  2. 1. Regulation of cell polarity and invasion by TGF-β and BMP signaling

    Author : Mahsa Shahidi Dadras; Aristidis Moustakas; Petra Knaus; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Cancer; cancer stem cells; invasion; metastasis; polarity; TGF-β signaling.;

    Abstract : Transforming growth factor β (TGF-β) and bone morphogenetic protein (BMP) signaling pathways are involved in many physiological processes during embryonic and adult life. TGF-β promotes epithelial to mesenchymal transition (EMT). We identified a gene target of TGF-β signaling, encoding the salt-inducible kinase 1 (SIK1). READ MORE

  4. 2. Invasion of top and intermediate consumers in a size structured fish community

    Author : Per Ask; Lennart Persson; Daniel E Schindler; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Invasion; intraguild predation; size-structure; cannibalism; climate; temperature; Arctic char; ninespine stickleback; Freshwater ecology; Limnisk ekologi; biology; biologi;

    Abstract : In this thesis I have investigated the effects of invading top and intermediate consumers in a size-structured fish community, using a combination of field studies, a lake invasion experiment and smaller scale pond and aquaria experiments. The lake invasion experiment was based on introductions of an intermediate consumer, ninespine stickleback (Pungitius pungitius L. READ MORE

  5. 3. Invasion and Proliferation in Malignant Cells

    Author : Sofie Svensson Månsson; Malmö Patologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cancerology; oncology; Cytology; breast cancer; squamous cell carcinoma; basal cell carcinoma; p16; proliferation; invasion; Cytologi; onkologi; cancer;

    Abstract : Two key events in the oncogenic process of tumor cells are to acquire uncontrolled proliferation and invasive properties. This allows the tumor to grow and invade beyond the tissue from which the tumor cells originate. READ MORE

  6. 4. Molecular mechanisms of nerve-tumor interactions : the intersection of cancer and neurodevelopment

    Author : Luz Maria Gonzalez-Castrillon; Sara I Wilson; Daniel Öhlund; Nisha D’Silva; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Perineural invasion; cancer; PDAC; axonogenesis; neurodevelopment; spinal cord; axon guidance; bioinformatics.; biomedical laboratory science; biomedicinsk laboratorievetenskap;

    Abstract : A wide range of cancers throughout the body are characterized by high nerve density and invasion of cancer cells within the nerves, a process called perineural invasion (PNI). Work in the field has shown that blocking nerves in organs with tumors leads to improved disease outcomes suggesting that finding ways to block tumor nerves could lead to new treatment approaches.

  7. 5. Glioma as an Ecosystem : Studies of Invasion, Onco-miR Addiction and Mast Cell Infiltration

    Author : Jelena Põlajeva; Bengt Westermark; Ingemar Ernberg; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; glioblastoma; mast cell; miR-21; RAP1; CXCL12; SOX2;

    Abstract : Despite recent advances in oncology and extensive research efforts, gliomas remain essentially incurable. Glioblastoma multiforme (GBM, WHO grade IV) is the most common glioma and may arise de novo or progress from a lower-grade lesion. GBM is characterized by invasive growth, aberrant angiogenesis and necrosis. READ MORE
