    High-Sucrose Diets Contribute to Brain Angiopathy with Impaired Glucose Uptake and Psychosis-Related Higher Brain Dysfunctions in Mice

    The authors demonstrated that a high-sucrose diet during adolescence induced psychosis-related behavioral endophenotypes, including hyperactivity, poor working memory, impaired sensory gating, and disrupted interneuron function in mice deficient for glyoxalase-1.

    USP12 Promotes Breast Cancer Angiogenesis by Maintaining Midkine Stability

    Investigators showed that the supernatant from ubiquitin-specific protease 12 (USP12)-overexpressing breast cancer cells could promote angiogenesis according to HUVEC migration and tube formation assays.

    Extracellular Vesicles from Hypoxia-Preconditioned Microglia Promote Angiogenesis and Repress Apoptosis in Stroke Mice via the TGF-β/Smad2/3 Pathway

    By exposing bEnd.3 endothelial cells and primary cortical neurons to oxygen−glucose deprivation (OGD), the impact of extracellular vesicles from OGD-preconditioned microglia on angiogenesis and neuronal apoptosis by the tube formation assay and TUNEL staining was assessed.

    Insulin-Stimulated Adipocytes Secrete Lactate to Promote Endothelial Fatty Acid Uptake and Transport

    Treatment of endothelial cells with insulin did not affect endothelial fatty acid uptake, but endothelial cells took up more fatty acids when exposed to media conditioned by adipocytes treated with insulin.

    Abstract

    A Method for Rapid Flow-Cytometric Isolation of Endothelial Nuclei and RNA from Archived Frozen Brain Tissue

    Scientists developed an approach to examine endothelial RNA expression by using an endothelial-specific marker to isolate nuclei from abundant archived frozen brain tissues.

    Role of Angiogenesis in Beta-Cell Epithelial–Mesenchymal Transition in Chronic Pancreatitis-Induced Diabetes

    Researchers suggested that angiogenesis promoted beta-cell survival in the inflamed pancreas, while suppression of angiogenesis turned beta-cell epithelial–mesenchymal transition into apoptotic beta-cell death.

    Endothelial CCR6 Expression Due to FLI1 Deficiency Contributes to Vasculopathy Associated with Systemic Sclerosis

    In human dermal microvascular endothelial cells, FLI1 siRNA induced the expression of CCR6, but not CCL20, and FLI1 bound to the CCR6 promoter.

    The Effects of Exosomes Derived from Trabecular Meshwork Cells on Schlemm’s Canal Endothelial Cells

    To examine the interaction between trabecular meshwork cells on Schlemm’s canal endothelial cells, the authors investigated whether exosomes contributed to intercellular communication.

    CD146 Mediates the Anti-apoptotic Role of Netrin-1 in Endothelial Progenitor Cells under Hypoxic Conditions

    Researchers explored the role and molecular mechanisms underlying Netrin‑1 in the viability and angiogenic function of endothelial progenitor cells (EPCs). The apoptosis and various functions of EPCs were analyzed in vitro by manipulating the expression of Netrin‑1.

    Crosstalk between the Renin–Angiotensin, Complement and Kallikrein–Kinin Systems in Inflammation

    The authors describe the interactive roles of the renin–angiotensin system, the complement system, and the closely linked kallikrein–kinin and contact systems in cell biological functions such as vascular tone and leakage, inflammation, chemotaxis, thrombosis and cell proliferation.
