Summary (written by the submitters)
Accurate DNA replication is essential for genome integrity, with dysregulated replication dynamics, replication stress and genomic instability-hallmarks of cancer and aging. Here, we identify NAT10-mediated β-hydroxybutyrylation (Kbhb) of histones that safeguards replication fork progression, alleviates replication stress, and preserves genomic stability.
Read the full summary ↓
DNA fiber analyses show β-hydroxybutyrate (BHB) treatment enhances replication efficiency while maintaining fork symmetry, effects abolished by NAT10 depletion or inhibition. BrdU/EdU labeling, FACS analyses reveal that NAT10-mediated Kbhb accelerates replication fork velocity and shortens S-phase duration. LC-MS/MS profiling shows no significant changes in origin firing following BHB treatment. Mechanistically, NAT10-mediated Kbhb modulates chromatin association, thereby modulating chromatin accessibility to establish a replication-permissive environment. This epigenetic remodeling mitigates replication stress markers and genomic instability. Conserved effects in transformed and primary cell models position NAT10 as a metabolic-epigenetic nexus linking nutrient signaling to replication fidelity. Our findings suggest targeting Kbhb signaling as a potential therapeutic strategy against replication stress-associated pathologies.

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 GSE292952_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 PRJNA1242228 and SRA study SRP573434. Searching any of these in the dataset finder brings you back here.

Study design
3 × A vs 3 × B vs 3 × C vs 3 × D

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 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.
