Cholangiocarcinoma (CCA) and hepatocellular carcinoma (HCC) occur with relatively high incidence in Thailand. The secretome, proteins secreted from cancer cells, are potentially useful as biomarkers of the diseases. Proteomic analysis was performed on the secreted proteins of cholangiocarcinoma (HuCCA-1) and hepatocellular carcinoma (HCC-S102, HepG2, SK-Hep-1, and Alexander) cell lines. The sec...
We report a case of Trousseau's syndrome with cholangiocarcinoma complicated by a fatal pulmonary embolism after liver biopsy. A 69-year-old man who presented with right upper quadrant pain was found to have portal vein thrombosis and nonspecific liver hypodensities after imaging by computerized tomography. Following four days of anticoagulation, heparin was held for percutaneous liver biopsy. ...
Cholangiocarcinoma is a rare, sporadic and aggressive type of cancer. The genetic basis of cholangiocarcinoma remains poorly understood. The present study investigated the prognostic role of the N-acetylgalactosaminyltransferase 14 (GALNT14)-rs9679162 genotype, an effective therapeutic response predictor for hepatocellular carcinoma in patients with cholangiocarcinoma receiving surgical resecti...
BACKGROUND To study the methylation status of genes that play a role in the p53-Bax mitochondrial apoptosis pathway and its clinical significance in cholangiocarcinoma. PATIENTS AND METHODS Out of 36 cases cholangiocarcinoma patients from April 2000 to May 2005 were collected.Promoter hypermethylation of DAPK, p14(ARF), and ASC were detected by methylation-specific PCR on cholangiocarcinoma a...
PATIENT Female, 60 FINAL DIAGNOSIS: Cholangiocarcinoma Symptoms: Abdominal pain • abdominal discomfort MEDICATION - Clinical Procedure: - Specialty: Oncology. OBJECTIVE Unusual natural history/clinical course. BACKGROUND Cholangiocarcinoma remains to be a challenging case to diagnose and manage as it usually presents in advanced stage and survival rate remains dismal despite the medical b...
The aim of the present study was to explore possible gene therapy for hilar cholangiocarcinoma by detecting the activation of the Wnt signaling pathway in 4 cholangiocarcinoma cell lines and inhibiting its expression by RNA interference (RNAi) targeting key factors of this pathway. The expression levels of the Wnt pathway-related factors, Wnt2, Wnt3, β-catenin and transcription factor 4, and it...
BACKGROUND The aim of this study was to examine the patterns of expression of epithelial-mesenchymal transition (EMT)-related proteins in intrahepatic cholangiocarcinoma. The clinicopathological and prognostic value of these markers was also evaluated. METHODS We detected the expression status of three EMT-related proteins, ie, E-cadherin, vimentin, and N-cadherin, by immunohistochemistry in ...
INTRODUCTION The "a distintegrin and metalloprotease" (ADAM) family contributes to regulation of the cell-cell and cell-matrix interaction that are critical determinants of malignancy. It also plays important roles in the degradation of the basement membrane during tumor invasion. To evaluate a distinguishing biomarker for hepatocellular carcinoma from cholangiocarcinoma, a disintegrin and meta...
Hepatitis B and C virus (HBV and HCV) infection have been proposed as risk factors for cholangiocarcinoma, but the results are inconsistent through different reports. This study is to carry out a hospital-based case-control study to investigate the association between HBV and HCV infection and cholangiocarcinoma in Turkey. A total of 127 cases and 48 matched controls were included in the study....
Cholangiocarcinomas are cancers that have poor prognosis and limited treatment options. The noncanonical Wnt pathway is mediated predominantly by Wnt 5a, which activates a Ca(2+)-dependent pathway involving protein kinase C, or a Ca(2+)-independent pathway involving the orphan receptor Ror2 and subsequent activation of Jun NH(2)-terminal kinase (JNK). This pathway is associated with growth-supp...
