Hypoxia-Mediated Regulation of Histone Demethylases Affects Angiogenesis-Associated Functions in Endothelial Cells

Previous studies have demonstrated that the expression of several lysine-specific demethylases is induced by hypoxia. The authors investigated the exact mechanisms underlying this regulation and its functional implications for endothelial cell function, such as angiogenesis.

Synthetic Fluorinated L-Fucose Analogs Inhibit Proliferation of Cancer Cells and Primary Endothelial Cells

Researchers describe the design and synthesis of a panel of fluorinated L-fucose analogs bearing fluorine atoms at the C2 and/or C6 positions of L-fucose as metabolic fucosylation inhibitors. Preliminary study of their effects on cell proliferation revealed that the 6,6-difluoro-L-fucose and 6,6,6-trifluoro-L-fucose showed significant inhibitory activity against proliferation of human colon cancer cells and human umbilical vein endothelial cells.

3D Curvature-Instructed Endothelial Flow Response and Tissue Vascularization

Researchers showed proof-of-principle modeling of tumor progression and engineered cardiac tissue vascularization. They demonstrated that 3D curvature induced rotation and mixing under laminar flow, leading to unique phenotypic and transcriptional changes in endothelial cells.

NF-κB Inhibition Prevents Acute Shear Stress-Induced Inflammation in the Saphenous Vein Graft Endothelium

Investigators tested the hypothesis that acute exposure of venous endothelial cells to high shear stress is associated with inflammatory responses that are regulated by NF-κB both in vitro and ex vivo.

THRIL Mediates Endothelial Progenitor Cells Autophagy via AKT Pathway and FUS

THRIL was upregulated in coronary atherosclerotic heart disease (CAD) blood samples and endothelial progenitor cells (EPCs). Knockdown of THRIL in EPCs promoted cell viability, inhibited cell autophagy and further suppressed the development of CAD.
