Small RNA-Seq analysis of human lung fibroblasts exposed to TGF-β

Project description:To assess the transcriptomic response of human lung fibroblast to TGF-β, human MRC5 pulmonary fibroblasts (CCL-171) were exposed to TGF-β at 10 ng/mL. RNA samples were harvested 24 hours after TGF-β exposition. Three independent experiments were carried out.

RNA-Seq analysis of human lung fibroblasts exposed to TGF-β

Project description:To assess the transcriptomic response of human lung fibroblast to TGF-β, human MRC5 pulmonary fibroblasts (CCL-171) were exposed or not to TGF-β at 10 ng/mL. RNA samples were harvested 24 hours after TGF-β exposition. Three independent experiments were carried out.

Bi-directional epithelial-mesenchymal crosstalk provides self-sustaining pro-fibrotic signals in pulmonary fibrosis

Project description:Idiopathic pulmonary fibrosis (IPF) is the prototypic progressive fibrotic lung disease with a median survival of 2-4 years. Injury to and/or dysfunction of alveolar epithelium are strongly implicated in IPF disease initiation, but what factors determine why fibrosis progresses rather than normal tissue repair occurs remain poorly understood. We previously demonstrated that ZEB1-mediated epithelial-mesenchymal transition (EMT) in human alveolar epithelial type II (ATII) cells augments TGF-β-induced profibrogenic responses in underlying lung fibroblasts by paracrine signalling. Here we investigated bi-directional epithelial-mesenchymal crosstalk and its potential to drive fibrosis progression. RNA sequencing (RNA-seq) of lung fibroblasts exposed to conditioned media from ATII cells undergoing RAS-induced EMT identified many differentially expressed genes including those involved in cell migration and extracellular matrix (ECM) regulation. We confirmed that paracrine signalling between AS-activated ATII cells and fibroblasts augmented fibroblast recruitment and demonstrated that this involved a ZEB1-tissue plasminogen activator (tPA) axis. In a reciprocal fashion, paracrine signalling from TGF-β-activated lung fibroblasts or IPF fibroblasts induced RAS activation in ATII cells, at least partially via the secreted protein, SPARC. Together these data identify that aberrant bi-directional epithelial-mesenchymal crosstalk in IPF drives a chronic feedback loop that maintains a wound-healing phenotype and provides self-sustaining pro-fibrotic signals.

Impact of DNM3OS silencing on human lung fibroblast response to TGF-β

Project description:To assess the role of the lncRNA DNM3OS in TGF-β-induced lung fibroblast activation, we transfected in human MRC5 pulmonary fibroblasts (CCL-171) a gapmer designed against DNM3OS for 48h and then exposed these cells to TGF- β (10 ng/mL). RNA samples were harvested 24 hours after TGF-β exposition. Two independent experiments were carried out.

Impact of PRRX1 knockdown on the transcriptome of normal human lung fibroblasts (NHLF) in the presence or the absence of TGF-β

Project description:To assess the role of PRRX1 in TGF-β-induced lung fibroblast activation, we transfected in human NHLF with PRRX1 or control siRNAs and then exposed these cells to TGF- β (1 ng/mL). RNA samples were harvested 48 hours after TGF-β exposition. Two independent experiments were carried out.

To examine the expression of Sulf1 and Sulf2, as well as other glycan-related genes, in human Idiopathic pulmonary fibrosis (IPF) lungs compared to normal lung samples

Project description:Microarray analysis to examine glycan-related gene expression in idiopathic pulmonary fibrosis Heparan sulfate 6-O-endosulfatases (Sulf1 and Sulf2) remove 6-O sulfate groups from heparan sulfate intra-chain sites on the cell surface and in the extracellular matrix, and modulate the functions of many growth factors and morphogens including FGF, Wnt and TGF-beta. Works from our laboratory have shown that TGF-beta 1 induces Sulf1 and Sulf2 expression in a cell-type specific manner in the lung, specifically Sulf1 in lung fibroblasts and Sulf2 in type II alveolar epithelial cells. Interestingly TGF-beta 1-induced Sulf1 and Sulf2 in turn modulate TGF-beta 1 function in culture. The aim of this study is to examine the expression of Sulf1 and Sulf2 as well as other glycan-related genes (heparan biosynthetic enzymes, TGF-beta, FGF and Wnt signaling pathway components) in human idiopathic pulmonary fibrosis (IPF) lungs compared to normal lung samples. We will examine gene expression in triplicate samples from RNA of total lung homogenates from IPF and control (normal) lungs

Whole-genome microarray analysis of human skin fibroblasts

Project description:Connective tissue growthfactor (CTGF/CCN2) is a matricellular protein induced by transforming growth factor-beta (TGF-beta) and intimately involved with tissue repair and overexpressed in various fibrotic conditions. We have previously shown that keratinocytes in vitro downregulate TGF-beta induced expression of CTGF in fibroblasts by an interleukin-1 alfa (IL-1alfa) dependent mechanism. With this study we want to get a better overall perspective who fibroblasts respond on TGF-beta and in a TGF-Beta stinulated system, what effect addition of IL-1 alfa have. This to understand the expression of CTGF in human fibroblasts which in turn have implications for the pathogenesis of fibrotic conditions involving the skin. Microarray was performed on human skin fibroblast RNA from one patient, Fibroblasts were seeded in vitro as a control (Control, C), TGF-beta were added to fibroblasts and incubated for 16 h (addition of TGF-beta, T) and both IL-1alfa and TGF-beta were added to fibroblasts for 16 h (addition of IL-1alfa and TGF-beta, IT). Each condition (C,T and IT) were done in three replicates.

miRNA expression data in unstimulated and TGF-β1-stimulated lung fibroblasts

Project description: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.
