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.

44 samples: 16 conditions, mostly in triplicateGroups 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.

The Intellectual Disability Risk Gene Kdm5b Regulates Long-Term Memory Consolidation in the HippocampusThe Journal of neuroscience : the official journal of the Society for Neuroscience · 2024
Summary (written by the submitters)
The histone lysine demethylase KDM5B has been implicated in recessive intellectual disability disorders and heterozygous, protein truncating variants in KDM5B are associated with reduced cognitive function in the normal adult population. To help distinguish between developmental and demethylase-dependent functions of KDM5B in hippocampus-dependent learning and memory, we studied mice homozygous for a Kdm5bDARID allele that lacks demethylase activity.
Read the full summary ↓
Demethylase-deficient Kdm5bDARID/DARID mice exhibited hyperactivity and long-term memory deficits in hippocampus-dependent learning tasks. The expression of immediate early, activity-dependent genes was downregulated in mice in the home cage (baseline) and hyperactivated upon learning stimulus compared to wildtype mice. The expression of other learning-associated genes was also significantly altered in the Kdm5bDARID/DARID hippocampus. These findings identify KDM5B as a critical regulator of gene expression and synaptic plasticity in the adult hippocampus and suggest that at least some of the cognitive phenotypes associated with KDM5B gene variants are caused by direct effects on learning and memory mechanisms.

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 GSE240887_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 PRJNA1005646 and SRA study SRP455234. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 44 samples.

How we read this: 16 replicated groups read from 44 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.
