U-251 revisited: genetic drift and phenotypic consequences of long-term cultures of glioblastoma cells
(Peer reviewed; Journal article, 2014-08)It is well known that in vitro subculture represents a selection pressure on cell lines, and over time this may result in a genetic drift in the cancer cells. In addition, long-term cultures harbor the risk of cross-contamination ... -
Exploring the anti-leukemic effect of the combination treatment with Valproic acid, Lonidamine and Mycophenolate mofetil in acute myeloid leukemia
(Master thesis, 2015-06-01)An accumulation of immature myeloid progenitor cells at the expense of normal hematopoietic precursors characterizes the aggressive heterogeneous cancer acute myeloid leukemia (AML). It affects the bone marrow and peripheral ... -
EEG Analysis in Adults with Attention-Deficit-Hyperactivity-Disorder. Resting state and behavioural data analysis
(Master thesis, 2015-05-31)Introduction: Adults with attention-deficit/hyperactivity disorder (ADHD) are examined by electroencephalography (EEG). EEG is a non-invasive method to measure brain activity indirectly, by measuring voltage changes on the ... -
Voxel dimension optimization for probabilistic tractography in rat brain using 7T scanner
(Master thesis, 2015-06-01)Brain connectivity is an increasingly important research field within neuroscience. Using MRI technology it is now possible to measure diffusion to approximate the location of anatomical tracts in the brain or correlate ... -
Experimental modeling and novel therapeutic strategies in melanoma brain metastasis
(Doctoral thesis, 2015-06-09)Melanoma patients carry a high risk of developing brain metastases and improvements in survival are still measured in weeks or months. The aim of this thesis was to study the biology of melanoma brain metastasis and find ... -
Genome-wide analysis of attention deficit hyperactivity disorder in Norway
(Peer reviewed; Journal article, 2015-04-13)Background Attention deficit hyperactivity disorder (ADHD) is a highly heritable neuropsychiatric condition, but it has been difficult to identify genes underlying this disorder. This study aimed to explore genetics of ... -
Cyanobacteria from terrestrial and marine sources contain apoptogens able to overcome chemoresistance in acute myeloid leukemia cells
(Peer reviewed; Journal article, 2014-04-03)In this study, we investigated forty cyanobacterial isolates from biofilms, gastropods, brackish water and symbiotic lichen habitats. Their aqueous and organic extracts were used to screen for apoptosis-inducing activity ... -
HAMLET forms annular oligomers when deposited with phoshpolipid monolayers
(Peer reviewed; Journal article, 2012-04)Recently, the anticancer activity of human α-lactalbumin made lethal to tumor cells (HAMLET) has been linked to its increased membrane affinity in vitro, at neutral pH, and ability to cause leakage relative to the inactive ... -
Dendritic cells loaded with tumor antigens and a dual immunostimulatory and anti-IL-10 specific siRNA can prime T lymphocytes against leukemic cells
(Peer reviewed; Journal article, 2009-12)Vaccines using dendritic cells (DCs) harboring leukemic antigens to stimulate T cells is a possible treatment of acute myeloid leukemia (AML). Limitations of breaking tolerance to leukemic cells and lack of specific ... -
Cancer stem cells as mediators of treatment resistance in brain tumors: Status and controversies
(Peer reviewed; Journal article, 2007-11)Malignant primary brain tumors are characterized by a short median survival and an almost 100% tumorrelated mortality. Despite the addition of new chemotherapy regimes, the overall survival has improved marginally, and ... -
The 14-3-3 proteins in regulation of cellular metabolism
(Peer reviewed; Journal article, 2011-09)Thirty years ago, it was discovered that 14-3-3 proteins could activate enzymes involved in amino acid metabolism. In the following decades, 14-3-3s have been shown to be involved in many different signaling pathways that ... -
Increased plasma colloid osmotic pressure facilitates the uptake of therapeutic macromolecules in a xenograft tumour model
(Peer reviewed; Journal article, 2009-08)Elevated tumor interstitial fluid pressure (TIFP) is a characteristic of most solid tumors. Clinically, TIFP may hamper the uptake of chemotherapeutic drugs into the tumor tissue reducing their therapeutic efficacy. In ... -
Lowering of tumor interstitial fluid pressure reduces tumor cell proliferation in a xenograft tumor model
(Peer reviewed; Journal article, 2006-02)High tumor interstitial fluid pressure (TIFP) is a characteristic of most solid tumors. TIFP may hamper adequate uptake of macromolecular therapeutics in tumor tissue. In addition, TIFP generates mechanical forces affecting ... -
Gamma knife surgery as monotherapy with clinically relevant doses prolongs survival in a Human GBM Xenograft Model
(Peer reviewed; Journal article, 2013)Object. Gamma knife surgery (GKS) may be used for recurring glioblastomas (GBMs). However, patients have then usually undergone multimodal treatment, which makes it difficult to specifically validate GKS independent of ... -
Age-dependent association between protein expression of the embryonic stem cell marker Cripto-1 and survival of glioblastoma patients
(Peer reviewed; Journal article, 2013-12)Exploring the re-emergence of embryonic signaling pathways may reveal important information for cancer biology. Nodal is a transforming growth factor-β (TGF-β)-related morphogen that plays a critical role during embryonic ... -
Structural and thermodynamic insight into phenylalanine hydroxylase from the human pathogen Legionella pneumophila
(Peer reviewed; Journal article, 2013-08-19)Phenylalanine hydroxylase from Legionella pneumophila (lpPAH) has a major functional role in the synthesis of the pigment pyomelanin, which is a potential virulence factor. We present here the crystal structure of lpPAH, ... -
Release of tensile strain on engineered human tendon tissue disturbs cell adhesions, changes matrix architecture, and induces an inflammatory phenotype
(Peer reviewed; Journal article, 2014-01-21)Mechanical loading of tendon cells results in an upregulation of mechanotransduction signaling pathways, cell-matrix adhesion and collagen synthesis, but whether unloading removes these responses is unclear. We investigated ... -
