Single-nucleus RNA-seq · mouse · 12 samples

What it is
Single-nucleus RNA-seqGene activity measured in individual nuclei (used when whole cells are hard to isolate, for example from frozen tissue). Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.
Organism
Mus musculus (mouse)
Samples
12 samples: 4 × Male P0 vs 4 × Male P14 vs 4 × Male P28Groups 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)
Transcription is regulated in part through histone proteins that complex with DNA and control access to genes. Histones can be replaced with variant forms that are particularly critical in the brain and accumulate throughout lifespan. Recently, we defined the first broadly expressed H2B variant, H2BE, and demonstrated that it regulates chromatin structure, neuronal transcription, and mouse behavior.

However, the role of H2BE in other cell types and its role throughout lifespan remain unknown. Here, we discovered that H2BE is highly expressed in astrocytes as well as neurons and accumulates with age in both cell types. Using single-nucleus RNA-sequencing, we demonstrate that loss of H2BE robustly affects gene expression in both astrocytes and neurons, with divergent effects in young and aging brains. Interestingly, loss of H2BE in young brains causes similar gene expression changes as aging and some effects of aging are reversed with H2BE loss. Lastly, behavioral testing demonstrates that H2BE loss disrupts long-term memory but improves working memory in aging mice. Together, these data provide novel links between histone variants, aging-related gene expression changes in both astrocytes and neurons, and memory.

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 GSE282467_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: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1188837 and SRA study SRP546649. Searching any of these in the dataset finder brings you back here.

Study design
4 × Male P0 vs 4 × Male P14 vs 4 × Male P28

Supports a between-group comparison across 12 samples.

How we read this: 3 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.
