AID expression in B-cell lymphomas causes accumulation of genomic uracil and a distinct AID mutational signature
Pettersen, Henrik Sahlin; Galashevskaya, Anastasia; Doseth, Berit; Sousa, Mirta; Sarno, Antonio; Visnes, Torkild; Aas, Per Arne; Liabakk, Nina-Beate; Slupphaug, Geir; Sætrom, Pål; Kavli, Bodil Merete; Krokan, Hans Einar (Journal article; Peer reviewed, 2014)tThe most common mutations in cancer are C to T transitions, but their origin has remained elusive.Recently, mutational signatures of APOBEC-family cytosine deaminases were identified in many com-mon cancers, suggesting ... -
Cytotoxicity and repair of uracil and 5-fluorouracil in DNA
Pettersen, Henrik Sahlin (Doktoravhandlinger ved NTNU, 1503-8181; 2011:95, Doctoral thesis, 2011)Cytotoksisitet og reparasjon av uracil og 5-fluorouracil i DNA Vårt arvemateriale (gener) er organisert i 23 kromosompar, som det finnes fullstendige kopier av i storparten av våre celler. Hvert kromosom består av en lang ... -
Deep learning-based image analysis reveals significant differences in the number and distribution of mucosal CD3 and γδ T cells between Crohn's disease and ulcerative colitis
Røyset, Elin Synnøve; Pettersen, Henrik Sahlin; Xu, Weili; Larbi, Anis; Sandvik, Arne Kristian; Steigen, Sonja Eriksson; Catalan-Serra, Ignacio; Bakke, Ingunn (Peer reviewed; Journal article, 2022)Colon mucosae of ulcerative colitis (UC) and Crohn's disease (CD) display differences in the number and distribution of immune cells that are difficult to assess by eye. Deep learning-based analysis on whole slide images ... -
Established and novel methods and biomarkers in breast cancer
Skjervold, Anette Hansen (Doctoral theses at NTNU;2024:80, Doctoral thesis, 2024)The present thesis is based on three published papers. The work arises from three cohorts of women from Trøndelag county in Norway. These were women born between 1886 and 1977, that were diagnosed with breast cancer (BC). ... -
UNG-initiated base excision repair is the major repair route for 5-fluorouracil in DNA, but 5-fluorouracil cytotoxicity depends mainly on RNA incorporation
Pettersen, Henrik Sahlin; Visnes, Torkild; Vågbø, Cathrine Broberg; Svaasand, Eva K; Doseth, Berit; Slupphaug, Geir; Kavli, Bodil Merete; Krokan, Hans Einar (Journal article; Peer reviewed, 2011)Cytotoxicity of 5-fluorouracil (FU) and 5-fluoro-2′-deoxyuridine (FdUrd) due to DNA fragmentation during DNA repair has been proposed as an alternative to effects from thymidylate synthase (TS) inhibition or RNA incorporation. ...
