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
12 samples: 6 × Cortex_WT vs 6 × Cortex_NullGroups 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.

MeCP2 interacts with the super elongation complex to regulate transcriptionScience advances · 2025
Summary (written by the submitters)
Loss-of-function mutations in methyl-CpG binding protein 2 (MECP2) cause the neurodevelopmental disorder, Rett syndrome (RTT). The molecular mechanisms underlying MeCP2 function remain poorly understood. Here, using a MECP2 gain-of-function Drosophila model, we screened for genetic modifiers of MECP2-induced toxicity. Our approach identified several subunits of the Drosophila super elongation complex (SEC), a P-TEFb containing elongation factor that releases promoter-proximally paused RNA polymerase II (RNA pol II), as genetic interactors of MECP2.
Read the full summary ↓
MeCP2 directly interacts with AFF4, the scaffold of the SEC, and facilitates its binding on a subset of genes that regulate neuronal development and synaptic function in the mouse cortex. Furthermore, genes with reduced AFF4 binding showed reduced RNA pol II binding in their genebody and decreased RNA expression in Mecp2 null mice. Taken together, we propose that MeCP2 interacts with the SEC to facilitate the release of RNA pol II and thereby support gene expression.

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 GSE275332_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 PRJNA1150264 and SRA study SRP527637. Searching any of these in the dataset finder brings you back here.

Study design
6 × Cortex_WT vs 6 × Cortex_Null

Supports a between-group comparison across 12 samples.

How we read this: 2 replicated groups read from 12 sample titles; they account for 12 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.
