  1. 1. Diversification of TGF-β Signaling in Homeostasis and Disease

    Författare :Michael Vanlandewijck; Aristidis Moustakas; Carl-Henrik Heldin; Steven Dooley; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-β; signaling; SIK; EMT; polarity; Notch; ALK5; p21; growth arrest; Smurf; Smad7; receptor; SNF1LK; Molecular biology; Molekylärbiologi; Biology with specialization in Molecular Cell Biology; Biologi med inriktning mot molekylär cellbiologi;

    Sammanfattning : With the dawn of metazoans, the ability of cells to communicate with each other became of paramount importance in maintaining tissue homeostasis. The transforming growth factor β (TGF-β) signaling pathway, which plays important roles during embryogenesis and in the adult organism, signals via a heterodimeric receptor complex consisting of two type II and two type I receptors.

  3. 2. Molecular Regulation of Inflammation and Angiogenesis in the Tumor Microenvironment

    Författare :Lothar Dieterich; Anna Dimberg; Lena Claesson-Welsh; Jonas Fuxe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; stroma; glioma; alphaB-crystallin; HSPB5; cryab; myeloid cells; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; Cell and molecular biology; Cell- och molekylärbiologi; Molekylär medicin; Molecular Medicine;

    Sammanfattning : Tumor growth and progression not only depend on properties of the malignant cells but are strongly influenced by the tumor microenvironment. The tumor stroma consists of various cell types such as inflammatory cells, endothelial cells and fibroblasts, which can either inhibit or promote tumor growth. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Identification and Characterization of Proteins and MicroRNAs that Modulate Receptor Signaling, Vesicular Trafficking and Cell Migration in Vascular Cells

    Författare :Johan Heldin; Johan Kreuger; Jonas Fuxe; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Angiogenesis; cell migration; signaling; VEGF; FGD5; ExoC3L2; microRNA; RhoD; Molekylär cellbiologi; Molecular Cellbiology;

    Sammanfattning : Blood vessels deliver nutrients and oxygen to tissues. Importantly, the functions and growth of blood vessels are commonly altered in disease. The inside of all blood vessels are lined with endothelium, a thin specialized layer of endothelial cells that separate the blood from other tissues. LÄS MER

  7. 5. Metal homeostasis as critical determinant for cellular fitness

    Författare :Jutta Diessl; Sabrina Büttner; Rajini Rao; Stockholms universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; metal homeostasis; manganese toxicity; coenzyme Q synthesis; mitochondrial respiration; calcineurin signaling; Pmr1; SPCA1; calcium; survival; caloric restriction; Parkinson’s disease models; proteotoxicity; Pep4; cathepsin D; molekylär biovetenskap; Molecular Bioscience;

    Sammanfattning : Metals play a crucial role in cellular biology. Bulk and trace metals such as calcium and manganese regulate a plethora of cellular processes ranging from signaling and oxidative stress to proteostasis and energy metabolism. LÄS MER
