(Submitter supplied) Pulmonary fibrosis (PF) is a chronic interstitial lung disease that causes irreversible and progressive lung scarring and respiratory failure. Activation of fibroblasts (FBs) play a central role in progression of PF. Here we report that platelet endothelial aggregation receptor 1 (Pear1) in FBs is a new molecular target for PF therapy. Pear1 deficiency spontaneously caused respiratory function decline and alveolar collagens accumulation in old mice. more...

(Submitter supplied) Intratracheal transfer of isolated lung fibroblasts in bleomycin-induced lung fibrosis recapitulates the activation process of lung fibroblasts after epithelial injury. In order to investigate gene expression signatures of transferred fibroblasts, we purified transferred fibroblasts 2, 4, and 7 days after the transfer and performed transcriptome analysis. We also isolated Acta2 high and low cells by using Acta2-mKO1 reporter mice 4 days after the transfer.

(Submitter supplied) In brief, we have applied a novel and unbiased approach to identify distinct and dynamic cell populations, including an in-depth analysis of the fibroblast population, in lung fibrosis. We found that while fibroblast number did not increase after injury, a population of activated fibroblasts can be identified in the fibrotic mouse lung. Using expression profiles of 1,945 lung fibroblasts we redefine the molecular characteristics of activated fibroblasts, finding that they are not a separate population but rather exhibit a similar, yet amplified, gene expression pattern to non-activated cells.

(Submitter supplied) Lung fibroblasts play a pivotal role in pulmonary fibrosis, a devastating lung diseases, by producing extracellular matrix. MicroRNAs (miRNAs) suppress a lot of genes posttranscriptionally, but the dynamics and the role of miRNAs in activated lung fibroblasts in fibrotic lung has been poorly understood. We found miR-19a, 19b and 20a subcluster expression increased in activated lung fibroblasts as the fibrosis progression. more...

MicroRNAs (miRNAs) suppress a lot of genes posttranscriptionally, but the dynamics and the role of miRNAs in activated lung fibroblasts in fibrotic lung has been poorly understood.

(Submitter supplied) 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.

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) is a progressive, irreversible fibrotic disease of the distal lung alveoli that culminates in respiratory failure and reduced lifespan. Unlike normal lung repair in response to injury, IPF is associated with the accumulation and persistence of fibroblasts and myofibroblasts and continued production of collagen and other extracellular matrix (ECM) components. Prior in vitro studies have led to the hypothesis that the development of resistance to Fas-induced apoptosis by lung fibroblasts and myofibroblasts contibributes to their accumulation in the distal lung tissues of IPF patients. more...

(Submitter supplied) TGFβ is one of most intensively studied regulators of extracellular matrix formation, and has been implicated in the development of pulmonary fibrosis in different models. However, little is know about the role of miRNAs in TGFβ mediated fibrogenic gene regulation. By using miRNA qRT-PCR array, we have identified miRNAs whose expression are regulated by TGFβ in IMR-90 cells. Among those down-regulated miRNAs are miR-29 family members. more...

(Submitter supplied) We conducted fibroblast-specific transcriptome analysis by next generation sequencing in order to investigate qualitative change and activation signatures of lung fibroblasts in bleomycin-induced pulmonary fibrosis. Lung fibroblasts were identified by using reporter mice of collagen-α2(I), in which collagen I-producing fibroblasts were labeled with EGFP. Lungs were dissociated with protease sollution, and single cell suspension were stained with lineage markers (Ter119, CD45, CD31, EpCAM). more...

(Submitter supplied) Archived lung tissues of patients with IPF were obtained from the tissue bank of the Department of Pathology at the University of Pittsburgh. The diagnosis of IPF was confirmed by open lung biopsy. All patients fulfilled the criteria of the American Thoracic Society and European Respiratory Society for the diagnosis of IPF. Normal histology lung tissues resected from patients with lung cancer were used as controls. more...

(Submitter supplied) Lung fibrosis represents the final common pathway of a variety of lung injuries, and it is characterized, independently of etiology, by the expansion of the fibroblast/myofibroblast population and by the abnormal accumulation of extracellular matrix (ECM) replacing normal functional parenchyma. In general, there is no effective therapy, and currently the only helpful available treatment for advanced lung fibrosis is transplantation. more...

(Submitter supplied) The capacity of lung tissue to heal without scarring deteriorates with aging. The pulmonary vasculature has emerged as a central regulator of lung repair, and aging-associated endothelial cell dysfunction has been associated with defective lung response to injury and sustained fibrosis. To shed light into aging-associated cellular and transcriptional responses of lung endothelial cells during lung fibrogenesis, we carried out a single cell RNA-seq analysis of bleomycin-treated young (2 months) and aged (72 months) lungs during the early phase of fibrosis resolution (30 days post bleomycin). more...

(Submitter supplied) Hyperbaric oxygen (HBO) is widely applied to treat a number of hypoxia-related diseases. Previous studies focused on the immediate effect of HBO-exposure induced oxidative stress on lungs, but knowledge regarding the chronic effects from repetitive HBO exposure is limited, especially at the gene expression level. We found that repetitive HBO exposure did not alter the morphology of murine lungs. However, by deconvolution of RNA-seq from those mice lungs using CIBERSORTx and the expression profile matrices of 8 mesenchymal cell subtypes obtained from bleomycin-treated mouse lungs, we identify several mesenchymal cell subtype changes. more...
