Zinc-fingers and homeoboxes 1 (ZHX1) is a transcription repressor that has been associated with the progressions of hepatocellular carcinoma, gastric cancer, and breast cancer. However, the functional roles of ZHX1 in cholangiocarcinoma (CCA) have not been determined. We investigated the expression and roles of ZHX1 during the proliferation, migration, and invasion of CCA cells. In silico analy...

Ranking relevance degree information is widely utilized in the ranking models of information retrieval applications, such as text and multimedia retrieval, question answering, and visual search reranking. However, existing feature dimensionality reduction methods neglect this kind of valuable potential supervised information. In this paper, we extend the pairwise constraints from the traditiona...

BACKGROUND Cholangiocarcinoma (CCA) is the second most common primary liver cancer, being characterized by its late diagnosis and fatal outcome. Recent epidemiological reports indicate an increasing worldwide incidence of intrahepatic CCA but a decreasing incidence of extrahepatic CCA. METHODS In this review, we present an overview of the incidence and epidemiology of CCA and possible strateg...

Cholangiocarcinoma (CCA) is a devastating disease due to resistance to traditional chemotherapies and radiotherapies. New therapeutic strategies against CCA are urgently needed. This study investigated the role of lipocalin-2 (LCN2) in human cholangiocarcinoma as a potential therapeutic target and diagnostic marker. So far, the role of LCN2 in cancer is still controversial and studies regarding...

Genetic risk factors for cholangiocarcinoma (CCA) remain poorly understood. We assessed the effect of single-nucleotide polymorphisms (SNPs) of genes modulating inflammation or carcinogenesis on CCA risk and survival. We conducted a case-control, candidate gene association study of 370 CCA patients and 740 age-, sex-, and residential area-matched healthy controls. Eighteen functional or putativ...

Cholangiocarcinoma (CCA) is a heterogeneous group of malignancies that may develop at any level of the biliary tree. CCA is currently classified into intrahepatic (iCCA), perihilar (pCCA) and distal (dCCA) on the basis of its anatomical location. Notably, although these three CCA subtypes have common features, they also have important inter- and intra-tumor differences that can affect their pat...

In order to determine the diagnostic and prognostic value of miR-26a in Cholangiocarcinoma (CCA), we compared miR-26a levels in serum from 66 CCA patients and 66 healthy controls, which was followed by serum analysis between the pre-operative serum and post-operative serum of these CCA patients. We found the concentration levels of miR-26a in serum of CCA patients were significantly higher than...

Altered miRNA expression could be a determinant of cancer development and/or progression. We aimed to study the role of oncomir miR-21 and tumor suppressor let-7a in the genesis of Opisthorchiasis-associated cholangiocarcinoma (CCA). The results showed that miR-21 was up-regulated while let-7a was down-regulated during cholangiocarcinogenesis in the hamster model and also in human CCA samples. ...

We summarize recent work on learning improved acoustic features, using articulatory measurements that are available for training but not at test time. The goal is to improve recognition using articulatory information, but without explicitly solving the difficult acoustics-to-articulation inversion problem. We formulate the problem as learning a (linear or nonlinear) transformation of standard a...

Cholangiocarcinoma (CCA) is a very aggressive and lethal tumor, which arises from the epithelial cells of bile ducts. CCA comprises about 3% of all gastrointestinal malignancies and its incidence is on the rise in the recent years. Anatomically, it is classified into intrahepatic, perihilar, or extrahepatic (distal) CCA. There are a number of risk factors associated with CCA including primary s...
