Abstract
Grass carp hemorrhagic disease is a fatal disease caused by the grass carp reovirus (GCRV). The aberrant regulation of transcripts has been implicated in many types of diseases. In the present study, we characterized mRNA and miRNA transcriptomes of different virulent GCRVs using RNA sequencing (RNA-Seq). One hundred eighteen miRNAs were identified as being differentially expressed between different virulent viruses in grass carp fibroblasts. Eight miRNAs were selected to verify the RNA-Seq results using RT-PCR and mRNA methods. In total, 996 differentially expressed mRNA genes were identified in grass carp fibroblasts, while 901 miRNA-mRNA target pairs were observed to be inversely regulated in grass carp fibroblasts. Integrated mRNA/miRNA expression profiling analysis results showed that the most influenced processes were the immune response and cell death. Three miRNAs were shown to exhibit the same expression patterns when two different methods were used and had important functions during viral infection. These results provide insights into the miRNA-mediated regulation of mRNA and valuable resources on transcript variation and regulation during GCRV infection, which are potentially useful for mechanistic and drug studies.

Abstract
Although the role of autophagy has been implicated in several forms of chronic hepatitis, it is still not fully understood. Active autophagy eliminates damaged molecules and organelles (such as mitochondria) by lysosomal degradation. In the present study, we aimed to examine and compare autophagy activity in chronic hepatitis C (CHC) and autoimmune hepatitis (AIH) by detecting the expression of autophagy (LC3 and p62) and mitochondrium-related (TOMM20) proteins, as well as the levels of selected microRNAs (miR-101, -155, -204 and - 224) known to be involved in the regulation of autophagy. In addition, the expression levels were related to pathohistological parameters. Liver biopsy samples, including 45 CHC and 18 AIH cases, were immunohistochemically stained for LC3, p62 and TOMM20 and the expression of miRNAs was determined using real-time PCR. We found elevated LC3 and p62 in AIH samples as compared with CHC ones, indicating an activated autophagy that is impaired in AIH as no degradation of p62 seemed to occur. Moreover, p62 showed strong correlation with necroinflammatory grades in the AIH group. The observed elevated levels of TOMM20 and p62 suggest a less efficient elimination of damaged mitochondria in AIH as opposed to CHC, in which autophagy seems to have a more active function. The level of miR-101 was increased in case of CHC as compared with AIH, however, miR-155, -204 and 224 resulted in no expressional. Furthermore, miR-224 level correlated with steatosis and miR-155 expression with fibrosis stage in CHC. In conclusion, dissimilar autophagic activity was observed in CHC and AIH, suggesting a close association between impaired autophagy and severity of necroinflammation. This impairment may not be regulated by the analyzed miRNAs. Nevertheless, miR-224 and - 155 seem to be associated with CHC progression.

Abstract
Introduction Treatment of HCV using a combination of pegylated interferon (PEG-IFN) and ribavirin fails in about 40% of the patients with HCV genotype 4 infections, and it is physically and economically demanding. Thus, it is highly important to identify factors that can help to predict the likelihood that a patient will respond to this treatment. Methods In this study, five miRNAs, i.e., miRNA-122, miRNA-199, miRNA-192, miRNA-30, and miRNA-128, were selected according to previous studies that demonstrated their noticeable functions in viral replication, indicating that they potentially could be used by host cells to control viral infections. The five miRNAs were measured using real-time, reverse transcription-polymerase chain reactions. The data were analyzed using the t-test and chi-squared test. Results We found that the expression level of miRNA-122 was significantly increased in the responders’ group (p < 0.01) over that in the non-responders’ groups before and after treatment; both increased significantly (p < 0.01) compared with the normal control group. Conclusion miR-122 might be a useful predictor for virological responses to treatment with PEG-interferon plus ribavirin therapy in patients with HCV.

Abstract
Although, the treatment of chronic hepatitis C (CHC) greatly improved with the use of direct antiviral agents, pegylated-interferon (PEG-IFN) plus ribavirin remains an option for many patients, worldwide. The intra-hepatic level of expression of interferon stimulated genes (ISGs) and the rs12979860 CC genotype located within IFNL3 have been associated with sustained virological response (SVR), in patients with CHC. The aim of the study was to identify micro-RNAs associated with SVR and to build an accurate signature to predict SVR. Pre-treatment liver biopsies from 111 patients, treated with PEG-IFN plus ribavirin, were studied. Fifty-seven patients had SVR, 36 non-response (NR) and 18 relapse (RR). The expression of 851 human miRNAs and 30 selected mRNAs, including ISGs, was assessed by RT-qPCR. In the first group of patients (screen), 20 miRNAs out of the 851 studied were deregulated between NRs and SVRs. From the 4 miRNAs validated (mir-23a, mir-181a*, mir-217 and mir-99a), in the second group of patients (validation), 3 (mir-23a, mir-181a* and mir-99a) were down-regulated in NRs as compared to SVRs. The ISGs, studied, were accumulated in SVRs and IFNL3 rs12979860 CT/TT carriers compared respectively to NRs and CC carriers. Combining, clinical data together with the expression of selected genes and micro-RNAs, we identified a signature (IFI35, mir-99a and HCV genotype) to predict SVR (AUC:0.876) with a positive predictive value of 86.54% with high sensibility (80%) and specificity (80.4%). This signature may help to characterize patients with low chance to respond to PEG-IFN/ribavirin and to elucidate mechanisms of NR.

Abstract
UNLABELLED Biliary complications (BCs) remain one of the most outstanding factors influencing long-term results after orthotopic liver transplantation. The authors carried out a systematic overview of 1720 papers since 2008, and focused on 45 relevant ones. Among 14,411 transplanted patients the incidence of BCs was 23%. Biliary leakage occurred in 8.5%, biliary stricture in 14.7%, mortality rate was 1-3%. RISK FACTORS preoperative sodium level; p = 0.037, model of end-stage liver disease score >25; p = 0.048, primary sclerosing cholangitis; p = 0.001, malignancy; p = 0.026, donor age >60, macrovesicular graft steatosis; p = 0.001, duct-to-duct anastomosis; p = 0.004, long anhepatic phase; p = 0.04, cold ischemic time >12 h; p = 0.043, use of T-tube; p = 0.032, insufficient flush of bile ducts; p = 0.001, acute rejection; p = 0.003, cytomegalovirus infection; p = 0.004 and hepatic artery thrombosis; p = 0.001. The management was surgical in case of biliary leakage, and interventional radiology or endoscopic retrograde cholangiopancreatography in case of biliary stricture. Mapping of miRNA profile is a new field of research. Nemes-Doros score is a useful tool in the estimation of hepatic artery thrombosis. Management of BCs requires a multidisciplinary expert team.

Abstract
BACKGROUND Introduction of combined antiretroviral therapy (cART) has improved survival of HIV infected individuals, while the relative contribution of liver-related mortality increased. Especially in HIV/HCV-coinfected patients hepatic fibrosis and portal hypertension represent the main causes of liver-related morbidity and mortality. Circulating miRNA-122 levels are elevated in HIV patients and have been shown to correlate with severity of liver injury. However, the association of miRNA-122 levels and hepatic fibrosis and portal hypertension remains to be explored in HIV/HCV coinfection. METHODS From a total of 74 (31% female) patients with HIV/HCV coinfection were included. Serum levels of miRNA-122 were analyzed by quantitative polymerase chain reaction (PCR) and normalized to SV-40 spike-in RNA. Hepatic venous pressure gradient (HVPG) was measured in 52 (70%) patients and the fibrosis stage was determined in 63 (85%) patients using transient elastography. RESULTS The levels of circulating miRNA-122 were increased in HIV/HCV coinfected patients and significantly correlated with the alanine aminotransferase (ALT) (rs = 0.438; p<0.001) and aspartate transaminase AST values (rs = 0.336; p = 0.003), but not with fibrosis stage (p = n.s.). Interestingly, miRNA-122 levels showed an inverse correlation with hepatic venous pressure gradient (HVPG) (rs = -0.302; p = 0.03). CONCLUSION Elevated miRNA-122 levels are associated with liver injury, and with low HVPG. Though, miRNA-122 levels are not suitable to predict the degree of fibrosis, they might function as indicators for portal hypertension in HIV/HCV coinfected patients.

Abstract
The upregulation of miR-221 has been reported in variety of cancer, including HCV associated HCC, the mechanism of upregulation of miR-221 however remains unclear. In this study, it was found that miR-221 was significantly upregulated in serum of patients with HCV associated chronic hepatitis (cHCV), which suggested the possible biological significance of miR-221 in HCV infection. Important, the upregulated miR-221 was positive correlation with serum miR-122, alanine aminotransferase (ALT) and aspartate transaminase (AST), which are reported as biomarkers for liver injuries. Further studies indicated that HCVcc infection activated nuclear factor-kappa B (NF-κB) and the upregulation of miR-221 by HCVcc infection could totally blocked by NF-κB inhibitor (pyrrolidine dithiocarbamate, PDTC). In conclusion, HCVcc infection could upregulate the expression of miR-221 in NF-κB dependent manner.

Abstract
MicroRNAs (miRNAs) are a class of small noncoding RNAs that post-transcriptionally regulate the expression of many target genes via mRNA degradation or translation inhibition. Many studies have shown that miRNAs are involved in the modulation of gene expression and replication of hepatitis B virus (HBV) and hepatitis C virus (HCV) and play a pivotal role in host-virus interactions. Increasing evidence also demonstrates that viral infection leads to alteration of the miRNA expression profile in hepatic tissues or circulation. The deregulated miRNAs participate in hepatocellular carcinoma (HCC) initiation and progression by functioning as oncogenes or tumor suppressor genes by targeting various genes involved in cancer-related signaling pathways. The distinct expression pattern of miRNAs may be a useful marker for the diagnosis and prognosis of virus-related diseases considering the limitation of currently used biomarkers. Moreover, the role of deregulated miRNA in host-virus interactions and HCC development suggested that miRNAs may serve as therapeutic targets or as tools. In this review, we summarize the recent findings about the deregulation and the role of miRNAs during HBV/HCV infection and HCC development, and we discuss the possible mechanism of action of miRNAs in the pathogenesis of virus-related diseases. Furthermore, we discuss the potential of using miRNAs as markers for diagnosis and prognosis as well as therapeutic targets and drugs.

MicroRNAs (miRNAs) are among the most promising in this field. MiRNAs are small noncoding RNAs that function as important regulators of gene expression in response to cellular stress and disease. An advantage that makes miRNAs attractive candidates for biomarker research is their fast release from cells in response to stress and injury, which can occur via different routes. In the context of liver transplantation (LT), noninvasive measurement and stability of extracellular miRNAs in blood, bile, and graft perfusates has been linked to cell-type specific injury and early graft outcome following LT. Furthermore, specific intrahepatic miRNA expression patterns have been associated with graft survival and recurrent disease, like hepatitis C virus-related fibrosis and hepatocellular carcinoma. Therefore, miRNAs with strong predictive value and high sensitivity and specificity might be successfully applied to assess hepatic injury and to diagnose (recurrent) liver disease before, during and after LT. In this review, the current features and future prospects of miRNAs as biomarkers in and out of the liver are discussed.

Abstract
OBJECTIVE The tetraspanin CD81 is one of the main receptors involved in hepatitis C virus entry. Herein, we aimed to explore the role of microRNAs in regulating CD81 receptor expression and function. PATIENTS AND METHODS Bioinformatics analysis was carried out to select potential mircroRNAs that binds CD81 3'untranslated region. Liver biopsies taken from 28 HCV genotype- 4 patients and 10 healthy donors were screened. Naïve, JFH1 and ED43/JFH1- infected- Huh7 cells were transfected with mimics and inhibitors followed by analyzing CD81 protein and mRNA expression. This was done using flow cytometry and Q-RT PCR, respectively. HCV entry into Huh7 cells was investigated post-transfection. Binding confirmation was done using luciferase reporter vector harboring wild/mutant target sites of microRNA. The impact of Epigallocatechin-gallate on modulating microRNA/CD81 expression was assessed. RESULTS Bioinformatics revealed that CD81 is a potential down-stream target for miR-194. A significant inverse correlation was found between miR-194 and CD81 expression in liver biopsies of HCV patients. Forcing the expression of miR-194 showed a down-regulation of CD81 protein, mRNA expression and significantly abrogated the HCV infectivity of Huh7 cells. Stimulation with EGCG enhanced mir-194 expression and down-regulated CD81 expression. CONCLUSION This study showed that mir-194 hinders HCV entry through targeting CD81 receptors.

Abstract
Investigations into the role of microRNA (miRNA) in hepatitis C virus (HCV) infection, disease pathogenesis and host immune and treatment response have potential to produce innovations in diagnosis, prognosis and therapy. However, investigational challenges remain in generating clinically useful and reproducible results. We review the literature with a primary emphasis on methods and technologies used to construct our current understanding of miRNA and HCV disease. A second emphasis is to understand potential clinical research applications and provide clarification of previous study results. Many miRNA have key roles in viral and immunopathogenesis of HCV infection across multiple tissue compartments. Controversy exists among published studies regarding relative measurements, temporal changes and biological significance of specific miRNA and HCV infection. To reconcile diverging data, additional research into optimal sample processing, in vitro models, techniques for microarray differential expression of miRNAs, practices for sample result normalization, and effect of HCV genotype variation on expression are all necessary. Microarray and miRNA isolation techniques should be selected based on ability to generate reproducible results in the sample type of interest. More direct comparisons of efficacy and reliability of various multiplex microarrays and an improved consensus around miRNA normalization and quantitation are necessary so that data can be compared across studies.

Abstract
It is well-established that the host microRNA (miRNA) milieu has a significant influence on the etiology of disease. In the context of viruses, such as hepatitis C virus (HCV), microRNAs have been shown to influence viral life cycles both directly, through interactions with the viral genome, and indirectly, through regulation of critical virus-associated host pathways. Several miRNA profiling studies have demonstrated that HCV infection aberrantly regulates a significant number of human miRNA. However, the biological relevance of these modulations remains poorly understood. In this review, we summarize recent research that has shed light on the pro-viral and anti-viral roles of HCV-induced changes in human miRNA expression and their significance in the development of HCV related sequelae and response to therapy.

Abstract
MicroRNAs (miRNAs) are small non-coding RNAs that function as part of RNA-induced silencing complexes that repress the expression of target genes. Over the past few years, miRNAs have been found to mediate complex regulation of a wide variety of mammalian viral infections, including Hepatitis C virus (HCV) infection. Here, we focus on a highly abundant, liver-specific miRNA, miR-122. In a unique and unusual interaction, miR-122 binds to two sites in the 5' untranslated region (UTR) of the HCV genome and promotes viral RNA accumulation. We will discuss what has been learned about this important interaction to date, provide insights into how miR-122 is able to modulate HCV RNA accumulation, and how miR-122 might be exploited for antiviral intervention.

Abstract
Dramatic improvements in short-term graft outcomes after solid organ transplantation over the past decade have not translated into major improvements in long-term allograft acceptance and patient survival. Innovative approaches to develop individualized therapy for the graft recipient are critically needed and have stimulated active research in the field of biomarker discovery. MicroRNAs (miRNAs) are small non-coding RNAs that function as important regulators of gene and protein expression by RNA interference. They are implicated in many biological processes and diseases. Their characteristics prompted their evaluation as candidate molecular markers to evaluate the transplant patient: their expression profile is specifically altered in pathological conditions, they can be easily detected and quantified in tissues, and they are highly stable in almost all body fluids, allowing the development of non-invasive approaches. We aimed to review the existing knowledge about miRNA biogenesis and function and summarize the recent findings demonstrating their potential use as biomarkers in solid organ transplantation. Although they still need to be validated in larger patient cohorts, miRNAs are not far from being used in transplant clinical practice as usefulness biomarkers. Ongoing multi-center trials should help to further define the clinical utility of miRNA profiles as biomarkers of allograft status and outcome.
