Project description:Idiopathic pulmonary fibrosis (IPF) is a lethal fibrotic lung disease characterized by enhanced fibroblast proliferation, collagen synthesis, extracellular matrix deposition. We obtained 28 IPF patient lung tissue samples from the Lung Tissue Research Consortium (LTRC). Here we determined the miRNA expression profiles in these IPF lung samples.

Project description:Idiopathic pulmonary fibrosis (IPF) is a disease related to AT2 cell. We used flow cytometry to analyze the epithelial component of donor and IPF lungs. From the live cells, we first excluded the CD31PosCD45Pos and then selected the EPCAMPos cells for further analysis using the human AT2 cell marker HTll-280 and the surface marker PD-L1. Our data indicate that, the bona fide differentiated AT2 cells (HTll-280High PD-L1Neg), were drastically reduced in the context of IPF. More interestingly, the number of HTll-280Low/Neg PD-L1High was drastically increased, suggesting that HTll-280Low PD-L1High epithelial cells could represent a pool of progenitors linked to the deficient AT2 lineage. The aim of this experiment is further characterization of AT2 and PDL1+ cells in donor and IPF.

Project description:Idiopathic pulmonary fibrosis (IPF) is an untreatable fibrotic lung disease characterized by fibroblast proliferation and epithelial mesenchymal transition. Using miRNA expression microarrays we identified 96 differentially expressed miRNA in IPF lungs which included let-7d, miR-30 family, miR-29 family and miR-154 family.

Project description:Idiopathic pulmonary fibrosis (IPF) is an untreatable fibrotic lung disease characterized by fibroblast proliferation and epithelial mesenchymal transition. Using miRNA expression microarrays we identified 96 differentially expressed miRNA in IPF lungs which included let-7d, miR-30 family, miR-29 family and miR-154 family. Lung tissue samples for microarray analysis were obtained through the University of Pittsburgh Health Sciences Tissue Bank. 13 samples were obtained from surgical remnants of biopsies or lungs explanted from patients with IPF who underwent pulmonary transplant, and 12 control normal lung tissues obtained from the disease free margins with normal histology of lung cancer resection specimens. The morphologic diagnosis of IPF was based on typical microscopic findings consistent with usual interstitial pneumonia. Total RNA was labeled with Cy3 and hybridized on Agilent 8X15K microRNA array (Agilent Technologies, Santa Clara, CA). After 20 hours hybridization, arrays were washed and scanned according to the manufacturer’s protocol.

Project description:Idiopathic pulmonary fibrosis (IPF), a chronic progressive lung disease of unknown etiology, is characterized by the expansion of myofibroblasts and abnormal deposition of extracellular matrix in the lung parenchyma. To elucidate the molecular mechanisms that lead to IPF, we analyzed myofibroblasts established from patients with IPF by oligonucleotide microarrays. Gene expression profiles revealed a novel pathophysiologic function of myofibroblasts as a generator of reactive oxygen species, and a self-defense mechanism against oxidative stress of their own generating. Experiment Overall Design: We isolated two myofibroblast cell culture from patients with idiopathic pulmonary fibrosis. Embryonic pulmonary fibroblast was used for the reference.

Project description: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. Total RNA obtained from Idiopathic pulmonary fibrosis samples.

Project description:The aim of the current study is to find plasma-based biomarker candidates for Idiopathic Pulmonary Fibrosis (IPF). Incidence of IPF seems to be increasing in Europe and there is significant mortality associated with IPF. There are no sensistive biomarkers for IPF and diagnosis is entirely clinical and/or histopathological which is often delayed. Minimally invasive biomarkers of IPF would be expected to aid clinicians perfrom early diagnosis of IPF enabling better management of the disease.

Project description:Visium (10x Genomics) spatially resolved transcriptomics data generated from normal and Idiopathic Pulmonary Fibrosis (IPF) lung parenchyma tissues collected from human donors. The fresh-frozen tissues that were analyzed were from four healthy control (HC) subjects and from four IPF patients. For each IPF patient, three different tissues were selected representing areas of mild (“B1”), moderate (“B2\") or severe (“B3”) fibrosis within the same donor, as determined by histological inspection of Hematoxylin and Eosin (H&E)-stained samples. Data from a total of 25 tissue sections, from 16 unique lung tissue blocks. The lung tissues were collected post-mortem (HC donors) or during lung transplant/resection (IPF patients) after obtaining informed consent. The study protocols were approved by the local human research ethics committee (HC: Lund, permit number Dnr 2016/317; IPF: Gothenburg, permit number 1026-15) and the samples are anonymized and cannot/should not be traced back to individual donors.
