Paper
The DNA loop release factor WAPL suppresses Epstein-Barr virus latent membrane protein expression to maintain the highly restricted latency I programPLoS pathogens · 2024
Summary (written by the submitters)
Epstein-Barr virus (EBV) is a ubiquitous human pathogen that is etiologically linked to several cancers and has been connected to multiple sclerosis. EBV persists in its human hosts through a biphasic replication cycle that depends on three latency stages. Understanding the host mechanisms that contribute to the tight regulation of viral gene expression in the discrete states of latency III, latency II, and latency I is important for developing therapeutic approaches for treating EBV positive cancers.

Regulation of the chromatin structure of the EBV genome by cohesin and CTCF plays a role in this latency type switching. However, the function of the cohesin release factor WAPL had not previously been understood. In this study, we employ RNA-seq combined with immunofluorescence analysis to determine that the cohesin release factor WAPL plays a role specifically in inhibiting the expression of the oncogenic latent membrane proteins LMP-1 and LMP-2A. Through a combination of Hi-ChIP and ChIP-qPCR, we uncover that WAPL loss alters the looping interactions within the EBV genome and alters the histone modifications present at the LMP promoter. We propose that EBV coopts WAPL to maintain a latency I state and, without WAPL, leaky expression of the LMP proteins occurs.

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 GSE248336_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 PRJNA1043233 and SRA study SRP473130. Searching any of these in the dataset finder brings you back here.
