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.
Paper
A conserved BAH module within mammalian BAHD1 connects H3K27me3 to Polycomb gene silencingNucleic acids research · 2021
Summary (written by the submitters)
Trimethylation of histone H3 lysine 27 (H3K27me3) is crucially involved for gene silencing, (epi)genome organization, cell-fate decision-making and development. To date, functional readout of H3K27me3 is viewed to be achieved mainly through a class of H3K27me3-recognizing chromodomains harbored within the chromobox (CBX) subunit of Polycomb repressive complex 1 (PRC1), which causes chromatin compaction and gene repression partly through histone H2A lysine 119 mono-ubiquitination.

We here report that engagement of H3K27me3 by an evolutionarily conserved bromo adjacent homology (BAH) domain harbored within BAH-containing protein 1 (BAHD1) significantly contributes to optimal repression of the H3K27me3-demarcated genes in mammalian cells. BAHD1 assembles a NurD-like transcriptional corepressor complex that contains histone deacetylase 1/2 (HDAC1/2) and MIER1/2/3. Abolishing the BAHD1BAH:H3K27me3 interaction by point mutagenesis interferes with BAHD1 binding to chromatin, resulting in chromatin remodeling at target genes and derepression of Polycomb-related genes. Mice carrying an H3K27me3-association-defective mutation at Bahd1BAH causes marked embryonic lethality, indicating a requirement of this pathway for development. Altogether, this work demonstrates an H3K27me3-initiated signaling cascade that operates through a conserved BAH ‘reader’ module class in mammals.

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 GSE160057_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 PRJNA671707 and SRA study SRP288497. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 12 samples.

How we read this: 6 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.
