Project description:Objective: MicroRNAs (miRNAs) control key elements of mRNA stability and likely contribute to the dysregulated lung gene expression observed in systemic sclerosis associated interstitial lung disease (SSc-ILD). We analyzed the miRNA gene expression of tissue and cells from SSc-ILD patients. A chronic lung fibrotic murine model was used. Methods: RNA was isolated from lung tissue of 12 SSc-ILD patients and 5 control lungs. High-resolution computed tomography (HRCT) was performed at baseline and 2-3 years after treatment. Lung fibroblasts and PBMCs were isolated from healthy controls and SSc-ILD patients. miRNA and mRNA were analyzed by microarray, quantitative polymerase chain reaction, and/or Nanostring; pathway analysis was performed by DIANA-miRPath v2.0 software. Wild-type and miR-155 deficient (miR-155ko) mice were exposed to bleomycin. Results: Lung miRNA microarray data distinguished patients with SSc-ILD from healthy controls with 185 miRNA differentially expressed (q<0.25). DIANA-miRPath revealed 57 KEGGs pathways related to the most dysregulated miRNAs. miR-155 and miR-143 were strongly correlated with progression of the HRCT score. Lung fibroblasts showed only mild expression of miR-155/miR-21 after several stimuli. miR-155 PBMC expression strongly correlated with lung function tests in SSc-ILD. miR-155ko mice developed milder lung fibrosis, survived longer, and showed a weaker lung induction of several genes after bleomycin exposure compared to wild-type mice. Conclusions: miRNAs are dysregulated in lungs and PBMCs of SSc-ILD patients. Based on mRNA-miRNA interaction analysis and pathway tools, miRNAs may play a role in the progression of the disease. Our findings suggest that targeting miR-155 might provide a novel therapeutic strategy for SSc-ILD. Lung biopsies taken from open lung biopsy from SSc-ILD patients (n=15 samples) and from cancer free control patients (n=5) during ressection of the lung tumor.

Project description:To understand the cellular composition and transcriptional phenotype of fibrotic lung tissue we performed single-cell RNA-seq on stromal, immune, epithelial, and endothelial cell populations from human lung explants. Tissue was collected from normal control lungs, patients with idiopathic pulmonary fibrosis (IPF), and patients with systemic sclerosis associated interstitial lung disease (SSc-ILD). Using the 10X Genomics Chromium platform, we generated transcriptional profiles of approximately 200,500 cells across 4 IPF, 3 SSc-ILD and 3 normal control lungs.

Project description:There are no effective treatments or clinical response markers for systemic sclerosis (SSc). We sought to assess the potential of novel imaging biomarkers and gene expression profiling approaches in a clinical trial of the tyrosine kinase inhibitor dasatinib in SSc patients with interstitial lung disease (SSc-ILD).

Project description:There is a pressing need to identify early biomarkers of lung involvement in systemic sclerosis (SSc) to start as soon as possible antifibrotic therapy. We aimed to identify extracellular vesicle-derived microRNAs (EV-miRNAs) that are differentially expressed between SSc patients with and without interstitial lung disease (ILD) and explore their diagnostic value. Small EVs derived from plasma were isolated from 20 well-characterised SSc patients with ILD (SSc-ILD, n=10), without ILD (SSc-no ILD, n=10) and 10 matched healthy subjects (HS). Small RNA sequencing was used to identify sEV-miRNAs associated to SSc-ILD.
