  1. 1. THE ROLE OF BMP SIGNALING AND ENDOGLIN IN REGULATION OF HEMATOPOIESIS

    Author : Sofie Singbrant; Avdelningen för molekylärmedicin och genterapi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-beta superfamily signaling; Conditional knockout mouse; Hematopoietic Stem Cell; Hematopoiesis; Endoglin; BMP;

    Abstract : Hematopoiesis, the formation of blood cells, ultimately depends on a rare population of hematopoietic stem cells (HSCs), which can both self-renew to maintain the HSC pool, and differentiate into all mature blood lineages. HSC fate decisions are governed by a complex combination of numerous signals, although the molecular mechanisms are not fully understood. READ MORE

  2. 2. Heparan sulfate dependent cell signaling and associated pathophysiology : Implications in tumorigenesis and embryogenesis

    Author : Tahira Batool; Jin-Ping Li; Aristidis Moustakas; Liliana Schaefer; Ingvar Ferby; Michael Welsh; Anders Malmström; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Heparanase; Glucuronyl-C5 epimerase; Heparan Sulfate; Heparin; Lung Cancer; Cancer cell Singling; TGF-Beta; BMP; VEGF; Notch Signaling; Tumor growth; Metastasis; embryonic development; Medical Biochemistry; Medicinsk biokemi;

    Abstract : Heparan sulfate proteoglycans (HSPGs) consist of a protein core to which several linear, negatively charged heparan sulfate (HS) chains are covalently attached. HSPGs are expressed on the cell surface and in the extra-cellular matrix (ECM) where they have diverse biological functions, for example co-receptor functions. READ MORE

  3. 3. BMP - a key signaling molecule in specification and morphogenesis of sensory structures

    Author : Vijay Kumar Jidigam; Lena Gunhaga; Jonas von Hofsten; Richard A. Lang; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; BMP signaling; Placode morphogenesis; lens; retina; olfactory; otic; Developmental Biology; miljömedicinsk utvecklingsbiologi;

    Abstract : Cranial placodes are transient thickenings of the vertebrate embryonic head ectoderm that will give rise to sensory (olfactory, lens, and otic) and non-sensory (hypophyseal) components of the peripheral nervous system (PNS). In most vertebrate embryos, these four sensory placodes undergo invagination. READ MORE

  4. 4. Studies of PDGF receptor signaling in vitro and in vivo

    Author : Maria Tsioumpekou; Carl-Henrik Heldin; Jean-Baptiste Demoulin; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; PDGF; signaling; cancer; Erk5; kinase; Cbl; ubiquitination; deubiquitinase; pericytes; tumor growth; angiogenesis; low molecular weight inhibitors;

    Abstract : Platelet-derived growth factor receptor (PDGFR) signaling is essential for proliferation, migration and survival of cells of mesenchymal origin; however, its deregulation has been associated with various diseases, including cancer. The aim of this thesis was to clarify the molecular mechanisms of PDGFR signaling regulation. READ MORE

  5. 5. Signaling mechanisms underlying neural stem cell differentiation. Implications of BMPs, retinoids, and MAP kinases

    Author : Roland Faigle; Göteborgs universitet; []
    Keywords : neural stem cells; differentiation; BMP; ASK1; p38 MAP kinase; CNTF; retinoic acid;

    Abstract : Introduction: Neural stem cells are proliferating cells, derived from the nervous system with the ability to give rise to neurons, astrocytes, and oligodendrocytes. The molecular events and signaling pathways regulating neural stem cell differentiation are largely unknown. READ MORE
