    Mesenchymal stem cells are a promising source for externally grown tissue replacements and patient-specific immunomodulatory treatments. This promise has not yet been fulfilled in part due to production scaling issues and the need to maintain the correct ...
  • Wang, Qiong (University of Iceland, School of Health Sciences, Faculty of Medicine, 2022-05-24)
    Breast cancer is the leading cause of cancer deaths among women in Iceland and worldwide. Epithelial-mesenchymal transition (EMT) is a cellular developmental process where epithelial cells assume mesenchymal-like phenotypes through degradation of the ...

    The increasing availability of metabolomics data necessitates novel methods for deeper data analysis and interpretation. We present a flux balance analysis method that allows for the computation of dynamic intracellular metabolic changes at the cellular ...
  • Hrolfsdottir, Laufey (University of Iceland, School of Health Sciences, Faculty of Food Science and Nutrition, 2018-01)
    Aim: The aim of this Ph.D. thesis is to enhance understanding of the relation between maternal diet, gestational weight gain (GWG), and offspring’s cardio-metabolic factors. Moreover, the objective is to identify dietary predictors for excessive GWG. ...

    Twenty-eight sponge specimens were collected at a shallow water hydrothermal vent site north of Iceland. Extracts were prepared and tested in vitro for cytotoxic activity, and eight of them were shown to be cytotoxic. A mass spectrometry (MS)-based ...
  • Halldorsson, Skarphedinn; Rohatgi, Neha; Magnúsdóttir, Manuela; Choudhary, Kumari Sonal; Gudjonsson, Thorarinn; Knutsen, Erik; Barkovskaya, Anna; Hilmarsdóttir, Bylgja; Perander, Maria; Mælandsmo, Gunhild M.; Guðmundsson, Steinn; Rolfsson, Óttar (Elsevier BV, 2017-06)
    Epithelial to mesenchymal transition (EMT) has implications in tumor progression and metastasis. Metabolic alterations have been described in cancer development but studies focused on the metabolic re-wiring that takes place during EMT are still limited. ...
  • Karvelsson, Sigurður Trausti (University of Iceland, School of Health Sciences, Faculty of Medicine, 2022-02-25)
    Breast cancer is a heterogenous disease in which the mechanism for signalling, gene expression, metabolism and growth in breast tissue is deranged. Breast cancer is responsible for the death of over 600,000 people worldwide on a yearly basis. By ...
