Ets homologous factor has critical roles in epithelial dysfunction in airway disease [ChIP-seq]

Project description:Ets homologous factor (EHF) is an Ets family transcription factor expressed in many epithelial cell types including those lining the respiratory system. Disruption of the airway epithelium is central to many lung diseases, and a network of transcription factors coordinates its normal function. EHF can act as a transcriptional activator or a repressor. Chromatin immunoprecipitation followed by deep sequencing (ChIP-seq), showed that EHF binding sites in lung epithelial cells are enriched at promoters and coincide with putative enhancers, marked by specific histone modifications. Using EHF ChIP-seq and RNA-seq after EHF depletion, we show its targets in HBE cells are enriched for genes involved in degradation of misfolded proteins, inflammation, and wound repair.

Ets homologous factor (EHF) has critical roles in epithelial dysfunction in airway disease.

Project description:The airway epithelium forms a barrier between the internal and external environments. Epithelial dysfunction is critical in the pathology of many respiratory diseases, including cystic fibrosis. Ets homologous factor (EHF) is a key member of the transcription factor network that regulates gene expression in the airway epithelium in response to endogenous and exogenous stimuli. EHF, which has altered expression in inflammatory states, maps to the 5' end of an intergenic region on Chr11p13 that is implicated as a modifier of cystic fibrosis airway disease. Here we determine the functions of EHF in primary human bronchial epithelial (HBE) cells and relevant airway cell lines. Using EHF ChIP followed by deep sequencing (ChIP-seq) and RNA sequencing after EHF depletion, we show that EHF targets in HBE cells are enriched for genes involved in inflammation and wound repair. Furthermore, changes in gene expression impact cell phenotype because EHF depletion alters epithelial secretion of a neutrophil chemokine and slows wound closure in HBE cells. EHF activates expression of the SAM pointed domain-containing ETS transcription factor, which contributes to goblet cell hyperplasia. Our data reveal a critical role for EHF in regulating epithelial function in lung disease.

Ets homologous factor regulates pathways controlling response to injury in Calu-3 airway epithelial cells [DNAse-seq]

Project description:Ets homologous factor (EHF) is an Ets family transcription factor expressed in many epithelial cell types including those lining the respiratory system. Disruption of the airway epithelium is central to many lung diseases, and a network of transcription factors coordinates its normal function. EHF can act as a transcriptional activator or a repressor, though its targets in lung epithelial cells are largely uncharacterized. Chromatin immunoprecipitation followed by deep sequencing (ChIP-seq), showed that the majority of EHF binding sites in lung epithelial cells are intergenic or intronic and coincide with putative enhancers, marked by specific histone modifications and increased DNase hypersensitivity.

Disruption of the airway epithelium is central to many lung diseases, and a network of transcription factors coordinates its normal function. EHF can act as a transcriptional activator or a repressor, though its targets in lung epithelial cells are largely uncharacterized. RNA-seq after EHF depletion or overexpression showed significant alterations in the expression of genes involved in response to wounding. EHF knockdown also targeted genes in pathways of epithelial development and differentiation and locomotory behavior. mRNA profiles from Calu-3 cells treated with negative control (NC) or EHF siRNA, in quintuplicate. mRNA profiles from 3 pcDNA (empty vector control) clones and 3 pcDNA-EHF overexpression A549 clones, 3-4 replicates each.
