeling complex are among the those most enriched for deleterious de novo mutations in intellectual disabilities and autism spectrum disorder, but the causative molecular pathways are not understood. Synaptic activity in neurons is critical for learning and memory and proper neural development.
Read the full summary ↓
While BAF is required for activity-dependent developmental processes, such as dendritic outgrowth, the immediate molecular consequences of neuronal activity on BAF complexes are unknown. Here we report that neuronal activity induces dramatic remodeling of the subunit composition of BAF complexes within 15 minutes, concurrent with both phosphorylation and dephosphorylation of its subunits. These biochemical effects are a convergent phenomenon downstream of multiple calcium-activated signaling pathways in neurons and fibroblasts and correspond to changes in BAF-dependent chromatin accessibility. Our studies imply that BAF decodes signals at the membrane by altering the combinatorial composition of its subunits.

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 GSE245251_RAW.tar (it can run to tens of gigabytes).

All supplementary files ↗ Whole study · RAW.tar ↓
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.

Raw reads on ENA ↗

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 PRJNA1027473 and SRA study SRP466059. Searching any of these in the dataset finder brings you back here.

Supports a case/control comparison: 5 samples read as cases, 2 as controls.

How we read this: 10 replicated groups read from 24 sample titles; they account for 24 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.
