      Previous studies have shown that woman’s risk of breast cancer in later life is associated with her infants birth weights. The objective of this study was to determine if this association is independent of breast cancer risk factors, mother’s own birth weight and to evaluate association between infants birth weight and hormonal environment during pregnancy. Independent association would have ...
    • Bisphenol A replacement chemicals, BPF and BPS, induce protumorigenic changes in human mammary gland organoid morphology and proteome 

      Winkler, Juliane; Liu, Pengyuan; Phong, Kiet; Hinrichs, Johanna H.; Ataii, Nassim; Williams, Katherine; Hadler-Olsen, Elin Synnøve; Samson, Susan; Gartner, Zev J.; Fisher, Susan; Werb, Zena (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-03-09)
      Environmental chemicals such as bisphenol A (BPA) are thought to contribute to carcinogenesis through their endocrine-disrupting properties. Due to accumulating evidence about negative human health effects, BPA is being phased out, but in parallel, exposures to replacement chemicals such as bisphenol S (BPS) and bisphenol F (BPF) are increasing. Little is known about their biologic effects, but ...
    • BKV Agnoprotein Interacts with alpha-Soluble N-Ethylmaleimide-Sensitive Fusion Attachment Protein, and Negatively Influences Transport of VSVG-EGFP 

      Johannessen, Mona; Walquist, Mari; Gerits, Nancy; Dragset, Marte Singsås; Spang, Anne; Moens, Ugo (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      The human polyomavirus BK (BKV) infects humans worldwide and establishes a persistent infection in the kidney. The BK virus genome encodes three regulatory proteins, large and small tumor-antigen and the agnoprotein, as well as the capsid proteins VP1 to VP3. Agnoprotein is conserved among BKV, JC virus (JCV) and SV40, and agnoprotein-deficient mutants reveal reduced viral propagation. Studies with ...

      Background: Some epidemiological, clinical, and laboratory studies suggest that underweight and obesity impact fertility. Methods: This is cross-sectional study of 33,159 North American Adventist women, who were nulliparous at age 20 years and who, as a group, have a healthy lifestyle. Logistic regression analysis was used to assess how body mass index (BMI, kg/m2) at age 20 was related to never ...
    • Bone Marrow Adipocytes: The Enigmatic Components of the Hematopoietic Stem Cell Niche 

      Cuminetti, Vincent; Arranz, Lorena (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-05-18)
      Bone marrow adipocytes (BMA) exert pleiotropic roles beyond mere lipid storage and filling of bone marrow (BM) empty spaces, and we are only now beginning to understand their regulatory traits and versatility. BMA arise from the differentiation of BM mesenchymal stromal cells, but they seem to be a heterogeneous population with distinct metabolisms, lipid compositions, secretory properties and ...
    • Bone Turnover and Metabolism in Patients with Early Multiple Sclerosis and Prevalent Bone Mass Deficit: A Population-Based Case-Control Study 

      Moen, Stine Marit; Celius, Elisabeth Gulowsen; Sandvik, Leiv; Brustad, Magritt; Nordsletten, Lars; Eriksen, Erik Fink; Holmøy, Trygve (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Low bone mass is prevalent in ambulatory multiple sclerosis (MS) patients even shortly after clinical onset. The mechanism is not known, but could involve shared etiological risk factors between MS and low bone mass such as hypovitaminosis D operating before disease onset, or increased bone loss after disease onset. The aim of this study was to explore the mechanism of the low bone mass in early-stage ...
