Analysis of freshly-isolated endothelial cells (EC) from umbilical arteries and veins and cultured arterial and venous ECs from different vascular regions. Culturing leads to loss of the arterial phenotype. Results provide insight into molecular mechanisms underlying arteriovenous EC heterogeneity.

(Submitter supplied) Endothelial cells (EC) lining arteries and veins have distinct molecular and functional signatures. The (epi)genetic regulatory mechanisms underlying this heterogeneity in human EC are incompletely understood. Using genome-wide microarray screening we established a specific fingerprint of freshly isolated arterial (HUAEC) and venous EC (HUVEC) from human umbilical cord comprising 64 arterial and 12 venous genes, representing distinct functions and pathways. more...

(Submitter supplied) COUP-TFII plays a critical role in angiogenesis during development. It has also been shown to suppress Notch signaling pathway to confer vein identity. However, the downstream targets and the mechanism mediate COUP-TFII function to regulate these processes remain elusive. To identify the downstream targets and the mechanism by which COUP-TFII regulates agiogenesis and vein specification, we knocked down COUP-TFII in HUVEC cells using COUP-TFII specific siRNA and used microarray analysis to identify downstream targets. more...

(Submitter supplied) Human Notch1 intracellular domain (NICD) was overexpressed in human primary lymphatic endothelial cells (LECs) for 10 and 24 hours by adenovirus. A GFP-control adenovirus-infected cells (24hours) and uninfected cells were also analysed as controls. Total RNAs were harvested and subjected to Affymetrix U133A microarray.

(Submitter supplied) Angiogenic homeostasis is maintained by a balance between vascular endothelial growth factor (VEGF) and Notch signalling in endothelial cells (ECs). We screened for molecules that might mediate the coupling of VEGF signal transduction with down-regulation of Notch signalling, and identified B-cell chronic lymphocytic leukemia/lymphoma6-associated zinc finger protein (BAZF). BAZF was induced by VEGF-A in ECs to bind to the Notch signalling factor CBF1, and to promote the degradation of CBF1 through polyubiquitination in a CBF1-cullin3 (CUL3) E3 ligase complex. more...

(Submitter supplied) Vascular permeability reflects changes in the function of the endothelium, its interendothelial junctions and transcellular delivery. Here, we show that common molecular mechanisms exist between VEGF and histamine in regulating vascular hyperpermeability. Crosstalk between downstream signaling of VEGF and histamine receptors are involved in calcium signaling and cell proliferation. Understanding the molecular mechanisms of vascular permeability is crucial in order to reduce vascular hyperpermeability and oedema in various pathological conditions and in VEGF therapy.

(Submitter supplied) Purpose: To analysis impacts of groucho and notch on transcription in Drosophila ISCs by mRNA-seq. Methods: mRNA-seq of RNA extracted from FACS sorted Drosophila ISCs. Results: Groucho loss in ISCs leads to disruption of lateral inhibition,and knocking down notch in ISCs down-regulates expression of e(spl) factors.

(Submitter supplied) Notch signaling regulates several cellular processes including cell fate decisions and proliferation in both invertebrates and mice. However, comparatively less is known about the role of Notch during early human development. Here, we examined the function of Notch signaling during hematopoietic lineage specification from human pluripotent stem cells (hPSCs) of both embryonic and adult fibroblast origin. more...

(Submitter supplied) Aims: Coronary vasculature formation is a critical event during cardiac development, essential for heart function throughout perinatal and adult life. However, current understanding of coronary vascular development has largely been derived from transgenic mouse models. The aim of this study was to characterise the transcriptome of the human fetal cardiac endothelium using single-cell RNA sequencing (scRNA-seq) to provide critical new insights into the cellular heterogeneity and transcriptional dynamics that underpin endothelial specification within the vasculature of the developing heart. more...

(Submitter supplied) To induce barrier of stem-cell derived endothelial cells in vitro cells have been transduced with a mixture of adenovirus overexpressing transcription factors with potential role in endothelial cell barrier stabilization. Adenoviruses overexpressing ETS1, SOX18 and SOX7 have been part of both transcription factor mixtures. As fourth transcription factor in the mixture included TAL1 while the other mixture included LEF1. more...

(Submitter supplied) The vascular system is locally specialized to accommodate widely varying blood flow and pressure and the distinct needs of individual tissues. The endothelial cells (ECs) that line the lumens of blood and lymphatic vessels play an integral role in the regional specialization of vascular structure and physiology. However, our understanding of EC diversity is limited. To explore EC specialization on a global scale, we used DNA microarrays to determine the expression profile of 53 cultured ECs. more...
