Department of Experimental Internal Medicine, Academic Medical Center, Meibergdreef 9, 1105 AZ Amsterdam, The Netherlands
Gastroenterology 121:79-90. 2001..The aim of this study was to investigate whether leptin is a growth factor for colonic epithelial cells...
Bone morphogenetic protein 2 is expressed by, and acts upon, mature epithelial cells in the colonJames C H Hardwick
Department of Experimental Internal Medicine, Academic Medical Center, Amsterdam, The Netherlands
Gastroenterology 126:111-21. 2004..We investigated the role of BMP2 in the colon...
DNA array analysis of the effects of aspirin on colon cancer cells: involvement of Rac1James C H Hardwick
Department of Experimental Internal Medicine, Academic Medical Center, Meibergdreef 9, 1105 AZ, Amsterdam, The Netherlands
Carcinogenesis 25:1293-8. 2004..Furthermore, they point towards a role for Rac1 in the action of aspirin in colon cancer...
Sonic hedgehog regulates gastric gland morphogenesis in man and mouseG R van den Brink
Department of Experimental Internal Medicine, Academic Medical Center, Meibergdreef 9, 1105 AZ Amsterdam, The Netherlands
Gastroenterology 121:317-28. 2001..We investigated whether Sonic hedgehog (Shh), an established polarizing signal protein during development, is expressed and functional in the adult human and murine stomach...
The effect of statins in colorectal cancer is mediated through the bone morphogenetic protein pathwayLiudmila L Kodach
Center for Experimental and Molecular Medicine, Academic Medical Center, Amsterdam, The Netherlands
Gastroenterology 133:1272-81. 2007..Statins induce bone morphogenetic protein (BMP) expression in bone cells. We have previously shown that BMPs act as tumor suppressors in CRC. We hypothesized that the action of statins in CRC involves the induction of BMPs...
NF-kappaB, p38 MAPK and JNK are highly expressed and active in the stroma of human colonic adenomatous polypsJ C Hardwick
Department of Experimental Internal Medicine, Academic Medical Center, Amsterdam, The Netherlands
Oncogene 20:819-27. 2001..In the case of NF-kappaB this coincides with the cellular localisation of COX-2. These results support evidence that NSAIDs may act through effects on stromal cells rather than epithelial cells...
Transanal endoscopic microsurgery versus endoscopic mucosal resection for large rectal adenomas (TREND-study)Frank J C van den Broek
Dept of Gastroenterology and Hepatology, Academic Medical Centre, Amsterdam, The Netherlands
BMC Surg 9:4. 2009..Furthermore, EMR appears to be associated with fewer complications.The aim of this study is to compare the cost-effectiveness and cost-utility of TEM and EMR for the resection of large rectal adenomas...
Violacein synergistically increases 5-fluorouracil cytotoxicity, induces apoptosis and inhibits Akt-mediated signal transduction in human colorectal cancer cellsLiudmila L Kodach
Laboratory for Experimental Internal Medicine, Academic Medical Center, Amsterdam, The Netherlands
Carcinogenesis 27:508-16. 2006..Taken together, our findings suggest that violacein will be active in the treatment of colorectal tumors and offers new prospects for overcoming 5-FU resistance...
Indian Hedgehog is an antagonist of Wnt signaling in colonic epithelial cell differentiationGijs R van den Brink
Department of Experimental Internal Medicine, Academic Medical Center, Amsterdam, The Netherlands
Nat Genet 36:277-82. 2004..These data identify a new Wnt-Hh axis in colonic epithelial renewal...
Altered bone morphogenetic protein signalling in the Helicobacter pylori-infected stomachS A Bleuming
Department of Experimental Internal Medicine, Academic Medical Center, Amsterdam, The Netherlands, and Department of Gastroenterology and Hepatology, Geneva University Hospital, Switzerland
J Pathol 209:190-7. 2006..The data suggest that morphological changes in epithelial histology may result from alterations in the morphogenetic landscape secondary to changes in the cellular composition of the lamina propria...
Narrow-band imaging compared with conventional colonoscopy for the detection of dysplasia in patients with longstanding ulcerative colitisE Dekker
Department of Gastroenterology and Hepatology, Academic Medical Center, Amsterdam, The Netherlands
Endoscopy 39:216-21. 2007..The aim of this study was to compare the accuracy of narrow-band imaging (NBI), a new imaging technique, with standard colonoscopy for the detection of neoplasia in patients with longstanding ulcerative colitis...
The bone morphogenetic protein pathway is active in human colon adenomas and inactivated in colorectal cancerLiudmila L Kodach
Center for Experimental and Molecular Medicine, Academic Medical Center, Amsterdam, The Netherlands
Cancer 112:300-6. 2008..Bone morphogenetic proteins (BMPs), a subgroup within the TGFbeta superfamily, recently also have been implicated in CRC, but their precise role in CRC has yet to be investigated...
Combining autofluorescence imaging and narrow-band imaging for the differentiation of adenomas from non-neoplastic colonic polyps among experienced and non-experienced endoscopistsFrank J C van den Broek
Department of Gastroenterology and Hepatology, Academic Medical Center, University of Amsterdam, Amsterdam, The Netherlands
Am J Gastroenterol 104:1498-507. 2009..In this study, we aimed to assess the interobserver variability and accuracy of HR-WLE, NBI, and AFI for polyp differentiation and to evaluate the combined use of AFI and NBI...
Clinical evaluation of endoscopic trimodal imaging for the detection and differentiation of colonic polypsFrank J C van den Broek
Department of Gastroenterology and Hepatology, Academic Medical Center, Amsterdam, The Netherlands
Clin Gastroenterol Hepatol 7:288-95. 2009..This was a randomized trial of tandem colonoscopies. The study was performed at the Academic Medical Center in Amsterdam...
The bone morphogenetic protein pathway is inactivated in the majority of sporadic colorectal cancersLiudmila L Kodach
Department of Gastroenterology, Leiden University Medical Center, Leiden, The Netherlands
Gastroenterology 134:1332-41. 2008..The finding of bone morphogenetic protein (BMP) receptor 1a mutations in juvenile polyposis suggests that BMPs are important in colorectal cancer (CRC). We investigated the BMP pathway in sporadic CRC...
