Paper
Nucleosome stability safeguards cell identity, stress resilience and healthy agingResearch square · 2025
Summary (written by the submitters)
Nucleosomes are the minimal repeating units of chromatin. Their dynamic assembly and disassembly underpins chromatin organization and genome regulation. However, how intrinsic nucleosome stability contributes to higher-level yet fundamental cellular and organismal properties—such as preservation of cell identity, lineage specification, stress resilience and healthy aging—remains unclear.
Read the full summary ↓
To address this, we tested the impact of intrinsic nucleosome instability across multiple cell, tissue and organismal models by introducing histone mutants that weaken histone–histone interactions. Despite no overt effects on global chromatin accessibility, DNA damage, steady-state proliferation or cell viability, nucleosome instability impaired lineage-specific gene expression programs, altered lineage specification and activated intrinsic inflammatory and stress pathways in a manner reminiscent of aging in mouse tissues and human cells. Consistently, in Caenorhabditis elegans and Drosophila melanogaster, nucleosome instability accelerated the onset of age-associated transcriptional alterations and functional decline in Caenorhabditis elegans and Drosophila melanogaster, and . At the cellular level, nucleosome instability also heightened cellular sensitivity vulnerability to exogenous perturbations—including environmental, epigenetic and mitotic stress—in human cells and Saccharomyces cerevisiaeyeast. These cross-species findings identify nucleosome stability as an evolutionarily conserved epigenetic safeguard that preserves cell identity and stress resilience, sustaining organismal function and longevity.

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 GSE307869_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.

Raw reads on ENA ↗

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 PRJNA1327445 and SRA study SRP619333. Searching any of these in the dataset finder brings you back here.
