(Submitter supplied) Pulmonary fibrosis is a disease characterized by inflammatory cell infiltration, scar formation, deposition of extracellular matrix, alveolar epithelial cell injury and hyperplasia. To determine if alterations in microRNA expression contribute to these phenotypes, microRNA expression profiling of the lungs from bleomycin treated C57Bl/6J mice, relative to that of untreated controls, was undertaken. Mice were treated at 8 weeks old with 100 Units/kg of bleomycin delivered subcutaneously with osmotic minipumps. At 42 days post treatment mice were euthanized and lung microRNA isolated. We identified 11 microRNA's to be significantly differentially expressed (FDR threshold of 0.01) in the lungs of bleomycin treated mice and confirmed these data with real time PCR measurements. These included bleomycin upregulated miR-34a, 335-5p, 207, 21, 301a, 146b, 199a-5p, and 449a and bleomycin downregulated miR-151-3p, 26a and 676. We have previously shown that 1558 genes are differentially expressed in the lungs of bleomycin treated mice. Of the 1412 targets of upregulated microRNAs, 142 were confirmed to be downregulated in the gene expression profile (GEP). Of the 583 targets of downregulated microRNAs, 53 were confirmed to be upregulated in the gene expression profile. Pathway analysis of the microRNA targets and GEP overlapping genes indicated that altered microRNA expression is associated with cellular development, cellular growth, cellular proliferation and changed tissue/cell morphology. Specific pathways include HGF signaling, Cholecystokinin/Gastrin-mediated signaling, Endothelin-1 signaling, RAR activation, Phospholipase C signaling and IGF1 signaling. We conclude that altered microRNA expression is a feature of pulmonary fibrosis which putatively influences components of the altered airway disease.

(Submitter supplied) The molecular mechanisms of lung injury and fibrosis are incompletely understood. microRNAs (miRNAs) are crucial biological regulators by suppression of their target genes and are involved in a variety of pathophysiologic processes. To gain insight into miRNAs in the regulation of lung fibrosis, total RNA was isolated from lung samples harvested at different days after bleomycin treatment, and miRNA array was performed thereafter. 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...

Herein, we completed microRNA expression profiling of the intestinal tissue from the cystic fibrosis mouse model of cystic fibrosis transmembrane conductance regulator (Cftr) deficient mice (BALBc/J Cftrtm1UNC), relative to that of wildtype littermates, to determine whether changes in microRNA expression level are part of this phenotype. more...

(Submitter supplied) Secretoglobin (SCGB) 3A2 is a cytokine-like secretory protein and is predominantly expressed in airway epithelial cells. While SCGB3A2 is known to have anti-inflammatory, growth factor, and anti-fibrotic activities, its roles in lung homeostasis and diseases are still elusive. In order to obtain an insight into these roles, a transgenic mouse line over-expressing SCGB3A2 in the lung using the human surfactant protein-C promoter was established.

(Submitter supplied) Lymphotoxin β-receptor-signalling orchestrates lymphoid neogenesis and subsequent tertiary lymphoid structures (TLS) associated with severe chronic inflammatory diseases spanning multiple organ systems. How LTβR-signalling drives chronic tissue damage particularly in the lung, which mechanism(s) regulate this process, and whether LTβR-blockade might be of therapeutic value has remained unclear. Here we demonstrate increased lymphotoxin expression of LTbR-ligands on myeloid and adaptive and innate immune-cells, enhanced non-canonical NF-κB signalling and enrichment of LTβR-target gene expression in epithelial cells of lungs from patients and mice with smoking-associated chronic obstructive pulmonary disease (COPD). more...

(Submitter supplied) Idiopathic pulmonary fibrosis (IPF) is a chronic and often fatal pulmonary disorder characterized by fibroblast proliferation and the excess deposit of extracellular matrix proteins. The etiology of IPF is unknown, but a central role for microRNAs (miRNAs), a class of small non-coding regulatory RNAs, has been recently suggested. We report the upregulation of miR-199a-5p in mouse lungs undergoing bleomycin-induced fibrosis and also in human biopsies from IPF patients. more...

(Submitter supplied) To identify putative novel specific targets of mir-199-5p, we overexpressed miR-199a-5p as well as miR-21 and a siRNA targeted against CAV1 in human HFL1 pulmonary fibroblasts (CCL-153) by transfecting them with synthetic pre-miRNAs or a synthetic “negative” pre-miRNA as control (miR-Neg). RNA samples were harvested at 48 hours post-transfection and 2 independent experiments were carried out. Additional samples correspond to HFL1 cells treated or not with 10ng/ml TGFbeta for 48 hours in the absence of serum (2 independent experiments).
