MicroRNA, an endogenous noncoding RNA modulating gene expression, is a key molecule that by its dysregulation plays roles in inflammatory-driven carcinogenesis. This study aimed to investigate the role of oncomiR miR-21 and its target, the programmed cell death 4 (PDCD4) in tumor growth and metastasis of the liver fluke Opisthorchis viverrini-associated(More)
Improving therapy for patients with cholangiocarcinoma (CCA) presents a significant challenge. This is made more difficult by a lack of a clear understanding of potential molecular targets, such as deregulated kinases. In this work, we profiled the activated kinases in CCA in order to apply them as the targets for CCA therapy. Human phospho-receptor(More)
Nitrative and oxidative DNA damage plays an important role in inflammation-related carcinogenesis. Chronic inflammation such as parasite infection and primary sclerosing cholangitis can be an etiological factor of cholangiocarcinoma. Using a proteomic approach and double-fluorescent staining, we identified high expression and colocalization of albumin and(More)
Epithelial–mesenchymal transition (EMT) is characterized by the loss of epithelial markers and the gain of mesenchymal markers. EMT is believed to be a major mechanism supporting cancer cell metastasis. The activation of EMT can be induced by various types of inflammatory cytokines including transforming growth factor β (TGF-β) whereas bone morphogenetic(More)
Our previous report showed that platelet-derived growth factor (PDGF) and related genes were upregulated in a Syrian hamster model and could be detected in all human cholangiocarcinoma (CCA) tissues. We therefore hoped that PDGF could be used as a diagnostic and prognostic marker. We analyzed 78 samples of human CCA and adjacent tissues for PDGF and related(More)
Cholangiocarcinoma (CCA) is the primary cancer of the bile duct system. The role of bile duct tissue microbiomes in CCA tumorigenesis is unestablished. To address this, sixty primary CCA tumors and matched normals, from both liver fluke (Opisthorchis viverrini) associated (OVa, n=28) and non-O. viverrini associated (non-OVa, n=32) cancers, were profiled(More)
The Wnt/β-catenin signaling pathway is pathologically activated in cholangiocarcinoma (CCA). Here, we determined the expression profile as well as biological role of activated Wnt/β-catenin signaling in CCA. The quantitative reverse transcription polymerase chain reaction demonstrated that Wnt3a, Wnt5a, and Wnt7b mRNA were significantly higher in CCA(More)
Cholangiocarcinoma (CCA) is the second most common-primary liver cancer. The difficulties in diagnosis limit successful treatment of CCA. At present, histological investigation is the standard diagnosis for CCA. However, there are some poor-defined tumor tissues which cannot be definitively diagnosed by general histopathology. As molecular signatures can(More)
Cholangiocarcinoma (CCA) is an extremely aggressive cancer that is usually fatal. Although globally morbidity and mortality are increasing, knowledge of the disease remains limited. The Mekong region of Southeast Asia, and particularly the northeast of Thailand, has by far the highest incidence of CCA worldwide with 135.4 per 100,000 among males and 43.0(More)
Tumor progression is characterized by loss of cell adhesion and increase of invasion and metastasis. E-cadherin, a cell adhesion molecule, is frequently downregulated and has been proposed as an important mediator in epithelial-mesenchymal transition (EMT) in tumors. In this study, we investigated the expression of E-cadherin and its association with cancer(More)
