Summary (written by the submitters)
The physiology of trabecular meshwork (TM) controls aqueous humor outflow resistance and thereby intraocular pressure (IOP), a major risk factor for primary open-angle glaucoma (POAG). To decipher how GWAS-identified non-coding variants contribute to IOP and POAG, we generated a high-resolution map of genome topology and regulatory modules from primary human TM cell lines.
Read the full summary ↓
Integrated analyses with dexamethasone-treated TM cells, a model of augmented IOP, demonstrate extensive changes in chromatin compartments, accessibility, looping, and histone marks that are highly concordant with transcriptional changes. By combining GWAS-associated variants with dexamethasone-induced chromatin looping, we discovered 26 IOP- and 52 POAG- candidate causal genes, belonging to key TM pathways, including integrin, transcriptional regulation of VENTX, and TNF signaling. Our studies provide a mechanistic framework for elucidating genetic complexity of IOP and pathogenesis of POAG and suggest new targets for therapies.

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 GSE301516_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 PRJNA1285380 and SRA study SRP597556. Searching any of these in the dataset finder brings you back here.

Study design
3 × Resource ATAC TM62 vs 3 × Resource ATAC TM71 vs 2 × Control ATAC TM62 vs 2 × Dexamethasone-treated ATAC TM62

Supports a case/control comparison: 3 samples read as cases, 3 as controls.

How we read this: 4 replicated groups read from 12 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.
