Brain endothelial cells with inflammatory signature in CCM disease in hypoxia and normoxia conditions (HUVECs)


ABSTRACT: Endothelial cells respond to forces generated by laminar blood flow with changes in vasodilation, anticoagulant, fibrinolytic, or anti-inflammatory functions which preserve vessel patency. These responses to flow are primarily mediated by the elevation of transcription factors Krüppel-like factors 2 and 4 (KLF2 and KLF4). Notably, turbulent flow patterns, which predispose to atherosclerosis, significantly reduce the endothelial expression of KLF2 and KLF4 and reulting changes in the transcriptome that exacerbate inflammation and thrombosis. The CCM complex, comprising KRIT1, CCM2, and CCM3 suppress expression of KLF2 and KLF4. Loss of function of the CCM complex has recently been suggested to protect from coronary atherosclerosis in humans. We thus hypothesized that silencing of KRIT1, the central scaffold of the CCM complex, can normalize the effects of turbulent flow on the human endothelial transcriptome. We conducted bulk RNA sequencing (RNA-seq) on human umbilical vein endothelial cells (HUVECs) after silencing KRIT1 expression using specific siRNAs. The endothelial cells were exposed to pulsatile shear stress (laminar flow), oscillatory shear stress (disturbed flow), or no flow for 24 hours.
