  1. 16. Molecular and Cellular Complexity of Glioma : Highlights on the Double-Edged-Sword of Infiltration Versus Proliferation and the Involvement of T Cells

    Författare :Demet Çağlayan; Bengt Westermark; Maria Ferletta; Ana Martin-Villalba; Uppsala universitet; []

    Sammanfattning : Glioblastoma multiforme (GBM), the most common and malignant brain tumor, is characterized by high molecular and cellular heterogeneity within and among tumors. Parameters such as invasive growth, infiltration of immune cells and endothelial proliferation contribute in a systemic manner to maintain the malignancy. LÄS MER

    Sammanfattning : The aim of this thesis is to model and describe dynamical events for biological cells using statistical and mathematical tools. The thesis includes five papers that all relate to stochastic modelling of cells. LÄS MER

  4. 18. Hormonal regulation of liver and tumor growth

    Författare :Ville Wallenius; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Liver; cytokine; interleukin-6; tumor necrosis factor; primary liver growth promoter; cyproterone acetate; nafenopin; hepatocyte growth factor; HGF receptor; tumor; sarcoma; N-terminal; truncated;

    Sammanfattning : The aims of this thesis were to investigate the regulatory functions of interleukin-6 (IL-6) and tumor necrosis factor-a (TNF-a) on liver growth, and the importance of hepatocyte growth factor (HGF) and the HGF receptor (Met) for growth of mesenchyme-derived tumors. The studies on different types of liver growth, measured as weight, DNA and protein content, and DNA synthesis, were performed on mice lacking the IL-6 or the TNF receptor-1 gene back-crossed to the C57bl/6 strain.

  5. 19. 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

  7. 20. The role of transforming growth factor‐β signaling and hypoxia‐inducible factors in renal cell carcinoma

    Författare :Pramod Mallikarjuna; Maréne Landström; Börje Ljungberg; Raviprakash Tumkur Sitaram; Anders Bjartell; Umeå universitet; []

    Sammanfattning : Renal cell carcinoma (RCC) is the cancer of the kidneys; about 1100 patients with RCC are diagnosed in Sweden each year. RCC can be classified into several subtypes, clear cell renal cell carcinoma (ccRCC) is most common accounting to about 70% of all RCCs, and also the most lethal; papillary renal cell carcinoma (pRCC) accounts to about 10%‐15%, while chromophobe renal cell carcinoma (chRCC) accounts to about 5% of all RCCs.
