    Single Cell Transcriptional Analysis of Human Endothelial Colony Forming Cells from Patients with Low VWF Levels

    Scientists observed that endothelial colony forming cells derived from patients with low Von Willebrand Factor (VWF) demonstrated alterations in baseline Weibel Palade body metrics and exhibited impaired VWF release.

    Abstract

    Extracellular Vimentin Is an Attachment Factor That Facilitates SARS-CoV-2 Entry into Human Endothelial Cells

    Researchers described the identification of vimentin, an intermediate filament protein widely expressed in cells of mesenchymal origin, as an important attachment factor for SARS-CoV-2 on human endothelial cells.
    [Proceedings of the National Academy of Sciences of the United States of America]

    Abstract

    Bivalent-Histone-Marked Immediate-Early Gene Regulation Is Vital for VEGF-Responsive Angiogenesis

    Scientists evaluated the global mapping of VEGF-mediated dynamic transcriptional events, focusing on major histone-code profiles using chromatin immunoprecipitation sequencing.

    PBLD Inhibits Angiogenesis via Impeding VEGF/VEGFR2-Mediated Microenvironmental Cross-Talk between HCC Cells and Endothelial Cells

    Phenazine biosynthesis-like domain-containing protein (PBLD) exerted an inhibitory effect on angiogenesis not only via blocking the VEGFR2 expression in endothelial cells, but also through downregulating HIF-1a-induced VEGF expression and secretion in hepatocellular carcinoma (HCC) cells.

    Abstract

    Genetic- and Diet-Induced Omega 3 Fatty Acid Enrichment Reduces TRPV4 Desensitization in Endothelial Cells to Enhance Vasodilation

    Transient receptor potential vanilloid 4 (TRPV4) enabled endothelial cells, smooth muscle cells, and perivascular neurons, to integrate hemodynamic forces to regulate systemic blood pressure.
    [Biophysical Journal]

    Abstract

    Apoptosis Induction in Human Lung and Colon Cancer Cells via Impeding VEGF Signaling Pathways

    Researchers assessed the suppressing effect of VGB4, a VEGF antagonist peptide with the binding ability to both VEGF receptor1 and VEGF receptor2, on VEGF-induced proliferation and migration of the human lung adenocarcinoma cell line A549 and the human colon adenocarcinoma cell line HT29.
