SIRT6 overexpression counteracts chromatin aging in the male murine liverNature communications · 2026
Summary (written by the submitters)
Aging is associated with detrimental changes in chromatin structure and gene expression, contributing to inflammation, metabolic decline and tissue dysfunction. SIRT6, a histone deacetylase, plays a key role in maintaining chromatin integrity and promoting longevity. Here, we show that aging leads to increased chromatin accessibility in the murine liver, accompanied by upregulation of inflammation and downregulation of metabolic pathways.

Remarkably, SIRT6 overexpression reversed these changes, reducing inflammation and enhancing metabolic function. Notably, ETS family members were enriched in regions with increased accessibility during aging, while liver-enriched transcription factors (LETFs) were enriched in regions with reduced accessibility. ChIP-seq analyses of H3K9ac and H3K56ac binding showed that H3K9ac, but not H3K56ac, is associated with increased accessibility during aging, and that SIRT6 can reverse this effect. Furthermore, AAV-mediated SIRT6 overexpression in aged mice demonstrated that SIRT6 not only slows age-related chromatin changes but can also reverse them, rejuvenating chromatin accessibility to a youthful state.

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 GSE294103_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 PRJNA1248381 and SRA study SRP577387. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 28 samples.

How we read this: 4 replicated groups read from 28 sample titles; they account for 28 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.
