    • Biosynthesis of Promatrix Metalloproteinase-9/Chondroitin Sulphate Proteoglycan Heteromer Involves a Rottlerin-Sensitive Pathway 

      Malla, Nabin; Berg, Eli; Moens, Ugo; Uhlin-Hansen, Lars; Winberg, Jan-Olof (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Background: Previously we have shown that a fraction of the matrix metalloproteinase-9 (MMP-9) synthesized by the macrophage cell line THP-1 was bound to a chondroitin sulphate proteoglycan (CSPG) core protein as a reduction sensitive heteromer. Several biochemical properties of the enzyme were changed when it was bound to the CSPG. <br>Methodology/Principal Findings: By use of affinity chromatography, ...

    • Cleavage of the urokinase receptor (uPAR) on oral cancer cells: Regulation by transforming growth factor - beta1 (TGF-beta1) and potential effects on migration and invasion 

      Magnussen, Synnøve; Hadler-Olsen, Elin Synnøve; Costea, Daniela Elena; Berg, Eli; Cavalcanti Jacobsen, Cristiane de Albuquerque; Mortensen, Bente; Salo, Tuula; Martinez, Inigo Zubiavrre; Winberg, Jan-Olof; Uhlin-Hansen, Lars; Svineng, Gunbjørg (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-05-19)
      Background: Urokinase plasminogen activator (uPA) receptor (uPAR) is up-regulated at the invasive tumour front of human oral squamous cell carcinoma (OSCC), indicating a role for uPAR in tumour progression. We previously observed elevated expression of uPAR at the tumour-stroma interface in a mouse model for OSCC, which was associated with increased proteolytic activity. The tumour microenvironment ...

    • Det skapende mellomrommet i møtet mellom pasient og lege 

      Berg, Eli (Doctoral thesis; Doktorgradsavhandling, 2004)

    • Molecular Interactions Stabilizing the Promatrix Metalloprotease-9·Serglycin Heteromer 

      Dawadi, Rangita; Malla, Nabin; Hegge, Beate; Wushur, Imin; Berg, Eli; Svineng, Gunbjørg; Sylte, Ingebrigt; Winberg, Jan-Olof (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-12)
      Previous studies have shown that THP-1 cells produced an SDS-stable and reduction-sensitive complex between proMMP-9 and a chondroitin sulfate proteoglycan (CSPG) core protein. The complex could be reconstituted in vitro using purified serglycin (SG) and proMMP-9 and contained no inter-disulfide bridges. It was suggested that the complex involved both the FnII module and HPX domain of proMMP-9. The ...

    • Proteases in plasma and kidney of db /db mice as markers of diabetes-induced nephropathy 

      Hadler-Olsen, Elin Synnøve; Winberg, Jan-Olof; Reinholt, Finn P.; Larsen, Terje; Uhlin-Hansen, Lars; Jenssen, Trond Geir; Berg, Eli; Kolset, Svein Olav (Journal article; Tidsskriftartikkel; Peer reviewed, 2011)
      Db/db mice are overweight, dyslipidemic and develop diabetic complications, relevant for similar complications in human type 2 diabetes. We have used db/db and db/+ control mice to investigate alterations in proteinase expression and activity in circulation and kidneys by SDS-PAGE zymography, electron microscopy, immunohistochemistry, Western blotting, and in situ zymography. Plasma from db/db mice ...

    • The selectivity of galardin and an azasugar-based hydroxamate compound for human Matrix metalloproteases and bacterial metalloproteases 

      Sylte, Ingebrigt; Dawadi, Rangita; Malla, Nabin; von Hofsten, Susannah; Nguyen, Tra-Mi; Solli, Ann Iren; Berg, Eli; Adekoya, Olayiwola A.; Svineng, Gunbjørg; Winberg, Jan-Olof (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-08-03)
      Inhibitors targeting bacterial enzymes should not interfere with enzymes of the host, and knowledge about structural determinants for selectivity is important for designing inhibitors with a therapeutic potential. We have determined the binding strengths of two hydroxamate compounds, galardin and compound 1b for the bacterial zinc metalloproteases, thermolysin, pseudolysin and auerolysin, known to ...
