      Background: During atherogenesis, cholesterol precipitates into cholesterol crystals (CC) in the vessel wall, which trigger plaque inflammation by activating the NACHT, LRR and PYD domains-containing protein 3 (NLRP3) ...
    • Complex alternative splicing of human Endonuclease V mRNA, but evidence for only a single protein isoform 

      Berges, Natalia; Nawaz, Meh Sameen; Dahl, Tuva Børresdatter; Hagen, Lars; Bjørås, Magnar; Lærdahl, Jon Kristen; Alseth, Ingrun (Journal article; Peer reviewed, 2019)
      Endonuclease V (ENDOV) is a ribonuclease with affinity for inosine which is the deamination product of adenosine. The genomes of most organisms, including human, encode ENDOV homologs, yet knowledge about in vivo functions ...
    • Deletion of Endonuclease V suppresses chemically induced hepatocellular carcinoma 

      Kong, Xiang Yi; Vik, Erik Sebastian; Nawaz, Meh Sameen; Berges, Natalia; Dahl, Tuva Børresdatter; Vågbø, Cathrine; Suganthan, Rajikala; Segers, Filip; Holm, Sverre; Quiles-Jimenez, Ana; Gregersen, Ida; Fladeby, Cathrine; Aukrust, Pål; Bjørås, Magnar; Klungland, Arne; Halvorsen, Bente; Alseth, Ingrun (Peer reviewed; Journal article, 2020)
      Endonuclease V (EndoV) is a conserved inosine-specific ribonuclease with unknown biological function. Here, we present the first mouse model lacking EndoV, which is viable without visible abnormalities. We show that ...
    • Gut microbiota-dependent trimethylamine N-oxide associates with inflammation in common variable immunodeficiency 

      Macpherson, Magnhild Eide; Hov, Johannes Espolin Roksund; Ueland, Thor; Dahl, Tuva Børresdatter; Kummen, Martin; Otterdal, Kari; Holm, Kristian; Berge, Rolf Kristian; Mollnes, Tom Eirik; Trøseid, Marius; Halvorsen, Bente; Aukrust, Pål; Fevang, Børre; Jørgensen, Silje Fjellgård (Peer reviewed; Journal article, 2020)
      A substantial proportion of patients with common variable immunodeficiency (CVID) have inflammatory and autoimmune complications of unknown etiology. We have previously shown that systemic inflammation in CVID correlates ...
    • Increased levels of legumain in plasma and plaques from patients with carotid atherosclerosis 

      Lunde, Ngoc Nguyen Dieu; Holm, Sverre; Dahl, Tuva Børresdatter; Inass, Elyouncha; Sporsheim, Bjørnar; Gregersen, Ida; Abbas, Azhar; Skjelland, Mona; Espevik, Terje; Solberg, Rigmor; Johansen, Harald Thidemann; Halvorsen, Bente (Journal article; Peer reviewed, 2017)
      Background and aims The cysteine protease legumain has been shown to be up-regulated in unstable atherosclerotic plaques. This study aims to further elucidate legumain in atherosclerosis, by examining legumain in plasma ...
    • Increased serum levels of LIGHT/TNFSF14 in nonalcoholic fatty liver disease: Possible role in hepatic inflammation 

      Otterdal, Kari; Haukeland, John Willy; Yndestad, Arne; Dahl, Tuva Børresdatter; Holm, Sverre; Segers, Filip; Gladhaug, Ivar Prydz; Zbigniew, Konopski; Damås, Jan Kristian; Halvorsen, Bente; Aukrust, Pål (Journal article; Peer reviewed, 2015)
      Objectives: The tumor necrosis factor superfamily member 14, LIGHT (homologous to lymphotoxin, exhibits inducible expression, and competes with HSV glycoprotein D for herpes virus entry mediator (HVEM), a receptor expressed ...
    • Interleukin 27 is increased in carotid atherosclerosis and promotes NLRP3 inflammasome activation. 

      Gregersen, Ida; Sandanger, Øystein; Askevold, Erik Tandberg; Sagen, Ellen Lund; Yang, Kuan; Holm, Sverre; Pedersen, Turid Margrethe; Skjelland, Mona; Krohg-Sørensen, Kirsten; Hansen, Trond Vidar; Dahl, Tuva Børresdatter; Otterdal, Kari; Espevik, Terje; Aukrust, Pål; Yndestad, Arne; Halvorsen, Bente (Journal article; Peer reviewed, 2017)
      Aim Interleukin-27 (IL-27) is involved in different inflammatory diseases; however, its role in atherosclerosis is unclear. In this study we investigated the expression of IL-27 and its receptor in patients with carotid ...
    • Neil3-dependent base excision repair regulates lipid metabolism and prevents atherosclerosis in Apoe-deficient mice
