    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

  2. 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.

    Abstract : Anaplastic thyroid carcinoma (ATC) is an aggressive malignancy in man with stromal fibrosis as one of the main features. Carcinoma cells synthesized no or little collagen I protein. READ MORE

  4. 4. The role of Smad7 and TRAF6 in Prostate Cancer Cell Invasion, Migration and Survival

    Author : Maria Ekman; Marene Landström; Carl-Henrik Heldin; Jonas Fuxe; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; TGF-beta; cell migration; invasion; apoptosis; Smad7; APC; ATM; TRAF6; p53; PC3U; Medical Cell Biology; Medicinsk cellbiologi;

    Abstract : Transforming growth factor (TGF) β is a tumor suppressor during early tumor development, by inhibiting proliferation and inducing apoptosis. At later stages of cancer, it becomes a tumor promoter, and promotes tumor cell migration and invasion. TGFβ signals via its type II and type I receptors to several downstream signaling pathways.

  5. 5. Studies on Tissue Factor with Focus on Cell Signaling and Cancer

    Author : Oskar Eriksson; Agneta Siegbahn; Lina Badimon; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Tissue Factor; blood coagulation; cell signaling; protease; mass spectrometry; immunohistochemistry; colorectal cancer; apoptosis; Eph receptor; Klinisk kemi; Clinical Chemistry; Molekylär cellbiologi; Molecular Cellbiology;

    Abstract : This thesis have explored the functions of the protein Tissue Factor (TF), which together with its ligand coagulation factor VII/VIIa (FVII/FVIIa) forms a proteolytic complex that functions in initiation of blood coagulation and activation of cell signaling.In paper I, the mechanisms behind the observation that TF/FVIIa signaling protects cells from apoptosis were further investigated.
