Characterization of the Human Visceral Adipose Tissue Secretome*S
- G. Álvarez-Llamas, E. Szalowska, +6 authors R. Vonk
- Biology, Medicine
- Molecular & Cellular Proteomics
- 1 April 2007
Adipose tissue is an endocrine organ involved in storage and release of energy but also in regulation of energy metabolism in other organs via secretion of peptide and protein hormones (adipokines).… Expand
Biological effects of propionic acid in humans; metabolism, potential applications and underlying mechanisms.
- Sa'ad H. Al-Lahham, M. P. Peppelenbosch, H. Roelofsen, R. Vonk, K. Venema

Undigested food is fermented in the colon by the microbiota and gives rise to various microbial metabolites. Short-chain fatty acids (SCFA), including acetic, propionic and butyric acid, are the… Expand
Copper-induced apical trafficking of ATP7B in polarized hepatoma cells provides a mechanism for biliary copper excretion.
- H. Roelofsen, H. Wolters, M. V. van Luyn, N. Miura, F. Kuipers, R. Vonk
- Biology, Medicine
- Gastroenterology
- 1 September 2000
BACKGROUND & AIMS
Mutations in the ATP7B gene, encoding a copper-transporting P-type adenosine triphosphatase, lead to excessive hepatic copper accumulation because of impaired biliary copper… Expand
Cyclic AMP stimulates sorting of the canalicular organic anion transporter (Mrp2/cMoat) to the apical domain in hepatocyte couplets.
- H. Roelofsen, C. Soroka, D. Keppler, J. Boyer
- Biology, Medicine
- Journal of cell science
- 15 April 1998
The canalicular membrane of rat hepatocytes contains an ATP-dependent multispecific organic anion transporter, also named multidrug resistance protein 2, that is responsible for the biliary secretion… Expand
Increased levels of the multidrug resistance protein in lateral membranes of proliferating hepatocyte-derived cells.
- H. Roelofsen, T. Vos, +5 authors M. Müller
- Biology, Medicine
- Gastroenterology
- 1 February 1997
BACKGROUND & AIMS
The multidrug resistance protein (MRP) functions as an organic anion efflux carrier. Recent studies suggest that hepatocytes contain two mrp homologues, named mrp1 and mrp2,… Expand
Sample Stability and Protein Composition of Saliva: Implications for Its Use as a Diagnostic Fluid
- D. Esser, G. Álvarez-Llamas, Marcel P. de Vries, D. Weening, R. Vonk, H. Roelofsen
- Biology, Medicine
- Biomarker insights
- 1 January 2008
Saliva is an easy accessible plasma ultra-filtrate. Therefore, saliva can be an attractive alternative to blood for measurement of diagnostic protein markers. Our aim was to determine stability and… Expand
In Vivo Chaperone Activity of Heat Shock Protein 70 and Thermotolerance
- E. Nollen, J. Brunsting, H. Roelofsen, L. Weber, H. Kampinga
- Biology, Medicine
- Molecular and Cellular Biology
- 1 March 1999
ABSTRACT Heat shock protein 70 (Hsp70) is thought to play a critical role in the thermotolerance of mammalian cells, presumably due to its chaperone activity. We examined the chaperone activity and… Expand
Differential effects of nitric oxide synthase inhibitors on endotoxin-induced liver damage in rats.
- T. Vos, A. S. Gouw, +7 authors H. Moshage
- Medicine, Biology
- Gastroenterology
- 1 October 1997
BACKGROUND & AIMS
During endotoxemia, expression of inducible nitric oxide synthase (iNOS) and nitric oxide production in the liver is increased. NO has been suggested to have a hepatoprotective… Expand
Impaired hepatocanalicular organic anion transport in endotoxemic rats.
- H. Roelofsen, B. Schoemaker, C. Bakker, R. Ottenhoff, P. Jansen, R. P. Elferink
- Chemistry, Medicine
- The American journal of physiology
- 1 September 1995
To investigate the mechanism of sepsis-associated hyperbilirubinemia we have studied hepatocanalicular transport of organic anions in a rat model of endotoxemia. Rats were injected intravenously with… Expand
Proteomics analysis of Hodgkin lymphoma: identification of new players involved in the cross-talk between HRS cells and infiltrating lymphocytes.

- Biology, Medicine
- Blood
- 1 November 2007
Hodgkin and Reed-Sternberg (HRS) cells in Hodgkin lymphoma (HL) secrete factors that interact with inflammatory background cells and may serve as biomarkers for disease activity. To detect new… Expand
