      Increasing evidence suggests that oxidative DNA damage accumulates in atherosclerosis. Recently, we showed that a genetic variant in the human DNA repair enzyme NEIL3 was associated with increased risk of myocardial ...
    • Neuromodulatory effect of NLRP3 and ASC in neonatal hypoxic ischemic encephalopathy 

      Ystgaard, Martin Bogale; Scheffler, Katja; Suganthan, Rajikala; Bjørås, Magnar; Ranheim, Trine; Sagen, Ellen Lund; Halvorsen, Bente; Saugstad, Ola Didrik; Yndestad, Arne (Journal article; Peer reviewed, 2019)
      Background: Following birth asphyxia there is a robust inflammatory response. NLRP3 is a receptor of the innate immune system. Upon activation, NLRP3 forms an inflammasome together with ASC and procaspase-1 to mediate ...
    • No cancer predisposition or increased spontaneous mutation frequencies in NEIL DNA glycosylases-deficient mice 

      Rolseth, Veslemøy; Luna, Luisa; Olsen, Ann-Karin; Suganthan, Rajikala; Scheffler, Katja; Neurauter, Christine Gran; Esbensen, Qin Ying; Kusnierczyk, Anna; Hildrestrand, Gunn Annette; Graupner, Anne; Andersen, Jill Mari; Slupphaug, Geir; Klungland, Arne; Nilsen, Hilde; Bjørås, Magnar (Journal article; Peer reviewed, 2017)
      Base excision repair (BER) is a major pathway for removal of DNA base lesions and maintenance of genomic stability, which is essential in cancer prevention. DNA glycosylases recognize and remove specific lesions in the ...
    • OXR1A, a Coactivator of PRMT5 Regulating Histone Arginine Methylation 

      Yang, Mingyi; Lin, Xiaolin; Segers, Filip; Suganthan, Rajikala; Hildrestrand, Gunn Annette; Rinholm, Johanne Egge; Aas, Per Arne; Sousa, Mirta; Holm, Sverre; Bolstad, Nils; Warren, David; Berge, Rolf Kristian; Johansen, Rune Forstrøm; Yndestad, Arne; Kristiansen, Elise; Klungland, Arne; Gomez, Luisa Fernanda Luna; Eide, Lars; Halvorsen, Bente; Aukrust, Pål; Bjørås, Magnar (Peer reviewed; Journal article, 2020)
      Oxidation resistance gene 1 (OXR1) protects cells against oxidative stress. We find that male mice with brain-specific isoform A knockout (Oxr1A−/−) develop fatty liver. RNA sequencing of male Oxr1A−/− liver indicates ...
