Blood 20100812 19

Sprouting of developing blood vessels is mediated by specialized motile endothelial cells localized at the tips of growing capillaries. Following behind the tip cells, endothelial stalk cells form the capillary lumen and proliferate. Expression of the Notch ligand Delta-like-4 (Dll4) in tip cells suppresses tip cell fate in neighboring stalk cells via Notch signaling. In DLL4(+/-) mouse mutants, most retinal endothelial cells display morphologic features of tip cells. We hypothesized that these ...[more]

Expression analysis of mouse retinas after treatment with VEGF-A or Dll4-Fc.

Project description:Transcriptional profiling of retinas extracted from mouse pups 24 hours after IVT injection (at P8) of 1 microgram VEGFA, 4 micrograms Dll4-Fc, or 4 microgram hFc alone. Goal was to determine the mechanism by which inhibiting Dll4/Notch pathway is vasoprotective during retinal development. Three-condition experiment: VEGF-A treated vs hFc, Dll4-Fc vs hFc. Four replicates each for Dll4-Fc and hFc, five for VEGF-A.

Transcription profiling of human LEC cells reveals KSHV manipulates notch signaling by upregulating Dll4 and JAG1 to alter cell cycle gene expression in

Project description:Kaposi sarcoma is the most common cancer in AIDS patients and is typified by red skin lesions. The disease is caused by the KSHV virus (HHV8) and is recognizable by its distinctive red skin lesions. The lesions are KSHV infected spindle cells, most commonly the lymphatic endothelial and blood vessel endothelial cells (LEC and BEC), plus surrounding stroma. Here we examine KSHVs modulation of Notch signaling using wild-type LEC cells co-cultured with DLL4 and JAG1 expressing LEC cells. Experiment Overall Design: There are 1) n=2 of LEC control cells co-cultured with pSIN expressing LEC, 2) n=3 of LEC co-cultured with pSIN-Dll4 expressing LEC, and 3) n=3 of LEC co-cultured with pSIN-JAG1 expressing LEC.

Non-coding small RNA profiling by high throughput sequencing of bovine primary retinal microvascular endothelial cells

Project description:The aim of this study was to identify and quantify microRNAs and other small regulatory RNAs expressed in primary retinal microvascular endothelial cells (RMECs) using deep sequencing. RMECs were isolated, RNA extracted, a small RNA library prepared and deep sequencing performed. A total of 6.8 million reads were mapped to 250 known microRNAs in miRBase (release 16). Several novel microRNAs and multiple new members of the miR-2284/2285 family were detected. Several ~30 nucleotide sno-miRNAs were identified, with the most highly expressed being derived from snoRNA U78. Highly expressed microRNAs previously associated with endothelial cells included miR-126 and miR-378, but the most highly expressed was miR-21, comprising more than one third of all mapped reads. The independence from prior sequence knowledge provided by deep sequencing facilitates analysis of novel microRNAs and other small RNAs. This approach also enables quantitative evaluation of microRNA expression, which has highlighted the predominance of a small number of microRNAs in RMECs. Further characterisation of the functions of the highly expressed microRNAs will provide insights into endothelial biology. Single sample of primary cell culture

Deubiquitinase USP10 regulates Notch signaling in the endothelium

Project description:Notch signaling is critical for vascular morphogenesis by co-determining the sprouting behavior of endothelial cells. Here, we investigate the function of ubiquitin-specific peptidase 10 (USP10) in regulation of the turnover of the NOTCH1 intracellular domain. HUVEC were transfected with scrambled or USP10 targeting siRNA and then stimulated by treatment with DLL4 or control. RNA for analysis was isolated after 24 hours of DLL4 stimulation.

Rat retina and optic nerve LC-MS/MS

Project description:Various retinal disorder such as glaucomatous, retinal ischemia reperfusion, and traumatic optic neuropathy, are involved in the pathogenesis of neurodegeneration via glutamate exicitotoxicity. However, the proteomic characteristics and modulation of the neural-microenvironment with NMDA-induced neurodegeneration in retina and optic nerve remain partly understood. We established a protein sketch of NMDA-induced injury by comparing the proteomes of the PBS-operated, NMDA-operated and control groups. We carried out mass spectrometry-based label-free quantitative proteomics to investigate the exicitotoxic neurodegeneration mechanisms and identify key proteins that regulated neural cell death related signaling pathway in retina and optic nerve spatially. Using LC-MS/MS proteomics analysis, in total, we identified 3532 proteins in retina, 2593 proteins in optic nerve. According to Gene Ontology (GO), Kyoto Encyclopedia of Genes and Genomes (KEGG), the protein changes and energy metabolism in retina and optic nerve tissue were comprehensively evaluated.

Gene expression changes in the retina following human neural progenitor cell injection into a rodent model for retinal degeneration

Project description:The goal of this study is to compare gene expression changes in retinal degenerate Royal College of Surgeons (RCS) rats following an injection of human neural progenitor cells (hNPCs) using RNA-seq, as compared to RCS rats receiving a sham surgery and wild-type Long Evans rats. These changes may lead to understanding of the therapeutic potential of hNPCs in inducing photoreceptor survival and visual function preservation.

Molecular mechanism underline immune cell type population shift upon anti-DLL4 treatment

Project description:Molecular mechanism underline immune cell type population shift upon anti-DLL4 treatment C57BL/6 mice were injected with anti-DLL4, or an isotype control antibody as controls. Two weeks later mice were sacrificed, and thymi was harvested from 4 anti-DLL4 and 4 control animals. Total thymocytes, DN cells (CD4-CD8-) and DN1(CD4-CD8- CD44+CD25-) cells were isolated. Samples included in this data set are: 3 Thymocytes-anti-DLL4; 3 Thymocytes-isotype control; 3 DN1-anti-DLL4; 2 DN1-isotype controls; 3 DN-anti-DLL4; 3 DN-isotyoe control.

Endothelial inhibition of the glycolytic activator PFKFB3 induces tumor vessel normalization, impairs metastasis and improves chemotherapy

Project description:Abnormal tumor vessels promote metastasis and impair chemotherapy. Hence, tumor vessel normalization (TVN) by targeting endothelial cells (ECs) is emerging as anti-cancer treatment. Here, we show that tumor ECs (TECs) have a hyper-glycolytic metabolism, shunting glycolytic intermediates to nucleotide synthesis. EC haplo-deficiency or blockade of the glycolytic activator PFKFB3 did not affect tumor growth, but reduced cancer cell intra- and extravasation and metastasis by normalizing tumor vessels, which improved vessel maturation and perfusion. Mechanistically, PFKFB3 inhibition tightened the vascular barrier by reducing VE-cadherin endocytosis in ECs and rendering glycolytic pericytes more quiescent; it also lowered the expression of cancer cell adhesion molecules in ECs. Additionally, PFKFB3-blockade treatment improved chemotherapy. Considering TEC metabolism for anti-cancer treatment might thus merit further attention.
