Role of FOXA genes in maintaining transformed phenotype in human bronchial epithelial cells - Construction of a CRISPR-Cas9 vector system for site-specific integration of FOXA1
(Master thesis, 2015)Lung cancer is the number one cause of worldwide cancer deaths for men, and second cause of cancer deaths for women. Tobacco smoking is strongly associated with lung cancer, and carcinogenic compounds inhaled when smoking ... -
Role of GCN5 and PCAF in the B Lymphocyte Development
(Master thesis, 2018)DNA in our cells is constantly damage by internal and external factors generating DSBs. To maintain genome stability, cells have developed various DNA damage surveillance and repair mechanisms to prevent chromosomal ... -

RPA2 winged-helix domain facilitates UNG-mediated removal of uracil from ssDNA; implications for repair of mutagenic uracil at the replication fork
(Journal article; Peer reviewed, 2021)Uracil occurs at replication forks via misincorporation of deoxyuridine monophosphate (dUMP) or via deamination of existing cytosines, which occurs 2-3 orders of magnitude faster in ssDNA than in dsDNA and is 100% miscoding. ... -
RpoS controls the expression and the transport of the AlgE1-7 epimerases in Azotobacter vinelandii
(Journal article; Peer reviewed, 2018)Azotobacter vinelandii produces differentiated cells, called cysts, surrounded by two alginate layers, which are necessary for their desiccation resistance. This alginate contains variable proportions of guluronate residues, ... -
Safe production of farmed Atlantic salmon (Salmo salar)
(Research report, 2010)This work contains a review of the undesirable substances that may be introduced as contaminants of natural and malicious origin, and of emerging hazards, in the production chain of farmed salmon,from ova to packed fillet. ... -
Safety in numbers: multiple occurrences of highly similar homologs among Azotobacter vinelandii carbohydrate metabolism proteins probably confer adaptive benefits
(Journal article; Peer reviewed, 2014)Background Gene duplication and horizontal gene transfer are common processes in bacterial and archaeal genomes, and are generally assumed to result in either diversification or loss of the redundant gene copies. However, ... -
Salinity Acclimation Strategies in Nitrifying Bioreactors
(Peer reviewed; Journal article, 2022)Several industries, including aquaculture, produce effluents with high or varying salt concentrations. The treatment of such effluents by the biological nitrification process can be challenging, as the microbes performing ... -
Salinity as a driver for microbial community structure in reactors for nitrification and anammox
(Doctoral theses at NTNU;2016:365, Doctoral thesis, 2016)The removal of nitrogen from wastewater has become an important part of the overall treatment process due to the significant impact of nitrogen compounds (NH4–N, NOx–N) on the environment and the more stringent legislation ... -
Salting of Muscle Foods: Effects of processing conditions and sodium reduction
(Doctoral thesis at NTNU;2014:335, Doctoral thesis, 2014)The present thesis aims at investigating (i) salt distribution in the lean fish- and meat minces, (ii) the effect of different ions on the extractability of salt soluble proteins, and (iii) the possibility to decrease salt ... -
A salty start: Brackish water start-up as a microbial management strategy for nitrifying bioreactors with variable salinity
(Peer reviewed; Journal article, 2020)Nitrifying biofilms developed in brackish water are reported to be more robust to salinity changes than freshwater biofilms. This makes them a promising strategy for water treatment systems with variable salinity, such as ... -
Sammenligning av ekstraksjonsmetoder for vitamin A og vitamin E i grønnkål og crispisalat
(Bachelor thesis, 2024)Oppgavens hovedmål var å etablere en god “in-house” metode for ekstraksjon av vitamin A (i form av β-karoten) og vitamin E (i form av α-tokoferol) i plantemateriale som grønnkål og crispisalat. Hensikten var at metoden ... -
Sammenligning av kjemisk og enzymatisk ekstraksjonsmetoder for melorm Tenebrio molitor og melormskall
(Bachelor thesis, 2023)Bakgrunn - Kitin er et polysakkarid som det finnes rikelig av i naturen. Det kan ekstraheres fra melorm og brukes i næringsmiddelindustrien. Mål - Målet for prosjektet var å ekstrahere kitin fra melorm og melormskall ved ... -
Sammenligning av selektive dyrkningsmedier for påvisning av Aeromonas
(Bachelor thesis, 2019)Metoden for påvisning av Aeromonas utarbeidet av Nordisk Metodikkomité for næringsmidler (NMKL) er ikke optimal. Dyrkningsmediet Stivelses Ampicillin Agar (SAA) som blir benyttet etter denne standarden har vist seg å være ... -
