MiR-18a and miR-18b are expressed in the stroma of oestrogen receptor alpha negative breast cancers
Egeland, Nina Gran; Jonsdottir, Kristin; Aure, Miriam Ragle; Sahlberg, Kristine Kleivi; Kristensen, Vessela N.; Cronin-Fenton, Deirdre; Skaland, Ivar; Gudlaugsson, Einar; Baak, Jan P.A.; Janssen, Emiel (Peer reviewed; Journal article, 2020-05)Background Previously, we have shown that miR-18a and miR-18b gene expression strongly correlates with high proliferation, oestrogen receptor -negativity (ER−), cytokeratin 5/6 positivity and basal-like features of breast ... -
miRNA normalization enables joint analysis of several datasets to increase sensitivity and to reveal novel miRNAs differentially expressed in breast cancer
Ben-Elazar, Shay; Aure, Miriam Ragle; Jonsdottir, Kristin; Leivonen, Suvi-Katri; Kristensen, Vessela N.; Janssen, Emiel; Sahlberg, Kristine Kleivi; Lingjærde, Ole Christian; Yakhini, Zohar (Peer reviewed; Journal article, 2021-02)Different miRNA profiling protocols and technologies introduce differences in the resulting quantitative expression profiles. These include differences in the presence (and measurability) of certain miRNAs. We present and ... -
Serum concentrations of active tamoxifen metabolites predict long-term survival in adjuvantly treated breast cancer patients
Helland, Thomas; Henne, Nina; Bifulco, Ersilia; Naume, Bjørn; Borgen, Elin; Kristensen, Vessela N.; Kvaløy, Jan Terje; Lash, Timothy L; Grenaker, Grethe Irene; van Schaik, RHN; Janssen, Emiel; Hustad, Steinar; Lien, Ernst Asbjørn; Mellgren, Gunnar; Søiland, Håvard (Journal article; Peer reviewed, 2017)Background Controversies exist as to whether the genetic polymorphisms of the enzymes responsible for the metabolism of tamoxifen can predict breast cancer outcome in patients using adjuvant tamoxifen. Direct measurement ...
