Community assessment to advance computational prediction of cancer drug combinations in a pharmacogenomic screen
Kuiper, Martin; Lægreid, Astrid; Flobak, Åsmund; Thommesen, Liv; Team, Dream (Journal article; Peer reviewed, 2019)The effectiveness of most cancer targeted therapies is short-lived.

High-throughput screening reveals higher synergistic effect of MEK inhibitor combinations in colon cancer spheroids
Folkesson, Evelina; Niederdorfer, Barbara; To, Vu; Thommesen, Liv; Klinkenberg, Geir; Lægreid, Astrid; Flobak, Åsmund (Peer reviewed; Journal article, 2020)Drug combinations have been proposed to combat drug resistance, but putative treatments are challenged by low bench-to-bed translational efficiency. To explore the effect of cell culture format and readout methods on ... -
Holdbarhetsstudie - kjølig oppbevaring av prøver til analyse av PT-INR
Matberg, Karianne; Martinsen, Stine Karoline (Bachelor thesis, 2020)I dette forsøket ble det utført en holdbarhetsstudie hvor det ble undersøkt om blodprøver oppbevart kjølig (5°C) kunne gi et signifikant endret analysesvar i forhold tilsvarende prøve oppbevart i romtemperatur. Dette ble ... -
Identification of MicroRNA Expression in Gastrin Stimulated Adenocarcinoma Cells
Bergly, Laila H. (Master thesis, 2011)The Gastrin System Biology group studies the molecular responses to gastrin using cell line model systems. Recently microRNAs (miRNAs) have been acknowledged as essential participants in the regulation of gene expression, ... -
In vitro validation of anticancer drug combinations on colon cancer cell lines SW620 and HCT116
Greina, Marianne (Master thesis, 2018)Combinatory drug treatment, e.g. targeting different proteins in specific signaling pathways tailored to an individual’s tumor, is expected to overcome problems related to individual variation in drug efficacy, resistance ... -
