Summary (written by the submitters)
Quiescence, a hallmark of adult neural stem cells (NSCs), is required for maintaining the NSC pool to support life-long continuous neurogenesis in the adult dentate gyrus (DG). Whether epigenetic mechanisms can maintain NSC quiescence over long term in the adult brain is not well-understood. Here we showed that adult mice with haploinsufficiency of Setd1a, a schizophrenia risk gene encoding a histone H3K4 methyltransferase, exhibited substantially enlarged DG with increased number of dentate granule cells.
Read the full summary ↓
Deletion of Setd1a specifically in quiescent NSCs in the adult DG promoted their activation and neurogenesis, which was countered by inhibition of histone demethylase LSD1. Mechanistically, RNA sequencing and CUT & RUN analyses of cultured quiescent adult NSCs revealed Setd1a deletion-induced transcriptional changes and Setd1a targets, among which down-regulation of Bhlhe40 promoted quiescent NSC activation in the adult DG. Together, our study revealed a Setd1a-dependent epigenetic mechanism that sustains NSC quiescence in the adult DG.

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 GSE250276_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 PRJNA1053286 and SRA study SRP478224. Searching any of these in the dataset finder brings you back here.
