Fibroblast α11β1 Integrin Regulates Tensional Homeostasis in Fibroblast/A549 Carcinoma Heterospheroids
(Peer reviewed; Journal article, 2014-07-30)We have previously shown that fibroblast expression of α11β1 integrin stimulates A549 carcinoma cell growth in a xenograft tumor model. To understand the molecular mechanisms whereby a collagen receptor on fibroblast can ... -
Automated Quantification and Integrative Analysis of 2D and 3D Mitochondrial Shape and Network Properties
(Peer reviewed; Journal article, 2014-07-02)Mitochondrial morphology and function are coupled in healthy cells, during pathological conditions and (adaptation to) endogenous and exogenous stress. In this sense mitochondrial shape can range from small globular ... -
Sleep and protein synthesis-dependent synaptic plasticity: impacts of sleep loss and stress
(Peer reviewed; Journal article, 2014-01-21)Sleep has been ascribed a critical role in cognitive functioning. Several lines of evidence implicate sleep in the consolidation of synaptic plasticity and long-term memory. Stress disrupts sleep while impairing synaptic ... -
Molecular composition and function of integrin-based collagen glues—Introducing COLINBRIs
(Peer reviewed; Journal article, 2014-08)Background: Despite detailed knowledge about the structure and signaling properties of individual collagen receptors, much remains to be learned about how these receptors participate in linking cells to fibrillar collagen ... -
Normalized gradient fields for nonlinear motion correction of DCE-MRI time series
(Peer reviewed; Journal article, 2014-04)Dynamic MR image recordings (DCE-MRI) of moving organs using bolus injections create two differenttypes of dynamics in the images: (i) spatial motion artifacts due to patient movements, breathing andphysiological pulsations ... -
NMDA receptor-dependent regulation of miRNA expression and association with Argonaute during LTP in vivo
(Peer reviewed; Journal article, 2014-01-13)microRNAs (miRNAs) are major regulators of protein synthesis in the brain. A major goal is to identify changes in miRNA expression underlying protein synthesis-dependent forms of synaptic plasticity such as long-term ... -
Functional studies of tyrosine hydroxylase missense variants reveal distinct patterns of molecular defects in dopa-responsive dystonia
(Peer reviewed; Journal article, 2014-06-03)Congenital tyrosine hydroxylase deficiency (THD) is found in autosomal-recessive Dopa-responsive dystonia and related neurological syndromes. The clinical manifestations of THD are variable, ranging from early-onset lethal ... -
In vitro treatment of melanoma brain metastasis by simultaneously targeting the MAPK and PI3K signaling pathways
(Peer reviewed; Journal article, 2014-05-16)Malignant melanoma is the most lethal form of skin cancer, with a high propensity to metastasize to the brain. More than 60% of melanomas have the BRAFV600E mutation, which activates the mitogen-activated protein kinase ... -
Tunneling nanotubes: Diversity in morphology and structure
(Peer reviewed; Journal article, 2014-02-06)Tunneling nanotubes (TNTs) are recently discovered thin membranous tubes that interconnect cells. During the last decade, research has shown TNTs to be diverse in morphology and composition, varying between and within cell ... -
Segmentation-Driven Image Registration-Application to 4D DCE-MRI Recordings of the Moving Kidneys
(Peer reviewed; Journal article, 2014-04-01)Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) of the kidneys requires proper motion correction and segmentation to enable an estimation of glomerular filtration rate through pharmacokinetic modeling. ... -
The microenvironment in human ovarian carcinoma - characterization through proteomic analysis of tissue interstitial fluid
(Doctoral thesis, 2013-10-11)The interstitial fluid of tissues and that of tumors in particular, represents the secretome and is thus a valuable source of tissue-specific proteins. The differential expression of proteins that are secreted in tumor ... -
Altered DNA methylation profile in Norwegian patients with Autoimmune Addison’s Disease
(Peer reviewed; Journal article, 2014-03-22)Autoimmune Addison's Disease (AAD) is an endocrine and immunological disease of uncertain pathogenesis resulting from the immune system's destruction of the hormone producing cells of the adrenal cortex. The underlying ... -
Quantification of the concentration gradient of biomarkers between ovarian carcinoma interstitial fluid and blood
(Peer reviewed; Journal article, 2014-12)Background: Tumor interstitial fluid (TIF) rather than plasma should be used in cancer biomarker discovery because of the anticipated higher concentration of locally produced proteins in the tumor microenvironment. ... -
Enhanced protein synthesis and secretion using a rational signal-peptide library approach as a tailored tool
