  • [Show abstract] [Hide abstract] ABSTRACT: Molecular pathogenesis of intrahepatic cholangiocarcinoma (iCCA) is poorly understood and its incidence continues to increase worldwide. Deficiency of MAPK kinase kinase 4 (MAP3K4) has been reported to induce epithelial-mesenchymal transition (EMT) process of placental and embryonic development, yet its role in human cancer remains unknown. Previously, we have found that MAP3K4 had somatic mutation in iCCA. Here, we sequenced all exons of MAP3K4 in 124 iCCA patients and identified 9 somatic mutations in 10 (8.06%) patients, especially in those with lymph node metastasis and intrahepatic metastasis. We also showed that mRNA and protein levels of MAP3K4 were significantly reduced in iCCA than paired nontumor tissues. Furthermore, knockdown of MAP3K4 in cholangiocarcinoma cells markedly enhanced cell proliferation and invasiveness in vitro and tumor progression in vivo, accompanied by a typical EMT process. In contrast, over-expression of MAP3K4 in cholangiocarcinoma cells obviously reversed EMT and inhibited cell invasion. Mechanistically, MAP3K4 functioned as a negative regulator of EMT in iCCA by antagonizing the activity of p38/NF-κB/snail pathway. We found that tumor-inhibitory effect of MAP3K4 was abolished by inactivating mutations. Clinically, a tissue microarray study containing 322 iCCA samples from patients revealed that low MAP3K4 expression in iCCA positively correlated with aggressive tumor characteristics, such as vascular invasion and intrahepatic or lymph node metastases, and was independently associated with poor survival and increased recurrence after curative surgery. MAP3K4, significantly down-regulated, frequently mutated and potently regulating EMT process in iCCA, was a putative tumor suppressor of iCCA. This article is protected by copyright.

Although some researchers have investigated the function of Caveolin-1 in hepatocellular carcinoma, the mechanism of Caveolin-1 action and its prognostic value in hepatocellular carcinoma remain unclear. Caveolin-1 expression was measured in hepatocellular carcinoma cell lines and tissues using quantitative reverse transcription-polymerase chain reaction, western blot, and immunofluorescence assays. In in vitro experiments, Caveolin-1 was depleted using a short hairpin RNA lentiviral vector, and tumor cell behavior was analyzed. The effect of Caveolin-1 on hepatocellular carcinoma cell autophagy was investigated. Prognostic value of Caveolin-1 was analyzed by immunohistochemistry in two cohorts that included a total of 721 hepatocellular carcinoma patients. We found that Caveolin-1 was overexpressed in highly metastatic hepatocellular carcinoma cell lines and tumor tissues. Moreover, Caveolin-1 promoted hepatocellular carcinoma cell proliferation, migration, and angiogenesis and inhibited autophagy. Finally, Caveolin-1 expression in hepatocellular carcinoma tissues was inversely correlated with patient overall survival and time to recurrence. Our data obtained from cell lines suggest an oncogenic role for Caveolin-1 in hepatocellular carcinoma, Caveolin-1 contributed to hepatocellular carcinoma cell autophagy deficiency. Furthermore, Caveolin-1 may function as a novel prognostic indicator for hepatocellular carcinoma patients after curative resection, and combination of targeted therapy aimed at Caveolin-1 and autophagy modulation may represent an effective way to treat hepatocellular carcinoma.

    [Show abstract] [Hide abstract] ABSTRACT: While accumulating evidence has shown that the use of the diabetic drug metformin may be beneficial against various tumors in some epidemiological studies, a few studies failed to show the same beneficial effects. The molecular and cellular mechanisms for these conflicting observations are not clear. In this study, we compared the inhibitory effects of cell growth by metformin on several hepatic tumor cell lines: SMMC-7721, HCC-97L, HCC-LM3 and HepG2. While metformin inhibited cell growth in all these cells, we found that SMMC-7721, HCC-97L and HCC-LM3 cells were more resistant than HepG2 cells. Mechanistically, we found that metformin inhibited mTOR in all these hepatic tumor cells. However, SMMC-7721 cells had higher levels of basal autophagy and mTORC2-mediated feedback activation of Akt than HepG2 cells, which may render SMMC-7721 cells to be more resistant to metformin-induced inhibition of cell growth. Similarly, HCC-97L and HCC-LM3 cells also had higher feedback activation of AKT than HepG2 cells, which may also account for their resistance to metformin-induced inhibition of cell growth. Therefore, the various basal autophagy and mTOR activity in different cancer cells may contribute to the controversial findings on the use of metformin in inhibition of cancers in humans.

  • [Show abstract] [Hide abstract] ABSTRACT: A high preoperative peripheral blood neutrophil-to-lymphocyte ratio (NLR) has been reported to be a predictor of poor survival in patients with various cancers. The aim of this study was to evaluate the predictive significance of the NLR in patients undergoing hepatectomy for intrahepatic cholangiocarcinoma (ICC). From 2005 to 2011, 322 patients who underwent hepatectomy for ICC were enrolled in this retrospective study. Clinicopathological parameters, including NLR, were evaluated to identify predictors of overall and recurrence-free survival after hepatectomy. The best cutoff for NLR was 2.49, and 177 of 322 patients (54.9 %) had an NLR ≥ 2.49. The 5-year survival rate after hepatectomy was 51.1 % in patients with NLR < 2.49 and 24.8 % in those with NLR ≥ 2.49 (P = 0.0001). Univariate analyses revealed that NLR was significantly associated with recurrence-free survival (RFS) and overall survival (OS; both P < 0.05). Multivariable analyses revealed that elevated NLR independently predicted poorer OS (P = 0.003, hazard ratio [HR] = 1.600). In summary, our results indicate that elevated NLR is a promising independent predictor of poor survival after hepatectomy in patients with ICC.

    [Show abstract] [Hide abstract] ABSTRACT: Pyruvate kinase M2 (PKM2) is a member of the pyruvate kinase family. Recent work has defined the "non-metabolic" functions of PKM2. However, the role of PKM2 in HCC remains unclear. To investigate the role of PKM2 in tumor growth, invasion and the prognosis of hepatocellular carcinoma (HCC), PKM2 expression was measured in HCC cell lines and tissues using qRT-PCR, western blot, and immunofluorescence assays. In in vitro experiments, PKM2 was knocked down using a short hairpin RNA lentivirus vector, and tumor cell behavior and the downstream signaling pathways and chemokine were analyzed. For the analysis of in vivo tumor growth, intratumoral and peritumoral lymphocyte infiltration were examined in nude mice. The prognostic value of PKM2 was analyzed by immunohistochemistry in two cohorts including 721 HCC patients. Together, our data obtained from cell lines, tumorigenicity studies, and primary HCC samples illustrate an oncogenic role for PKM2 in tumors. Moreover, PKM2 may serve as a novel prognostic indicator for HCC patients after curative resection, targeted therapy aimed at PKM2 may represent an effective treatment approach for HCC.

  • [Show abstract] [Hide abstract] ABSTRACT: Purpose: Recurrence is a disastrous outcome in patients with hepatitis-related hepatocellular carcinoma (HCC) who have undergone curative resection, and little is known about whether high levels of hepatitis B surface antigen (HBsAg) increase the risk of HCC recurrence. Patients and methods: This retrospective study included 1,360 HBsAg-positive postoperative HCC patients with hepatitis B viral (HBV) DNA levels < 2000 IU/mL, including 298 patients in a training cohort and 1,062 patients in a validation cohort. The prognostic value of the HBsAg level was evaluated using Cox regression and Kaplan-Meier analyses. Results: We demonstrated that 1,000 IU/mL, but not 10 or 100 IU/mL, was a meaningful cutoff level for significantly discriminating these patients into an HBsAg(Low) group and an HBsAg(High) group based on correlations between the HBsAg level and liver cirrhosis (p = 0.028), tumor size (p = 0.039), and hepatitis B e antigen level (p < 0.001). The postoperative 1-, 3-, and 5-year overall survival (OS) rates of HCC patients in the HBsAg(Low) group were significantly higher than those of HCC patients in the HBsAg(High) group. Accordingly, the 5-year recurrence-free survival (RFS) rates of patients in the HBsAg(Low) group were markedly higher than those of HCC patients in the HBsAg(High) group. The HBsAg level was a prognostic indicator for OS (p = 0.014) and RFS (p = 0.01). Conclusion: HBsAg level is correlated with more aggressive tumor behavior and serves as a prognostic indicator in patients with surgically resected HCC with low HBV load.

    [Show abstract] [Hide abstract] ABSTRACT: Background & Aims Pathogenesis of intrahepatic cholangiocarcinoma (ICC), the second-most common hepatic cancer, is a poorly understood and its incidence is increasing worldwide. We searched for mutations in human ICC tumor samples and investigated how they affect ICC cell function. Methods We performed whole-exome sequencing of 7 paired ICCs and their surrounding, non-tumor tissues to detect somatic alterations. We then screened 124 pairs of ICC and non-tumor samples for these mutations, including 7 exomes. We compared mutations in PTPN3 with tumor recurrence in 124 patients, and PTPN3 expression levels with recurrence in 322 patients (the combination of both in 86 patients). The functional effects of PTPN3 variations were determined by RNA interference and transgenic expression in cholangiocarcinoma cell lines (RBE, HCCC-9810, and Huh28). Results Based on exome sequencing, pathways that regulate protein phosphorylation were among the most frequently altered in ICC samples, and genes encoding protein tyrosine phosphatases (PTPs) were among the most frequently mutated. We identified mutations in 9 genes encoding PTPs in 4/7 ICC exomes. In the prevalence screen of 124 paired samples, 51.6% of ICCs contained somatic mutations in at least 1/9 PTP genes; 41.1% had mutations in PTPN3.Transgenic expression of PTPN3 in cell lines increased cell proliferation, colony formation, and migration. PTPN3L232R and PTPN3L384H, which were frequently detected in ICC samples, were found to be gain-of-function mutations; their expression in cell lines further increased cell proliferation, colony formation, and migration. ICC-associated variants of PTPN3 had altered phosphatase activity. Patients whose tumors contained activating mutations or higher levels of PTPN3 protein than non-tumor tissues had higher rates of disease recurrence than patients without. Conclusions Using whole-exome sequencing of ICC samples from patients, we found that more than 40% contain somatic mutations in PTPN3. Activating mutations in and high expression levels of PTPN3 were associated with tumor recurrence in patients.

    [Show abstract] [Hide abstract] ABSTRACT: The expression of 5-hydroxymethylcytosine (5-hmC) and isocitrate dehydrogenase 2 (IDH2) is frequently downregulated in numerous cancers. 5-hmC and IDH2 expression in hepatocellular carcinoma (HCC) has yet to be determined. The immunohistochemical expression of 5-hmC and IDH2 were analyzed in tissue microarrays containing samples from 646 patients who had undergone hepatectomy for histologically proven HCC. The prognostic value of 5-hmC and IDH2 were evaluated by Cox regression and Kaplan-Meier analyses. We discovered that low 5-hmC and IDH2 expression was associated with malignant behaviors. Low 5-hmC or IDH2 expression alone and combined 5-hmC and IDH2 expression were associated with lower overall survival (OS) rates and higher cumulative recurrence rates. Multivariate analysis indicated that 5-hmC or IDH2 and 5-hmC/IDH2 were independent prognostic indicators for OS and time to recurrence (TTR), which was confirmed in an independent validation cohort. 5-hmC and IDH2 correlate with less aggressive tumor behavior in HCC. When 5-hmC and IDH2 are considered together, they serve as a prognostic marker in patients with surgically resected HCCs.

    [Show abstract] [Hide abstract] ABSTRACT: Expression of heterogeneous nuclear ribonucleoprotein AB (hnRNPAB) has been reported to be dysregulated in tumors but its specific contributions to tumor formation and progression are not fully understood. Here, we demonstrate that hnRNPAB is overexpressed in highly metastatic cells and tumor tissues from hepatocellular carcinoma (HCC) patients with recurrence. We found that hnRNPAB overexpression promoted epithelial-mesenchymal transition (EMT) in a manner associated with HCC metastasis in vitro and in vivo. RNAi-mediated silencing of the EMT factor Snail attenuated hnRNPAB-enhanced cell invasion in vitro and lung metastasis in vivo. Mechanistically, HnRNPAB acted to transactivate Snail transcription, which in turn inhibited transcription of the pivotal Snail target gene E-cadherin. Overexpression of hnRNPAB in HCC samples correlated with higher Snail levels, shorter overall survival and higher tumor recurrence. HnRNPAB overexpression, alone or in combination with Snail, was found to be a significant independent risk factor for recurrence and survival after curative resection. In conclusion, our findings define hnRNPAB as an activator of EMT and metastasis in HCC that predicts poor clinical outcomes.

  • [Show abstract] [Hide abstract] ABSTRACT: Hepatocellular carcinoma (HCC) is one of the most serious health problems worldwide. As in many other diseases, environment and genetic factors are believed to be involved in the pathogenesis of HCC. Numerous epidemiologic investigations including case–control and cohort studies have suggested the association of glutathione S-transferase (GST) genetic polymorphisms and HCC risk. However, some studies have produced conflicting results. Therefore, we performed an updated meta-analysis to clarify this inconsistency and to establish a comprehensive picture of the association of the polymorphisms of GSTM1 and GSTT1 with HCC susceptibility. We searched PubMed, Embase, ISI Web of Science, and CNKI databases to identify eligible studies meeting the inclusion criteria up to August 30, 2013. Odds ratios (ORs) and 95 % confidence intervals (CIs) were used to assess the strength of association. Finally, there were a total of 33 studies with 4,232 cases and 6,601 controls included in this meta-analysis. In the pooled analysis, significantly increased HCC risks were found for null genotype of GSTM1 (OR = 1.31, 95 % CI = 1.07–1.61, P = 0.010, P heterogeneity < 10−5) and GSTT1 (OR = 1.47, 95 % CI = 1.25–1.74, P < 10−5, P heterogeneity < 10−5). Potential sources of heterogeneity were explored by subgroup analysis based on ethnicity, sample size, and source of control. Significant results were found among East Asians and Indians when stratified by ethnicity, while no evidence of significant associations was observed among Caucasian and African populations. In the gene–gene interaction analysis, a statistically significant increased risk for HCC was detected for individuals with combined deletion mutations in both genes compared to those with wild genotypes (OR = 1.88, 95 % CI = 1.41–2.50, P < 10−4, P heterogeneity = 0.004). The present meta-analysis demonstrated that the GSTM1 and GSTT1 null genotype may be associated with an increased risk of HCC and that individuals having the combination of both defective GST genotypes may be more susceptible to developing HCC.

  • [Show abstract] [Hide abstract] ABSTRACT: CXCL5 is a member of the CXC-type chemokine family that may play a role in carcinogenesis and cancer progression. This study investigates the biological function and clinical significance of CXCL5 in intrahepatic cholangiocarcinoma (ICC). We demonstrated that CXCL5 was overexpressed in ICC cell lines and tumour samples compared with paired normal tissues. CXCL5 had a direct chemoattractant effect on neutrophils in vitro through PI3K-Akt and ERK1/2 signalling pathways. In animal studies, CXCL5 promoted tumour growth and metastasis without altering in vitro proliferative and invasive ability of ICC cells, and this effect was mediated by the recruitment of intratumoural infiltrative neutrophils by tumour-derived CXCL5. Immunohistochemical analysis of ICC samples showed that overexpression of CXCL5 correlated strongly with intratumoural neutrophil infiltration, shorter overall survival, and high tumour recurrence. Multivariate analysis revealed that CXCL5 overexpression alone, or combined with the presence of intratumoural neutrophils, was an independent prognostic indicator for ICC. In conclusion, our data showed that CXCL5 promotes ICC growth and metastasis by recruiting intratumoural neutrophils. CXCL5 alone or combined with intratumoural neutrophils is a novel prognostic predictor for ICC patients and a potential therapeutic target.

  • [Show abstract] [Hide abstract] ABSTRACT: Metastasis is one of the main causes of poor prognosis for hepatocellular carcinoma (HCC), which has been linked to cell-death resistance. Autophagy is an important survival mechanism under conditions of cell stress. We hypothesized that autophagy may play a role in HCC metastasis due to its prosurvival effect. Highly metastatic HCC cell lines with stable autophagy inhibition were established via lentivirus-mediated silencing of BECN1 and ATG5 genes. Mouse models of pulmonary metastasis were then developed using the cells with or without autophagy inhibition. The analysis of lung metastasis by histopathological examination and small animal imaging showed that autophagy inhibition significantly decreased the incidence of pulmonary metastases in vivo. Further invasion, migration, detachment, lung colonization, and epithelial-mesenchymal transition (EMT) assays indicated that autophagy inhibition did not affect cell invasiveness, migration or EMT but attenuated the anoikis-resistance and lung colonization of HCC cells. Investigation of the molecular mechanisms underlying showed that the autophagy-inhibition-mediated anoikis-resistance attenuation was associated with the regulation of apoptotic signaling. As autophagy inhibition was shown to be able to suppress HCC metastasis, an autophagy-based HCC tissue-specific target therapy system (AFP-Cre/LoxP-shRNA) was constructed. In vitro and in vivo analyses showed that the system was able to efficiently inhibit autophagy of HCC cells and tissue in a tissue-specific manner. Further in vivo metastasis assay showed that intratumoral administration of the system could significantly suppress lung metastasis. Together, our findings suggest that autophagy may be involved in HCC metastasis through facilitating anoikis resistance and lung colonization of HCC cells. Autophagy-based HCC tissue-specific target therapy may be a new strategy for the management of HCC metastasis.

    [Show abstract] [Hide abstract] ABSTRACT: The role of infiltrating B cells in hepatocellular carcinoma (HCC) has been overlooked for many years. This study is aimed to delineate the distribution, prognostic value and functional status of B cells in human HCC. Immunohistochemistry was used to investigate the distribution and clinical significance of infiltrating CD20+ B cells in a series of 120 HCC patients. The results were further tested in an independent series of 200 HCC patients. The functional status of CD20+ B cells was determined by flow cytometry, immunofluorescence and in vitro co-culture assay. Infiltrating CD20+ B cells were predominantly concentrated in the tumor invasive margin, compared to the peri-tumor and intra-tumor areas. High density of margin infiltrating B cells (MIL-Bs) positively correlated with small tumor size, absence of vascular invasion and increased density of CD8+ T cells (P<0.05). Survival analyses revealed that increased MIL-Bs and their penetration through the tumor capsule were significantly associated with improved overall and recurrence-free survival, and were identified as independent prognosticators for HCC patients (P<0.05). Importantly, the results were further validated in another independent HCC cohort. Moreover, we found that MIL-Bs featured an atypical memory phenotype (IgD-IgG+CD27-CD38-), expressed surface markers characteristic of antigen-presenting cells, possessed tumor-killing potential by producing IFN-γ, IL-12p40, granzyme B, TRAIL, and acted in cooperation with CD8+ T cells. The profile of CD20+ B cells in situ is a new predictor of prognosis for HCC patients and provides a novel target for an optimal immunotherapy against this fatal malignancy.

    [Show abstract] [Hide abstract] ABSTRACT: Autophagy is an important adaptive survival mechanism, which has been postulated to be involved in cancer metastasis. The purpose of this study was to investigate autophagy in metastasis of hepatocellular carcinoma (HCC). Immunohistochemical analysis of autophagic activity in metastatic and paired primary HCC tissues using LC3 as autophagosome marker was performed in samples from 216 HCC patients diagnosed with metastasis (including 158 intravascular, 42 intrabiliary, 8 lymph node, 4 bone and 4 lung metastases). Then a mouse model of pulmonary metastasis was established using a highly metastatic HCC cell line (HCCLM3). Autophagy in pulmonary metastases and paired primary tumors were analyzed by LC3 immunohistochemistry, transmission electron microscopy (TEM) and western blot analysis. Further, mouse model of pulmonary metastasis and in vitro cell migration, invasion and detachment models were established using a stable GFP-LC3-expressing HCCLM3 cell line (HCCLM3-GFP-LC3). Autophagic alterations during metastatic colonization, migration, invasion and detachment were determined by GFP-LC3 analysis and western blot analysis. LC3 immunohistochemistry of metastases and primary tumors from HCC patients revealed significantly higher LC3 expression in metastases than primary HCC, which suggested a higher level of autophagy in HCC metastases. Further immunohistochemical, TEM, western blot and in vivo GFP-LC3 analyses of lung metastases and primary tumors in mouse model of pulmonary metastasis confirmed that metastatic colonies displayed higher level of autophagy than primary tumors and the early metastatic colonies displayed highest level. The dynamic monitoring of autophagy in cell migration, invasion and detachment showed that autophagy did not significantly alter in those processes. Autophagy is activated in metastatic colonization but not in invasion, migration and detachment of HCC cells. Autophagy may play a role in HCC metastasis via promoting metastatic colonization of HCC cells.

  • [Show abstract] [Hide abstract] ABSTRACT: Unlabelled: The overall survival of patients with hepatocellular carcinoma (HCC) remains poor, and the molecular pathogenesis remains incompletely defined in HCC. Here we report that increased expression of αB-Crystallin in human HCC predicts poor survival and disease recurrence after surgery. Multivariate analysis identifies αB-Crystallin expression as an independent predictor for postoperative recurrence and overall survival. We show that elevated expression of αB-Crystallin promotes HCC progression in vivo and in vitro. We demonstrate that αB-Crystallin overexpression fosters HCC progression by inducing epithelial-mesenchymal transition (EMT) in HCC cells through activation of the extracellular-regulated protein kinase (ERK) cascade, which can counteract the effect of sorafenib. αB-Crystallin complexes with and elevates 14-3-3ζ protein, leading to up-regulation of ERK1/2 activity. Moreover, overexpression of αB-Crystallin in HCC cells induces EMT progression through an ERK1/2/Fra-1/slug signaling pathway. Clinically, our data reveal that overexpression of both αB-Crystallin and 14-3-3ζ correlates with the HCC poorest survival outcomes, and sorafenib response is impaired in patients with αB-Crystallin overexpression. Conclusion: These data suggest that the αB-Crystallin-14-3-3ζ complex acts synergistically to promote HCC progression by constitutively activating ERK signaling. This study reveals αB-Crystallin as a potential therapeutic target for HCC and a biomarker for predicting sorafenib treatment response. (HEPATOLOGY 2013).

    [Show abstract] [Hide abstract] ABSTRACT: Background: Frequent deletions of the kinesin-like protein gene 1B (KIF1B) have been reported in neural tumors. Recently, a genome-wide association study revealed an association between polymorphisms in the KIF1B gene and the risk of hepatocellular carcinoma (HCC), and several case-control studies have further investigated this relationship. However, these studies have yielded controversial results. We therefore performed a meta-analysis to derive a more precise estimation of the association between the KIF1B gene polymorphisms and HCC risk. Methodology/principal finding: PubMed, EMBASE, the ISI Web of Science and the CNKI databases were systematically searched to identify relevant studies. A total of 5 studies containing 13 cohorts with 5,773 cases and 6,404 controls were included. Odds ratios (ORs) with corresponding 95% confidence intervals (CIs) were used to assess the strength of the associations. Subgroup analyses were conducted based on ethnicities, sample sizes and quality scores. Overall, the G allele at rs17401966 of the KIF1B gene was associated with a significantly decreased risk for HCC (OR = 0.81, 95%CI: 0.70-0.93; P = 0.003). Furthermore, subgroup analyses showed that the G allele at rs17401966 of the KIF1B gene significantly reduced the risk for HCC in Chinese cohorts (OR = 0.76, 95%CI: 0.64-0.90; P = 0.002), large-sample-size cohorts (OR = 0.80, 95%CI: 0.73-0.88, P<0.01) and high-quality cohorts (OR = 0.78, 95%CI: 0.71-0.87, P<0.01). However, no significant associations were found in small-sample-size cohorts, studies with low-quality scores and when excluding the cohorts from the study reporting the original discovery. Conclusion/significance: These findings demonstrate that the presence of the G allele at rs17401966 of the KIF1B gene may decrease the risk for HCC and suggest that KIF1B may play a critical role in the development of HCC. High-quality studies with larger sample sizes and different ethnic populations will be of great value to further confirm these findings.
