Paper
Long-term DNA methylation changes induced by age and elevated CO(2) in skeletal muscleSkeletal muscle · 2025
Summary (written by the submitters)
Skeletal muscle dysfunction and elevated CO2 in the blood, or hypercapnia, are both associated with higher mortality in acute and chronic pulmonary diseases. Hypercapnia causes accelerated protein degradation, reduced protein synthesis, and dysfunctional myogenesis. We have recently reported that hypercapnia-induced skeletal myogenic dysfunction persists after resolution of CO2 exposure, suggesting the existence of durable cellular aberrations in previously hypercapnic cells.
Read the full summary ↓
No data on lingering myofiber atrophy after hypercapnia resolution currently exist. Hypercapnia and age-induced skeletal muscle loss phenotypically overlap, and myogenic progenitor cells from hypercapnic mice elicit senescence-associated transcriptional programs. While aging is characterized by unique DNA methylation and other epigenetic changes, the potential association of hypercapnia and age-related differential methylation have never been investigated. In the present study, we show that hypercapnic mice elicit protracted muscle deterioration even after returning to normocapnia and demonstrate aberrant DNA methylation in comparison to animals never exposed to elevated CO2. We also show that these DNA methylation changes do not overlap with age-induced alterations.

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 GSE297286_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 beta-value tables or raw IDAT files among the supplementary files.

Also filed as BioProject PRJNA1263460 and SRA study SRP585565. Searching any of these in the dataset finder brings you back here.
