Cholangiocarcinoma (CCA), a cancer of the biliary tract, is a significant health problem in Thailand. Reprogramming of cellular metabolism and upregulation of lipogenic enzymes have been revealed in CCA, but the mechanism is unclear. The current study highlighted the importance of acetyl-CoA carboxylase 1 (ACC1), a rate-limiting enzyme in de novo lipogenesis, on CCA migration.

Background: Intrahepatic cholangiocarcinoma (iCCA) is a cancer arising from intrahepatic bile duct epithelium. An iCCA incidence is increasing worldwide; however, the outcome of the disease is dismal. The linkage between chronic inflammation and iCCA progression is well established, but the roles of granulocyte-macrophage colony-stimulating factor (GM-CSF) remain unrevealed.

Article Synopsis
  • * This study investigates the relationship between increased copies of chromosome 7 (C7) and 17 (C17) in CCA patients and their clinical outcomes, utilizing a method called fluorescence in situ hybridization (FISH).
  • * Findings indicate that higher copy numbers of C7 and/or C17 are associated with lymph node metastasis and shorter overall survival, suggesting these chromosome variations could serve as important markers for prognosis in CCA patients.

Cholangiocarcinoma (CCA) is a highly aggressive malignant tumor that has highest incidence in northeastern Thailand. The survival rate of CCA patients after receiving surgical treatment is quite low. Recently, genetic alterations including chromosome abnormalities have been studied as predictive factors and to aid planning for further treatment.

Recent reports implicate both the liver fluke as a reservoir of within the human gastrointestinal tract and in the pathogenesis of opisthorchiasis-associated cholangiocarcinoma. We postulated that adherence of bacterial ligands to host receptors initiates colonization of the live fluke by and here we aimed to assess the molecular interaction between . and .

We recently developed a modified solid dispersion of curcumin-loaded nanocomplexes (CNCs) in gums which promoted the prolonged and sustained release of curcumin. However, its safety assessment has not yet been investigated. Here, acute and chronic toxicities of CNCs were assayed using mice and hamsters.

Background: Helicobacter pylori (HP) has been detected in the hepatobiliary tract of cholangiocarcinoma (CCA) patients in regions both endemic and non-endemic for Opisthorchis viverrini (OV) infection. However, whether H. pylori infection promotes CCA development remains unknown.

Objective: Choledocholithiasis (CDL), a potential risk for cholangiocarcinoma (CCA) development, is often a consequence of bacterial infection. Thus, the microbial population that contributes to CDL might also be involved in CCA development. We compared the microbiome in bile fluid of CDL patients and CCA patients.

Cholangiocarcinoma (CCA) is a malignancy of the bile duct epithelium. The major problems of this cancer are late diagnosis and a high rate of metastasis. CCA patients in advanced stages have poor survival and cannot be cured with surgery.

Recent reports suggest that the East Asian liver fluke infection, caused by , which is implicated in opisthorchiasis-associated cholangiocarcinoma, serves as a reservoir of . The opisthorchiasis-affected cholangiocytes that line the intrahepatic biliary tract are considered to be the cell of origin of this malignancy. Here, we investigated interactions in vitro among human cholangiocytes, strain NCTC 11637, and the congeneric bacillus, .

Three cholangiocarcinoma (CCA) cell line-formerly named, M156, M213 and M214 have been intensively used with discrepancy of their tumor origins. They were assumed to be originated from three different donors without authentication. To verify the origins of these cell lines, the short tandem repeat (STR) analysis of the currently used cell lines, the cell stocks from the establisher and the primary tumor of a CCA patient were performed.

Cholangiocarcinoma (CCA) is a deadly malignant tumor of the liver. It is a significant health problem in Thailand. The critical obstacles of CCA diagnosis and treatment are the high heterogeneity of disease and considerable resistance to treatment.

Cholangiocarcinoma (CCA) is a poorly prognostic cancer with limited treatment options. Most patients have unresectable tumors when they are diagnosed and the chemotherapies provided are of limited benefit. Prognostic markers are therefore necessary to predict the disease outcome, risk of relapse, or to suggest the best treatment option.

Cholangiocarcinoma is a rare type of cancer which is an increasingly discernible health threat. The disease is usually very difficult in diagnosis and various treatment modalities are typically not effective. Cholangiocarcinoma is a complex and very heterogeneous malignancy characterized by tumor location, different risk factors, molecular profiling, and prognosis.

The treatment of cancer through the induction of natural killer group 2, member D (NKG2D) ligands is of interest, but understanding of mechanisms controlling expression of individual ligand is limited. The major histocompatibility complex (MHC) class I chain related protein B (MICB) is a member of NKG2D ligands. We aimed to investigate the role of 3'-untranslated (3'-UTR) and 5'-untranslated regions (5'-UTR) in post-transcriptional regulation of MICB.

Cholangiocarcinoma is a primary malignant tumor of the bile duct epithelium. Cholangiocarcinoma is usually detected at an advanced stage when successful treatment is no longer possible. As the tumor originates from the bile duct epithelium, bile is an ideal source of tumor biomarkers for cholangiocarcinoma.

Recent reports suggest that Opisthorchis viverrini serves as a reservoir of Helicobacter and implicate Helicobacter in pathogenesis of opisthorchiasis-associated cholangiocarcinoma (CCA). Here, 553 age-sex matched cases and controls, 293 and 260 positive and negative for liver fluke O. viverrini eggs, of residents in Northeastern Thailand were investigated for associations among infection with liver fluke, Helicobacter and hepatobiliary fibrosis.

Intraductal papillary neoplasm of the bile duct (IPNB) is a specific type of bile duct tumor. It has been proposed that it could be the biliary counterpart of the intraductal papillary neoplasm of the pancreas (IPMN-P). This hypothesis is supported by the presence of simultaneous intraductal tumors of both the bile duct and pancreas.

Cholangiocarcinoma (CCA) is generally a rare primary liver tumor of the bile duct with extremely poor clinical outcomes due to late diagnosis. Osteopontin (OPN) is the most abundant expressed gene in intrahepatic CCA and its involvement in tumor aggressiveness suggests it could be a useful prognostic biomarker. However, the prognostic significance of OPN expression in CCA is still controversial.

Purpose: To discover protein markers in chronic/advanced opisthorchiasis for the early detection of Opisthorchis viverrini (OV)-associated cholangiocarcinoma (CCA).

Experimental Design: Liver tissues derived from normal hamsters and those with chronic/advanced opisthorchiasis (n = 5 per group) were subjected to 2DE and LC-MS/MS. Candidate protein expression was confirmed in hamster models and human CCA tissue microarray (TMA) using immunohistochemistry and Western blot.

3 T MRI and (1)H MRS were useful for quantitative investigation of the serial development of hepatobiliary changes in Opisthorchis viverrini infection in hamsters, and the differential diagnosis of cholangiocacinoma (CCA) development from bile duct changes and normal condition is unclear. In this study, we investigated the serial development of hepatobiliary changes and CCAgenesis in O. viverrini-infected and N-nitrosodimethylamine (NDMA) treated hamsters (ON group) using 3 T MRI and (1)H MRS and the results were compared with those either in the O.
