  2. 1. High-throughput screening using multicellular tumor spheroids to reveal and exploit tumor-specific vulnerabilities

    Abstract : High-throughput drug screening (HTS) in live cells is often a vital part of the preclinical anticancer drug discovery process. So far, two-dimensional (2D) monolayer cell cultures have been the most prevalent model in HTS endeavors. However, 2D cell cultures often fail to recapitulate the complex microenvironments of in vivo tumors. READ MORE

  4. 2. Modeling glioblastoma heterogeneity to decipher its biology

    Author : Yuan Xie; Lene Uhrbom; Massimo Squatrito; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioblastoma multiforme; biobank; GBM cells; cell of origin; LGR5; OPCs;

    Abstract : Glioblastoma multiforme (GBM) is the most common and lethal form of primary brain tumor that mainly affects adults. GBM displays remarkable intra- and inter-tumoral heterogeneity and contains a subpopulation of cells named glioma stem cells that is believed to be responsible for tumor maintenance, progression and recurrence.

  5. 3. TGF-beta signaling in cancer

    Author : Erik Johansson; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TGF-β; proliferation; cancer; tumor suppressor; diffuse-type gastric carcinoma; neuroblastoma; nuclear receptor TLX; cancer stem cell; angiogenesis; ABCG2; VHL; HIF2α; hypoxia; Smad3;

    Abstract : Transforming Growth Factor Beta (TGF-β) is a cytokine regulating a wide range of cellular processes such as proliferation, differentiation, and migration. At the early stages of cancer development TGF-β functions as a tumor suppressor, mainly due to its inhibitory effect on cellular growth, but during cancer progression, mutations in TGF-β signal components switches TGF-β into a promoter of cancer cell proliferation, survival and metastasis.

  6. 4. Hormonal regulation of liver and tumor growth

    Author : Ville Wallenius; Göteborgs universitet; []
    Keywords : 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;

    Abstract : 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.

  7. 5. Cellular Origin and Development of Glioma

    Author : Nanna Lindberg; Lene Uhrbom; Bengt Westermark; Kristian Pietras; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Glioma; brain tumor; PDGF; RCAS TV-A; cell of origin; glial cell; oligodendrocyte progenitor cell; DNA repair; homology-directed repair; RAD51; angiogenesis; histidine-rich glycoprotein; Morphology; cell biology; pathology; Morfologi; cellbiologi; patologi; Molecular Medicine; molekylär medicin genetik och patologi ;

    Abstract : Gliomas are the most common primary tumors of the central nervous system believed to arise from glial cells. Invasive growth and inherent propensity for malignant progression make gliomas incurable despite extensive treatment. READ MORE
