Combined HER3-EGFR score in triple-negative breast cancer provides prognostic and predictive significance superior to individual biomarkers
Ogden, Angela; Bhattarai, Shristi; Sahoo, Bikram; Mongan, Nigel P.; Alsaleem, Mansour; Green, Andrew R.; Aleskandarany, Mohammed; Ellis, Ian O.; Pattni, Sonal; Li, Xiaoxian Bill; Moreno, Carlos S.; Krishnamurti, Uma; Janssen, Emiel; Jonsdottir, Kristin; Rakha, Emad; Rida, Padmashree; Aneja, Ritu (Peer reviewed; Journal article, 2020)Epidermal growth factor receptor (EGFR) and human epidermal growth factor receptor 3 (HER3) have been investigated as triple-negative breast cancer (TNBC) biomarkers. Reduced EGFR levels can be compensated by increases in ... -
Digital Image Analysis of Ki-67 Stained Tissue Microarrays and Recurrence in Tamoxifen-Treated Breast Cancer Patients
Egeland, Nina Gran; Jonsdottir, Kristin; Lauridsen, Kristina Lystlund; Skaland, Ivar; Hjorth, Cathrine F.; Gudlaugsson, Einar; Hamilton-Dutoit, Stephen Jacques; Lash, Timothy L.; Cronin-Fenton, Deidre; Janssen, Emiel (Peer reviewed; Journal article, 2020-07)Purpose: The proliferation marker Ki-67 has been used as a prognostic marker to separate low- and high-risk breast cancer subtypes and guide treatment decisions for adjuvant chemotherapy. The association of Ki-67 with ... -
Discovery and Validation of Biomarkers in Breast Cancer
Egeland, Nina Gran (PhD thesis UiS;546, Doctoral thesis, 2020-09)Worldwide, breast cancer is the most common malignancy among women, and although treatment and prognosis have improved substantially over the last decades, for some patients the risk of recurrence remains for several years ... -
Fatigue in primary Sjögren's syndrome: A proteomic pilot study of cerebrospinal fluid
Larssen, Eivind; Brede, Cato; Hjelle, Anne; Tjensvoll, Anne Bolette; Norheim, Katrine Brække; Bårdsen, Kjetil; Jonsdottir, Kristin; Ruoff, Peter; Omdal, Roald; Nilsen, Mari Mæland (Peer reviewed; Journal article, 2019-05)Objectives: Fatigue is a frequent and often disabling phenomenon that occurs in patients with chronic inflammatory and immunological diseases, and the underlying biological mechanisms are largely unknown. Because fatigue ... -
Heat Shock Proteinα and Fatigue in Breast Cancer - A Cross Sectional Study
Andersen, Torill (Master thesis, 2021)Breast cancer is the most frequent malignancy among women and is often associated with fatigue during treatment. Fatigue may be considered as a sickness behavior syndrome, which is induced by activation of the innate immune ... -
Interleukin-1-related activity and hypocretin-1 in cerebrospinal fluid contribute to fatigue in primary Sjögren's syndrome
Bårdsen, Kjetil; Brede, Cato; Kvivik, Ingeborg; Kvaløy, Jan Terje; Jonsdottir, Kristin; Tjensvoll, Anne Bolette; Ruoff, Peter; Omdal, Roald (Peer reviewed; Journal article, 2019)Background Fatigue is a common and sometimes debilitating phenomenon in primary Sjögren’s syndrome (pSS) and other chronic inflammatory diseases. We aimed to investigate how IL-1 β-related molecules and the neuropeptide ... -
Metabolic consequences of perioperative oral carbohydrates in breast cancer patients - an explorative study

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 ... -
The role of microRNAs as predictors of response to tamoxifen treatment in breast cancer patients
Egeland, Nina; Lunde, Siri; Jonsdottir, Kristin; Lende, Tone Hoel; Cronin-Fenton, Deirdre P.; Gilje, Bjørnar; Janssen, Emilius Adrianus Maria; Søiland, Håvard (Journal article; Peer reviewed, 2015-10)Endocrine therapy is a key treatment strategy to control or eradicate hormone-responsive breast cancer. However, resistance to endocrine therapy leads to breast cancer relapse. The recent extension of adjuvant tamoxifen ... -
