    • Absence of the proteoglycan decorin reduces glucose tolerance in overfed male mice 

      Svärd, Jessica; Røst, Therese Halvorsen; Sommervoll, Camilla Elise Nergård; Haugen, Christine; Gudbrandsen, Oddrun Anita; Christensen, Anne Elisabeth; Rødahl, Eyvind; Fernø, Johan; Dankel, Simon N; Sagen, Jørn V.; Mellgren, Gunnar (Peer reviewed; Journal article, 2019)
      Studies have implicated the extracellular matrix (ECM) of adipose tissue in insulin resistance. The proteoglycan decorin, a component of ECM, has been associated with glucose tolerance, but possible causal effects on ...

    • COL6A3 expression in adipose tissue cells is associated with levels of the homeobox transcription factor PRRX1

      Fibrillar collagen COL6α3 in adipose tissue has been associated with obesity, inflammation, insulin resistance and cancer. We here aimed to identify novel transcriptional regulators of COL6A3 expression. Based on a ...

    • Genome-wide association study reveals dynamic role of genetic variation in infant and early childhood growth 

      Helgeland, Øyvind; Vaudel, Marc; Juliusson, Petur Benedikt; Holmen, Oddgeir Lingaas; Juodakis, Julius; Bacelis, Jonas; Jacobsson, Bo; Lindekleiv, Haakon; Hveem, Kristian; Lie, Rolv T.; Knudsen, Gun Peggy Strømstad; Stoltenberg, Camilla; Magnus, Per; Sagen, Jørn V.; Molven, Anders; Johansson, Stefan; Njølstad, Pål Rasmus (Peer reviewed; Journal article, 2019-10-01)
      Infant and childhood growth are dynamic processes with large changes in BMI during development. By performing genome-wide association studies of BMI at 12 time points from birth to eight years (9286 children, 74,105 ...

    • Hormone references for ultrasound breast staging and endocrine profiling to detect female onset of puberty 

      Madsen, Andre; Bruserud, Ingvild Særvold; Bertelsen, Bjørn-Erik; Roelants, Mathieu; Oehme, Ninnie; Viste, Kristin; Bjerknes, Robert; Almås, Bjørg; Rosendahl, Karen; Mellgren, Gunnar; Sagen, Jørn V.; Juliusson, Petur Benedikt (Journal article; Peer reviewed, 2020)
      Context Application of ultrasound (US) to evaluate attainment and morphology of glandular tissue provides a new rationale for evaluating onset and progression of female puberty, but currently no hormone references complement ...

    • Metformin inhibits hepatocellular glucose, lipid and cholesterol biosynthetic pathways by transcriptionally suppressing steroid receptor coactivator 2 (SRC-2) 

      Madsen, Andre; Bozickovic, Olivera; Bjune, Jan Inge; Mellgren, Gunnar; Sagen, Jørn V. (Peer reviewed; Journal article, 2015-11-09)
      The ability of the anti-diabetic drug metformin to inhibit anabolic processes including gluconeogenesis and lipogenesis is partly attributable to activation of the AMP-activated protein kinase (AMPK) pathway. The p160 ...

    • Reference curves for pediatric endocrinology: leveraging biomarker z-scores for clinical classifications 

      Madsen, Andre; Almås, Bjørg; Bruserud, Ingvild Særvold; Oehme, Ninnie Helen Bakken; Nielsen, Christopher Sivert; Roelants, Mathieu; Hundhausen, Thomas Eckhard; Ljubicic, Marie Lindhardt; Bjerknes, Robert; Mellgren, Gunnar; Sagen, Jørn V.; Juliusson, Pétur Benedikt; Viste, Kristin (Journal article; Peer reviewed, 2022)
      Context Hormone reference intervals in pediatric endocrinology are traditionally partitioned by age and lack the framework for benchmarking individual blood test results as normalized z-scores and plotting sequential ...
