Summary (written by the submitters)
Fibrotic diseases impose a major socioeconomic challenge on modern societies with limited treatment options. Adropin, a peptide hormone encoded by the energy-homeostasis-associated (ENHO) gene, is implicated in metabolism and vascular homeostasis, but its role in the pathogenesis of fibrosis remains enigmatic. Here, we used machine learning approaches in combination with functional in vitro and in vivo experiments to characterize Adropin/ENHO as a potential regulator involved in fibroblast activation and tissue fibrosis in systemic sclerosis (SSc).

We demonstrated consistent downregulation of Adropin/ENHO in SSc skin across different SSc cohorts. The prototypical profibrotic cytokine TGFβ reduced Adropin/ENHO expression in a JNK-dependent manner. Restoration of Adropin signaling by therapeutic application of bioactive Adropin34-76 peptides in turn inhibited TGFβ-induced fibroblast activation and fibrotic tissue remodeling in primary human dermal fibroblasts, three-dimensional full-thickness skin equivalents, the mouse models of bleomycin-induced pulmonary fibrosis and sclerodermatous chronic graft-versus-host-disease (sclGvHD), and precision-cut human skin slices (PCSS). Knockdown of GPR19, receptor of Adropin, abrogated the antifibrotic effects of Adropin in fibroblasts. RNA-seq demonstrated that the antifibrotic effects of Adropin34-76 were functionally linked to deactivation of GLI1 dependent profibrotic transcriptional networks, which was experimentally confirmed in vitro, in vivo and ex vivo. ChIP-seq confirmed Adropin34-76-induced changes in TGFβ/GLI1 signaling. Our study thus characterizes the TGFβ-induced downregulation of Adropin/ENHO expression as a potential pathomechanism of SSc as a prototypical systemic fibrotic disease that unleashes uncontrolled activation of profibrotic GLI1 signaling. We also provide evidence in multiple preclinical models that Adropin34-76 might offer potential for the treatment of fibrosis.

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 GSE252139_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 PRJNA1057863 and SRA study SRP480351. Searching any of these in the dataset finder brings you back here.

Study design
3 × C vs 3 × T vs 3 × AT vs 3 × Input

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.
