(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) 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. To elucidate these problems, we performed global miRNA expression profiling of lung fibroblasts of bleomycin- and silica-induced fibrotic lungs

(Submitter supplied) Lung fibroblasts play an important role in extracellular matrix homeostasis and this process is mainly regulated by transforming growth factor-beta (TGF-β). Hence, lung fibroblasts are postulated to play a crucial role in aberrant lung tissue repair and remodeling, which is a main factor in lung diseases like COPD. In this study, the effect of TGF-β1 on the miRNA expression in parenchymal lung fibroblasts is investigated.

(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 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.

(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).
