Abstract
BACKGROUND Polycystic Ovary Syndrome (PCOS) is a major cause of anovulatory infertility. Some studies showed that miRNAs were used as diagnostic/prognostic biomarkers for various diseases. OBJECTIVE To identify candidate miRNAs in Granulosa Cells (GCs) of PCOS and evaluate their potential values for PCOS diagnosis. METHODS We screened differentially expressed miRNAs in GCs between PCOS and controls by the microarray data from the GEO database. GCs were collected from 21 controls and 24 PCOS. The candidate miRNAs were verified by qRT-PCR. The correlation was investigated between candidate miRNAs and clinical characteristics in participants. Diagnostic value of candidate miRNAs was analyzed by receiver operating characteristic (ROC) curve. RESULTS Seven miRNAs were differentially expressed in PCOS compared with controls. Furthermore, the validation results demonstrated that hsa-miR-3188 and hsa-miR-3135b showed higher levels in GCs with PCOS patients (p< 0.05). In addition, the expressions of hsa-miR-3188 and hsa-miR-3135b were negative correlated with FSH and hsa-miR-3188 was positive correlated with BMI (p< 0.05). ROC analysis indicated that hsa-miR-3188 and hsa-miR-3135b could differentiate PCOS from controls, and the hsa-miR-3188/3135b improved the predictive accuracy for PCOS. CONCLUSIONS The expressions of hsa-miR-3188 and hsa-miR-3135b in human GCs were significantly associated with PCOS. Moreover, the hsa-miR-3188/3135b has certain diagnostic value for distinguishing PCOS.

Abstract
Background Occult hepatitis B virus infection (OBI) is an important risk factor of liver cirrhosis and hepatocellular carcinoma. Type 1 interferon (IFN) signaling-related miRNAs were significantly associated with hepatitis B virus (HBV) infection. However, the characteristics of serum IFN signaling-related miRNAs in OBI remain unclear. Therefore, this study aimed to analyze the expression levels of serum IFN signaling-related miRNAs in OBI and to evaluate their potential values for OBI diagnosis. Methods Twenty serum samples for training test (10 healthy controls and 10 OBI patients) and 438 validation serum samples from healthy controls, asymptomatic HBsAg carriers (ASC), and chronic hepatitis B (CHB) and OBI patients were collected. Expression levels of 32 IFN signaling-related miRNAs were analyzed in training and validation sets of samples using RT-qPCR. Results Among 32 IFN signaling-related miRNAs, decreased miR-122 levels and increased miR-130a levels were detected in training OBI samples. Furthermore, the results from validation test showed that the mean serum miR-122 and miR-130a level was 2.28 ± 0.96 and 3.11 ± 0.93 in OBI subjects, respectively. Compared to the healthy controls, ASC and CHB patients, miR-122 levels were significantly downregulated, while miR-130a levels were significantly upregulated in OBI patients. ROC analysis indicated that miR-122 + miR-130a could differentiate OBI from healthy controls, ASC, and CHB (≥ 0.87 of AUC). Conclusions Our study suggested that decreased serum miR-122 level and increased miR-130a level were significantly associated with OBI. Moreover, a combination of miR-122 and miR-130a could be served as a potential marker for OBI diagnosis.

Abstract
PURPOSE Acetaminophen-induced liver injury (APAP) is recognized as a frequent etiologic factor responsible for hepatic damage in the developed world. Management remains still elusive as treatment options are limited and their results are inconclusive. Consequently new strategies are explored at the experimental level. Mesenchymal stem cells (MSCs) present a promising modality as they can promote liver regeneration (LG) and compensate acute liver injury (ALI). MATERIALS AND METHODS Our research was focused on articles related to drug-induced liver injury, mechanisms of liver regeneration (LG) after Acute Liver Injury (ALI) and recent experimental protocols of Mesenchymal Stem Cells (MSCs) transplantation after chemical insult. All these studies are cited on Pubmed and MedLine. RESULTS This review has three distinct sections. First recent developments in ALI pathogenesis are presented. The second section covers cellular pathways and histological findings relevant to liver regeneration. The final chapter analyzes MSCs transplantation protocols after ALI and interrelation between liver regeneration and hepatic differentiation of MSCs. CONCLUSION Adipose tissue stem cells (ADSCs) and (MSCs) transplantation represents a promising modality in severe ALI management although many aspects remain to be clarified.

Abstract
Data discussed in recent reviews demonstrated that dysregulation of microRNA (miRNA) expression profiles occurs during cervical carcinogenesis and characteristic up- or downregulation of certain miRNAs might be used as biomarkers. The majority of altered miRNAs, however were found to be inconsistent upon comparison with cancerous and normal cervical epithelia in the discussed studies due to several reasons. The results obtained in this present review suggest the need for further investigations on miRNAs on larger sample sizes in order to indicate sensitivity and specificity by means of well defined, "unified" methods. In addition, obtaining further data on the clinical course and outcome of patients in comparison to the dysregulation of miRNA expression profile could turn miRNAs into prognostic and/or progression markers. Inhibition of overexpressed miRNAs, as suggested by some authors, might even serve as target for cancer therapy.

Abstract
BACKGROUND AND AIM Management of hepatitis C virus (HCV) recurrence is a major challenge after liver transplantation. Significant dysregulated expression of HCV receptors (i.e. claudin-1, occludin, tetraspanin CD81, scavenger receptor type B1) has been shown recently during HCV infection. This might facilitate hepatocytic entry and reinfection of HCV. MicroRNAs (miRs) play role in the regulation of gene expression. We aimed to characterize miR expression profiles related to HCV infection and antiviral therapy in adult liver transplant recipients, with special emphasis on miRs predicted to target HCV receptors. METHODS Twenty-eight adult liver transplant recipients were enrolled in the study. Paired biopsies were obtained at the time of HCV recurrence and at the end of antiviral treatment. MiRs for HCV receptors were selected using target prediction software. Expression levels of miR-21, miR-23a miR-34a, miR-96, miR-99a*, miR-122, miR-125b, miR-181a-2*, miR-194, miR-195, miR-217, miR-221, and miR-224 were determined by reverse transcription-quantitative polymerase chain reaction. RESULTS miR-99a* and miR-224 expressions were increased in HCV recurrence samples, while miR-21 and miR-194 were decreased in comparison to normal liver tissue. Increased expressions of miR-221, miR-224, and miR-217 were observed in samples taken after antiviral therapy when compared with HCV recurrence samples. High HCV titer at recurrence was associated with higher level of miR-122. CONCLUSIONS Samples at recurrence of HCV and after antiviral therapy revealed distinct HCV-related miR expression profiles, with significant dysregulation of those miRNAs potentially targeting mRNAs of HCV receptors. In particular, miR-194 and miR-21 might be involved in the regulation of HCV receptor proteins' expression during HCV infection and antiviral therapy.

Abstract
The details of molecular alterations occurring during hepatocarcinogenesis have not been revealed yet. Nevertheless, it is known that microRNAs (miRNA), these short RNA molecules regulating gene expression mainly in a negative way, are also involved in this process. Altered miRNA expression levels are present in liver diseases when compared with normal liver tissue, and the observed alterations depend mainly on which is more advantegous for the disease: activation or inhibition of the genes (e.g. oncogenes or tumor suppressor genes) regulated by the altered miRNAs. The miRNA expression pattern described in hepatocellular carcinoma seems to differ the most from that found in the normal liver; however, remarkable alterations at miRNA levels have been published in early stages of hepatic tumor progression such as fibrosis and chronic hepatitis. For example, the expression of miR-21, miR-221, miR-222 and miR-199a showing characteristic alterations in hepatocellular carcinoma also displayed deregulated expressions in these two early stages. The liver characteristic miRNA, miR-122, usually exhibits a decreased expression level upon liver injury as well as miR-122 expression tends to decrease as hepatic carcinogenesis progresses. Besides, miR-122 enhances the replication of hepatitis C virus and the initial low or high level of miR-122 seems to influence the efficiency of interferon therapy. Recently, statistically significant differences have been detected in the expression of several miRNAs being present in the serum of patients with chronic hepatitis, chirrhosis and hepatocellular carcinoma when compared with normal controls. It suggests that serum miRNAs could be potential biomarkers. In this article, the major and recent alterations of microRNA expression patterns in stages of hepatocarcinogenesis such as fibrosis, viral infections (hepatitis), cirrhosis and hepatocellular carcinoma are summarized.
