    • CCND1 amplification in breast cancer -associations with proliferation, histopathological grade, molecular subtype and prognosis 

      Valla, Marit; Klæstad, Elise; Ytterhus, Borgny; Bofin, Anna M. (Peer reviewed; Journal article, 2022)
      CCND1 is located on 11q13. Increased CCND1 copy number (CN) in breast cancer (BC) is associated with high histopathological grade, high proliferation, and Luminal B subtype. In this study of CCND1 in primary BCs and ...

    • Characterization of FGD5 expression in primary breast cancers and lymph node metastases 

      Valla, Marit; Mjønes, Patricia; Engstrøm, Monica J; Ytterhus, Borgny; Bordin, Diana Lilian; van Loon, Barbara; Akslen, Lars A.; Vatten, Lars Johan; Opdahl, Signe; Bofin, Anna M. (Journal article; Peer reviewed, 2018)
      Faciogenital dysplasia 5 (FGD5) amplification drives tumor cell proliferation, and is present in 9.5% of breast cancers. We describe FGD5 expression, assess associations between FGD5 amplification and FGD5 expression, and ...

    • DTX3 copy number increase in breast cancer: a study of associations to molecular subtype, proliferation and prognosis 

      Valla, Marit; Opdahl, Signe; Ytterhus, Borgny; Bofin, Anna M. (Journal article; Peer reviewed, 2021)
      Purpose The degree of cell proliferation is important for subclassifcation of breast cancers into prognostic and therapeutic groups. DTX3 has been identifed as a driver of proliferation in luminal breast cancer. In this ...

    • Expression and clinical value of EGFR in human meningiomas 

      Arnli, Magnus B.; Backer-Grøndahl, Thomas; Ytterhus, Borgny; Granli, Unn S.; Lydersen, Stian; Gulati, Sasha; Torp, Sverre Helge (Journal article; Peer reviewed, 2017)
      Background Meningiomas are common intracranial tumors in humans that frequently recur despite having a predominantly benign nature. Even though these tumors have been shown to commonly express EGFR/c-erbB1 (epidermal ...

    • FGD5 amplification in breast cancer patients is associated with tumor proliferation and a poorer prognosis 

      Valla, Marit; Engstrøm, Monica J; Ytterhus, Borgny; Hansen, Åse Kristin Skain; Akslen, Lars A.; Vatten, Lars Johan; Opdahl, Signe; Bofin, Anna M. (Journal article; Peer reviewed, 2017)
      Purpose Proliferation is a hallmark of cancer. Using a combined genomic approach, FGD5 amplification has been identified as a driver of proliferation in Luminal breast cancer. We aimed to describe FGD5 copy number change ...

    • Molecular Subtypes of Breast Cancer: Long-term Incidence Trends and Prognostic Differences 

      Valla, Marit; Vatten, Lars Johan; Engstrøm, Monica J; Haugen, Olav Anton; Akslen, Lars A.; Bjørngaard, Johan Håkon; Hagen, Anne Irene; Ytterhus, Borgny; Bofin, Anna M.; Opdahl, Signe (Journal article; Peer reviewed, 2016)
      Background: Secular trends in incidence and prognosis of molecular breast cancer subtypes are poorly described. We studied long-term trends in a population of Norwegian women born 1886–1977. Methods: A total of 52,949 ...

    • MRPS23 amplification and gene expression in breast cancer; association with proliferation and the non-basal subtypes 

      Klæstad, Elise; Opdahl, Signe; Engstrøm, Monica J; Ytterhus, Borgny; Wik, Elisabeth; Bofin, Anna Mary; Valla, Marit (Peer reviewed; Journal article, 2020)
      Purpose MRPS23 is recognized as a driver of proliferation in luminal breast cancer. The aims of the present study were to describe MRPS23 copy number change in breast cancer, and to assess associations between MRPS23 ...

    • PAK1 copy number in breast cancer—Associations with proliferation and molecular subtypes 

      Skjervold, Anette Hansen; Valla, Marit; Ytterhus, Borgny; Bofin, Anna M. (Peer reviewed; Journal article, 2023)
      Introduction P21-activated kinase 1 (PAK1) is known to be overexpressed in several human tumour types, including breast cancer (BC). It is located on chromosome 11 (11q13.5-q14.1) and plays a significant role in proliferation ...

    • PD-L1 Protein Expression in Breast Cancer 

      Saastad, Sigurd August; Skjervold, Anette Hansen; Ytterhus, Borgny; Engstrøm, Monica Jernberg; Bofin, Anna Mary (Master thesis, 2023)
      Tumorcellers evne til å unngå destruksjon av immunforsvaret, har blitt foreslått som et av de nye kjennetegnene til kreft av Hanahan og Weinberg i 2011. Både T-celler, B-celler, makrofager, polymorfonukleære celler, naturlige ...

    • S100A8 gene copy number and protein expression in breast cancer: associations with proliferation, histopathological grade and molecular subtypes 

      Børkja, Mathieu; Giambelluca, Miriam Soledad; Ytterhus, Borgny; Prestvik, Wenche Slettahjell; Bjørkøy, Geir; Bofin, Anna M. (Peer reviewed; Journal article, 2023)
      Background and aims Amplification of S100A8 occurs in 10–30% of all breast cancers and has been linked to poorer prognosis. Similarly, the protein S100A8 is overexpressed in a roughly comparable proportion of breast cancers ...

    • TOP2A gene copy number change in breast cancer 

      Engstrøm, Monica J; Ytterhus, Borgny; Vatten, Lars Johan; Opdahl, Signe; Bofin, Anna M. (Peer reviewed; Journal article, 2014)
