    • Prenatal BRCA1 epimutations contribute significantly to triple-negative breast cancer development 

      Nikolaienko, Oleksii; Eikesdal, Hans Petter; Berge, Elisabet Ognedal; Gilje, Bjørnar; Lundgren, Steinar; Blix, Egil Støre; Espelid, Helge; Geisler, Jürgen; Geisler, Stephanie; Janssen, Emiel; Yndestad, Synnøve; Minsaas, Laura; Leirvaag, Beryl; Lillestøl, Reidun Kristine; Knappskog, Stian; Lønning, Per Eystein (Peer reviewed; Journal article, 2023)
      Background Normal cell BRCA1 epimutations have been associated with increased risk of triple-negative breast cancer (TNBC). However, the fraction of TNBCs that may have BRCA1 epimutations as their underlying cause is ...
    • Rationale and design of the PRevention of cArdiac Dysfunction during Adjuvant breast cancer therapy (PRADA II) trial: a randomized, placebo-controlled, multicenter trial
