(Pro)Renin Receptor Antagonism Attenuates High-Fat-Diet–Induced Hepatic Steatosis

Gayban, A.J.B. (author), Souza, L.A.C. (author), Cooper, S.G. (author), Regalado, E. (author), Kleemann, R. (author), Earley, Y.F. (author)

Non-alcoholic fatty liver disease (NAFLD) comprises a spectrum of liver damage directly related to diabetes, obesity, and metabolic syndrome. The (pro)renin receptor (PRR) has recently been demonstrated to play a role in glucose and lipid metabolism. Here, we test the hypothesis that the PRR regulates the development of diet-induced hepatic...

Stains on wood are often unwanted in outdoor applications, dark stain formation however is essential to the development of a new protective, self-healing and decorative biotreatment for wood. The biotreatment is based on the formation of surface covering mould staining on linseed oil treated pine sapwood during outdoor exposure. This specific...

van der Tuin, S.J. (author), Kühnast, S. (author), Berbée, J. (author), Verschuren, L. (author), Pieterman, E.J. (author), Havekes, L.M. (author), van der Hoorn, J.W. (author), Rensen, P.C. (author), Jukema, J.W. (author), Princen, H.M. (author), Willems van Dijk, K. (author), Wang, Y. (author)

Recently, we showed in APOE*3-Leiden.CETP mice that anacetrapib attenuated atherosclerosis development by reducing (V)LDL-C rather than by raising HDL-C. Here, we investigated the mechanism by which anacetrapib reduces (V)LDL-C and whether this effect was dependent on the inhibition of CETP. APOE*3-Leiden.CETP mice were fed a Western type diet...

A long-term goal of numerous research projects is to identify biomarkers for in vitro systems predicting toxicity in vivo. Often, transcriptomics data are used to identify candidates for further evaluation. However, a systematic directory summarizing key features of chemically influenced genes in human hepatocytes is not yet available. To bridge...

Background:Prostate cancer is the most commonly diagnosed cancer in men in Europe and the United States. Numerous studies have indicated genetics to have a major role in the aetiology of this disease; as much as 42% of the risk may be explained by heritable factors. Genome-wide association studies have detected an association between prostate...

INTRODUCTION: The colonic mucus layer plays an important role in the protection of the intestinal epithelium and mainly consists of mucin glycoproteins (primarily MUC2 in the colon) trefoil factor 3 (TFF3) and secretory IgA. Butyrate is a major end product of fermentation of dietary fibres and is associated with beneficial effects on colonic...

de Haan, W. (author), de Vries-van der Weij, J. (author), Mol, I.M. (author), Hoekstra, M. (author), Romijn, J.A. (author), Jukema, J.W. (author), Havekes, L.M. (author), Princen, H.M.G. (author), Rensen, P.C.N. (author), TNO Kwaliteit van Leven (author)

Pregnane X receptor (PXR) agonism has been shown to affect multiple steps in both the synthesis and catabolism of HDL, but its integrated effect on HDL metabolism in vivo remains unclear. The aim of this study was to evaluate the net effect of PXR agonism on HDL metabolism in ApoE*3-Leiden (E3L) and E3L.CETP mice, well-established models for...

Pseudomonas putida S12 is well known for its remarkable solvent tolerance. Transcriptomics analysis of this bacterium grown in toluene-containing chemostats revealed the differential expression of 253 genes. As expected, the genes encoding one of the major solvent tolerance mechanisms, the solvent efflux pump SrpABC and its regulatory genes...

Fiber-chimeric adenoviruses expressing fibers from serotype 16 and 50 improve gene transfer to human pancreatic adenocarcinoma

Kuhlmann, K.F.D. (author), van Geer, M.A. (author), Bakker, C.T. (author), Dekker, J.E.M. (author), Havenga, M.J.E. (author), Oude Elferink, R.P.J. (author), Gouma, D.J. (author), Bosma, P.J. (author), Wesseling, J.G. (author), TNO Kwaliteit van Leven (author)

Survival of patients with pancreatic cancer is poor. Adenoviral (Ad) gene therapy employing the commonly used serotype 5 reveals limited transduction efficiency due to the low amount of coxsackie-adenovirus receptor on pancreatic cancer cells. To identify fiber-chimeric adenoviruses with improved gene transfer, a library of Ad vectors based on...

Polymorphisms in genes related to activation or detoxification of carcinogens might interact with smoking to increase renal cancer risk: Results from The Netherlands Cohort Study on diet and cancer

Smits, K.M. (author), Schouten, L.J. (author), van Dijk, B.A.C. (author), van Houwelingen, K. (author), van de Hulsbergen-Kaa, C.A. (author), Kiemeney, L.A.L.M. (author), van Houwelingen, K. (author), Goldbohm, R.A. (author), Oosterwijk, E. (author), van den Brandt, P.A. (author), TNO Kwaliteit van Leven (author)

Metabolic gene polymorphisms have previously been suggested as risk factors for renal cell carcinoma (RCC). These polymorphisms are involved in activation or detoxification of carcinogens in cigarette smoke which is another RCC risk factor. We evaluated gene-environment interactions between CYP1A1, GSTμ1 and smoking in a large population-based...
