Stenosis coexists with compromised α1-adrenergic contractions in the ascending aorta of a mouse model of Williams-Beuren syndrome
2020
Williams-Beuren syndrome (WBS) is a rare disorder caused by a heterozygous deletion of 26-28 contiguous genes that affects the brain and cardiovascular system. Here, we investigated whether WBS affects aortic structure and function in the complete deletion (CD) mouse model harbouring the most common deletion found in WBS patients. Thoracic aortas from 3-4 months-old male CD mice and wild-type littermates were mounted in wire myographs or were processed for histomorphometrical analysis. Nitric oxide synthase (NOS) isoforms and oxidative stress levels were assessed. Ascending aortas from young adult CD mice showed moderate (50%) luminal stenosis, whereas endothelial function and oxidative str…
Uric acid treatment after stroke modulates the Krüppel-like factor 2-VEGF-A axis to protect brain endothelial cell functions: Impact of hypertension
2019
Uric acid (UA) is a promising protective treatment in ischaemic stroke, but the precise molecular targets underlying its in vivo beneficial actions remain unclear. High concentrations of UA inhibit angiogenesis of cultured endothelial cells via Krüppel-like factor 2 (KLF)-induced downregulation of vascular endothelial growth factor (VEGF), a pro-angiogenic mediator that is able to increase blood–brain barrier (BBB) permeability in acute stroke. Here, we investigated whether UA treatment after ischaemic stroke protects brain endothelial cell functions and modulates the KLF2-VEGF-A axis. Transient intraluminal middle cerebral artery (MCA) occlusion/reperfusion was induced in adult male sponta…
