(Submitter supplied) Analysis of Idiopathic pulmonary fibrosis (IPF) at gene expression level. The hypothesis tested in the present study was that Epigenetic mechanisms are likely to be associated with pathogenesis in IPF. To determine the DNA methylation change, and their effects on gene expression, we compared microarray data of DNA methylation and RNA expression. Results provide that among the genes whose DNA methylation status and RNA expression were both significantly altered between IPF-rapid and normal controls.

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) and non-specific interstitial pneumonia (NSIP) are the 2 most common forms of idiopathic interstitial pneumonia. Response to therapy and prognosis are remarkably different. The clinical-radiographic distinction between IPF and NSIP may be challenging. We sought to investigate the gene expression profile of IPF vs. NSIP We used microarray to identifiy the gene expression profiles in patients with IPF and NSIP, mixed IPF/NSIP histologic pattern and normal controls.

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) is a devastating disease with only three to five years of the median survival. Fibroblast proliferation is a hallmark of IPF as well as secretion of extracellular matrix proteins from fibroblasts. However, it is still uncertain how IPF fibroblasts acquire the ability to progressively proliferate. Periostin is a matricellular protein that is highly expressed in the lung tissues of IPF patients and plays a critical role in the pathogenesis of pulmonary fibrosis. more...

(Submitter supplied) Fibroblasts are the key effector cells in idiopathic pulmonary fibrosis (IPF), a chronic, progressive scarring disorder that results in impaired gas exchange and respiratory failure. Fibroblasts from IPF patients exhibit aberrant expression of multiple genes, but the DNA methylome of IPF fibroblasts has never been characterized. We utilized the HumanMethylation27 array, which assays the DNA methylation level of 27,568 CpG sites to compare the DNA methylation patterns of IPF fibroblasts (n=6) with those of nonfibrotic patient controls (n=3) and commercially available normal lung fibroblast cell lines (CCL190, CCL204, and CCL210). more...

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) and lung cancer share common risk factors, epigenetic and genetic alterations, cellular and molecular aberrations, the activation of similar signaling pathways and poor survival. The aim of this study was to examine the gene expression profiles of stromal cells from patients with IPF and lung adenocarcinoma (ADC) as well as from normal lung.

(Submitter supplied) BACKGROUND: Idiopathic Pulmonary Fibrosis (IPF) is a lethal lung disease of unknown etiology. A major limitation in transcriptomic profiling of lung tissue in IPF has been a dependence on snap-frozen fresh tissues (FF). In this project we sought to determine whether RNA-Seq could be used to identify IPF expression profiles from archived Formalin-Fixed Paraffin-Embedded (FFPE) lung fibrotic tissue. RESULTS: We isolated total RNA from 7 IPF and 5 control FFPE lung tissues (median archived time 6 years) and performed 50 bp paired-end sequencing on Illumina 2000 HiSeq. more...

(Submitter supplied) There is microscopic spatial and temporal heterogeneity of pathologic changes in idiopathic pulmonary fibrosis (IPF) lung tissue, which may relate to heterogeneity in pathophysiological mediators of disease and clinical progression. We measured gene expression in samples from lung biopsies or explants in order to assess relationships with pathological features and systemic biomarkers.

(Submitter supplied) Chronic hypersensitivity pneumonitis (CHP) is caused by an immune response to antigen inhalation and is characterized by variable histopathological and clinical features. A subset of CHP subjects have usual interstitial pneumonia and appear to be clinically similar to subjects with idiopathic pulmonary fibrosis (IPF). However, the molecular relationship between CHP and IPF is not well understood. We report an RNA-seq based transcriptomic analysis for whole lung tissues from CHP, IPF and control subjects.

(Submitter supplied) Fibroblasts from idiopathic pulmonary fibrosis (IPF) patients acquire an invasive phenotype that is essential for progressive fibrosis. The immune checkpoint ligand CD274 (PD-L1) is up-regulated on invasive lung fibroblasts, regulated by P53 and FAK signaling, and drives lung fibrosis in a humanized IPF model in mice. Targeting CD274high fibroblasts blunted invasion in vitro and attenuated fibrosis in vivo, suggesting that CD274 may be a novel therapeutic target in IPF.

(Submitter supplied) The activated fibroblast is the putative effector cell for the progressive fibrotic phenotype idiopathic pulmonary fibrosis (IPF). Recent studies investigating global gene expression differences between normal and IPF fibroblasts indicate that changes in gene expression occur in these fibroblasts in culture. Employing a technique that minimizes cellular phenotypic alterations, we characterized the global gene expression changes in pulmonary fibroblasts by comparing both cultured and non-cultured IPF and normal cells. more...

(Submitter supplied) Background: Idiopathic pulmonary fibrosis (IPF) is a fatal disease with variable outcome. Currently, there is little information whether changes in molecular pathways in the alveolar compartment of patients with IPF are indicative of disease progression. To address this question we analyzed gene expression signatures in cells obtained from bronchoalveolar lavage (BAL) of patients with IPF. Methods: BAL cells were harvested from 212 IPF patients and 20 healthy donors at the time of diagnosis. more...
