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 23 patients with IPF or related disorders were obtained from the Lung Tissue Research Consortium (www.ltrcpublic.org). 11 samples came from patients who had been diagnosed with usual interstitial pneumonia/ idiopathic pulmonary fibrosis (UIP/IPF), 5 samples came from patients with non-specific interstitial pneumonia (NSIP), the remaining from patients with uncharacterized fibrosis and from patients with other ILD variants. B. 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.

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.

Project description:Pulmonary fibrosis develops as a consequence of environmentally induced lung injury and/or an inherent disease susceptibility causing fibroblast activation, proliferation and extracellular matrix deposition. The study was undertaken to characterise global gene expression in pulmonary fibroblasts to better understand the mechanisms underlying the fibrotic fibroblast phenotype. Gene expression was evaluated in lung fibroblasts derived from ten controls (normal periphery of resected tumor), open lung biopsies from eight patients with interstitial lung disease associated with systemic sclerosis (fibrotic non specific interstitial pneumonia pattern on biopsy), and from three patients with usual interstitial pneumonia. Lung fibroblasts were grown to confluence in DMEM with 10% fetal calf serum. At confluence, lung fibroblasts were serum-deprived for 44 hours in the presence of fibroblast growth medium with the addition of 0.1% bovine serum albumin (Sigma).

Project description:The response to a 4 hour treatment with TGFbeta (4 ng/ml) was evaluated in lung fibroblasts derived from three controls (normal periphery of resected tumor), open lung biopsies from three patients with idiopathic pulmonary fibrosis (usual interstitial pneumonia pattern on biopsy) and from three patients with fibrosing alveolitis associated with systemic sclerosis (fibrotic non specific interstitial pneumonia pattern on biopsy). Lung fibroblasts were grown to confluence in DMEM with 10% fetal calf serum. At confluence, lung fibroblasts were serum-deprived overnight, and exposed to either 4 ng/ml of activated TGF-Ã1 (R&D Systems) or serum-free culture medium with 0.1% BSA for four hours.

Project description:Rationale: Idiopathic interstitial pneumonia (IIP) and its’ familial variants are progressive and largely untreatable disorders with poorly understood molecular mechanisms. Both the genetics and the histologic type of IIP play a role in understanding the etiology and pathogenesis of interstitial lung disease, but transcriptional signatures of these subtypes are unknown. Objectives: To evaluate gene expression in the lung tissue from patients with usual interstitial pneumonia (UIP) and non-specific interstitial pneumonia (NSIP) that were either familial or non-familial in origin and compare them to gene expression from normal lung parenchyma. Methods: We profiled RNA from lungs of 16 patients with sporadic IIP, 10 with familial IIP, and 9 normal controls on a whole human genome oligonucleotide microarray. Results: Significant transcriptional differences exist in familial and sporadic IIPs. The genes distinguishing the genetic subtypes belong to the same functional categories as transcripts that distinguish IIP from normal samples. Relevant categories include chemokines and growth factors and their receptors, complement components, genes associated with cell proliferation and death, and genes in the Wnt pathway.
