(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Aim: For isolation of exosomes, differential ultracentrifugation and an isolation kit from a major vendor were compared. Materials & methods: ‘Case study’ exosomes isolated from patient-derived cells from glioblastoma ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Histopathology is a widely used approach to evaluate effects of endocrine-active chemicals in the thyroid. However, effects at an ultrastructural level have hardly been examined in fish thyroids. In the present study, ...
-
(Master thesis / Masteroppgave, 2016)Fransicella tularensis (F.t.) is a facultative intracellular pathogen that escapes from the phagosome into the host cell cytosol in order to survive and proliferate. F.t. subspecies tularensis and holartica are the causative ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2017)Lysine methylation is an important and much-studied posttranslational modification of nuclear and cytosolic proteins but is present also in mitochondria. However, the responsible mitochondrial lysine-specific methyltransferases ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The toxicity resulting from exposure to oil droplets in marine fish embryos and larvae is still subject for debate. The most detailed studies have investigated the effects of water-dissolved components of crude oil in water ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)The emergence of multicellular animals was associated with an increase in phenotypic complexity and with the acquisition of spatial cell differentiation and embryonic development. Paradoxically, this phenotypic transition ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Transmembrane proteins in the outer membrane of Gram-negative bacteria are almost exclusively β-barrels. They are inserted into the outer membrane by a conserved and essential protein complex called the BAM (for β-barrel ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Here, we demonstrate a contrasting effect of terrestrial coloured dissolved organic material on the secondary production of boreal nutrient poor lakes. Using fish yield from standardised brown trout gill-net catches as a ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2013)Genes encoding the major histocompatibility complex (MHC) have been thought to play a vital role in the adaptive immune system in all vertebrates. The discovery that Atlantic cod (Gadus morhua) has lost important components ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2015)The neonatal Fc receptor (FcRn) was first found to be responsible for transporting antibodies of the immunoglobulin G (IgG) class from the mother to the fetus or neonate as well as for protecting IgG from intracellular ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Genetic affiliation, nuclear DNA content, and gamete functioning were examined in small salt marsh Fucus from three localities in western Ireland. Individuals with small and dioecious receptacles were found at all localities, ...
-
(Doctoral thesis / Doktoravhandling, 2019)In this work Ignacio Cuervo and co-workers have studied different aspects of the transcriptional regulating processes implicated in embryonic stem cell differentiation and in the regulation and dysregulation of cancer ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Urbanization and rural–urban migration are two factors driving global patterns of disease and mortality. There is significant concern about their potential impact on disease burden and the effectiveness of current control ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)Assessing phytoplankton diversity is of primary importance for both basic and applied ecological studies. Following the advances in molecular methods, phytoplankton studies are switching from using classical microscopy to ...
-
(Master thesis / Masteroppgave, 2015)The vertebrate immune system is an enormously complex arrangement of a large number of interdependent cell types, responsible for fending off harmful invasive organisms as well as aberrant cells within the host itself. The ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2014)RNA-Seq has become a widely used method to study transcriptomes, and it is now possible to perform RNA-Seq on almost any sample. Nevertheless, samples obtained from small cell populations are particularly challenging, as ...
-
(Master thesis / Masteroppgave, 2019)The use of remote video traps is a popular method of studying animal behavior in nature. It is an efficient, inexpensive and non-invasive way of obtaining samples from the field. In this study, I built and used video traps ...

Utilization of autophagy in the antigen donor cell for enhanced priming of Gag-p24-specific CD8+ T cell responsesRestricted Access (Master thesis / Masteroppgave, 2013)
-
(Master thesis / Masteroppgave, 2016)Desto tidligere en kreftsykdom blir oppdaget, desto større er sjansen for overlevelse. De fleste kreftrelaterte dødsfall er forårsaket av metastaser. Det er derfor viktig å kunne detektere tilstedeværelse av disse så tidlig ...

Validation of DNA metabarcoding as a tool for diet analysis in reindeer (Rangifer tarandus tarandus L.)Restricted Access (Master thesis / Masteroppgave, 2019)Free-ranging reindeer (Rangifer tarandus L.) eat a diverse diet of graminoids, herbs, shrubs, woody plants, mushroom, lichen and mosses. DNA metabarcoding is an established method in dietary studies and through e.g. ...
