DDX24 Spatiotemporally Orchestrates VEGF and Wnt Signaling During Developmental Angiogenesis

Research Background Vascular system development is a highly precise regulatory process involving two key stages: vasculogenesis and angiogenesis. Although the VEGF (vascular endothelial growth factor) and Wnt signaling pathways have been confirmed to regulate vascular development in the peripheral and central nervous systems (CNS), respectively, th...

METTL3 Mediates Atheroprone Flow–Induced Glycolysis in Endothelial Cells

1. Research Background Atherosclerosis is the primary pathological basis of cardiovascular diseases, closely associated with endothelial cell (EC) dysfunction. Hemodynamic factors play a critical role in the regional selectivity of atherosclerosis: oscillatory shear stress (OS) (e.g., at vascular bifurcations) promotes plaque formation, while pulsa...

Theoretical and Experimental Studies of the Dynamic Damage of Endothelial Cellular Networks under Ultrasound Cavitation

Endothelial cells play a crucial role in the vascular system, regulating hemostasis, vasodilation, immune responses, and inflammation through intercellular junctions (IJs). However, excessive mechanical loading can lead to endothelial cell damage and endothelial barrier dysfunction. Understanding the dynamic rupture mechanisms of intercellular junc...

Matrix Stiffness-Mediated DNA Methylation in Endothelial Cells

In pathological conditions, alterations in tissue mechanical properties are one of the prominent features of many diseases, such as cancer. The tumor vascular system plays a critical role in tumor growth, but its structure and function often become abnormal, manifesting as disorganized, tortuous, and leaky blood vessels. Research has shown that the...

Bioprinted Micro-Clots for Kinetic Analysis of Endothelial Cell-Mediated Fibrinolysis

Breakthrough Research on Micro-Scale Exploration of Thrombolysis Kinetics Research Background and Problem Venous thromboembolism (VTE), a severe health condition, causes approximately 500,000 deaths annually in the United States alone. The occurrence of VTE is closely related to the formation and resistance to dissolution of thrombi in veins, commo...

An Organotypic Atlas of Human Vascular Cells

Decoding the Human Vascular System: A Comprehensive Multi-organ Single-cell Transcriptomic Study Reveals Vascular Cell Diversity Background Overview The human vascular system is a core component for sustaining life, comprising endothelial cells (ECs) and mural cells that span across all organ systems. Its functions extend beyond merely delivering b...

Site-Specific Genetic and Functional Signatures of Aortic Endothelial Cells at Aneurysm Predilection Sites in Healthy and AngII ApoE−/− Mice

Site-Specific Genetic and Functional Signatures of Aortic Endothelial Cells at Aneurysm Predilection Sites in Healthy and AngII ApoE−/− Mice Academic Background Aortic aneurysm (AA) is characterized by pathological dilation at specific predilection sites of the vessel, potentially leading to life-threatening vascular rupture. Aortic aneurysms typic...

Oscillatory Contractile Forces Refine Endothelial Cell-Cell Interactions for Continuous Lumen Formation Governed by Heg1/CCM1

Academic Background The formation and maintenance of vascular networks are critical processes in embryonic development and tissue regeneration, involving the regulation of various biophysical forces. Endothelial cells (ECs) play a central role in angiogenesis and vasculogenesis, with the contractile forces of the cytoskeleton (actomyosin contractil...

Endothelial Metabolic Control of Insulin Sensitivity Through Resident Macrophages

Endothelial Cells Influence Insulin Sensitivity Through Metabolic Regulation of Resident Macrophages In recent years, metabolic diseases, especially insulin resistance and diabetes, have become significant global health issues. Muscle tissue, being one of the main organs for glucose metabolism in the human body, has its insulin sensitivity closely ...

Dopaminylation of endothelial TPI1 suppresses ferroptotic angiocrine signals to promote lung regeneration over fibrosis

Dopamine Modification of TPI1 Inhibits Ferroptosis Signaling in Vascular Endothelial Cells, Promoting Lung Regeneration and Inhibiting Fibrosis Background The regenerative capability of the lung enables it to restore its original functional tissue after injury. However, if this regenerative process is disrupted, it often leads to maladaptive repair...
