Summary: Pin1 functions as a key regulator of vascular homeostasis by modulating nitric oxide bioavailability and influencing various pathways involved in vascular diseases. Understanding the role of Pin1 in vascular endothelium could provide new insights for potential therapeutic strategies in vascular pathologies and neurodegenerative diseases.

Summary: The study revealed that BMP9 and BMP10 act directly on VSMCs for induction and maintenance of their contractile state. The effects of BMP9/10 in VSMCs are mediated by different combinations of BMP type 1 receptors in a vessel bed-specific manner, offering new opportunities to manipulate blood pressure in the pulmonary circulation.

Summary: Marfan syndrome is a connective tissue disorder caused by mutations in the FBN1 gene, with progressive aortic root widening being a serious manifestation. Our understanding of MFS-associated aortic remodeling remains fragmented, with nitric oxide synthase-related changes potentially playing a significant role in the pathogenesis.

Summary: Vascular tone regulation by nitric oxide is a crucial physiological function, with endothelial dysfunction potentially being an underlying cause of hypertension. Increasing eNOS activity reduces blood pressure, while decreasing activity has the opposite effect. These findings have important implications for pre-hypertensive treatment.

Summary: The release of dopamine, noradrenaline, adrenaline, and 6-nitrodopamine (6-ND) from Chelonoidis carbonaria aortic rings is coupled to nitric oxide (NO) synthesis. 6-ND acts as a selective dopamine D-2-like receptor antagonist and affects the vascular smooth muscle reactivity.

Summary: This study examines the expression and cellular localization of eNOS, CyB5a, and CyB5R3 in mouse arterial endothelial cells, showing that alpha-globin can be reduced by two independent redox systems, CyB5R3/CyB5a and eNOS. These findings provide new insights into the regulation of blood vessel contractility.

Summary: FXYD1 plays a crucial role in protecting eNOS from oxidative stress and contributes to cardiovascular health; FXYD1 regulates oxidative dysregulation within caveolae where it is colocalized; In addition to impacting eNOS function, FXYD1 is closely associated with hypertension and diabetic vascular oxidative stress.

Summary: eNOS knockout mice exhibit a slower progression of arterial disease compared to C57Bl/6 control mice, with significant regulation of aortic biomechanical parameters by cyclic stretch amplitudes.

Summary: The development of high blood pressure is influenced by genetic and environmental factors, with high salt intake being a known environmental contributor. There is a spectrum of sodium-sensitivity among individuals, partly due to genetic variation in pathways involved in sodium handling and excretion. ENaC plays a crucial role in regulating extracellular fluid volume and blood pressure by facilitating sodium reabsorption in the distal nephron.

Summary: This study demonstrates that eNOS in ECs and RBCs independently contribute to blood pressure homeostasis. EC eNOS KO mice exhibited significantly impaired aortic dilatory responses to acetylcholine, loss of flow-mediated dilation, and increased blood pressure. On the other hand, RBC eNOS KO mice showed no alterations in acetylcholine-mediated dilation or flow-mediated dilation but were hypertensive.

Summary: Calmodulin (CaM) is a crucial protein for multiple functions of vascular smooth muscle cells (VSMCs) and its expression and interactions with target proteins in VSMCs can be regulated by endothelial cells (ECs). In this study, it was discovered that proliferating ECs can upregulate total CaM expression and enhance Ca2+-bound CaM levels in VSMCs co-cultured with ECs. This endothelium-dependent upregulation of CaM in VSMCs is mediated by vascular endothelial growth factor receptors. These findings reveal a new role of ECs in regulating vascular functions through upregulating CaM and its interactions in VSMCs.

Summary: Dkk3 plays a crucial role in cardiovascular homeostasis, and its deficiency leads to hypertension and impaired vascular function, which can be rescued by restoring Dkk3 expression. This effect is achieved through promoting VEGF expression and activating the VEGF/Akt/eNOS hypotensive pathway.
