Paper
RACK7 Interacts with PRC2 Complex to Regulate Astrocyte DevelopmentAdvanced science (Weinheim, Baden-Wurttemberg, Germany) · 2025
Summary (written by the submitters)
Dysregulation of epigenetic mechanisms play crucial roles in brain development and disease. Emerging evidence suggests that RACK7, an epigenetic reader protein, may play a role in brain development, but in vivo exploration of RACK7 in neural development and the underlying mechanisms are still lacking. Here, we established a conditional knock-out Rack7 mouse model and show that Rack7-deficient mice exhibit overt developmental defects.

Multicomplex immunofluorescence staining (mIF) of cell-type specific markers indicates that the developmental defects are associated with compromised astrocyte development. Mechanistically, we surprisingly found RACK7 interacts with PRC2 complex, which acts as the histone H3K27 methyltransferase. Our results suggest RACK7 binding with PRC2 complex helps to establish the proper genomic location of histone H3K27me3 modification. Deletion of Rack7 in astrocyte leads to a remarkable decrease of H3K27me3 chromatin enrichment. genome-wide?. Functionally, we found RACK7 works together with H3K27me3 to prevent overactivation of Wnt signaling pathway and other astrocyte differentiation genes. Collectively, our study provides new insights into the cellular and molecular mechanisms underlying brain development regulated by RACK7.

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 GSE270581_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1127522 and SRA study SRP515896. Searching any of these in the dataset finder brings you back here.

Study design
24 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 24 sample titles: 24 distinct titles with little repetition. 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.
