Abstract
Intrahepatic cholangiocarcinoma (ICC) is a fatal disease and the molecular mechanism of its progression remains unknown. Aurora Kinase B (AURKB) is a central regulator of chromosome separation and cytokinesis and is abnormally expressed in a variety of cancer cells. This research aimed to explore the effect of AURKB in occurrence and metastasis of ICC. We found that AURKB showed a progressive up-regulation pattern from normal bile duct tissue to ICC with high invasion. Our data showed that AURKB significantly promoted ICC cell proliferation, induced epithelial-mesenchymal transition (EMT), migration and invasion through gain- and loss- of function experiments. In vivo results consistently showed that AURKB up-regulation not only promoted tumor growth, but also promoted tumor metastasis. Importantly, we discovered that AURKB regulates the expressions of EMT-related genes via PI3K/AKT signaling axis. Herein, our results suggest that AURKB induced EMT through the activation of PI3K/AKT signaling pathway is critical to the progression of ICC, which may be a prospective therapeutic treatment for overcoming ICC metastasis and progression.

Abstract
BACKGROUND The incidence of cholangiocarcinoma (CCA) has risen in recent years, and it has become a significant health burden worldwide. However, the mechanisms underlying tumorigenesis and progression of this disease remain largely unknown. An increasing number of studies have demonstrated crucial biological functions of epigenetic modifications, especially DNA methylation, in CCA. The present study aimed to identify and analyze methylation-regulated differentially expressed genes (MeDEGs) involved in CCA tumorigenesis and progression by bioinformatics analysis. METHODS The gene expression profiling dataset (GSE119336) and gene methylation profiling dataset (GSE38860) were obtained from the Gene Expression Omnibus (GEO) database. Differentially expressed genes (DEGs) and differentially methylated genes (DMGs) were identified using the limma packages of R and GEO2R, respectively. The MeDEGs were obtained by overlapping the DEGs and DMGs. Functional enrichment analyses of these genes were then carried out. Protein-protein interaction (PPI) networks were constructed using STRING and visualized in Cytoscape to determine hub genes. Finally, the results were verified based on The Cancer Genome Atlas (TCGA) database. RESULTS We identified 98 hypermethylated, downregulated genes and 93 hypomethylated, upregulated genes after overlapping the DEGs and DMGs. These genes were mainly enriched in the biological processes of the cell cycle, nuclear division, xenobiotic metabolism, drug catabolism, and negative regulation of proteolysis. The top nine hub genes of the PPI network were F2, AHSG, RRM2, AURKB, CCNA2, TOP2A, BIRC5, PLK1, and ASPM. Moreover, the expression and methylation status of the hub genes were significantly altered in TCGA. CONCLUSIONS Our study identified novel methylation-regulated differentially expressed genes (MeDEGs) and explored their related pathways and functions in CCA, which may provide novel insights into a further understanding of methylation-mediated regulatory mechanisms in CCA.

Abstract
Expression profile analysis of cell cycle biomarkers provides a powerful index of the proliferative state of tumors, which is linked to disease aggressiveness. We investigated the impact of the biomarkers of S-G2-M phases of cell cycle, Aurora kinase B (AURKB) and geminin (GMNN), on disease progression in neuroblastomas. The expression of AURKB and GMNN was studied by immunostaining 84 neuroblastomas. A proliferation index (PI) was obtained on scanned immunostained slides using image analysis software. The median PI was 8.5 % for AURKB- and 16.8 % for GMNN-stained slides with a high correlation between the two (r s = 0.72, P < 0.001). The PI for both markers was significantly higher in neuroblastomas from patients with unfavorable clinical (high-risk group, advanced stage, age ≥18 months at presentation, primary abdominal compared to extra-abdominal sites), biological (MYCN amplification, 1p deletion, 17q gain), and pathological (undifferentiated or poorly differentiated status, high mitosis-karyorrhexis index, [MKI], unfavorable histology) factors. Using Cox regression models, a higher-than-median AURKB and GMNN PI was associated with a significantly shorter overall survival (OS) and event-free survival (EFS) in univariable analysis. In multivariable analysis, a high AURKB PI was associated with significantly shorter OS and EFS, independent of MYCN amplification, and significantly shorter EFS, independent of MKI. High GMNN PI was also associated with significantly shorter OS and EFS after adjusting for MYCN amplification but failed to reach statistical significance after adjusting for MKI. Our study shows that in neuroblastomas, AURKB- or GMNN-based PI provides valuable prognostic information and high PI indicates aggressive disease.

Abstract
Cholangiocarcinoma is one of the most aggressive types of malignancy, and is associated with poor patient prognosis. Recent findings suggest that a decrease in pleckstrin homology-like domain family A, member 1 (PHLDA1) expression is significant in the induction of cell migration and tumor invasion. The clinicopathological significance of the expression of PHLDA1, and its potential correlation with the expression of CD133 in cholangiocarcinoma have remained to be elucidated. In the present study, PHLDA1 protein expression was investigated by immunohistochemical analysis of 218 cholangiocarcinoma tissue samples, as well as 30 para-neoplastic and 20 normal bile ducts. The expression status of PHLDA1 and CD133 was determined, and these results were analyzed against the age, gender, tumor location and size, histological grade, clinical stage and overall mean survival time of the patients. The expression of PHLDA1 protein was markedly decreased in 35.3% of cholangiocarcinomas, compared with that of the para-neoplastic and normal cholangiocytes. Carcinomas with loss of expression of PHLDA1 were significantly correlated with the tumor site (P=0.001), histological grade (P=0.020) and clinical stage (P=0.0001), but not with age (P=0.085), gender (P=0.456) or size (P=0.413), respectively. Kaplan-Meier survival analysis indicated that the loss of expression of PHLDA1 was significantly correlated with the overall survival time (Log rank=193.861; P=0.0001). Furthermore, the expression of PHLDA1 was found to be inversely correlated with the expression of CD133 (γ=-0.142; P=0.036). These findings suggested that the decreased expression of PHLDA1 may be significant in the carcinogenesis and progression of cholangiocarcinoma, and may represent a novel adjunct marker of disease prognosis.

Abstract
The human homologue of the mouse double minute 2 (MDM2) is known to be overexpressed in a variety of human malignancies. As one of E3 ubiquitin-protein ligases, MDM2 interacts with the tumour suppressor p53 by mediating ubiquitination and degradation of p53. Since abnormally expressed proteins can induce autoimmune response, to further examine whether sera from patients with esophageal squamous cell carcinoma (ESCC) exhibited immunoreactivity against MDM2 and p53, autoantibody responses to MDM2 and p53 were evaluated by enzyme-linked immunosorbent assay (ELISA) in sera from patients with ESCC and normal individuals. Positive results were also confirmed by Western blotting and indirect immunofluorescence assay. The results demonstrated that the positive rate of autoantibody against p53 and MDM2 in ESCC sera was 22.9% (36/157) and 14.0% (22/157), whereas this rate was 0% (0/85) and 1.2% (1/85), respectively, in normal individuals. Some of the sera with antibodies specific for MDM2 also contained antibodies against p53. And there was an increase of positive antibody reactions reaching a frequency of 35% (55/157) combination with MDM2 and p53. This was significantly higher than the frequency of antibodies in normal individuals (P < 0.01). Our preliminary results suggest that autoantibodies against MDM2 and p53 may be useful serum biomarkers in the immunodiagnosis of ESCC.

Abstract
BACKGROUND AND AIM Cholangiocarcinomas of different locations differ in growth patterns, symptoms, treatment response, and survival. Still, they are regarded in many studies as a uniform malignancy. Because intra- (iCCA) and extrahepatic (eCCA) cholangiocarcinoma display such differences, we performed a systematic review and meta-analysis to analyze differences in the immunohistochemical profile of these tumors. METHODS In February 2014, we searched the two main medical literature databases MEDLINE and EMBASE. We extracted risk ratios and 95% confidence intervals from the identified studies and performed random-effects model meta-analyses in accordance with PRISMA and REMARK guidelines. RESULTS A total of 54 cohort studies, including 4458 patients and studying 102 individual markers met the inclusion criteria. Of the 57 markers that were evaluated in more than 30 iCCA and eCCA patients, 18 showed a statistically significant difference in expression between iCCA and eCCA. Biomarkers expressed differently between iCCA and eCCA included potential targets of therapy: EGFR, c-erbB-2 and VEGF-A. Several markers showed no statistical difference but large 95% confidence intervals, suggesting insufficient sample size. CONCLUSIONS This systematic review shows differences in marker expression between iCCA and eCCA. Consequently, patients with iCCA and eCCA may benefit from different treatment strategies.

Abstract
BACKGROUND AND AIM Biliary tract carcinomas (BTCs) are difficult to diagnose and treat. Epidermal growth factor receptor (EGFR) represents a therapeutic target for the BTCs. Mutations of the EGFR gene and the activation of its downstream pathways, including KRAS and BRAF, predict the sensitivity to anti-EGFR treatment. The aims of this study were to analyze the EGFR, KRAS and BRAF mutations in BTCs and their association with clinical outcomes. METHODS Paraffin-embedded specimens containing 137 BTCs resected at the National Taiwan University Hospital between 1995 and 2004 were analyzed. The exons 18-21 of EGFR gene, the codon 12, 13 and 61 of KRAS gene, and BRAF V600E mutation were analyzed. We examined the correlation between these mutations and the overall survival, tumor location, stage, and differentiation in BTCs. RESULTS Thirteen (9.5%) BTC patients had EGFR mutations while 23 (16.8%) patients had KRAS mutations. Only one patient had BRAF mutation. Factors influencing survival on univariate analysis were tumor stage, tumor differentiation, and EGFR mutation. On multivariate analysis, EGFR mutation and tumor stage were independent prognostic factors. A correlation between KRAS or BRAF mutations and prognosis was not observed. CONCLUSIONS EGFR and KRAS mutations are not uncommon in BTCs. BRAF mutation is rare in BTCs. EGFR mutation was an independent prognostic marker in BTCs in addition to tumor stage and differentiation. No simultaneous EGFR and KRAS mutations in extrahepatic cholangiocarcinoma and gallbladder carcinoma were found. EGFR and KRAS mutations should be evaluated when tailoring molecular-targeted therapy to patients with BTCs.

Abstract
We identified novel helper epitope peptides of Survivin cancer antigen, which are presented to both HLA-DRB1*01:01 and DQB1*06:01. The helper epitope also contained three distinct Survivin-killer epitopes presented to HLA-A*02:01 and A*24:02. This 19 amino-acids epitope peptide (SU18) induced weak responses of Survivin-specific CD4(+) and CD8(+) T cells though it contained both helper and killer epitopes. To enhance the vaccine efficacy, we synthesized a long peptide by conjugating SU18 peptide and another DR53-restricted helper epitope peptide (SU22; 12 amino-acids) using glycine-linker. We designated this artificial 40 amino-acids long peptide containing two helper and three killer epitopes as Survivin-helper/killer-hybrid epitope long peptide (Survivin-H/K-HELP). Survivin-H/K-HELP allowed superior activation of IFN-γ-producing CD4(+) Th1 cells and CD8(+) Tc1 cells compared with the mixture of its component peptides (SU18 and SU22) in the presence of OK-432-treated monocyte-derived DC (Mo-DC). Survivin-H/K-HELP-pulsed Mo-DC pretreated with OK-432 also exhibited sustained antigen-presentation capability of stimulating Survivin-specific Th1 cells compared with Mo-DC pulsed with a mixture of SU18 and SU22 short peptides. Moreover, we demonstrated that Survivin-H/K-HELP induced a complete response in a breast cancer patient with the induction of cellular and humoral immune responses. Thus, we believe that an artificially synthesized Survivin-H/K-HELP will become an innovative cancer vaccine.

Abstract
Covalent histone modifications clearly play an essential role in ligand-dependent transcriptional regulation by nuclear receptors. One of the predominant mechanisms used by nuclear receptors to activate or repress target-gene transcription is the recruitment of coregulatory factors capable of covalently modify the amino terminal ends of histones. Here we show that the thyroid hormone (T3) produces a rapid increase in histone H3Ser10 phosphorylation (H3Ser10ph) concomitant to the rapid displacement of the heterochromatin protein 1β (HP1β) to the nuclear periphery. Moreover, we found that T3-mediated pituitary gene transcription is associated with an increase in H3Ser10ph. Interestingly, the Aurora kinase B inhibitor ZM443979 abolishes the effect of T3 on H3Ser10ph, blocks HP1β delocalization, and significantly reduces ligand-dependent transactivation. Similar effects were shown when Aurora kinase B expression was abrogated in small interfering RNA assays. In an effort to understand the underlying mechanism by which T3 increases H3Ser10ph, we demonstrate that liganded thyroid hormone receptor directly interacts with Aurora kinase B, increasing its kinase activity. Moreover, using chromatin immunoprecipitation assays, we have shown that Aurora kinase B participates of a mechanism that displaces HP1β from promoter region, thus preparing the chromatin for the transcriptional activation of T3 regulated genes. Our findings reveal a novel role for Aurora kinase B during transcriptional initiation in GO/G1, apart from its well-known mitotic activity.

Abstract
PURPOSE LY2181308 is an antisense oligonucleotide that complementarily binds to survivin mRNA and inhibits its expression in tumor tissue. This phase I dose escalation study evaluated the tolerability, pharmacokinetics, and anticancer activity of LY2181308 in Japanese. METHODS Patients with solid tumors refractory to standard therapy received LY2181308 (400, 600, or 750 mg) as a 3-h intravenous infusion for 3 consecutive days and thereafter once a week. RESULTS LY2181308 was administered to 14 patients, aged 44-73 (median 60) years. Flu-like syndrome, prolonged prothrombin time-international normalized ratio (PT-INR), thrombocytopenia, and fatigue were common reversible grade 1/2 toxicities. The dose-limiting toxicity was reversible grade 3 elevation of ALT/AST/γ-GTP in 1 patient treated at the 750-mg dose. Pharmacokinetic analysis showed a long terminal half-life of 21 days and an extensive tissue distribution of LY2181308. In 12 evaluable patients, one patient had stable disease, while the remaining 11 patients had progressive disease. CONCLUSIONS LY2181308 monotherapy is well tolerated up to 750 mg with a manageable toxicity, the pharmacokinetic profile warrants further evaluation of LY2181308 in combination with cytotoxic agents or radiotherapy.

Abstract
BACKGROUND Biliary tract cancers have limitations in information about different location-related pathogenesis and clinico-pathological characteristics. The goal of this study was to investigate anatomical site-related similarities and differences in biliary tract cancers and to assess the expression and clinical significance of functional proteins such as p53, cyclin D1, survivin, thymidine phosphorylase, and ERCC1. METHODS One hundred and sixty-one patients with biliary tract adenocarcinomas, who underwent curative or palliative surgery in a single institution between October 1994 and December 2003 were evaluated, retrospectively. The level of protein expression of p53, cyclin D1, survivin, thymidine phosphorylase, and ERCC1 was assessed by immunohistochemistry. RESULTS With respect to clinico-pathological characteristics, gallbladder cancer was more frequent in women, and bile duct cancer was more common in men. Perineural invasion was more common in bile duct cancer. Recurrence as a distant metastasis was more common in gallbladder cancer. Immunohistochemical analysis revealed that thymidine phosphorylase expression was significantly higher in gallbladder cancer than in bile duct cancer. Positive thymidine phosphorylase and p53 staining were associated with an advanced stage. Differentiation, vascular invasion, perineural invasion, lymphatic invasion, lymph node metastasis, and TNM stage independently predicted poor prognosis in biliary tract cancer. These correlations were seen more clearly in gallbladder cancer. The immunohistochemical staining patterns of p53, cyclin D1, survivin, thymidine phosphorylase, and ERCC1 showed no prognostic significance in biliary tract cancers. CONCLUSIONS We concluded that gallbladder and bile duct cancers are considered to be separate diseases with different clinico-pathological characteristics and prognostic factors. In addition, we hypothesize that high expression of thymidine phosphorylase by gallbladder cancer results in a higher response rate to capecitabine by gallbladder cancer than bile duct cancer.

Abstract
Background To investigate the significance of Aurora B expression in hepatocellular carcinoma (HCC). Methods The Aurora B and Aurora A mRNA level was measured in 160 HCCs and the paired nontumorous liver tissues by reverse transcription-polymerase chain reaction. Mutations of the p53 and β-catenin genes were analyzed in 134 and 150 tumors, respectively, by direct sequencing of exon 2 to exon 11 of p53 and exon 3 of β-catenin. Anticancer effects of AZD1152-HQPA, an Aurora B kinase selective inhibitor, were examined in Huh-7 and Hep3B cell lines. Results Aurora B was overexpressed in 98 (61%) of 160 HCCs and in all 7 HCC cell lines examined. The overexpression of Aurora B was associated with Aurora A overexpression (P = 0.0003) and p53 mutation (P = 0.002) and was inversely associated with β-catenin mutation (P = 0.002). Aurora B overexpression correlated with worse clinicopathologic characteristics. Multivariate analysis confirmed that Aurora B overexpression was an independent poor prognostic factor, despite its interaction with Aurora A overexpression and mutations of p53 and β-catenin. In Huh-7 and Hep3B cells, AZD1152-HQPA induced proliferation blockade, histone H3 (Ser10) dephosphorylation, cell cycle disturbance, and apoptosis. Conclusion Aurora B overexpression is an independent molecular marker predicting tumor invasiveness and poor prognosis of HCC. Aurora B kinase selective inhibitors are potential therapeutic agents for HCC treatment.

Abstract
The aim of this study to determine whether serum p53 protein and antibodies are associated with malignant tumors. A case-control study was conduct in 569 patients with various types of malignant tumors and 879 healthy controls. Serum p53 protein and antibodies were analyzed by enzyme-linked immunosorbent assay (ELISA).The rate of positive p53 protein in patients with various malignant tumors was 4.22% compared with 0.34% in healthy controls (P < 0.001). The rate of anti-p53 antibodies in patients with various malignant tumors was 14.59% compared with 1.02% in healthy controls (P < 0.001). The adjusted odd ratio (OR) for p53 protein was 17.55 (95% CI = 4.98-61.94). The adjusted odd ratio for anti-p53 antibodies was 14.27 (95% CI = 6.75-30.16). The study strongly suggested that serum p53 protein and antibody are associated with increased cancer risk and can be used as early serological markers in the diagnosis of malignancies tumors.
