  1. 1. Neuropilin-1 regulation of tumor vascularization and growth

    Författare :Eric Morin; Lena Claesson-Welsh; Hellmut Augustin; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; Neuropilin-1; VEGFR2; tumor biology; pancreatic ductal adenocarcinoma; renal cell carcinoma; Medical Cell Biology; Medicinsk cellbiologi;

    Sammanfattning : Angiogenesis, the formation of new blood vessels from existing ones, is dysregulated during tumor progression as a result of chronic hypoxia and inflammation. Such alterations lead to a lack of vessel hierarchy, and the formation of poorly perfused, leaky and blunt-ended vessels, contributing to disease progression. LÄS MER

  3. 2. Vascular Endothelial Growth Factor (VEGF) and Peripheral Nerve Regeneration

    Författare :Mariann Sondell; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Schwann cell; SCG; rat; peripheral nerve regeneration; neuropilin-1; nerve repair; mouse; growth factor; flk-1; axonal outgrowth; DRG; VEGF; Animal physiology; Djurfysiologi;

    Sammanfattning : This thesis concerns vascular endothelial growth factor (VEGF) and its possible role as a neurotrophic factor. I have investigated the effect of VEGF on neurons in culture but also in vivo, following a crush lesion of the sciatic nerve, and following nerve repair. LÄS MER

  4. 3. VEGFR-2 in Endothelial Differentiation and Vascular Organization

    Författare :Dan Edholm; Lena Claesson-Welsh; Xiujuan Li; Victoria Bautch; Uppsala universitet; []
    Nyckelord :Molecular medicine; Embryonic stem; VEGFR-2; Flk1; KDR; VEGF; vasculogenesis; angiogenesis; embryoid body; Molekylärmedicin;

    Sammanfattning : The cardiovascular system is the first functional organ to develop during embryogenesis. As the embryo reaches above a certain size, passive diffusion of gases and nutrients is no longer compatible with efficient growth. LÄS MER

  5. 4. Activity-regulated retinoic acid signaling in olfactory sensory neurons

    Författare :Hande Login; Staffan Bohm; Mattias Alenius; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; mouse olfactory system; RA; neuronal activity; CNG; Cyp26B1; BACE1; Kirrel-2; molekylärbiologi; Molecular Biology;

    Sammanfattning : The aim of the studies included in the thesis is to better understand the interplay between neuronal activity-dependent gene regulation and the bioactive vitamin A metabolite all-trans-retinoic acid (RA) during postnatal development, refinement and maintenance of precise neuronal connectivity using the olfactory sensory neuron (OSN) in the olfactory epithelium (OE) of genetically modified mice as a model. We show that:Inhibition of RA receptor (RAR)-mediated transcription in OSNs reduces expression of the olfactory cyclic nucleotide-gated (CNG) ion channel, which is required for odorant receptor (OR)-mediated stimulus transduction.

  7. 5. Vascular metabolomics : gene regulation and role of VEGF-B in tissue fatty acid uptake

    Författare :Xun Wang; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Vascular endothelial growth factor B (VEGF‐B) belongs to the VEGF family, which constitutes of five mammalian members. VEGFs exert pivotal roles in the formation, development and maintenance of the vascular and lymphatic vessels. LÄS MER
