Epiregulin (EREG) associated with disc herniation induces spontaneous activity in the pain pathways. (Master thesis / Masteroppgave, 2016)Low back pain and sciatica after disc herniation may be caused by mechanical compression of the nerve roots, but also by the release of pro-inflammatory agents and growth factors from the nucleus pulposus (NP) of the ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)Phenotypic diversity is an important trait of bacterial populations and can enhance fitness of the existing genotype in a given environment. To characterize different subpopulations, several studies have analyzed differential ...

Er avvikende celler av Prymnesium polylepis mer motstandsdyktige mot virusangrep enn typiske celler? (Master thesis / Masteroppgave, 2014)Prymnesium polylepis er en svepeflagellat med to ulike morfologiske flagellatstadier som består av avvikende eller typiske celler. Kulturer med typiske celler er haploide, og kulturer med avvikende celler kan enten være ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)Although lysosomes perform a number of essential cellular functions, damaged lysosomes represent a potential hazard to the cell. Such lysosomes are therefore engulfed by autophagic membranes in the process known as lysophagy, ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)The multisubunit endosomal sorting complex required for transport (ESCRT) machinery is a key regulator of cellular membrane dynamics. Initially characterized in the budding yeast Saccharomyces cerevisiae for its involvement ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Inferring the evolutionary history of cognitive abilities requires large and diverse samples. However, such samples are often beyond the reach of individual researchers or institutions, and studies are often limited to ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Incomplete lineage sorting (ILS) can lead to biased divergence time estimates. To explore if and how ILS has influenced the results of a recent worldwide phylogeny of three-spined sticklebacks (Gasterosteus aculeatus), we ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Thermal melanism theory states that dark-colored ectotherm organisms are at an advantage at low temperature due to increased warming. This theory is generally supported for ectotherm animals, however, the function of colors ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2014)The vertical distribution and migration of plankton organisms may have a large impact on their horizontal dispersal and distribution, and consequently on trophic interactions. In this study we used video-net profiling to ...
