Paper
Three-dimensional chromatin reorganization regulates B cell development during ageingNature cell biology · 2024
Summary (written by the submitters)
Three-dimensional (3D) organization of the genome is essential for precise patterns of gene expression required for biological processes, however its role in physiological aging is not known.Here we show that large scale chromatin re-organization distinguishes bone marrow progenitor (pro-) B cells of old mice from that of young mice.These changes result in increased interactions at the compartment level and reduced interactions within topologically associated domains

(TADs).One genomic region that transitions from compartment A to B with age contains the gene encoding Ebf1, a key regulator of normal B cell development.Genetically reducing Ebf1 recapitulates some features of old pro-B cells.TADs that are most reduced with age also harbor genes important for function and development of pro-B cells, including the immunoglobulin heavy chain (IgH) gene locus.Weaker intra-TAD interactions at IgH correlate with reduced utilization of distally located variable gene segments in VDJ recombination.Our observations implicate 3D chromatin re-organization as a major driver of pro-B cell phenotypes that impair B lymphopoiesis with age.

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 GSE214438_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 PRJNA885415 and SRA study SRP400252. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 74 samples.

How we read this: 34 replicated groups read from 76 sample titles; they account for 74 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.
