(Submitter supplied) Hyaluronidases was reported to be effective in lung fibrosis therapy, and HYAL1 was found to inhibit TGF-β1 mediated cell growth in murine L929 fibroblasts, while the underlying mechanism of HYAL1 in regulating human lung fibroblasts is largely unknown. We used microarray to detail the gene expression of HYAL1 overexpression HFL-1 fibroblasts, and found significantly downregulated genes.

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) is a chronic progressive fibrotic lung disease associated with significant morbidity and mortality. We identified a combinatorial signature of 5 proteins that was sufficient to distinguish IPF patients from controls; of these proteins MMP7 and MMP1 exhibited significantly higher values in both peripheral blood concentrations and lung tissue gene expression, suggesting their role as true biomarkers. more...

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) is a progressive lethal interstitial lung disease of unkown etiology with limited effective therapies. The pathogenic mechanisms of IPF remain unkown. Emerging evidences indicate that abnormal behaviors of fibroblasts in IPF are associated with a variety of genetic alterations and aberrant reactivation of developmental signaling pathways. We compared gene expression profiles in fibrotic lung tissues from IPF patients and normal lung tissues from patients with primary spontaneous pneumothorax using cDNA microarray to examine the mechnisms involved in the pathogenesis of IPF.

(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) 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) Aberrant expression of master phenotype regulators by lung fibroblasts may play a central role in idiopathic pulmonary fibrosis (IPF). Interrogating IPF fibroblast transcriptome datasets, we identified Forkhead Box F1 (FOXF1), a DNA-binding protein required for lung development, as a candidate actor in IPF. Thus, we determined FOXF1 expression levels in fibroblasts cultured from normal or IPF lungs in vitro, and explored FOXF1 functions in these cells using transient and stable loss-of-function and gain-of-function models. more...

(Submitter supplied) Contractile and highly synthetic myofibroblasts are the key effector cells involved in excessive extracellular matrix (ECM) deposition in multiple fibrotic conditions, including idiopathic pulmonary fibrosis (IPF). In order to define the key drivers of the fibrotic response, we used laser capture microdissection to isolate RNA from myofibroblasts within fibroblastic foci and performed microarray analysis in combination with a novel eigengene approach to identify functional clusters of genes which associate with collagen gene expression.

(Submitter supplied) Phenotypic changes in lung fibroblasts are believed to contribute to the development of Idiopathic Pulmonary Fibrosis (IPF), a progressive and fatal lung disease. Long intergenic non-coding RNAs (lincRNAs) have been identified as novel regulators of gene expression and protein activity. In non-stimulated cells, we observed reduced proliferation and inflammation but no difference in the fibrotic response of IPF fibroblasts. 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) MicroRNAs (miRs) are a class of non-coding RNAs of ~22nt long that play an important role in regulating gene expression at a post-transcriptional level. Aberrant levels of miRs have been associated with profibrotic processes in idiopathic pulmonary fibrosis (IPF). However, the majority of these studies used whole IPF tissue or in vitro monocultures in which fibrosis has been artificially induced. In this study, we used laser microdissection to collect fibroblastic foci (FF), the key pathological lesion in IPF, then isolate miRs and compare their expression levels to those found in whole IPF lung tissue and/or in vitro cultured fibroblast from IPF or normal lungs. more...

(Submitter supplied) In USA, approximately 50,000 people are diagnosed with idiopathic pulmonary fibrosis (IPF) annually; and almost 40,000 of them die. IPF is a condition in which an injury to the lung leads to accumulation of scar tissue. This fibrotic tissue impairs the lungs’ ability to absorb necessary amount of oxygen. The exact etiology of IPF is unknown, but recent evidence suggests that the distal small airways (those having a diameter of less than 2mm) play a role in the early pathogenesis of IPF. more...

(Submitter supplied) We performed a single cell RNA-seq survey of 14,704 invasive fibroblasts and 16,104 non-invasive fibroblasts using an in vitro assay system which had been previously used to evaluate the ability of lung fibroblasts to spontaneously invade Matrigel and commonly used to analyze the metastatic potential of cancer cells. Different subtypes in invasive or non-invasive lung fibroblasts were classified, and their gene signatures, specific cell surface markers, long non-coding RNA (lncRNA), key transcription factors and signaling pathways were further confirmed mechanistically and functionally. more...

(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) Idiopathic pulmonary fibrosis (IPF) is a specific form of chronic progressive fibrosing interstitial pneumonia leading to progressive dyspnea and finally death.The classic diagnosis of IPF is based on the histological pattern of usual interstitial pneumonia (UIP).we have no information about the molecular events that characterize the progression of IPF in the human lung. Understanding the molecular changes that characterize the progression of IPF from early, through progressive changes and into end-stage would allow development of therapeutic strategies that address the disease in all of its stages.In this study we applied a systems biology approach to model dynamic molecular changes during the progression of IPF in the human lung by using a unique resource of carefully characterized, differentially affected regions in human lungs.
