BACKGROUND AND AIMS: BCL2L10 is an apoptosis-related member of the BCL-2 protein family. The role of BCL2L10 in the pathogenesis of hepatocellular carcinoma (HCC) is poorly understood. This study was aimed to investigate the function and underlying mechanisms of BCL2L10 in HCC. METHODS: BCL2L10 expression in human HCC and corresponding adjacent normal tissues was investigated by quantitative real-time PCR and western blot. The biological functions of BCL2L10 in HCC cell lines were determined by cell viability, colony formation, cell apoptosis, cell cycle and cell metastasis assays, and in vivo by tumorigenicity and lung metastasis assays in nude mice...

: Sorafenib is the only chemotherapeutic approved for treatment of advanced hepatocellular carcinoma (HCC.) However, its effectiveness in patients with Child Pugh B cirrhosis and any moderating effects of health system characteristics are unclear. We aimed to examine the survival and cost-effectiveness associated with sorafenib in elderly patients with advanced HCC. We performed an analysis of Medicare beneficiaries with HCC diagnoses from 2007-2009. We compared advanced stage patients with HCC (AJCC stage III/IV) who received sorafenib within 6 months of diagnosis (and were otherwise untreated) to advanced stage patients with HCC who received no therapy (control...

BACKGROUND: The RND1 gene encodes a protein that belongs to the Rho GTPase family, which regulates various cellular functions. Depletion of RND1 expression activates the oncogenic Ras signaling pathway. In this study, we aimed to clarify the clinical significance of RND1 expression in predicting prognosis and to investigate its biological role in human hepatocellular carcinoma (HCC). METHODS: The association between RND1 expression and clinical outcomes in patients with HCC was analyzed in three independent cohorts: 120 cases resected in our hospital; 370 cases in The Cancer Genome Atlas (TCGA); and 242 cases in GSE14520...

BACKGROUND: Hepatocellular carcinoma (HCC) has very high prevalence and associated-mortality. However, targeted therapies that are currently used in clinical practice for HCC have certain limitations, in part because of the lack of reliable and clinically applicable biomarkers that can be used for diagnosis and prognosis assessments and for the surveillance of treatment effectiveness. METHODS: Meta-analysis was used to analyze the integrated microarray data for global identification of a set of robust biomarkers for HCC...

Marital status has been reported as an independent prognostic factor for survival in various cancers, but it has been rarely studied in hepatocellular carcinoma (HCC) treated by surgical resection. We retrospectively investigated Surveillance, Epidemiology, and End Results (SEER) population-based data and identified 13,408 cases of HCC with surgical treatment between 1998 and 2013. The patients were categorized according to marital status, as "married," "never married," "widowed," or "divorced/separated." The 5-year HCC cause-specific survival (HCSS) data were obtained, and Kaplan-Meier methods and multivariate Cox regression models were used to ascertain whether marital status is also an independent prognostic factor for survival in HCC...

To investigate the potential oncogene promoting recurrence of hepatocellular carcinoma (HCC) following liver transplantation (LT), throughput RNA sequencing was performed in a subgroup of HCC patients. The up-regulated FAM83D in HCC tissues was found and further verified in 150 patients by real-time PCR and immunohistochemistry. FAM83D overexpression significantly correlated with high HCC recurrence rate following LT and poor HCC characteristics such as high AFP, poor differentiation. Of cancer stem cells (CSCs) markers, CD44 expression was effectively suppressed when FAM83D was knocked down by siRNA...

Emerging evidence confirms that insulin-like growth factor -II (IGF-II), oncogenes C-myc and N-ras are an essential regulator for development and growth in hepatocellular carcinoma (HCC). Although our previous study also indicated that IGF-II might upregulate levels of oncogenes C-myc and N-ras in hepatoma carcinoma cells, the molecular mechanism had not been fully elucidated. Herein, we successfully silenced IGF-II expression in SMCC-7721 cells by small RNA interference. Functional analysis showed that knockdown of IGF-II significantly suppressed growth and proliferation of SMMC-7721 cells and decreased C-myc and N-ras mRNA and protein levels...

We previously showed that hepatitis B virus (HBV) X protein (HBx) could promote the trimethylation of histone H3 lysine 9 (H3K9me3) to repress tumor suppressor genes in hepatocellular carcinoma (HCC). In this work, we analyze 23,148 human promoters using ChIP-chip to determine the effects of HBx on H3K9me3 enrichments in hepatoma cells with transfection of HBx-expressing plasmid. Immunohistochemistry for HBx and H3K9me3 was performed in 21 cases of HBV-associated HCC tissues. We identified that H3K9me3 immunoreactivity was significantly correlated with HBx staining in HCC tissues...

Hepatocellular carcinoma (HCC) is an aggressive malignancy and the second leading cause of cancer death worldwide. Most current therapeutic agents lack the tumor-targeting efficiency and result in a nonselective biodistribution in the body. In our previous study, we identified a peptide Ala-Pro-Asp-Thr-Lys-Thr-Gln (APDTKTQ) that can selectively bind to the receptor of advanced glycation end-products (RAGE), an immunoglobulin superfamily cell surface molecule overexpressed during HCC malignant progression. Here, we report the design of a mixed micelles system modified with this peptide to target HCC cells...

Monoacylglycerol lipase (MAGL) is a key enzyme in lipid metabolism that is demonstrated to be involved in tumor progression through both energy supply of fatty acid (FA) oxidation and enhancing cancer cell malignance. The aim of this study was to investigate whether MAGL could be a potential therapeutic target and prognostic indicator for hepatocellular carcinoma (HCC). To evaluate the relationship between MAGL levels and clinical characteristics, a tissue microarray (TMA) of 353 human HCC samples was performed...

Lung cancer is the most common solid tumor and the leading cause of cancer-related death worldwide. Non-small cell lung cancer (NSCLC) represents the major histological subtype and accounts for about 80 % cases of lung cancer cases. Recently, lncRNA lncTCF7 was identified, which is highly expressed in hepatocellular carcinoma (HCC) tumors and liver cancer stem cells (CSCs). However, the role of lnTCF7 in NSCLC remains largely unknown. In this study, Gain- and loss-of-function studies demonstrated the critical role of lncTCF7 in promoting invasion and self-renewal in NSCLC cells...

Hepatocellular carcinoma is a lethal cancer with high recurrence ratio and lacks effective therapeutics. In the past few years, it has been reported that increased intake of vegetables and fruits could reduce the cancer incidence, which suggests dietary agents might possess anticancer effects. Eriocitrin is a flavonoid isolated from lemon, which is known as a strong antioxidant agent. We here for the first time demonstrated that eriocitrin could inhibit the proliferation of hepatocellular carcinoma cell lines by arresting cell cycle in S phase through up-regulation of p53, cyclin A, cyclin D3 and CDK6...

EGFR is a promising cell surface target for in vivo imaging that is highly overexpressed in hepatocellular carcinoma (HCC), a common cancer worldwide. Peptides penetrate easily into tumors for deep imaging, and clear rapidly from the circulation to minimize background. We aim to demonstrate use of an EGFR specific peptide to detect HCC xenograft tumors in mice with photoacoustic imaging. Nude mice implanted with human HCC cells that overexpress EGFR were injected intravenously with Cy5.5-labeled EGFR and scrambled control peptides respectively...

The Hippo pathway regulates the down-stream target Yes-associated protein (YAP) to maintain organ homeostasis, which is commonly inactivated in many types of cancers. However, how cell adhesion dysregulates the Hippo pathway activating YAP oncogene in hepatocellular carcinoma (HCC) remains unclear. Our findings demonstrate that α2β1 integrin (but not other β1 integrins) expressed in HCC cells, after binding to collagen extracellular matrix, could inhibit MST1 kinase phosphorylation and activate YAP pro-oncogenic activities...

Increasing evidence(s) have indicated that epithelial to mesenchymal transition (EMT) at the advanced stage of liver cancer, not only has the ability to self-renew and progress cancer, but also enables greater resistance to conventional chemo- and radio-therapies. Here, we report that ascochlorin (ASC), an isoprenoid antibiotic could potentiate the cytotoxic effect of doxorubicin (DOX) on HCCLM3, SNU387, SNU49, and SK-Hep-1 hepatocellular carcinoma (HCC) cells, which had a predominantly mesenchymal signature with low expression of E-cadherin but high expression of N-cadherin...

The oncoprotein Yes-associated protein (YAP) in Hippo pathway plays crucial roles in the development of cancer. However, the mechanism of YAP regulation in cancer remains poorly understood. Here, we supposed that the oncoprotein hepatitis B X-interacting protein (HBXIP) might be involved in the modulation of YAP in liver cancer. Interestingly, our data showed that the expression levels of HBXIP were positively associated with those of YAP in clinical hepatocellular carcinoma (HCC) samples by immunohistochemistry (IHC) staining and real-time PCR assays...
