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
20 samples: 5 × Week-03 Katnal2 knock-out vs 5 × Week-03 wild-type vs 5 × Week-10 Katnal2 knock-out vs 5 × Week-10 wild-typeGroups 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.
Paper
Loss of Katnal2 leads to ependymal ciliary hyperfunction and autism-related phenotypes in micePLoS biology · 2024
Summary (written by the submitters)
Autism spectrum disorders (ASD) frequently accompany macrocephaly, which could involve hydrocephalic enlargement of brain ventricles. Katnal2 is a microtubule-related protein strongly implicated in ASD. However, it remains unclear whether Katnal2 knockout (KO) in mice leads to microtubule-related cellular deficits and ASD-related phenotypes.
Read the full summary ↓
We found here that Katnal2-KO mice display social communication deficits, including excessive courtship ultrasonic vocalizations and decreased mating success. Katnal2-KO brains show age-dependent ventricular enlargements and motile ciliary deficits in ependymal cells lining ventricular walls. Katnal2-KO hippocampal neurons, surrounded by lateral ventricles, show limited blood volumes and flow and age-dependent synaptic functional deficits involving synaptic gene downregulation and ASD-like transcriptomic changes. Early postnatal Katnal2 re-expression prevents the ventricular and behavioral phenotypes in Katnal2-KO adults. These results suggest that Katnal2 critically regulates ependymal ciliary function, ventricular volume, CSF circulation, synaptic function, and social communication and that ependymal ciliopathies could underlie ASD-related macrocephaly, ventriculomegaly, and hydrocephalus

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 GSE219228_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.

Also filed as BioProject PRJNA907769 and SRA study SRP411022. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 20 samples.

How we read this: 4 replicated groups read from 20 sample titles; they account for 20 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.
