Summary (written by the submitters)
The mechano-responsiveness of osteocytes is critical for maintaining bone health, yet the molecular mechanisms underlying this process remain poorly understood. Here, we investigate the impact of mechanical loading on transcriptional and epigenetic remodeling in osteocytes. Using MLO-Y4 cells, we subjected osteocytes to mechanical loading and profiled their transcriptome and histone modifications.

Our findings revealed significant transcriptional and epigenetic changes, with NRF2 emerging as a key regulator. We demonstrated that mechanical loading stabilizes NRF2 protein levels and promotes its nucleus translocation, leading to enhanced genomic binding of NRF2 and activation of its target genes. Further analysis confirmed cell type-specific functions of NRF2, with distinct binding profiles in osteocytes compared to astrocytes. These results highlight the pivotal role of NRF2 in the mechano-responsiveness of osteocytes. Unlike pharmacologic agents that stabilize NRF2, mechanical loading uniquely promoted NRF2 nucleus translocation and transcriptional activity. This underscores the irreplaceable role of mechanical stimuli, such as exercise, in promoting bone health. This study advances our understanding of osteocyte mechanotransduction and identifies potential therapeutic interventions for bone diseases.

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 GSE273535_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 PRJNA1142069 and SRA study SRP523240. Searching any of these in the dataset finder brings you back here.

Study design
11 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 11 sample titles: 11 distinct titles with little repetition. 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.
