HUVECs cultured under normal or high laminar shear stress

ABSTRACT: Many studies have characterised the effect of normal laminar shear stress (LSS) on endothelial responses, however elevated shear stress, as would be experienced overlying a stenotic plaque, has not been studied in depth. Therefore we used transcriptomics and related functional analyses to compare cells exposed to laminar shear stress at 15 or 75 dynes/cm2 for 24 hours (LSS15-normal or LSS75-high shear stress).

HUVECs cultured under normal or high laminar shear stress

Project description:Many studies have characterised the effect of normal laminar shear stress (LSS) on endothelial responses, however elevated shear stress, as would be experienced overlying a stenotic plaque, has not been studied in depth. Therefore we used transcriptomics and related functional analyses to compare cells exposed to laminar shear stress at 15 or 75 dynes/cm2 for 24 hours (LSS15-normal or LSS75-high shear stress). Human umbilical vein endothelial cells (HUVEC n=4 per flow condition from different batches of pooled donor HUVEC p2) were cultured for 24 hours on gelatin coated slides under laminar shear stress of either 15 dynes/cm2 or 75 dynes/cm2 (LSS15 or LSS75) to assess the effect of high shear stress on endothelial cells. Total RNA was obtained using Qiagen kit and array analysis performed by Service XS (Leiden, Netherlands).

CircRNA profiling in laminar shear stress-treated human umbilical vein endothelial cells.

Project description:Laminar shear stress (LSS) suppresses endothelial inflammation and protects the arteries from atherosclerosis. Circular RNAs (circRNAs) are powerful regulators of vascular homeostasis and atherosclerosis; however, their roles in mediating the effects of LSS remain unexplored. To identify the changes in circRNA expression patterns after shear stress stimulation, we conducted circRNA microarray analysis using RNA extracted from HUVECs cultured for 24 h under static or LSS conditions.

Comparison of aortic and aortic valve endothelial cells in static and shear environments

Project description:Porcine aortic and aortic valve endothelial cells were exposed to 20 dynes/cm2 steady laminar shear stress with static cultures serving as controls. Total RNA was hybridized to Agilent Human 1 cDNA arrays and processed using the Agilent Feature Extraction Software Keywords = aortic valve Keywords = endothelial Keywords = shear stress Keywords: other

The Adaptive Response of Endothelial Cells to Increased Shear Stress

Project description:In this study, we characterized the adaptive response of arterial endothelial cells to acute increases in shear stress magnitude in well-defined in vitro settings. Porcine endothelial cells were preconditioned by a basal level shear stress of 15 ± 15 dynes/cm2 at 1 Hz for 24 hours, and an acute increase in shear stress magnitude (30 ± 15 dynes/cm2) was then applied. The transcriptomics studies using microarray identified genes that were sensitive to the elevated shear magnitude. A significant number of the identified genes in our study are previously unknown as sensitive to shear stress. Porcine endothelial cells were preconditioned by a basal level shear stress of 15 ± 15 dynes/cm2 at 1 Hz for 24 hours, and an acute increase in shear stress magnitude (30 ± 15 dynes/cm2) was then applied. Gene expression at multiple time points was measured using microarray.

Endothelial Response to Increased Shear Stress Frequency

Project description:Porcine endothelial cells were preconditioned by a basal level shear stress of 15 ± 15 dynes/cm2 at 1 Hz for 24 hours, and an acute increase in shear stress frequency (2 Hz) was then applied. The transcriptomics studies using microarray identified genes that were sensitive to the elevated shear frequency. keywords: adaptation, shear stress, frequency, microarray, gene expression Porcine endothelial cells were preconditioned by a basal level shear stress of 15 ± 15 dynes/cm2 at 1 Hz for 24 hours, and an acute increase in shear stress magnitude (2 Hz) was then applied.

Shear Stress and NOTCH1 Regulate Calcification Related Genes in Human Aortic Valve Endothelium (RNA-Seq)

Project description:We are interested in the role of NOTCH1 and Shear Stress in Aortic Valve Endothelium. Primary human aortic valve endothelium was subjected to 4 conditions in vitro. 1) Control siRNA, No shear stress. 2) NOTCH1 siRNA, No shear stress. 3) Control siRNA, 15 dynes/cm2 shear stress. 4) NOTCH1 siRNA, 15 dynes/cm2 shear stress. Triplicates of each condition were pooled for library perp and sequencing

Transcriptional adaptations of HUVECs exposed to high and low fluid shear stress

Project description:The goal of this study was to identify gene signatures in HUVECs exposed to atheroprone low laminar shear stress (LSS) or atheroprotective high laminar shear stress (HSS). The obtained data was used to verify that HSS and LSS application induces gene expression patterns similar to more complex pulsatile and oscillatory flow, respectively.

Effects of aneurysmal low and supra-high wall shear stress on endothelial gene expression

Project description:Wall shear stress (WSS) is proposed to influence intracranial aneurysm growth and rupture. Physiological WSS in cerebral arteries is estimated around 20-30 dynes/cm2. The WSS typically observed in human IAs is close to 2 dynes/cm2 for wide-neck aneurysms with a slow recirculating flow and >70 dynes/cm2 in aneurysms with impinging “jet flow”. In this study, we investigated the effects of aneurysmal low and supra-high WSS on endothelial cells.
