| 1 | Sporadic versus hereditary gastrinomas of the duodenum and pancreas: Distinct clinico-pathological and epidemiological features显示文摘Gastrinomas are defined as gastrin secreting tumors that are associated with Zollinger-Ellison syndrome (ZES). ZES is characterized by elevated fasting gastrin serum levels, positive secretin stimulation test and clinical symptoms such as recurrent peptic ulcer disease, gastroesophageal re?ux disease and occasional diarrhea. Genetically, nonhereditary (sporadic) gastrinomas are distinguished from hereditary gastrinomas, which are associated with multiple endocrine neoplasia type 1 (MEN1) syndrome. In general, duodenal gastrinomas are small and solitary if they are sporadic and multiple as well as hereditary. The sporadic gastrinomas occur in the duodenum or in the pancreas while the hereditary gastrinomas almost all occur in the duodenum. Our series of 77 sporadic duodenal neuroendocrine tumors (NETs) includes 18 patients (23.4%) with gastrinomas and ZES. Of 535 sporadic NETs in the pancreas collected from the NET archives of the departments of pathology in Zürich, Switzerland, and Kiel, Germany, 24 patients (4.5%) suffered from sporadic pancreatic gastrinomas and ZES. These NETs have to be distinguished fromtumors with immunohistochemical positivity for gastrin but without evidence of ZES. An additional 19 patients suffered from MEN1 and ZES. These patients showed exclusively duodenal gastrinomas, but not pancreatic gastrinomas. The prognosis of sporadic and MEN1- associated duodenal gastrinomas is better than that of pancreatic gastrinomas, since they progress slowly to liver metastasis. In summary, sporadic and MEN1- associated gastrinomas in the duodenum and pancreas show different clinico-pathological and genetic features. The incidence of sporadic duodenal gastrin-producing tumors is increasing, possibly due to optimized diagnostic procedures. In contrast, pancreatic MEN1- associated gastrinomas seem to be extremely rare. A considerable subset of tumors with immunohistochemical expression of gastrin but without evidence of ZES should be designated as functionally inactive NETs expressing gastrin, but not as gastrinomas. | Martin Anlauf Nele Garbrecht Tobias Henopp Anja Schmitt Regina Schlenger Andreas Raffel Markus Krausch Oliver Gimm Claus F Eisenberger Wolfram T Knoefel Henning Dralle Paul Komminoth Philipp U Heitz Aurel Perren Günter Klppel | 2006 | World Journal of Gastroenterology2006,12,34: | 7 |
| 2 | Bcl-x_L and Myeloid cell leukaemia-1 contribute to apoptosis resistance of colorectal cancer cells显示文摘AIM: To explore the role of Bcl-xL and Myeloid cell leukaemia (Mcl)-1 for the apoptosis resistance of colorectal carcinoma (CRC) cells towards current treat-ment modalities. METHODS: Bcl-xL and Mcl-1 mRNA and protein ex-pression were analyzed in CRC cell lines as well as human CRC tissue by Western blot,quantitative PCRand immunohistochemistry. Bcl-xL and Mcl-1 protein expression was knocked down or increased in CRC cell lines by applying specific siRNAs or expression plas-mids,respectively. After modulation of protein expres-sion,CRC cells were treated with chemotherapeutic agents,an antagonistic epidermal growth factor recep-tor (EGFR1) antibody,an EGFR1 tyrosine kinase inhibi-tor,or with the death receptor ligand TRAIL. Apoptosis induction and cell viability were analyzed. RESULTS: Here we show that in human CRC tis-sue and various CRC cell lines both Bcl-xL and Mcl-1 are expressed. Bcl-xL expression was higher in CRC tissue than in surrounding non-malignant tissue,both on protein and mRNA level. Mcl-1 mRNA expression was significantly lower in ma-lignant tissues. However,protein expression was slightly higher. Viability rates of CRC cells were significantly decreased after knock down of Bcl-xL expression,and,to a lower extent,after knock down of Mcl-1 expression. Furthermore,cells with reduced Bcl-xL or Mcl-1 expression was more sensitive towards oxaliplatin-and irinotecan-induced apoptosis,and in the case of Bcl-xL also towards 5-FU-induced apoptosis. On the other hand,upregulation of Bcl-xL by transfec-tion of an expression plasmid decreased chemothera-peutic drug-induced apoptosis. EGF treatment clearly induced Bcl-xL and Mcl-1 expression in CRC cells. Apop-tosis induction upon EGFR1 blockage by cetuximab or PD168393 was increased by inhibiting Mcl-1 and Bcl-xL expression. More strikingly,CD95-and TRAIL-induced apoptosis was increased by Bcl-xL knock down. CONCLUSION: Our data suggest that Bcl-xL and,to a lower extent,Mcl-1,are important anti-apoptotic factors in CRC. Specific downregulation of Bcl-xL is a promising approach to sensitize CRC cells towards chemotherapy and targeted therapy. | Henning Schulze-Bergkamen Roland Ehrenberg Lothar Hickmann Binje Vick Toni Urbanik Christoph C Schimanski Martin R Berger Arno Schad Achim Weber Steffen Heeger Peter R Galle Markus Moehler | 2008 | World Journal of Gastroenterology2008,14,24: | 4 |
