    • Crystallized but not soluble uric acid elicits pro-inflammatory response in short-term whole blood cultures from healthy men 

      Brovold, Henrik; Lund, Trine; Svistounov, Dmitri; Solbu, Marit Dahl; Jenssen, Trond Geir; Ytrehus, Kirsti; Zykova, Svetlana (Journal article; Tidsskriftartikkel; Peer reviewed, 2019-07-19)
      Several epidemiological studies have pointed at serum uric acid (SUA) as an independent risk factor for mortality, diabetes, hypertension, cardiovascular and kidney disease; however, no clear pathogenic pathway is established. Uric acid (UA) crystals show pro-inflammatory properties and can thus create or contribute to the state of chronic low-grade inflammation, a widely accepted pathogenic mechanism ...

    • Development of quantitative assay for simultaneous measurement of purine metabolites and creatinine in biobanked urine by liquid chromatography-tandem mass spectrometry 

      Svistounov, Dmitri; Solbu, Marit Dahl; Jenssen, Trond Geir; Mathisen, Ulla Dorte; Hansen, Terkel; Elgstøen, Katja Benedikte Prestø; Zykova, Svetlana (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-01-20)
      Purine metabolism is essential for all known living creatures, including humans in whom elevated serum concentration of purine break-down product uric acid (UA) is probably an independent risk factor for mortality, type 2 diabetes and cardiovascular events. An automated multiplex assay that measures several purine metabolites could therefore prove useful in many areas of medical, veterinary and ...

    • Hepatic disposal of advanced glycation end products during maturation and aging 

      Svistounov, Dmitri; Oteiza, Ana; Zykova, Svetlana; Sørensen, Karen Kristine; McCourt, Peter Anthony; McLachlan, Andrew J; Mccuskey, Robert Scott; Smedsrød, Bård (Journal article; Tidsskriftartikkel; Peer reviewed, 2013)
      Aging is characterized by progressive loss of metabolic and biochemical functions and accumulation of metabolic by-products, including advanced glycation end products (AGEs), which are observed in several pathological conditions. A number of waste macromolecules, including AGEs are taken up from the circulation by endocytosis mainly into liver sinusoidal endothelial cells (LSECs) and Kupffer cells ...

    • Highly oxidized albumin is cleared by liver sinusoidal endothelial cells via the receptors stabilin-1 and -2 

      Holte, Christopher Florian; Szafranska, Karolina Joanna; Kruse, Larissa Dorothea; Simon-Santamaria, Jaione; Li, Ruomei; Svistounov, Dmitri; McCourt, Peter Anthony (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-11-05)
      Oxidized albumin (oxHSA) is elevated in several pathological conditions, such as decompensated cirrhosis, acute on chronic liver failure and liver mediated renal failure. Patient derived oxidized albumin was previously shown to be an infammatory mediator, and in normal serum levels of oxHSA are low. The removal from circulation of oxidized albumins is therefore likely required for maintenance of ...

    • The Relationship between Fenestrations, Sieve Plates and Rafts in Liver Sinusoidal Endothelial Cells 

      Svistounov, Dmitri; Warren, Alessandra; McNerney, Gregory P; Owen, Dylan M.; Zencak, Dusan; Zykova, Svetlana N; Crane, Harry; Huser, Thomas; Quinn, Ronald J.; Smedsrød, Bård; Le Couteur, David G; Cogger, Victoria C (Journal article; Tidsskriftartikkel; Peer reviewed, 2012)
      Fenestrations are transcellular pores in endothelial cells that facilitate transfer of substrates between blood and the extravascular compartment. In order to understand the regulation and formation of fenestrations, the relationship between membrane rafts and fenestrations was investigated in liver sinusoidal endothelial cells where fenestrations are grouped into sieve plates. Three dimensional ...

    • Serum Matrix Metalloproteinase 7 and accelerated glomerular filtration rate decline in a general non-diabetic population 

      Enoksen, Inger Therese T.; Svistounov, Dmitri; Norvik, Jon Viljar; Stefansson, Vidar Tor Nyborg; Solbu, Marit Dahl; Eriksen, Bjørn Odvar; Melsom, Toralf (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-08-26)
      Background. Age-related reduction of glomerular filtration rate (GFR) is a major contributor to the global chronic kidney disease (CKD) epidemic. We investigated whether baseline serum levels of the pro-fibrotic matrix metalloproteinase 2 (MMP2), MMP7 and their inhibitor, tissue inhibitor of metalloproteinase 1 (TIMP1), which mediates fibrosis development in aging animals, were associated with ...

    • Validation of eGFR for Detecting Associations Between Serum Protein Biomarkers and Subsequent GFR Decline 

      Enoksen, Inger Therese Tønsberg; Rinde, Nikoline Balteskard; Svistounov, Dmitri; Norvik, Jon Viljar Porserud; Solbu, Marit Dahl; Eriksen, Bjørn Odvar; Melsom, Toralf (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-08)
      Significance Statement - eGFR from creatinine, cystatin C, or both has been primarily used in search of biomarkers for GFR decline. Whether the relationships between biomarkers and eGFR decline are similar to associations with measured GFR (mGFR) decline has not been investigated. This study revealed that some biomarkers showed statistically significant different associations with eGFR decline ...
