However, the effect of Raf kinase inhibitor

protein (RKIP) on cholangiocarcinoma cell biologic behaviors is not clear yet. Methods: RKIP and CK19 expressions in extrahepatic cholangiocarcinoma patients’ tissues were detected by immunohistochemistry. SiRNA or overexpression adenoviral vector of RKIP were used to infect cholangiocarcinoma cell line RBE. RKIP gene or protein expressions were detected by RT-qPCR or Western blotting. Cells were assayed for proliferation, apoptosis, invasion and migration. Results: RKIP expression was negatively correlated with lymph node or distant metastasis. RKIP siRNA treatment promoted RBE cell invasion, but RKIP overexpression Vorinostat manufacturer in cells prevented cell invasion. In RKIP-RNAi-AD group cells grew faster than the control (NC-RNAi-GFP-AD) group; and in RKIP-AD group cells grew slower than the control (GFP-AD) group. Conclusion: RKIP protein expression in cholangiocarcinoma cells may relate to better survival time. It delays cholangiocarcinoma development and progression by inhibiting cholangiocarcinoma LY294002 cell invasion

and migration. Key Word(s): 1. RKIP; 2.

Endoscopic snare medchemexpress papillectomy (ESP) may be a minimally invasive solution to treat these lesions. This retrospective single centre study evaluates the safety

and outcome of ESP for ampullary tumors. Methods: Patients with ampullary tumors treated with ESP during 6-years (Feb 2007 to Jan 2013) identified from ERCP database. All underwent pre-ESP EUS and relevant imaging to confirm localized disease and suitability for procedure. ESP was performed using a diathermy snare followed by biliary and pancreatic stenting – removed at 4 – 6 weeks with base biopsies for residual tumor. Patients with histology adenocarcinoma were counseled for either close follow-up or surgical resection & with benign histology were followed up. Follow up done at 3, 6, 12, 18, and 24 months, yearly thereafter. Results: 36patients underwent ESP, mean age 63 years (33 – 83), males – 23..Mean tumor diameter was 18 mm ( 7 – 37).
