Effect of canonical aryl hydrocarbon receptor pathway inhibitor on human endothelial cells

Project description:To study the effect of blockade of canonical aryl hydrocarbon receptor (AHR) pathway in human endothelial cells, we treated human umbilical vein endothelial cells (HUVECs) and adipose endothelial cells with a canonical AHR inhibitor, Stemreginin 1 (SR1) and performed bulk RNAseq analysis.

Endogenous aryl hydrocarbon receptor ligands-dysregulated phosphoproteomes and proteomes in human fetal endothelial cells

Project description:Preeclampsia (PE) is a leading cause of maternal and fetal morbidity and mortality and is characterized by a wide spectrum of impaired maternal and fetal vascular function. Aryl hydrocarbon receptor (AhR, a ligand-activated transcription factor) plays a critical role in regulating vascular development and function. Endogenous AhR ligands can induce endothelial dysfunction. However, the underlying protein phospho-signaling mechanisms remain unknown. To determine if endogenous AhR ligands dysregulate the phosphoproteomes and proteomes in endothelial cells, primary human umbilical vein endothelial cells (HUVECs) (n = 4; 2 cell preparations/cell sex) were cultured in endothelial cell media (ECM). After 16 hr serum starvation, subconfluent cells were treated with 1 µM 2-(1’H-indole-3’-carbonyl)-thiazole-4-carboxylic acid methyl ester (ITE, an endogenous AhR ligand) or DMSO (vehicle) for 4 and 24 hr. The cell proteins were subjected to a bottom-up phosphoproteomic analysis to determine acute and prolonged effects of ITE on protein phosphorylation.

Endogenous aryl hydrocarbon receptor ligands-dysregulated transcriptomic profiles and endothelial function in human fetal endothelial cells

Project description:Preeclampsia (PE) is a hypertensive disorder and a leading cause of maternal and fetal mortality and morbidity during human pregnancy. Aryl hydrocarbon receptor (AhR), a ligand-activated transcription factor, regulates vascular development and function during pregnancy. Here, we report the important role of endogenous AhR ligands in endothelial growth and function during pregnancy using human umbilical vein endothelial cells (HUVECs) as a model. We found that ITE, ([2-(1’H-indole-3’-carbonyl)-thiazole-4-carboxylic acid methyl ester], an endogenous AhR ligand) decreased cell proliferation and monolayer integrity in HUVECs in vitro. ITE also dysregulated transcriptomic profiles of HUVECs in a fetal sex-specific manner. The ITE-dysregulated genes were enriched in biological function and pathways highly relevant to cardiovascular diseases, vascular function, and inflammation responses. We conclude that dysregulation of endogenous AhR ligands may contribute to the PE-impaired endothelial function through fetal sex-specific regulation of endothelial transcriptomes. These AhR ligand-activated genes and pathways might represent promising therapeutic and sex-specific targets for PE-impaired endothelial function.

Zebrafish larvae aryl hydrocarbon receptor ligands and inhibitor

Project description:Wild type zebrafish (AB strain, https://zfin.org/action/genotype/view/ZDB-GENO-960809-7) were set up for mating overnight, in 3:2 ratios, females and males, respectively. Fertilized embryos from wildtype zebrafish AB strain were used for all experiments and kept in Embryo medium (E3, 5 mM NaCl, 0.17 mM KCl, 0.33 mM CaCl2, 0.33 mM MgSO4) in an incubator at 28ºC. At 1dpf, larvae were manually dechorionated under a stereomicroscope. At 2dpf, zebrafish larvae were divided randomly into the different experimental groups, at a density of 12 larvae per well of a 12 well plate (Corning) in 1.5mL of E3. Three biological replicates of 12 larvae per condition were exposed to different conditions for 4 hours at 28 ºC: DMSO; DMSO + CH223191 (5mM); 3-o-C12-L-HSL (50mM); 3-o-C12-L-HSL (50mM) + CH223191 (5 mM ); 1-hydroxyphenazine (1-HP, 5mM); 1-HP (5mM) + CH223191(5mM) and 1-HP (5mM) + 3-o-C12-L-HSL (50mM).To mention, in experiments using the Aryl hydrocarbon Receptor inhibitor CH223191, larvae were pre-exposed to 5uM of the inhibitor for 2h prior to the start of the experiment and the inhibitor was kept during the experiment. After the desired exposure to diverse ligands, larvae were euthanized with Tricaine (MS-222, 300 µg/mL) and placed in Trizol for RNA isolation. The same experimental layout was performed 5 times, and samples were subjected to microarray hybridization and analysis.

Aryl hydrocarbon receptor (AHR)-dependent protection against lung vascular leakage in viral infection

Project description:Disruption of the lung endothelial-epithelial cell barrier during respiratory virus infection causes cell and fluid accumulation in the air spaces and compromises vital gas exchange function. Endothelial cell dysfunction is known to exacerbate tissue damage; however, it is unclear whether the lung endothelium engages in tissue-protective activity during viral infection. Here we show that the environmental sensor aryl hydrocarbon receptor (AHR) is predominantly active in endothelial cells and protects against influenza-induced lung damage. Endothelial-specific AHR deletion caused increased vascular leakage in air spaces and enhanced influenza-induced lung tissue pathology. Global expression profiling revealed limited AHR-dependent regulation of vessels in the steady-state lung. However, following influenza-induced tissue damage and inflammation, AHR engages tissue-protective programmes in endothelia and prevents a dysplastic keratinised and apoptotic signature in the airways of infected lungs.
