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
32 samples: 8 conditions, mostly with about 4 replicates eachGroups 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.

KAT6B overexpression in mice causes aggression, anxiety, and epilepsyiScience · 2025
Summary (written by the submitters)
High histone acetylation is associated with high transcriptional activity. The lysine acetyltransferase KAT6B is known to be required for histone acetylation and KAT6B is essential for normal brain development. In this study we examined the effects of loss and gain of KAT6B on gene expression in the developing cerebral cortex. We isolated RNA from the dorsal telencephalon of embryonic day 12.5 embryos, which is the primordium of the cerebral cortex, and from the E15.5 foetal cortex of mouse embryos and foetuses that lacked KAT6B or overexpressed KAT6B.

Genes required for brain development and neuronal differentiation were downregulated in Kat6b null tissues and upregulated in Kat6b transgenic overexpressing tissue.

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 GSE280784_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.

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.

Supports a between-group comparison across 32 samples.

How we read this: 8 replicated groups read from 32 sample titles; they account for 32 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.
