Pneumonia-Induced Endothelial Amyloids Reduce Dendritic Spine Density in Brain Neurons

Researchers used electrophysiological studies in brain slices and structural analysis of post-mortem tissues obtained from animals exposed to endothelium-derived amyloids. The amyloids were administered via three different routes, by intracerebroventricular, intratracheal, and intraperitoneal injections.

miR-503-5p Inhibits Colon Cancer Tumorigenesis, Angiogenesis, and Lymphangiogenesis by Directly Downregulating VEGF-A

Scientists observed considerable downregulation of miR-503-5p expression in colon cancer cells and tissues and significant correlation with the TNM stage, differentiation grade and lymph node metastasis of colon cancer. Overexpression of miR-503-5p promoted the apoptosis and G1 arrest of colon cancer cells, and inhibited migration, proliferation, invasion and colony formation.

Essential Contribution of Macrophage Tie2 Signaling in a Murine Model of Laser-Induced Choroidal Neovascularization

Scientists observed that Tie2-expressing macrophages prevented apoptosis of b.End3 cells, but promoted their migration, proliferation and tube formation via VEGF, extracellular signal-regulated kinase and v-akt murine thymoma viral oncogene-dependent signaling pathways.

Neural Metabolic Imbalance Induced by MOF Dysfunction Triggers Pericyte Activation and Breakdown of Vasculature

The authors showed that neural-specific depletion of three members of the non-specific lethal chromatin complex—Mof, Kansl2 or Kansl3—unexpectedly led to severe vascular defects and brain hemorrhaging.

Human-iPSC-Derived Cardiac Stromal Cells Enhance Maturation in 3D Cardiac Microtissues and Reveal Non-cardiomyocyte Contributions to Heart Disease

Scientists showed that tri-cellular combinations of human induced pluripotent stem cells (iPSC)-derived cardiomyocytes, cardiac fibroblasts, and cardiac endothelial cells enhanced maturation in easily constructed, scaffold-free, three-dimensional microtissues.

Blocking Endothelial Apoptosis Revascularises the Retina in a Model of Ischemic Retinopathy

Researchers investigated the role of endothelial cell (EC) apoptosis in retinal hypoxia using a mouse model of ischemic retinopathy, in which vessel closure and EC apoptosis caused capillary regression and retinal ischemia followed by neovascularisation.

Molecular Mechanisms of Methylglyoxal-Induced Aortic Endothelial Dysfunction in Human Vascular Endothelial Cells

Investigators found that methylglyoxal significantly induced autophagy, declined the pro-angiogenic effect, decreased proliferation, migration, and formation of tube-like structures, and increased autophagic vacuoles, flux and autophagosomes in the HAoEC in a dose-dependent manner.

NRP2 as an Emerging Angiogenic Player; Promoting Endothelial Cell Adhesion and Migration by Regulating Recycling of α5 Integrin

The authors demonstrated that neuropilin (NRP)2 promoted Rac-1 mediated endothelial cell adhesion and migration over fibronectin matrices in a mechanistically distinct fashion to NRP1, showing no dependence on β3 integrin expression, or VEGF stimulation

Angiogenic Cytokines Can Reflect the Synovitis Severity and Treatment Response to Biologics in Rheumatoid Arthritis

To determine the clinical significance of angiogenic cytokines in rheumatoid arthritis (RA), the levels of pro-angiogenic cytokines, including VEGF, placenta growth factor, and IL-6, were measured in the synovial fluid and sera of RA patients using ELISA.

Amplification of Transglutaminase 2 Enhances Tumor-Promoting Inflammation in Gastric Cancers

Scientists investigated a novel role for transglutaminase 2 (TGM2) in the development of tumor-promoting inflammation and recruitment of tumor-associated macrophages to gastric cancer (GC) tissues. When estimated by array comparative genomic hybridization and droplet digital PCR, the copy numbers of the TGM2 gene were amplified in 13.6% of GC patients and positively associated with TGM2 expression.

Glucose-Induced Duration-Dependent Genome-Wide DNA Methylation Changes in Human Endothelial Cells

Researchers investigated the effects of glucose on whole-genome DNA methylation in small and large vessel endothelial cell lines exposed to basal or high glucose-containing media for variable lengths of time. Using the Infinium EPIC array, they obtained 773,133 CpG sites for analysis.
