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.

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)
EZH2 is a key epigenetic regulator that catalyzes histone methylation to effect transcriptional repression. Preliminary data suggested that EZH2 induction is a protective response mounted by the brain in response to seizures. To investigate the impact of EZH2 deletion in hippocampal neurons under pathological conditions, we generated whole transcriptome profiles using RNA sequencing in saline and kainate-treated wild-type (EZH2nWT) mice, as well as homozygous EZH2 neuronal knockout (EZH2nHom) mice.

Our results reveal significant alterations in gene expression patterns in the hippocampus of EZH2nHom compared to EZH2nWT mice, particularly following kainate-induced seizures. Overall, our study provides valuable insights into the transcriptional changes induced by EZH2 deletion in hippocampal neurons, highlighting its importance in regulating gene expression in response to epileptogenic insults.

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.

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE268679_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.

Supports a case/control comparison: 9 samples read as cases, 10 as controls.

How we read this: 4 replicated groups read from 19 sample titles; they account for 19 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.
