Project description:The mechanisms and molecular pathways underlying interstitial lung diseases (ILDs) are poorly understood. Systems biology approaches were used to identify perturbed networks in these disease states to gain a better understanding of the underlying mechanisms of disease. Through profiling genes and miRNAs, we found subsets of genes and miRNAs that distinguish different disease stages, ILDs from controls, and idiopathic pulmonary fibrosis (IPF) from non-specific interstitial pneumonitis (NSIP). Traditional pathway analysis revealed several disease-associated modules involving genes from the TGF-beta, Wnt, focal adhesion and smooth muscle actin pathways that may be involved in advancing fibrosis. A comprehensively integrative approach was used to construct a global gene regulatory network based on the perturbation of key regulatory elements, transcriptional factors and miRNAs. The data also demonstrated that several subnetworks were significantly associated with key molecules involved in the diseases. We present a broad overview of the disease at a molecular level and discuss several possibly key regulatory molecular circuits that could play central roles in facilitating the progression of ILDs. Lung tissue samples from thirty patients with IPF or related disorders were obtained from the Lung Tissue Research Consortium (www.ltrcpublic.org). Ten samples came from patients who had been diagnosed with usual interstitial pneumonia/ idiopathic pulmonary fibrosis (UIP/IPF), nine samples came from patients with non-specific interstitial pneumonia (NSIP), four from patients with uncharacterized fibrosis, and the remaining samples came from patients with other ILD variants. Biopsies from uninvolved lung tissue from lung cancer patients (5 samples) and from one lung transplant patient were used as controls for comparison with the ILD samples.

Project description:PBC RNA samples from 134 baseline and 98 month-12 visits, corresponding to the active treatment period of both arms in Scleroderma Lung Study II, along with 45 healthy controls were investigated by global RNA sequencing. The objective was to examine the peripheral blood cell (PBC) gene expression changes ensuing from mycophenolate mofetil (MMF) or cyclophosphamide (CYC) treatment and to determine the predictive significance of baseline PBC transcript scores for response to immunosuppression in systemic sclerosis (SSc) related interstitial lung disease (ILD).

Project description:We identified eighty two skin transcripts significantly correlated with the severity of interstitial lung disease (ILD) in systemic sclerosis. These genes separated patients with more sever ILD in unsupervised hierarchical clustering. Pathway analysis revealed pathways involved in extravasation and adhesion of inflammatory cells to endothelium. Skin biopsy samples from 59 patients enrolled in the GENISOS cohort or an open label imatinib study were examined by global gene expression studies.
