Project description:This study aimed to establish an epithelial-mesenchymal transition (EMT) model with an immortalized human bronchial epithelial cell line, M-BE, and to identify an EMT signature gene set. The TGF-β1-induced M-BE cells got spindle-shaped fibroblast-like morphology and lost the cell-cell contact, with down-regulated expression of epithelial marker E-cadherin and up-regulated expression of mesenchymal markers N-cadherin and Vimentin. Examined by microarray, there were 2628 genes identified as significant EMT-related, including 1490 up-regulated genes (FC > 2, fdr < 0.01) and 1138 down-regulated genes (FC < 0.5, fdr < 0.01) in TGF-β1-induced M-BE cells.

Examined by microarray, there were 2628 genes identified as significant EMT-related, including 1490 up-regulated genes (FC > 2, fdr < 0.01) and 1138 down-regulated genes (FC < 0.5, fdr < 0.01) in TGF-M-NM-21-induced M-BE cells. M-BE cells were treated with human recombinant TGF-M-NM-21 (5ng/ml) for six days. M-BE cells cultured without TGF-M-NM-21 were considered the controls. Three replicates of each were carried out for this investigation. Agilent 4x44K Human Whole Genome expression microarray (G4112F) analysis was applied to the RNA samples of the TGF-M-NM-21-treated M-BE cells and the controls.

Project description:We studied miRNAs and their gene targets affecting SARS-CoV-2 pathogenesis in CF airway epithelial cell models in response to TGF-β1. Small RNAseq in CF human bronchial epithelial cell line treated with TGF-β1 and miRNA profiling characterized TGF-β1 effects on the SARS-CoV-2 pathogenesis pathways. Among the effectors, we identified and validated two miRNAs targeting ACE2 mRNA using different CF and non-CF human bronchial epithelial cell models. We have shown that TGF-β1 inhibits ACE2 expression by miR-136-3p and miR-369-5p. ACE2 levels were higher in cells expressing F508del-CFTR, compared to wild-type(WT)-CFTR and TGF-β1 inhibited ACE2 in both cell types. The ACE2 protein levels were still higher in CF, compared to non-CF cells after TGF-β1 treatment. TGF-β1 prevented the functional rescue of F508del-CFTR by ETI in primary human bronchial epithelial cells while ETI did not prevent the TGF-β1 inhibition of ACE2 protein. Finally, TGF-β1 reduced binding of ACE2 to the recombinant monomeric spike RBD. Our results may help to explain, at least in part, the role of TGF-β1 on the SARS-CoV-2 entry via ACE2 in the CF and non-CF airway.

Project description:Despite being exposed to respiratory syncytial virus (RSV) infection multiple times in our lives, infants, older-adults, and immunocompromised patients are vulnerable to RSV-associated severe diseases, such as bronchiolitis and pneumonia. Respiratory viral infections are known to promote pulmonary fibrosis formation, which are often associated with a cellular remodeling process epithelial-mesenchymal transition (EMT). However, there is no information on whether RSV causes EMT in bronchial epithelial cells. Our results suggest that RSV-infection does not induce EMT in three different in vitro lung models: epithelial A549 cell line, primary normal human bronchial epithelial cells, and pseudostratified airway epithelium. Interestingly, RSV infection increased cell surface area and perimeter in the infected airway epithelium, which is distinct from the TGF-β1 driven cell elongation. Genome-wide transcriptome analysis also revealed that RSV infection is not involved in cell motility and locomotion. Thus, our results suggest that RSV infection does not induce EMT in the airway epithelium

Project description:The purpose of this study was to increase the current knowledge about the LMTK2 network and its intersection with the TGF-β1 signaling pathway. To understand how the LMTK2 and TGF-β1 pathways interconnect, we knocked down LMTK2 using small(si)RNA-mediated silencing in human bronchial epithelial CFBE41o- cells, treated cells with TGF-β1 or vehicle control, and performed differential gene expression analysis by RNA sequencing (RNAseq).

Project description:To identify the dysregulated lncRNA and mRNA expression in ARPE-19 cells underwent EMT, we established a TGF-β1 induced EMT model of ARPE-19 cells. ARPE-19 cells were treated with or without 10 ng/ml TGF-β1 for 48 h. Total RNA are extracted and subjected to microarray assay (Arraystar Human LncRNA Microarray V3.0)

Project description:Vicious circle of some key proteins is critical in the process of tumor development. Nevertheless, the mechanism of how the epigenetic modifiers are involved in was seldom reported and has not been clearly illustrated. We found the expression of lysine specific demethylase 1 (LSD1), the first identified histone lysine demethylase, is positively correlated with transforming growth factor beta 1 (TGF β1) in gastric cancer tissues and can be promoted by TGF β1 activated (p-EKR)-(NF-κB)-p300 signaling pathway, which resulted in the progression of epithelial-mesenchymal transition (EMT) in human gastric cancer cells. On the other hand, abrogation of LSD1 leads to the down regulation of TGF β1 as well as the EMT. But in benign cells, this circle was blocked by TGF β1 induced inactivation of ERK, which suggested the distinct roles of TGF β1 against LSD1 in gastric cancer cells and benign cells. This vicious cycle may illustrate a novel mechanism for EMT in gastric cancer mediate by TGF β1 and LSD1 but not in benign cells and may serve as a new strategy for the prevention of EMT for gastric cancer.

Project description:PHF8 exerts distinct functions in different types of cancer. However, the mechanisms underlying its specific functions in each case remain obscure. To establish whether overexpression of PHF8 regulates the TGF-β induced the epithelial-mesenchymal transition (EMT), we treated MCF10A-Mock (control) and MCF10A-PHF8wt (overexpressing wild-type PHF8) cells with TGF-β1 for 0, 24, 48 and 72 hours and performed RNA-seq in biological duplicates. Our data indicated that EMT gene signatures were significantly enriched in MCF10A-PHF8 cells with TGF-β1 treatment at all time points, strongly indicating that PHF8 overexpression induces a sustained EMT signaling program.
