BACKGROUND AND AIMS: Cholangiocarcinoma (CCA) is an aggressive tumor type affecting cholangiocytes. CCAs frequently arise under certain cholestatic liver conditions. Intrahepatic accumulation of bile acids may facilitate cocarcinogenic effects by triggering an inflammatory response and cholangiocyte proliferation. Here, the role of bile acid receptors FXR and TGR5 in CCA progression was evaluated. METHODS: FXR and TGR5 expression was determined in human CCA tissues and cell lines...

Wip1 has been shown to correlate with the metastasis/invasion of several tumors. This study was designed to investigate the clinical significance and biological function of Wip1 in intrahepatic cholangiocarcinoma (ICC). The expression of Wip1 was investigated in sixty human ICC biopsy samples by immunohistochemistry. Transient and stable knockdown of Wip1 in two human ICC cells (ICC-9810 and SSP25) were established using short hairpin RNA expression vector. Immunohistochemistry revealed that Wip1 was up-regulated in human ICC tissues (47/60, 78...

OBJECTIVES: Role of 18-FDG PET/CT had been well established in other more prevalent malignancies such as colorectal and lung cancer; however, this is not as well defined in cholangiocarcinoma. Literature focusing on the prognostic values of preoperative PET/CT for resectable cholangiocarcinoma is scarce. METHOD: This is a retrospective cohort of 66 consecutive patients who had received curative resection for cholangiocarcinoma from 2010 to 2015. All patients had preoperative 18-FDG PET/CT performed...

Osthole is a natural coumarin isolated from Umbelliferae plant monomers. Previous research has indicated that osthole exerts a wide variety of biological effects, acting as anti-seizure, anti-osteoporosis and anti-inflammation. However, the regulatory effect and related molecular mechanism of osthole in intrahepatic cholangiocarcinoma (ICC) remain unknown. In the present study, the authors found that osthole inhibited ICC cell lines in a dose- and time-dependent manner. Osthole also significantly induced mitochondrial-dependent apoptosis by upregulating Bax, cleaved caspase-3, cleaved caspase-9, and cleaved poly ADP-ribose polymerase expression, and by downregulating Bcl-2 expression...

Cholangiocarcinoma (CCA) and its subtypes (mucin- and mixed-CCA) arise from the neoplastic transformation of cholangiocytes, the epithelial cells lining the biliary tree. CCA has a high mortality rate owing to its aggressiveness, late diagnosis and high resistance to radiotherapy and chemotherapeutics. We have demonstrated that CCA is enriched for cancer stem cells which express epithelial to mesenchymal transition (EMT) traits, with these features being associated with aggressiveness and drug resistance. TGF-β signaling is upregulated in CCA and involved in EMT...

BACKGROUND: Locoregional extension of intrahepatic cholangiocarcinoma (ICC) at the time of diagnosis results in a low resectability rate and poor prognosis. The aim of this retrospective study was to assess the efficacy of neoadjuvant chemotherapy for locally advanced ICC. METHODS: All consecutive patients with ICC between 2000 and 2013 were included prospectively in a single-centre database and analysed retrospectively. Patients with locally advanced ICC considered as initially unresectable received primary chemotherapy, followed by surgery in those with secondary resectability...

BACKGROUND: DNA methylation changes occurring in cancer cells are featured with both promoter CpG island hypermethylation and diffuse genomic hypomethylation. Long interspersed element-1 (LINE-1) is repeated in an interspersed manner with an estimated 500,000 copies per genome. LINE-1 has its CpG sites of the 5' untranslated region methylated heavily in normal cells and undergoes demethylation in association with cancerization. However, little information is available regarding LINE-1 hypomethylation and its prognostic implication in intrahepatic cholangiocarcinomas...

Bile salts represent signalling molecules with a variety of endocrine functions. Bile salt effects are mediated by different receptor molecules, comprising ligand-activated nuclear transcription factors as well as G protein-coupled membrane-bound receptors. The farnesoid X receptor (FXR) and the plasma membrane-bound G protein-coupled receptor TGR5 (Gpbar-1) are prototypic bile salt receptors of both classes and are highly expressed in the liver including the biliary tree as well as in the intestine. In liver, TGR5 is localized in different non-parenchymal cells such as sinusoidal endothelial cells, Kupffer cells, hepatic stellate cells and small and large cholangiocytes...

Cholangiocarcinoma (CCA) represents a diverse group of epithelial cancers associated with the biliary tract, and can best be stratified anatomically into intrahepatic (iCCA), perihilar (pCCA) and distal (dCCA) subsets. Molecular profiling has identified genetic aberrations associated with these anatomic subsets. For example, IDH catalytic site mutations and constitutively active FGFR2 fusion genes are predominantly identified in iCCA, whereas KRAS mutations and PRKACB fusions genes are identified in pCCA and dCCA...

Primary sclerosing cholangitis (PSC) is an idiopathic cholangiopathy strongly associated with inflammatory bowel disease (IBD) and characterized by cholestasis, chronic immune infiltration and progressive fibrosis of the intrahepatic and extrahepatic bile ducts. PSC confers a high risk of cholangiocarcinoma (CCA) with PSC-CCA representing the leading cause of PSC-associated mortality. PSC-CCA is derived from cholangiocytes and associated progenitor cells - a heterogeneous group of dynamic epithelial cells lining the biliary tree that modulate the composition and volume of bile production by the liver...
