Abstract
OBJECTIVES Hepatocellular carcinoma (HCC) is a primary malignancy of the liver and a global health problem. It is often diagnosed at advanced stage where hopeless for effective therapies. Identification of more reliable biomarkers for early detection of HCC is urgently needed. Cytokeratins are a marker of hepatic progenitor cells and act as a key player in tumor invasion. Herein, we sought to develop a novel score based on the combination of cytokeratin 18 (CK18) and cytokeratin 19 (CK19) with routine laboratory tests for accurate detection of HCC. MATERIAL & METHODS Serum CK18, CK 19, α-fetoprotein, albumin and platelets count were assayed in HCC patients (75), liver cirrhosis patients (55) and healthy control (20). Areas under receiving operating curve (AUCs) were calculated and used for construction on novel score. A novel score named CK-HCC = CK 19 (ng/ml)×0.001+ CK18 (ng/ml)×0.004 + AFP (U/L)×5.4 - Platelets count (×109)/L×0.003 - Albumin (g/L)×0.27-36 was developed. CK-HCC score produces AUC of 0.919 for differentiating patients with HCC from those with liver cirrhosis with sensitivity and specificity of a cut-off 1.3 (i.e., less than 1.3 the case is considered cirrhotic, whereas above 1.3 it is considered HCC. CONCLUSION CK-HCC score could replace AFP during screening of HCV patients and early detection of HCC.

Abstract
Hepatocellular carcinoma (HCC) is an aggressive and challenging disease to treat. Due to the lack of effective early diagnosis and therapy for the illness, it is crucial to identify novel biomarkers that can predict tumor behavior in HCC. In such cases, family with sequence similarity 210 member B (FAM210B) is abundant in various human tissues, but its regulatory mechanisms and role in various tissues remain unclear. In this study, we analyzed the expression pattern of FAM210B in HCC using public gene expression databases and clinical tissue samples. Our results confirmed that FAM210B was dysregulated in both HCC cell lines and HCC paraffin section samples. FAM210B depletion significantly increased the capacity of cells to grow, migrate, and invade in vitro, while overexpression of FAM210B suppressed tumor growth in a xenograft tumor model. Furthermore, we identified FAM210B's involvement in MAPK signaling and p-AKT signaling pathways, both of which are known oncogenic signaling pathways. In summary, our study provides a rational basis for the further investigation of FAM210B as a valuable biological marker for diagnosing and predicting the prognosis of HCC patients.

Abstract
BACKGROUND Curative hepatectomy is currently the first-line treatment for hepatocellular carcinoma (HCC), but the prognosis is still not optimistic. The prediction model for prognosis of hepatitis B virus (HBV)-related BCLC 0-A stage HCC has not been well established. Therefore, we aimed to develop new nomograms to predict recurrence and survival in these patients. METHODS A total of 982 patients with HBV-related BCLC 0-A stage HCC who underwent curative hepatectomy at West China Hospital from February 2007 to February 2016 were retrospectively collected and randomly allocated to a training set and a validation set in a ratio of 4:1. Prognostic nomograms using data from the training set were developed using a Cox regression model and validated on the validation set. RESULTS We constructed nomograms based on independent factors for recurrence-free survival (RFS) (tumor size, satellite, microvascular invasion, capsular invasion, differentiation and aspartate aminotransferase to albumin ratio (ASAR)) and overall survival (OS) (gender, tumor size, satellite, microvascular invasion, differentiation, lymphocyte count, and ASAR). Compared with conventional HCC staging systems and other nomograms reported by previous literature, our ASAR integrated nomograms predicted RFS and OS with the highest C-indexes (0.682 (95%CI: 0.646-0.709), 0.729 (95%CI: 0.691-0.766), respectively) and had well-fitted calibration curves in the training set. Concurrently, the nomograms also obtained consistent results in the validation set. DCA revealed that our nomograms provided the largest clinical net benefits. CONCLUSION We first constructed ASAR integrated nomograms to predict the prognosis of HBV-related BCLC 0-A stage HCC patients after curative hepatectomy with good performance.

Abstract
FYB2 (also known as C1orf168 or ARAP) is an adaptor protein involved in T-cell receptor (TCR)-mediated T-cell activation and adhesion. However, the correlation of FYB2 with prognosis and cancer needs further investigation. In this study, we analyzed the expression levels of FYB2 in hepatocellular carcinoma (LIHC) tumor tissues and correlated it with the pathological stages, survival outcomes, and tumor grades. We found that the expression of FYB2 was significantly downregulated in LIHC. Low FYB2 level leading to weak survival outcomes is linked with advanced tumor grades and elevated pathological stages. Cox regression analysis showed that FYB2 and AJCC-M stages can be used as independent prognostic factors for LIHC. GSEA analysis revealed that FYB2 would be notably correlated with the cellular metabolism-related pathways and particularly involved in the regulation of cancer-related pathways. Single-cell transcriptome analysis revealed that FYB2-positive cells were mainly distributed in hepatocytes, and compared with other cells, the upregulated genes of these cells were mainly enriched in metabolism-related functions. The results of the spatial transcriptome revealed that the expression of FYB2 in the adjacent area was higher than in the tumor area. These results showed that FYB2 is likely to be a new prognostic biomarker in LIHC and would help provide individual treatment decisions for LIHC patients.

The Role of SNHG15 in the Pathogenesis of Hepatocellular Carcinoma. J Pers Med 2022; 12:jpm12050753. [PMID: 35629174 PMCID: PMC9145272 DOI: 10.3390/jpm12050753] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2022] [Revised: 04/18/2022] [Accepted: 05/03/2022] [Indexed: 02/07/2023] Open
Abstract
Long non-coding RNAs (lncRNAs) are transcripts of more than 200 nucleotides which cannot be translated into proteins. Small nucleolar RNA host gene 15 (SNHG15) is a lncRNA whose dysregulation has been found to have an important impact on carcinogenesis and affect the prognosis of cancer patients in various cancer types. Hepatocellular carcinoma (HCC) is one of the most common cancers with a poor long-term prognosis, while the best prognostic factor of the disease is its early diagnosis and surgery. Consequently, the investigation of the mechanisms of hepatocarcinogenesis, as well as the discovery of efficient molecular markers and therapeutic targets are of great significance. An extensive literature search was performed in MEDLINE in order to identify clinical studies that tried to reveal the role of SNHG15 in HCC. We used keywords such as ‘HCC’, ‘hepatocellular carcinoma’, ‘SNHG15’ and ‘clinical study’. Finally, we included four studies written in English, published during the period 2016–2021. It was revealed that SNHG15 is related to the appearance of HCC via different routes and its over-expression affects the overall survival of the patients. More assays are required in order to clarify the potential role of SNHG15 as a prognostic tool and therapeutic target in HCC.

Abstract
Aim of the study AT-rich interactive domain 1A (ARID1A) is a subunit of the switch/sucrose non-fermentable chromatin remodeling complex, which is commonly mutated in human cancers. The clinical and pathological significance of ARID1A alteration in hepatocellular carcinoma (HCC) has not yet been clarified. The present study aimed to evaluate the clinical significance of the ARID1A gene signature in HCC and its relation to the likelihood of tumor recurrence after microwave ablation (MWA). Material and methods This study included 50 patients with cirrhotic HCC of Barcelona Clinic Liver Cancer stages 0/A eligible for MWA. Tumor and peri-tumor biopsies were obtained just prior to MWA and assessed for tumor pathological grade and ARID1A expression by immunohistochemistry. Patients were followed for one year after complete tumor ablation to detect any recurrence. Results Tumor size (MCp = 0.010) and α-fetoprotein level (p = 0.013) can effectively predict the response to MWA. Nuclear expression of ARID1A was significantly lower in HCC compared to the corresponding peri-tumor cirrhotic liver tissues (p = 0.002), but no significant difference in ARID1A cytoplasmic expression was found. Nuclear ARID1A expression level in HCC showed a significantly negative relation to tumor size (MCp = 0.006), pathological grade (MCp = 0.046) and post-MWA tumor recurrence (FEp = 0.041). Conclusions ARID1A loss may enhance HCC aggressiveness and post-MWA tumor recurrence. ARID1A could be a potential target to select HCC patients for future therapies.

Abstract
Hepatocellular carcinoma (HCC) is the most prevalent type of hepatic carcinoma. Long noncoding RNAs (lncRNAs) are considered crucial regulators of gene expression; however, their functions in HCC are not well understood. Thus, the present study is aimed at elucidating the functions of the lncRNA HOXA-AS3 in HCC. The functions of the HOXA-AS3/miR-455-5p/programmed death-ligand 1 (PD-L1) axis were investigated in vitro via qRT-PCR and dual-luciferase reporter assays. The effect of HOXA-AS3 expression on tumor growth and metastasis was assessed using a mouse xenograft model. High HOXA-AS3 expression was observed in the HCC cell lines. Furthermore, overexpression of HOXA-AS3 in HCC cells enhanced proliferation, migration, and invasion, regulated the cell cycle, and retarded apoptosis. We also identified an miR-455-5p binding site in HOXA-AS3. By sponging miR-455-5p, HOXA-AS3 increased the expression of PD-L1. Additionally, both the inhibition of PD-L1 and overexpression of miR-455-5p reversed the effects on cell proliferation and invasion triggered by the overexpression of HOXA-AS3. In conclusion, HOXA-AS3 modulated the functions of HCC cells through the miR-455-5p/PD-L1 axis. Therefore, HOXA-AS3 may be a novel therapeutic target for HCC.

Abstract
Background Hepatocellular carcinoma (HCC) is the sixth most common cancer in the world and the third leading cause of cancer-related death. Although the diagnostic scheme of HCC is currently undergoing refinement, the prognosis of HCC is still not satisfactory. In addition to certain factors, such as tumor size and number and vascular invasion displayed on traditional imaging, some histopathological features and gene expression parameters are also important for the prognosis of HCC patients. However, most parameters are based on postoperative pathological examinations, which cannot help with preoperative decision-making. As a new field, radiomics extracts high-throughput imaging data from different types of images to build models and predict clinical outcomes noninvasively before surgery, rendering it a powerful aid for making personalized treatment decisions preoperatively. Objective This study reviewed the workflow of radiomics and the research progress on magnetic resonance imaging (MRI) radiomics in the diagnosis and treatment of HCC. Methods A literature review was conducted by searching PubMed for search of relevant peer-reviewed articles published from May 2017 to June 2021.The search keywords included HCC, MRI, radiomics, deep learning, artificial intelligence, machine learning, neural network, texture analysis, diagnosis, histopathology, microvascular invasion, surgical resection, radiofrequency, recurrence, relapse, transarterial chemoembolization, targeted therapy, immunotherapy, therapeutic response, and prognosis. Results Radiomics features on MRI can be used as biomarkers to determine the differential diagnosis, histological grade, microvascular invasion status, gene expression status, local and systemic therapeutic responses, and prognosis of HCC patients. Conclusion Radiomics is a promising new imaging method. MRI radiomics has high application value in the diagnosis and treatment of HCC.

Abstract
Purpose: Hepatocellular carcinoma (HCC) is one of the most prevalent malignant diseases worldwide and has a poor prognosis. Gene-based prognostic models have been reported to predict the overall survival of patients with HCC. Unfortunately, most of the genes used in earlier prognostic models lack prospective validation and, thus, cannot be used in clinical practice. Methods: Candidate genes were selected from GEPIA (Gene Expression Profiling Interactive Analysis), and their associations with patients’ survival were confirmed by RT-PCR using cDNA tissue microarrays established from patients with HCC after radical resection. A multivariate Cox proportion model was used to calculate the coefficient of corresponding gene. The expression of seven genes of interest (MKI67, AR, PLG, DNASE1L3, PTTG1, PPP1R1A, and TTR) with two reference genes was defined to calculate a risk score which determined groups of different risks. Results: Our risk scoring efficiently classified patients (n = 129) with HCC into a low-, intermediate-, and high-risk group. The three groups showed meaningful distinction of 3-year overall survival rate, i.e., 88.9, 74.5, and 20.6% for the low-, intermediate-, and high-risk group, respectively. The prognostic prediction model of risk scores was subsequently verified using an independent prospective cohort (n = 77) and showed high accuracy. Conclusion: Our seven-gene signature model performed excellent long-term prediction power and provided crucially guiding therapy for patients who are not a candidate for surgery.

Abstract
ABSTRACT Growing evidence supports that the tumor microenvironment plays a key role in the development and progression of tumors. But immune microenvironment of hepatocellular carcinoma (HCC) has not yet been fully explored. In the present investigation, the clinical value and prognostic significance of immune-related genes in HCC were investigated.The immune and stromal scores of HCC were calculated through the application of Estimation of Stromal and Immune cells in Malignant Tumor tissues using Expression data Algorithm based on the Cancer Genome Atlas database. Differentially expressed genes were identified using the "edgeR" package of the R software. Functional annotation and pathway enrichment were performed using "ggplots2" and "clusterProfiler" packages in R software. Protein-protein interaction network was constructed using STRING, and the hub genes were identified through the Cytoscape. Survival analysis was performed using Kaplan-Meier methods. Tumor Immune Estimation Resource algorithm was used to view the immune landscape of the microenvironment in HCC.Firstly, the immune and stromal scores of HCC were calculated and we found that the immune and stromal scores of HCC were closely related to the patients' prognosis. Then the differentially expressed genes were identified respectively stratified by the median value of the immune and stromal scores, and the immune-related genes that related to the prognosis in HCC patients were further identified. Functional enrichment analysis and protein-protein interaction networks further showed that these genes mainly participated in immune-related biological process. In addition, dendritic cells were found to be the most abundant in the microenvironment of HCC through Tumor Immune Estimation Resource algorithm and were significantly associated with the patients' prognosis. To robust the results, the immune-related genes were validated in an independent dataset from the Gene Expression Omnibus database.We arrived at a more comprehensive understanding of the microenvironment of HCC and extracted 7 immune-related genes that were significantly associated with the recurrence survival of HCC.

Abstract
PURPOSES The purposes of this study were to assess the correlation between the plasma level of Hsp90α and the clinicopathological characteristics of patients with liver cancer and compare the diagnostic efficacy of Hsp90α, AFP, CEA, and CA199 in HCC. EXPERIMENTAL DESIGN A total of 200 individuals, including 140 patients with liver cancer or benign liver diseases and 60 healthy people, were enrolled for quantitative measurement of plasma Hsp90α by ELISA. RESULTS The plasma level of Hsp90α was significantly different between patients with liver cancer or benign liver diseases and healthy controls (P < 0.001). The sensitivity, specificity, and AUC (95% CI) of Hsp90α were 93.2%, 85.4%, and 0.931% (0.891-0.972%), respectively, when Hsp90α was applied to differentiate liver cancer patients and healthy controls. Significant positive correlations between the plasma Hsp90α level and clinicopathological characteristics such as the history of basic liver disease (P = 0.038), active stage of hepatitis (P = 0.039), Child-Pugh score (P < 0.001), size of focal liver lesions (P = 0.004), and extrahepatic metastasis (P < 0.001) were observed. AFP + Hsp90α was the best combination strategy for the auxiliary diagnosis of HCC, with a sensitivity of 95.7%, a specificity of 97.5%, and an AUC of 0.990 (0.976-1.000). The level of plasma Hsp90α decreased significantly (P < 0.001) after resection of tumor tissue. CONCLUSIONS This study demonstrated that plasma Hsp90α levels are useful as a diagnostic biomarker in liver cancer and may predict the responses of patients with liver cancer to surgery. Some clinicopathological characteristics could affect the plasma Hsp90α levels.

Abstract
Aim: Hepatocellular carcinoma (HCC) is considered to be the third leading cause of cancer death. The homologous gene of TP53 is significant in the occurrence and development of cancer. This study explored the relationship between TP53 rs28934571 polymorphism and HCC risk in Guangxi, China. Materials & methods: We first screened the association through bioinformatics. Additionally, a case-control study was performed to further verify the relationship between gene polymorphism and HCC risk after collecting clinical characteristics. Results: Results showed that allele A on TP53 rs28934571 was a risk factor for HCC and mutation from C to A on TP53 rs28934571 would increase the risk of poor prognosis of HCC. Conclusion: Therefore, the study concluded that TP53 rs28934571 may become a diagnostic indicator in judging the prognosis of HCC.

MicroRNA-4651 represses hepatocellular carcinoma cell growth and facilitates apoptosis via targeting FOXP4. Biosci Rep 2021; 40:224903. [PMID: 32436934 PMCID: PMC7286879 DOI: 10.1042/bsr20194011] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2019] [Revised: 04/16/2020] [Accepted: 04/17/2020] [Indexed: 12/24/2022] Open
Abstract
MicroRNAs (miRNAs) belong to the subgroup of small noncoding RNAs, which typically serve as important gene regulators to participate in different biological events, such as tumor cell growth and apoptosis. Recent studies indicated microRNA-4651 (miR-4651) was involved in hepatocellular carcinoma (HCC) progression. The certain role of miRNA-4651 during the progression of HCC, however, remains unclear. Herein, we investigated the mRNA expression level of miR-4651 in HCC tissues and HCC cell lines and found miR-4651 was noticeably down-regulated compared with the normal liver tissues and QSG-7701 cell line, respectively. Then, miR-4561 overexpression obviously repressed the proliferation and promoted apoptosis in two HCC cell lines. Interestingly, we further identified that miR-4561 could directly interact with FOXP4 in HCC cells by using bio-informatic method and report assay. Moreover, forced expression of FOXP4 showed an opposite effect compared with miR-4561 in HCC cell lines. Hence, our findings strongly indicated that miR-4561 regulated the HCC cell growth and apoptosis mainly through targeting the FOXP4 genes. Clinically, the miR-4561/FOXP4 axis might be a potential target for therapeutic application of HCC patient treatment.

Abstract
Transmembrane protein (TMEM) is a kind of integral membrane protein that spans biological membranes. The functions of most members of the TMEM family are unknown. Here, we conducted bioinformatic analysis and biological validation to investigate the role of TMEM106C in HCC. First, GEPIA and OncomineTM were used to analyze TMEM106C expression, which was verified by real-time PCR and western blot analyses. Then, the biological functions of TMEM106C were explored by CCK8 and transwell assays. The prognostic value of TMEM106C was analyzed by UALCAN. LinkedOmics was used to analyze TMEM106C pathways generated by Gene Ontology. A protein-protein interaction network (PPI) was constructed by GeneMANIA. We demonstrated that TMEM106C was overexpressed in HCC and that inhibition of TMEM106C significantly suppressed the proliferation and metastasis of HCC through targeting CENPM and DLC-1. Upregulation of TMEM106C was closely correlated with sex, tumor stage, tumor grade and prognosis. Overexpression of TMEM106C was linked to functional networks involving organelle fission and cell cycle signaling pathways through the regulation of CDK kinases, E2F1 transcription factors and miRNAs. Our data demonstrated that TMEM106C contributes to malignant characteristics and poor prognosis in HCC, which may serve as a prognostic biomarker and potential therapeutic target.

BIOMED RESEARCH INTERNATIONAL 2021; 2021:6685723. [PMID: 33506029 PMCID: PMC7810556 DOI: 10.1155/2021/6685723] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 11/23/2020] [Accepted: 12/23/2020] [Indexed: 12/14/2022]
Abstract
Purpose To investigate whether the radiomics analysis of MR imaging in the hepatobiliary phase (HBP) can be used to predict microvascular invasion (MVI) in patients with hepatocellular carcinoma (HCC). Method A total of 130 patients with HCC, including 80 MVI-positive patients and 50 MVI-negative patients, who underwent MR imaging with Gd-EOB-DTPA were enrolled. Least absolute shrinkage and selection operator (LASSO) regression was applied to select radiomics parameters derived from MR images obtained in the HBP 5 min, 10 min, and 15 min images. The selected features at each phase were adopted into support vector machine (SVM) classifiers to establish models. Multiple comparisons of the AUCs at each phase were performed by the Delong test. The decision curve analysis (DCA) was used to analyze the classification of MVI-positive and MVI-negative patients. Results The most predictive features between MVI-positive and MVI-negative patients included 9, 8, and 14 radiomics parameters on HBP 5 min, 10 min, and 15 min images, respectively. A model incorporating the selected features produced an AUC of 0.685, 0.718, and 0.795 on HBP 5 min, 10 min, and 15 min images, respectively. The predictive model for HBP 5 min, 10 min and 15 min showed no significant difference by the Delong test. DCA indicated that the predictive model for HBP 15 min outperformed the models for HBP 5 min and 10 min. Conclusions Radiomics parameters in the HBP can be used to predict MVI, with the HBP 15 min model having the best differential diagnosis ability.

Abstract
Circular RNAs (circRNAs) have been verified to have essential regulatory roles in diverse human cancers, including hepatocellular carcinoma (HCC). In this study, we aimed to explore the roles of circ_0001445 in HCC. Herein, circ_0001445 was decreased and miR-942-5p was increased in HCC tissues and cells. Circ_0001445 overexpression or miR-942-5p inhibition repressed cell cycle process, migration, invasion, epithelial-mesenchymal transition and glycolysis in HCC cells. Mechanistically, circ_0001445 could promote ALX4 expression through targeting miR-942-5p. Moreover, miR-942-5p overexpression reversed the inhibitory effect of circ_0001445 on HCC cell progression. The effect of miR-942-5p on HCC cell development was rescued following the elevation of ALX4. In addition, circ_0001445 overexpression restrained tumorigenesis in vivo. In conclusion, circ_0001445 played a negative role in HCC progression by modulating miR-942-5p/ALX4 axis, which might provide a novel target for HCC therapy.

Abstract
Tumor cells primarily utilize aerobic glycolysis for energy production, a phenomenon known as the Warburg effect, but the involvement of Warburg effect in liver cancer cell metastasis is not well understood. In present study, our results indicate a positive correlation between glucose metabolism level and metastatic potential of hepatocellular carcinoma (HCC). We also observed that a long noncoding RNA-SOX2OT (lncRNA-SOX2OT) can not only increase the metastatic potential of HCC but also promote a pyruvate kinase M2 (PKM2)-mediated activation of glucose metabolism. Inhibition of PKM2 in HCC cells greatly compromises lncRNA-SOX2OT in promoting Warburg effect and metastasis. Furthermore, miR-122-5p was found being a direct target of lncRNA-SOX2OT in regulating PKM2 expression. Thus, our findings reveal that lncRNA-SOX2OT, a regulator of PKM2, could predispose HCC patients to metastases and may serve as a candidate for metastatic prediction and therapies in HCC patients.

Abstract
BACKGROUND AND STUDY AIMS The risk of hepatocarcinogenesis depends on background liver factors, of which fibrosis is a major determinant. Serum markers and scores are of increasing importance in non-invasive diagnosis of hepatic fibrosis. Our aim was to predict the occurrence of hepatocellular carcinoma (HCC) using a non-invasive fibrosis score calculated using routine patient data. PATIENTS AND MTHODS Our retrospective study included 1,291 hepatitis C related-HCC Egyptian patients (Group 1) recruited from the multidisciplinary HCC clinic, Faculty of Medicine, Cairo University in the period between February 2009 and June 2016 and 1072 chronic hepatitis C-naïve patients (Group 2) with advanced fibrosis (≥F3) and cirrhosis (F4). King score, Fibro Q score, Aspartate aminotransferase-to-platelet ratio index (APRI), AST to ALT ratio (AAR), LOK score, Göteborg University Cirrhosis Index (GUCI), Fibro-α and Biotechnology Research Center (BRC) scores were calculated for all patients. Regression analysis and receiver operating characteristics (ROC) were used to calculate the sensitivity, specificity and predictive values for significant scores with the best cut-off for predicting HCC. A regression equation was used to calculate predicted probabilities of HCC using the following variables; age, gender, haemoglobin, international normalised ratio (INR), albumin and alpha fetoprotein. The appropriate score cut-off points yielding optimal sensitivity and specificity were determined by ROC curve analysis. RESULTS There was a highly significant difference between the two groups for all calculated scores (P = 0.0001). Our new score, the Hepatocellular Carcinoma Multidisciplinary Clinic-Cairo University (HMC-CU) score (Logit probability of HCC = - 2.524 + 0.152*age - 0.121*Hb - 0.696*INR - 1.059*Alb + 0.022*AFP + 0.976*Sex. Male = 1, Female = 0), with a cut-off of 0.559 was superior to other scores for predicting HCC, having a sensitivity of 90% and specificity of 80.6%. CONCLUSION The HMC-CU score is a promising, easily calculated, accurate, cost-effective score for HCC prediction in chronic HCV patients with advanced liver fibrosis.

Abstract
Long non-coding RNA termed GAS6 antisense RNA 1 (GAS6-AS1) plays an essential role in gastric and non-small cell lung cancers. Nonetheless, the function of GAS6-AS1 in hepatocellular carcinoma (HCC) has not been so far studied in detail. In this study, reverse-transcription quantitative PCR was performed to measure GAS6-AS1 expression in HCC samples. A series of functional experiments, including MTT assay, colony formation assay, flow-cytometric analysis, and transwell migration and invasion assays, was performed to determine the influence of GAS6-AS1 knockdown on the malignant phenotype of HCC. The results showed that GAS6-AS1 was significantly upregulated in HCC tissue samples and cell lines. Increased GAS6-AS1 expression was associated with tumor size, Edmondson grade, and Tumor-Node-Metastasis (TNM) stage among patients with HCC. The overall survival of patients with HCC characterized with high expression of GAS6-AS1 was significantly shorter in comparison to that of patients with low level of GAS6-AS1. Functional experiments indicated that knockdown of GAS6-AS1 suppressed HCC cell proliferation, colony formation, migration, and invasion in vitro; promoted apoptosis in vitro; and decreased tumor growth in vivo. Of note, GAS6-AS1 was validated as a competing endogenous RNA (ceRNA) for microRNA-585 (miR-585) and consequently increased the expression of eukaryotic translation initiation factor 5A2 (EIF5A2). Finally, rescue experiments confirmed the association among GAS6-AS1, miR-585, and EIF5A2 in HCC cells. Our study provides substantial evidence that the GAS6-AS1/miR-585/EIF5A2 pathway plays an important role in HCC progression and that might be considered as a potential target for therapeutic approaches in HCC.

Abstract
Background Recurrence is the major cause of mortality in patients with resected HCC. However, without a standard approach to evaluate prognosis, it is difficult to select candidates for additional therapy. Methods A total of 201 patients with HCC who were followed up for at least 5 years after curative hepatectomy were enrolled in this retrospective, multicentre study. A total of 3144 radiomics features were extracted from preoperative MRI. The random forest method was used for radiomics signature building, and five-fold cross-validation was applied. A radiomics model incorporating the radiomics signature and clinical risk factors was developed. Results Patients were divided into survivor (n = 97) and non-survivor (n = 104) groups based on the 5-year survival after surgery. The 30 most survival-related radiomics features were selected for the radiomics signature. Preoperative AFP and AST were integrated into the model as independent clinical risk factors. The model demonstrated good calibration and satisfactory discrimination, with a mean AUC of 0.9804 and 0.7578 in the training and validation sets, respectively. Conclusions This radiomics model is a valid method to predict 5-year survival in patients with HCC and may be used to identify patients for clinical trials of perioperative therapies and for additional surveillance.

Abstract
Liver cancer is one of the most common malignant tumors in the world. Circular RNAs (circRNAs) perform important functions in cancer progression and are regarded as prospective biomarkers for cancer diagnosis and therapy. Here, we used the high-throughput RNA sequencing technology in conjunction with bioinformatics tools to profile circRNA expression in patients with HBV-related liver cancer. A total of 13,124 circRNAs were identified in HBV-related liver cancer, approximately 86.25% of which were sense-overlapping circRNAs. Moreover, 2,996 circRNAs exhibited different expression patterns between liver cancer tissues and matched pericancerous tissues. Function annotation indicated that these aberrantly expressed circRNAs were primarily engaged in cellular processes and cancer-associated pathways. Notably, the circRNA-miRNA interaction networks showed that 6,020 circRNAs were predicted to target 1,654 miRNAs. Quantitative RT-PCR (qRT-PCR) assay indicated that ten randomly selected circRNAs displayed consistent expression patterns with the sequencing results. We further predicted that circRNA_10156 might work as a molecular sponge of miR-149-3p, which served an important function in tumor development. Consequently, our results demonstrated that depletion of circRNA_10156 upregulated miR-149-3p, reduced Akt1 expression, and suppressed liver cancer cell proliferation. The present study will facilitate the elucidation of biological functions of circRNAs in the progression of HBV-related liver cancer providing prospective biomarkers and therapeutic targets for this disease. Our findings also reveal that circRNA_10156 might represent a promising therapeutic target for liver cancer management.

Chen Z, Gao Y, Gao S, Song D, Feng Y. MiR-135b-5p promotes viability, proliferation, migration and invasion of gastric cancer cells by targeting Krüppel-like factor 4 (KLF4). Arch Med Sci 2020; 16:167-176. [PMID: 32051721 PMCID: PMC6963155 DOI: 10.5114/aoms.2019.87761] [Citation(s) in RCA: 23] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2017] [Accepted: 07/23/2017] [Indexed: 12/14/2022] Open
Abstract
INTRODUCTION The expression of MiR-135b-5p was up-regulated while Krüppel-like factor 4 (KLF4) expression was extremely low in human gastric carcinoma (GC) tissues. This study aimed to explore the role of miR-135b-5p in GC cells and its influence on various cell capacity and viability by targeting KLF4. MATERIAL AND METHODS The dual-luciferase reporter assay was first performed and the target relationship between miR-135b-5p and KLF4 was confirmed. Then three GC cell lines and the human normal gastric epithelial cell line (GES1) were analyzed for the expression level of miR-135b-5p and KLF4 mRNA by RT-qPCR. The BGC-823 GC cell line was chosen for subsequent assays. RESULTS The expression of miR-135b-5p and KLF4 was manipulated via transfection. The changes of proliferation, invasion, migration, viability, cycle and apoptosis of GC cells were evaluated by MTS, colony formation assay, transwell assay, wound healing assay and flow cytometry assay, respectively. Overexpression of MiR-135b-5p enhanced viability, proliferation, invasion and migration of GC cells, increased cell viability and reduced cell apoptosis. Replenishing of KLF4 functioned oppositely. CONCLUSIONS The inhibitory effects of ectopic KLF4 could be attenuated by co-transfection of miR-135b-5p. Collective data suggested that miR-135b-5p has a tumor-promoting role in GC cells via downregulating KLF4. Hence, inhibition of miR-135b-5p could be valuable for treatment of gastric cancer.

Abstract
Background:
Hepatocellular Carcinoma (HCC) is one of the most common cancers associated with deaths worldwide and the presence of valid biomarkers for early diagnosis in high-risk patients can ameliorate the outcome of HCC. Vascular Endothelial Growth Factor (VEGF) has been found to play an essential role in the process of HCC growth and progression.
Objectives:
Therefore, we evaluated the serum VEGF levels in patients with HCC and liver cirrhosis and estimated its significant value for differentiating HCC patients from liver cirrhosis patients.
Material and methods:
Eighty-one subjects were enrolled in the study, 30 patients had HCC, 31 patients had liver cirrhosis and 20 were healthy control subjects. VEGF and AFP were measured using ELIZA. Abdominal ultrasound and triphasic abdominal computed tomography were performed in all subjects. Receiver Operating Characteristics curve analysis was performed for serum VEGF to determine its validity as a tumor biomarker.
Results:
The median levels of the serum VEGF were highly expressed in the HCC group (418 pg/ml) and the liver cirrhosis group (308 pg/ml) with no significant difference (P = 0.767); however both groups showed a significant increase compared to the control group (0.8 pg/ml, P <0.000). Serum VEGF showed high sensitivity (100%) and high specificity (100%) in differentiating HCC patients from controls with a cut-off value of ≥ 64.2 pg/ml, although it showed low sensitivity (29.2%) and specificity (85.7%) for differentiating HCC patients from liver cirrhosis patients.
Conclusion:
VEGF can be used as a reliable biomarker for differentiating HCC patients from healthy subjects but it can't be used as a reliable biomarker for differentiating HCC patients from high-risk patients as liver cirrhosis. The elevated serum VEGF levels in HCC and liver cirrhosis patients can elucidate the crucial role of angiogenesis in HCC and liver cirrhosis.

Abstract
The pathogenesis of hepatocellular carcinoma (HCC) strongly relates to inflammation, with chronic up-regulation of pro-inflammatory mediators standing as a potential unifying mechanism that underscores the origin and progression of HCC independent of aetiology. Activation of the diverse pro-inflammatory mediators either within the tumour or its microenvironment is part of an active cross-talk between the progressive HCC and the host, which is known to influence clinical outcomes including recurrence after radical treatments and long-term survival. A number of clinical biomarkers to measure the severity of cancer-related inflammation are now available, most of which emerge from routine blood parameters including neutrophil, lymphocyte, platelet counts, as well as albuminaemia and C-reactive protein levels. In this review, we summarise the body of evidence supporting the biologic qualification of inflammation-based scores in HCC and review their potential in facilitating the prognostic assessment and treatment allocation in the individual patient. We also discuss the evidence to suggest modulation of tumour-promoting inflammation may act as a source of novel therapeutic strategies in liver cancer.

Abstract
Small nucleolar RNA host gene 15 (SNHG15) is a long noncoding RNA (lncRNA), which promotes progression of multiple cancers. Its specific function in hepatocellular carcinoma (HCC), however, is uncertain. The aims of our study were, therefore, to explore the role of SNHG15 in HCC. SNHG15 and miR-141-3p expression were assessed via quantitative real-time PCR (qRT-PCR) in 58 paired HCC samples and adjacent matched adjacent normal tissues. CCK-8 assay, flow cytometric examination, and wound healing/invasion assays were used to respectively assess how SNHG15 influences cell proliferation, the cell cycle, and the migratory and invasive potential of HCC cells. MicroRNA (miRNAs) that targeted SNHG15 was screened by Starbase2.0 and identified by RNA immunoprecipitation and luciferase reporter assays. SNHG15 expression was markedly increased, whereas miR-141-3p expression was substantially reduced in HCC cells and tissue samples relative to normal controls. When SNHG15 was knocked down, this resulted in a significant disruption to the proliferation, as well as the invasive and migratory ability of these HCC cells. miR-141-3p was also found to be an SNHG15 target in HCC cells. Furthermore, miR-141-3p inhibitor partially reversed the observed SNHG15 depletion-mediated reduction in HCC proliferation, migration, and invasion. By repressing miR-141-3p, SNHG15 could modulate zinc finger E-box binding homeobox 2 (ZEB2) and E2F transcription factor 3 (E2F3) expression, both of which are miR-141-3p targets. These finding suggested that SNHG15 promoted HCC progression via negative regulation of miR-141-3p, thus identifying a potential novel HCC treatment pathway.

Cancer Manag Res 2019; 11:5821-5834. [PMID: 31417317 PMCID: PMC6601050 DOI: 10.2147/cmar.s198615] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/18/2018] [Accepted: 04/07/2019] [Indexed: 12/15/2022] Open
Abstract
Background and purpose: An increasing number of studies have revealed that microRNAs (miRNAs) are the main drivers of hepatocarcinogenesis including progression to later stages of liver cancer. Recently, miR-548b was identified as a cancer-related miRNA in glioma and tongue squamous cell carcinoma. Nonetheless, the expression pattern and specific roles of miR-548b in hepatocellular carcinoma (HCC) have not yet been clarified. Methods: Expression levels of miR-548b in HCC tissues and cell lines were measured by reverse-transcription quantitative PCR. In vitro and in vivo functional assays were performed to determine the effects of miR-548b on the malignant phenotypes of HCC cells. In addition, the molecular mechanisms by which miR-548b regulates the initiation and progression of HCC were investigated in detail. Results: miR-548b expression was weak in HCC tissues and cell lines. The low miR-548b expression significantly correlated with tumor size, TNM stage, and venous infiltration of HCC. In addition, exogenous miR-548b expression suppressed HCC cell proliferation, colony formation, and metastasis and induced apoptosis in vitro. Silencing of miR-548b exerted an opposite effect on these characteristics of HCC cells. Furthermore, miR-548b overexpression hindered tumor growth in vivo. Mechanistic analysis identified high-mobility group box 1 (HMGB1) as a direct target gene of miR-548b in HCC cells. Moreover, an HMGB1 knockdown reproduced the effects of miR-548b upregulation on HCC cells. Recovered HMGB1 expression reversed the effects of miR-548b on HCC cells. Notably, miR-548b overexpression deactivated the PI3K–AKT pathway in HCC cells in vitro and in vivo. Conclusion: Our findings provide the first evidence that miR-548b restrains HCC progression, at least partially, by downregulating HMGB1 and deactivating the PI3K–AKT pathway. Thus, miR-548b might be a novel target for the development of new therapies for HCC.

Abstract
Background: Laparoscopic hepatectomy (LH) has been reported as a safe and efficacious treatment for hepatocellular carcinoma (HCC) patients. However, in cirrhosis patients, LH may be more complex and challenging. So, the short- and long-term outcomes should be well evaluated between LH and open hepatectomy (OH) in HCC patients with cirrhosis. Objectives: To compare the short- and long-term outcomes of LH with OH in HCC patients with cirrhosis. Materials and Methods: The PubMed, EMBASE, and Web of Science were systematically searched to identify the clinical trials published until July 2018 on the comparison of LH and OH in HCC patients with cirrhosis. The statistical analysis was conducted by the Review Manager 5.3 (Cochrane Collaboration, Oxford, United Kingdom). Short-term outcomes included blood loss, operation time, blood transfusion, postoperative complications, mortality, postoperative hospital stay, tumor size, and surgical margin. Long-term outcomes included 1-, 3-, 5-year overall survival (OS) and 1-, 3-, 5-year disease-free survival (DFS). Results: Seventeen studies with 2004 patients were included in this meta-analysis. For short-term outcomes, LH suggested less blood loss, lower blood transfusion rates, reduced occurrence of postoperative complications, wider surgical margin, shorter postoperative hospital stay, and declined rate of mortality (all P < .05). However, there was no significant difference in operation time (P = .67) between the two groups, whereas tumor size was larger in OH (P = .004). As to long-term outcomes, 1-, 3-, 5-year OS and 1-year DFS were higher in LH group (all P < .05). Nevertheless, there were no significant differences in 3- and 5-year DFS (P = .23 and .83, respectively). Conclusions: For the HCC patients with cirrhosis, current evidence suggests that LH shows not only better outcomes in short term, but also a comparable and even improved long-term prognosis.

Abstract
Accumulating evidence suggests that microRNAs (miRNAs) are critical regulators in the development and progression of various malignant tumors, including hepatocellular carcinoma (HCC). Multiple findings have indicated that miRNA-504 (miR-504) is dysregulated in several types of cancers, functioning as an oncogenic miRNA or a tumor suppressive miRNA. However, the role of miR-504 in HCC remains unknown. In this study, we aimed to detect the expression pattern of miR-504 in HCC tissues and cell lines and investigate the precise biological function in HCC cells. Our results showed that miR-504 expression levels were frequently downregulated in both HCC tissues and cell lines. Gain-of-function experiments demonstrated that miR-504 overexpression inhibited the proliferation and invasion in HCC cell lines. By contrast, miR-504 inhibition had the opposite effect. Interestingly, bioinformatics analysis predicted that Frizzled-7 (FZD7) was a potential target gene of miR-504. Dual-luciferase reporter assays confirmed that miR-504 directly targeted the 3'-untranslated region of FZD7 mRNA. In addition, our results showed that miR-504 negatively regulated the mRNA and protein expression of FZD7 in HCC cell lines. Moreover, miR-540 overexpression inhibited the cellular expression of β-catenin and blocked the activation of Wnt signaling in HCC cells. Notably, restoration of FZD7 expression significantly reversed the inhibitory effect of miR-504 on proliferation, invasion, and Wnt/β-catenin signaling in HCC cells. In conclusion, our results demonstrate that miR-504 functions as a tumor suppressive miRNA that inhibits the proliferation and invasion of HCC cells by targeting FZD7 and inhibiting Wnt/β-catenin signaling. Our study provides evidence that miR-504-meidated FZD7/Wnt/β-catenin signaling pathway plays an important role in HCC development and progression and suggests miR-504 as a novel future therapeutic target for treatment of HCC.

Abstract
microRNAs (miRNA/miRs) are a class of small non-coding RNAs; they serve important biological roles in tumorigenesis through the regulation of oncogene expression, and they may be used for the diagnosis and treatment of human cancer. miR-375 was identified to exhibit abnormal expression levels in a number of types of tumor; however, the biological role of miR-375 in human hepatocellular carcinoma (HCC) remains incompletely characterized. The present study investigated the expression of miR-375 in human HCC tissues and human liver cancer cell lines; results from a reverse transcription quantitative polymerase chain reaction analysis indicated that the expression of miR-375 was significantly decreased in tissues and live cancer cell lines, compared with normal tissues and PHH cells. Additional studies demonstrated that the upregulation of miR-375 inhibited human liver cancer cell growth via regulation of cell apoptosis. It was also revealed that the receptor tyrosine-protein kinase erbB-2 (ErbB2) gene was a direct target gene of miR-375, and that the regulation of ErbB2 was associated with the human liver cancer growth. Therefore, the present study demonstrated that miR-375 was expressed at low levels both in human HCC tissues and cell line, compared with normal tissues and PHH cells, and that the induction of miR-375 expression may regulate human liver cancer cell function through targeting the ErbB2 gene, which may potentially improve the diagnosis and treatment of patients with HCC in the future.

Abstract
BACKGROUND & AIMS In recent years, circular RNAs (circRNAs) have been shown to have critical regulatory roles in cancer biology. However, the contributions of circRNAs to hepatocellular carcinoma (HCC) remain largely unknown. METHODS cSMARCA5 (a circRNA derived from exons 15 and 16 of the SMARCA5 gene, hsa_circ_0001445) was identified by RNA-sequencing and validated by quantitative reverse transcription PCR. The role of cSMARCA5 in HCC progression was assessed both in vitro and in vivo. circRNAs in vivo precipitation, luciferase reporter assay, biotin-coupled microRNA capture and fluorescence in situ hybridization were conducted to evaluate the interaction between cSMARCA5 and miR-17-3p/miR-181b-5p. RESULTS The expression of cSMARCA5 was lower in HCC tissues, because of the regulation of DExH-Box Helicase 9, an abundant nuclear RNA helicase. The downregulation of cSMARCA5 in HCC was significantly correlated with aggressive characteristics and served as an independent risk factor for overall survival and recurrence-free survival in patients with HCC after hepatectomy. Our in vivo and in vitro data indicated that cSMARCA5 inhibits the proliferation and migration of HCC cells. Mechanistically, we found that cSMARCA5 could promote the expression of TIMP3, a well-known tumor suppressor, by sponging miR-17-3p and miR-181b-5p. CONCLUSION These results reveal an important role of cSMARCA5 in the growth and metastasis of HCC and provide a fresh perspective on circRNAs in HCC progression. LAY SUMMARY Herein, we studied the role of cSMARCA5, a circular RNA, in hepatocellular carcinoma. Our in vitro and in vivo data showed that cSMARCA5 inhibits the growth and migration of hepatocellular carcinoma cells, making it a potential therapeutic target.

Abstract
Hepatocellular carcinoma (HCC) is the fifth most common cancer around the world, along with high mortality and metastasis rate. Our present study aimed to explore the role of LncRNA HOTAIR in the progression of HCC. Our data showed that HOTAIR was overexpressed in HCC tissues and cell lines (Huh7, Hep3B, HepG2, MHCC97H). Overexpressed HOTAIR promoted invasion and migration of HCC cells (Huh7) by enhancing epithelial-mesenchymal transition (EMT). Besides that, miR-23b-3p was predicted to be a target of HOTAIR and decreased expression of miR-23b-3p was observed in HCC tissues and cell lines. The up-regulation of HOTAIR strongly decreased the expression of miR-23b-3p. The further luciferase report confirmed the targeting reaction between HOTAIR and miR-23b-3p, suggesting that the expression of miR-23b-3p was negatively regulated by HOTAIR. Moreover, the zinc-finger E-box-binding homeobox 1 (ZEB1) protein was predicted to be a target of miR-23b-3p. The expression of ZEB1 was negatively regulated by miR-23b-3p while positively regulated by HOTAIR. Besides that, transfection with miR-23b-3p mimic counteracted the promoting effects of HOTAIR on invasion, migration and EMT of HCC cells. Our in vitro experiments suggested that HOTAIR promoted invasion and migration of HCC cells through enhancing EMT via sponging miR-23b-3p from ZEB1. Finally, the in vivo experiments indicated that HOTAIR could promote metastasis of HCC by enhancing EMT in vivo. Taken together, our study demonstrated that the HOTAIR-miR-23b-3p-ZEB1 axis may provide a new perspective for treatment of HCC.

Liu C, Li L, Lu WS, Du H, Yan LN, Wen TF, Wei WR, Jiang L, Xu MQ. A novel combined systemic inflammation-based score can predict survival of intermediate-to-advanced hepatocellular carcinoma patients undergoing transarterial chemoembolization. BMC Cancer 2018; 18:216. [PMID: 29466970 PMCID: PMC5822668 DOI: 10.1186/s12885-018-4121-3] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2017] [Accepted: 02/12/2018] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND There is currently limited information regarding the prognostic ability of the dNLR-PNI (the combination of the derived neutrophil-to-lymphocyte ratio [dNLR] and prognostic nutritional index [PNI]) for hepatocellular carcinoma (HCC). This study aimed to assess the predictive ability of the dNLR-PNI in patients with intermediate-to-advanced HCC after transarterial chemoembolization (TACE). METHODS A total of 761 HCC patients were enrolled in the study. The dNLR-PNI was retrospectively calculated in these patients, as follows: patients with both an elevated dNLR and a decreased PNI, as determined using the cutoffs obtained from receiver operating characteristic curve analysis, were allocated a score of 2, while patients showing one or neither of these alterations were allocated a score of 1 or 0, respectively. RESULTS During the follow-up period, 562 patients died. Multivariate analysis suggested that elevated total bilirubin, Barcelona Clinic Liver Cancer C stage, repeated TACE, and dNLR-PNI were independently associated with unsatisfactory overall survival. The median survival times of patients with a dNLR-PNI of 0, 1, and 2 were 31.0 (95% confidence interval [CI] 22.5-39.5), 16.0 (95% CI 12.2-19.7) and 6.0 (95% CI 4.8-7.2) months, respectively (P < 0.001). CONCLUSIONS The dNLR-PNI can predict the survival outcomes of intermediate-to-advanced HCC patients undergoing TACE, and should be further evaluated as a prognostic marker for who are to undergo TACE treatment.

Abstract
Curcumin is an active component of turmeric, which is derived from the rhizomes of Curcuma longa. Glycyrrhetinic acid (GA) is a natural compound extracted from liquorice. Both curcumin and GA are widely used as anticancer agents for treating many human cancers. In this study, curcumin and GA were used separately and in combination to treat human hepatocellular carcinoma (HCC) HepG2 cells. MTT assays were used to evaluate cell proliferation. Flow cytometry was carried out to measure cell apoptosis and determine cell cycle progression. Western blot analyses were applied to determine the expression levels of B-cell lymphoma-2 (Bcl-2), B-cell associated X protein (Bax), phosphatase and tensin homolog (PTEN), phosphorylated phosphoinositide 3-kinase (PI3K) and AKT serine/threonine kinase 1 (Akt). The results showed that combined treatment with curcumin and GA resulted in a significant reduction in proliferation and an increase in apoptosis and G1 cell cycle arrest in HepG-2 cells. A xenograft tumour model showed that curcumin and GA suppressed HCC development in vivo. Moreover, by knocking down the expression of PTEN, we confirmed that curcumin and GA exert their anticancer effects by inhibiting the PTEN/PI3K/Akt signalling pathway. Collectively, these results indicate that the combination of curcumin and GA could effectively inhibit the development of HepG2 cells by inhibiting PTEN/PI3K/Akt signalling and could be a promising treatment strategy for patients with HCC.

Abstract
Hepatocellular carcinoma (HCC) is the third leading cause of cancer mortality worldwide. In this study, we had analysed the copy number variations and heteroplasmic mutations of mitochondria (MT) in 88 HCC individuals. The average copy number of MT genome in normal samples was significantly greater than that in tumor samples. Overall, the number of heteroplasmic mutations in 88 tumor and their matched normal samples were 241 and 173, respectively. There was higher positive ratio of heteroplasmic mutations in tumor samples (86%) than normal samples (73%). Worthwhile mention, ND1 gene harbored greater mutation frequency and more nonsynonymous mutations in tumor samples. Interestingly, 202 tumor-specific heteroplasmic mutations were detected. Moreover, ND1, ND3, ND4, ND5 and ND6 genes had higher ratio of nonsynonymous versus synonymous mutations in tumor-specific heteroplasmic mutations. It might suggest that the disorder of NADH dehydrogenase (complex I) resulted by heteroplasmic mutations may have close relation with tumorigenesis of hepatocellular carcinoma. This study provided theoretical basis for further understanding mechanism of tumorigenesis from the perspective of mitochondrial heteroplasmic mutations.

Abstract
Hepatocellular carcinoma (HCC) is the most common type of hepatic cancer and is particularly a problem in China. Bio-molecular markers have been demonstrated to be of prognostic significance and might help predict tumor behavior. In our study, we aimed to assess the prognostic values of DNA methyltransferase 1 (DNMT1), HLA-DRα, and β-catenin, as well as the combined use of molecular biomarkers, clinicopathological parameters and the TNM staging system to find a method for superior prognostic performance for HCC by analyzing a Chinese HCC cohort. We revealed the significant prognostic roles of DNMT1 (OR: 2.570; 95% CI: 1.401-4.715; P = 0.002) and HLA-DRα (0.350; 0.189-0.616; 0.001), and further developed an estimation formula to predict prognosis in HCC patients after curative resection, based on TNM staging, operative blood loss, abnormal total bilirubin, DNMT1 and HLA-DRα. The receiver operating characteristic curve analysis showed that prediction from the multivariate logistic regression had an area of 0.847 and performed better than the conventional TNM staging system, as well as other current HCC staging systems. Our study demonstrated the prognostic values of DNMT1 and HLA-DRα in HCC patients after curative resection. Additionally, we developed a prognostic estimation formula featured better stratification ability than the conventional TNM staging and provided a practicable stratification method for HCC patients after curative resection.

Abstract
Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer in adults and effective therapy for human liver cancer remains a difficult clinical concern. Researchers have demonstrated that microRNAs play important roles in the tumorigenesis and tumor progression of human liver cancer; therefore, regulation of microRNAs may be a new strategy for HCC therapy. MicroRNA-196a (miR-196a) has been reported to be overexpressed in many types of cancers. However, the regulatory effects of miR-196a in human liver cancer are not fully understood. In the present study, we found that miR-196a was overexpressed in human liver cancer cells compared to that observed in normal liver cells. MTT and colony formation assays indicated that downregulation of miR-196a inhibited liver cancer cell proliferation which was due to the induction of cell apoptosis. A mouse model demonstrated that downregulation of miR-196a also inhibited human liver cancer cell migration and invasion in vivo. Further study indicated that FOXO1 is a direct target of miR-196a, and inhibition of FOXO1 promoted human liver cancer cell growth. Taken together, the present study demonstrated that the expression of miR-196a in human liver cancer cells was upregulated; downregulation of miR-196a regulated human liver cancer cell biological functions which could benefit the clinical therapy of human liver cancer in the future.

Abstract
MicroRNAs (miRNAs) play critical roles in hepatocellular carcinoma (HCC). However, the expression and biological function of miR-345 in HCC remain unknown. The present study demonstrated that miR-345 expression was reduced in HCC tissues and cell lines. Decreased miR-345 expression was associated with unfavorable clinical features and poor prognosis. In vitro functional assays showed that miR-345 overexpression inhibited the migration and invasion of MHCC-97H cells while miR-345 knockdown promoted metastatic behavior of Hep3B cells. In vivo experiments showed that miR-345 overexpression inhibited while miR-345 knockdown promoted lung metastasis of HCC cells in nude mice. Mechanically, YAP1 was identified to be the downstream target of miR-345 in HCC cells. YAP1 overexpression reversed the inhibitory effects of miR-345 on MHCC-97H migration and invasion, while YAP1 knockdown reduced the promoting effects of miR-345 knockdown on the metastatic behavior of Hep3B cells.

Abstract
Approximately 50% hepatocellular carcinoma patients meeting the Milan criteria utilized to develop an improved prognostic model for predicting the recurrence in these patients. Using univariate and multivariate analysis, cytokeratin-19 and glypican-3 expression patterns, tumor number and histological grading from eight putative prognostic factors comprised the risk factor scoring model to predict the tumor recurrence. In the training cohort, the area under roc curve (AUC) value of the model was 0.715 [95% confidence interval (CI) = 0.645-0.786, P<0.001], which was the highest among all the parameters. The performance of the model was assessed using an independent validation cohort, wherein the AUC value was 0.760 (95% CI=0.647-0.874, P<0.001), which was higher than the other factors. The results indicated that model had high performance with adequate discrimination ability. Moreover, it significantly improved the predictive capacity for the recurrence in patients with hepatocellular carcinoma within the Milan criteria after radical resection.

Abstract
A number of recent studies have focused on the association between long non-coding RNAs (lncRNAs) and cancer. HOX transcript antisense RNA (HOTAIR), an lncRNA that functions as a transcriptional modulator, has been implicated in various fundamental biological activities. HOTAIR mediates the trimethylation of histone H3 at lysine 27 and the demethylation of histone H3 dimethyl Lys4 by recruiting the polycomb repressive complex 2 and the lysine-specific demethylase 1/co-repressor of RE1-silencing transcription factor (coREST)/REST complex to the target gene promoters, which leads to gene silencing. Overexpression of HOTAIR in hepatocellular carcinoma (HCC) is strongly associated with an unfavorable prognosis for patients with HCC. HOTAIR promotes the carcinogenic activity of HCC cells through the suppression of RNA binding motif protein 38, triggering the epithelial-mesenchymal transition, and by interacting with microRNAs that act as tumor suppressors. In the present review, the role of the lncRNA HOTAIR in HCC is examined. The potential use of HOTAIR as a biomarker to achieve more accurate prognostic predictions and as an effective therapeutic target for HCC is then discussed.

Abstract
Increasing evidence indicates that the dysregulation of miRNAs that act as tumor suppressors or oncogenes is involved in tumorigenesis. However, the role of miR-539 in hepatocellular carcinoma (HCC) has not been well investigated. Quantitative RT-PCR (qRT-PCR), proliferation assay, colony formation assay, migration and invasion assays, western blotting, and xenograft tumor growth models were performed to assess the expression levels and functions of miR-539 in HCC. Luciferase reporter assays, qRT-PCR, western blotting, and immunohistochemistry were used to identify and verify the targets of miR-539. miR-539 was significantly downregulated in HCC cell lines and tissue samples. Ectopic expression of miR-539 inhibited cell viability, proliferation, migration, and invasion in vitro and suppressed xenograft tumor growth in vivo. Fascin homologue 1 (FSCN1) was verified as a direct target of miR-539, and overexpression of FSCN1 promoted HCC cell migration and invasion. miR-539 acts as a novel tumor suppressor in the development and progression of HCC by targeting FSCN1, providing new insight into the mechanisms of HCC carcinogenesis and suggesting that miR-539 may be a therapeutic target.

Abstract
We aimed to elucidate the effects of hepatoma-derived growth factor (HDGF) on growth and metastasis of hepatocellular carcinoma (HCC) cells. Tissue microarrays with 236 HCC specimens and 18 extrahepatic metastases were utilized to detect the HDGF expression by immunohistochemistry. Meanwhile, HDGF expressions in HCC cell lines with different metastatic potentials were examined using immunofluorescence staining, real-time PCR and western blotting. After HDGF silencing, the growth and metastatic potentials of HCC cells were evaluated by soft agar assay, invasion assay, together with tumorigenicity assay in nude mice. The gelatin zymography was performed by detecting MMP-2 and MMP-9 levels. Additionally, western blotting was conducted to determine the levels of total and phosphorylated ERK1/2, JNK, p38 and Akt. The results showed that HDGF was overexpressed in HCC metastasis tumour, and the expression increased with the differentiation degree of tumours (Grade I 44.0%, Grade II 48.4% and Grade III 65.6%). Consistently, HDGF levels were positively associated with the metastatic capability of HCC cells (MHCC97L < MHCC97H < HCCLM3). The growth and metastasis were suppressed by HDGF-siRNA. Gelatinolytic activities were enhanced in the three metastatic HCC cell lines, but had no significant difference among them. The tumourigenicity and metastatic capability of HCCLM3 cells in nude mice were inhibited after silencing HDGF. Meanwhile, HDGF-siRNA specifically suppressed the total and phosphorylated protein levels of ERK1/2, while not JNK, p38 and Akt. In conclusion, HDGF was overexpressed in HCC patients and cells, and HDGF might be closely correlated with HCC metastasis via regulating ERK signalling pathway.

Abstract
Hepatocellular carcinoma (HCC) is one of the most aggressive tumors in humans. T lymphocytes and natural killer (NK) cells are the body's first line of defense to prevent tumor cell growth. Previous studies have demonstrated that transcatheter arterial chemoembolization (TACE) combined with argon-helium cryosurgery system (AHCS) can effectively treat liver cancer. However, the mechanism of the treatment is unclear yet. In the current study, we investigated the effects of TACE combined with AHCS on the changes of T cell subsets and NK cells in peripheral blood of HCC. Our data show that alpha-fetoprotein (AFP) levels in peripheral blood were significantly up-regulated in HCC patients before treatment when compared with healthy people and reduced after TACE combined with AHCS treatment (P < 0.01). In addition, we found that CD4+ cells and NK cells decreased (P < 0.05) and CD8+ cells increased (P < 0.05) in HCC patients when compared with healthy people. After treatment, the CD4+ cells, CD4+/CD8+ ratio, and NK cells were dramatically increased in HCC patients (P < 0.05). In contrast, CD8+ cells were significantly decreased (P < 0.05). TACE combined with AHCS treatment significantly prolonged 1-year survival rate of HCC patients and did not show significant side effects. Taken together, our data indicate that TACE combined with AHCS treatment improves patients' immune system. It is a feasible and effective therapeutic method for HCC patients.

Abstract
Metastasis is one of the causes of cancer death. Functions and mechanisms of microRNAs (miRNAs) involved in hepatocellular carcinoma (HCC) metastasis are largely unknown. Here, a miRNA microarray analysis was performed in MHCC-97L, MHCC-97H and HCC-LM3 cells with gradually increasing metastatic potential to disclose crucial miRNAs involved in HCC metastasis. miR-192 expression decreased and negatively correlated with vascular invasion in HCC specimens. Gain and loss of function studies revealed that miR-192 significantly suppressed metastasis of HCC cells in vitro and in vivo. Solute carrier family 39 member 6 (SLC39A6) was identified as a direct and functional target of miR-192. In addition, SLC39A6 negatively correlated with miR-192 in HCC samples and promoted HCC cell migration and invasion. Moreover, miR-192 decreased SLC39A6 expression, subsequently downregulating SNAIL and upregulating E-cadherin expression. Suppression of migration and invasion caused by miR-192 overexpression was alleviated by exogenous Snail expression. Intriguingly, lower miR-192 expression and higher SLC39A6 expression significantly contributed to poorer outcomes in HCC patients. Multivariate analysis indicated that miR-192 was an independent and significant predictor of HCC patient overall survival. In conclusion, we newly determined that miR-192 targeted the SLC39A6/SNAIL pathway to reduce tumor metastasis in HCC cells. This axis provided insights into the mechanism underlying miRNA regulation of HCC metastasis and a novel therapeutic target for HCC treatment.

Abstract
Cripto-1 could promote tumorigenesis in a wide range of carcinomas, yet little is known in hepatocellular carcinoma (HCC). The expression of Cripto-1 and MMP-9 were assessed by immunohistochemistry in 205 HCC specimens. The correlation between Cripto-1 and MMP-9, clinicopathological/prognostic value in HCC was examined. Cripto-1 overexpression was correlated with larger tumor, TNM stage, BCLC stage and tumor recurrence. In multivariate analyses, Cripto-1 was an independent predictor for overall survival (OS) and time to recurrence (TTR). Cripto-1 expression was increased in TNM and BCLC stage-dependent manner. Cripto-1 overexpression was associated with poor prognosis in patients subgroups stratified by tumor size, tumor differentiation, TNM and BCLC stage. In addition, Cripto-1 was positively correlated with MMP-9 among 205 HCC samples. Patients with Cripto-1 upregulation had poor OS and shorter TTR in low and high aggressiveness groups. Furthermore, Cripto-1 had predictive validity for early and late recurrence in HCC patients. Combination of Cripto-1 and serum AFP was correlated with OS and TTR. In conclusion, Cripto-1 overexpression contributes to aggressiveness and poor prognosis of HCC. Cripto-1/AFP expression could be a potential prognostic biomarker for survival in HCC patients.

Abstract
High-sensitivity and -specificity diagnostic techniques to detect early-stage hepatocellular carcinoma (HCC) are in high demand. Screening with serum HCC markers, such as alpha-fetoprotein, is not practical because they possess poor sensitivity and specificity. As such, we focused on glycan alterations of glycoproteins found in patient sera in an attempt to discover novel HCC markers that are more specific and sensitive than current HCC markers. Sera from 42 HCC patients and 80 controls, composed of 27 chronic hepatitis B patients, 26 chronic hepatitis C patients, and 27 healthy volunteers, were analyzed in this study. Glycopeptides obtained from serum proteins by trypsin digestion were enriched by ultrafiltration and Aleuria aurantia lectin-based affinity chromatography, followed by analysis using liquid chromatography time-of-flight mass spectrometry. The data were analyzed by our newly developed software, which calculates peak intensities and positions (m/z and elution time), aligns all sample peaks, and integrates all data into a single table. HCC markers were extracted from more than 30 000 detected glycopeptide peaks by t test, mean-fold change, and ROC analyses. As a result, we revealed that alpha-1-acid glycoprotein with multifucosylated tetraantennary N-glycans was significantly elevated in HCC patients, whereas the single fucosylated derivative was not.

Abstract
Natural killer (NK) cells have been demonstrated to inhibit tumor growth. However, the role of NK cells in the inhibition of hepatocellular carcinoma metastasis is not well understood. The present study aimed to investigate the roles that NK cells may serve in inhibiting hepatocellular carcinoma metastasis. The role of isolated NK cells in the inhibition, proliferation, migration and invasion of the hepatoma cell line, MHCC97-H, was examined in vitro. Additionally, the survival rate of NK cells labeled with carboxyfluorescein diacetate-succinimidyl ester was assessed in vivo. An orthotopic implantation model was used to evaluate the role of NK cells in suppressing MHCC97-H cells in vivo. The effect of interleukin (IL)-2 stimulation on the tumor-inhibitory role of the NK cells was measured indirectly by analyzing the expression of various NK cell receptors and activated NK cell markers. It was observed that the NK cells inhibited the proliferation, migration and invasion of the MHCC97-H cells in vitro. Furthermore, the NK cells demonstrated long-term survival in the livers of the nude mice, and inhibited lung metastasis of hepatocellular carcinoma in vivo. However, liver tumor growth was not inhibited by the NK cells. IL-2 was identified to enhance the tumor-inhibitory effect of NK cells. The present study concludes that IL-2 may enhance the antitumor activity of the NK cells, and thereby inhibit the metastases of hepatocellular carcinoma in mice.

Abstract
AIMS The present study was designed to evaluate the different expression of ubiquitin-like with PHD and ring finger domains 1 (UHRF1) in hepatocellular carcinoma (HCC) tissues and the adjacent normal tissues, further explore the correlation between UHRF1 expression and the prognosis of HCC patients. METHODS The UHRF1 expression at protein level in HCC tissues and the adjacent normal tissues were measured by high performance liquid chromatography (HPLC). Chi-square test was used to estimate the relationship between UHRF1 expression and clinicopathologic characteristics of HCC patients. The overall survival of HCC patients with diverse expression of UHRF1 was measured by Kaplan-Meier analysis. Cox regression analysis was conducted to judge the prognostic value of UHRF1 in HCC patients. RESULTS The UHRF1 was over-expressed in HCC tissues compared with the adjacent normal tissues according to the outcome of HPLC (P<0.001). Besides, the UHRF1 expression was tightly related to distant metastasis, cancer area, and HBV (P<0.05), but shared no correlation with gender, cirrhosis, and bilirubin (P>0.05). Patients with high UHRF1 expression had a shorter overall survival time than those with low UHRF1 expression (P<0.001). Cox regression analysis showed that UHRF1 was significantly linked with the prognosis of HCC patients (P=0.002, HR=5.807, 95% CI=1.901-17.742). CONCLUSION UHRF1 was over-expressed in HCC tissues compared to the adjacent normal tissues and UHRF1 expression shared significant relevance with distant metastasis, cancer area and HBV. It could be an important and independent prognostic biomarker for HCC patients.

Abstract
Emerging evidence suggests that microRNAs (miRNAs) play important roles in regulating HCC development and progression; however, the mechanisms by which their specific functions and mechanisms remained to be further explored. miR-129 has been reported in gastric cancers, lung cancer and colon cancer. In this study, we disclosed a new tumor suppresser function of miR-129 in HCC. We also found the downregulation of miR-129 occurred in nearly 3/4 of the tumors examined (56/76) compared with adjacent nontumorous tissues, which was more importantly, correlated to the advanced stage and vascular invasion. We then demonstrated that miR-129 overexpression attenuated HCC cells proliferation and invasion, inducing apoptosis in vitro. Moreover, we used miR-129 antagonist and found that anti-miR-129 promoted HCC cells malignant phenotypes. Mechanistically, our further investigations revealed that miR-129 suppressed cell proliferation and invasion by targeting the 3'-untranslated region of PAK5, as well as miR-129 silencing up-regulated PAK5 expression. Moreover, miR-129 expression was inversely correlated with PAK5 expression in 76 cases of HCC samples. RNA interference of PAK5 attenuated anti-miR-129 mediated cell proliferation and invasion in HCC cells. Taken together, these results demonstrated that miR-129 suppressed tumorigenesis and progression by directly targeting PAK5, defining miR-129 as a potential treatment target for HCC.
