Paper
Histone lactylation in macrophages is predictive for gene expression changes during ischemia induced-muscle regenerationMolecular metabolism · 2024
Summary (written by the submitters)
After injury, muscles require fully functional macrophages to recover completely. During muscle regeneration, macrophages transition from a pro-inflammatory to a pro-restorative phenotype ensures the proper regeneration. Lactate is a crucial molecule for muscle-residing macrophage polarisation. Histone lactylation, a direct derivative of lactate, has been implicated in macrophage polarisation in vitro .

In this work, we show for the first time that macrophages recruited to the muscle after ischemic injury modify their histone lactylome between 2 and 4 days post injury. Absolute histone lactylation levels increase significantly. Although subtly, also the genomic enrichment of H3K18la changes from 2 to 4 days post injury and this correlates with gene expression changes. Interestingly, we find that H3K18la genomic enrichment changes from day 2 to day 4 post injury are predictive for gene expression changes later in time, from day 4 to day 7, rather than being a reflection of past gene expression changes from day 1 to day 2. Our results suggest that histone lactylation dynamics are functionally important for the resolving action of macrophages during muscle regeneration.

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 GSE254129_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 PRJNA1068610 and SRA study SRP485735. Searching any of these in the dataset finder brings you back here.
