A high-throughput drug combination screen of targeted small molecule inhibitors in cancer cell lines
Flobak, Åsmund; Niederdorfer, Barbara; To, Vu; Thommesen, Liv; Klinkenberg, Geir; Lægreid, Astrid (Journal article; Peer reviewed, 2019)While there is a high interest in drug combinations in cancer therapy, openly accessible datasets for drug combination responses are sparse. Here we present a dataset comprising 171 pairwise combinations of 19 individual ... -
Cytotoxicity of poly(Alkyl cyanoacrylate) nanoparticles
Sulheim, Einar; Iversen, Tore Geir; To, Vu; Klinkenberg, Geir; Sletta, Håvard; Schmid, Ruth; Hatletveit, Anne Rein; Wågbø, Ane Marit; Sundan, Anders; Skotland, Tore; Sandvig, Kirsten; Mørch, Ýrr Asbjørg (Journal article; Peer reviewed, 2017)Although nanotoxicology has become a large research field, assessment of cytotoxicity is often reduced to analysis of one cell line only. Cytotoxicity of nanoparticles is complex and should, preferentially, be evaluated ... -
Global Assessment of Mycobacterium avium subsp. hominissuis Genetic Requirement for Growth and Virulence
Dragset, Marte Singsås; Ioerger, Thomas R.; Loevenich, Maja; Haug, Markus; Sivakumar, Niruja; Marstad, Anne; Cardona, Pere-Joan; Klinkenberg, Geir; Rubin, Eric J.; Steigedal, Magnus; Flo, Trude Helen (Journal article; Peer reviewed, 2019)Nontuberculous mycobacterial infections caused by the opportunistic pathogen Mycobacterium avium subsp. hominissuis (MAH) are currently receiving renewed attention due to increased incidence combined with difficult treatment. ... -
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 ... -
Identification of genes affecting alginate biosynthesis in Pseudomonas fluorescens by screening a transposon insertion library.
Ertesvåg, Helga; Sletta, Håvard; Senneset, Mona; Sun, Yi-Qian; Klinkenberg, Geir; Konradsen, Therese Aursand; Ellingsen, Trond E; Valla, Svein (Journal article; Peer reviewed, 2017)BACKGROUND: Polysaccharides often are necessary components of bacterial biofilms and capsules. Production of these biopolymers constitutes a drain on key components in the central carbon metabolism, but so far little is ... -
Identification of novel cyanoacrylate monomers for use in nanoparticle drug delivery systems prepared by miniemulsion polymerisation – A multistep screening approach
Hyldbakk, Astrid; Mørch, Ýrr Asbjørg; Snipstad, Sofie; Åslund, Andreas; Klinkenberg, Geir; Nakstad, Vu; Wågbø, Ane Marit; Schmid, Ruth Baumberger; Molesworth, Peter Patrick (Peer reviewed; Journal article, 2022)Poly (alkyl cyanoacrylate) (PACA) polymeric nanoparticles (NPs) are promising drug carriers in drug delivery. However, the selection of commercially available alkyl cyanoacrylate (ACA) monomers is limited, because most ... -
Identification of Regulatory Genes and Metabolic Processes Important for Alginate Biosynthesis in Azotobacter vinelandii by Screening of a Transposon Insertion Mutant Library
Mærk, Mali; Jakobsen, Øyvind Mejdell; Sletta, Håvard; Klinkenberg, Geir; Tøndervik, Anne; Ellingsen, Trond Erling; Valla, Svein; Ertesvåg, Helga (Journal article; Peer reviewed, 2020)Azotobacter vinelandii produces the biopolymer alginate, which has a wide range of industrial and pharmaceutical applications. A random transposon insertion mutant library was constructed from A. vinelandii ATCC12518Tc in ... -
Mannuronan C-5 Epimerases Suited for Tailoring of Specific Alginate Structures Obtained by High-Throughput Screening of an Epimerase Mutant Library

The distribution and composition of M/G are important for ... -
Studies of cell release and biomass activity of alginate immobilized lactic acid bacteria
Klinkenberg, Geir (Dr. ingeniøravhandling, 0809-103X; 2002:74, Doctoral thesis, 2002)The scope of the work presented in this thesis has been the study of growth, cell release and metabolite production of gel-entrapped viable lactic acid bacteria. As these fermenation systems are mainly aimed at food ... -
A Study of Models for Prediction of Treatment Response in Cancer
Folkesson, Evelina (Doctoral theses at NTNU;2021:412, Doctoral thesis, 2021)Abstract in Norwegian Kreft kjennetegnes av molekylære forandringer som resulterer i unormal og høy celledeling.
