Single-nucleus RNA-seq · human · 72 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
Homo sapiens (human)
Samples
72 samples: 22 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)
Half of all amyotrophic lateral sclerosis (ALS) patients demonstrate a spectrum of cognitive and behavioral changes over the course of the disease, but the mechanisms underlying this heterogeneity remain unclear. We assemble a high-resolution cellular map of prefrontal cortex regions of the ALS brain by integrating spatial and single-nucleus transcriptomic profiles of a cognitively stratified ALS patient cohort that includes non-neuropathological controls.
Read the full summary ↓
We find cellular programs characteristic of ALS, including a frequent gliotic response. We also find that executive and language cognitive impairments differ from ALS without cognitive impairment, and from each other, in the extent and pattern of neuronal dysregulation and neuron-glial interactions across different brain regions. These findings reveal a relationship between cognitive phenotype and prefrontal cortex dysfunction in ALS.

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 GSE314526_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: 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 PRJNA1391459 and SRA study SRP659828. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 44 samples.

How we read this: 22 replicated groups read from 72 sample titles; they account for 44 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.
