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
10 samples: 5 × DMSO, 2wk, vs 5 × SR1815, 2wk,Groups 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.
Summary (written by the submitters)
Proximity labeling traditionally identifies interactomes of a single protein or RNA, though this approach limits mechanistic understanding of biomolecules functioning within complex systems. Here, we demonstrate a strategy for deciphering ligand-induced changes to global biomolecular interactions by enabling proximity labelling at the mesoscale, across an entire cellular system.
Read the full summary ↓
By inserting nanoscale proximity labelling catalysts throughout chromatin, this system, MesoMap, provided new insights into how HDAC inhibitors regulate gene expression. Furthermore, it revealed that the orphaned drug candidate, SR-1815, regulates disease-linked Syngap1 gene expression through direct inhibition of kinases implicated in both neurological disorders and cancer. Through precise mapping of global chromatin mobility, MesoMap promotes insights into how drug-like chemical probes induce transcriptional dynamics within healthy and disease-associated cellular states.

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 GSE304412_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 PRJNA1301262 and SRA study SRP606460. Searching any of these in the dataset finder brings you back here.

Study design
5 × DMSO, 2wk, vs 5 × SR1815, 2wk,

Supports a between-group comparison across 10 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 10 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.
