Abstract
The hepatitis C virus (HCV) infection affects 58 million people worldwide. In the United States, the incidence rate of acute hepatitis C has doubled since 2014; during 2021, this increased to 5% from 2020. Acute hepatitis C is defined by any symptom of acute viral hepatitis plus either jaundice or elevated serum alanine aminotransferase (ALT) activity with the detection of HCV RNA, the anti-HCV antibody, or hepatitis C virus antigen(s). However, most patients with acute infection are asymptomatic. In addition, ALT activity and HCV RNA levels can fluctuate, and a delayed detection of the anti-HCV antibody can occur among some immunocompromised persons with HCV infection. The detection of specific biomarkers can be of great value in the early detection of HCV infection at an asymptomatic stage. The high rate of HCV replication (which is approximately 1010 to 1012 virions per day) and the lack of proofreading by the viral RNA polymerase leads to enormous genetic diversity, creating a major challenge for the host immune response. This broad genetic diversity contributes to the likelihood of developing chronic infection, thus leading to the development of cirrhosis and liver cancer. Direct-acting antiviral (DAA) therapies for HCV infection are highly effective with a cure rate of up to 99%. At the same time, many patients with HCV infection are unaware of their infection status because of the mostly asymptomatic nature of hepatitis C, so they remain undiagnosed until the liver damage has advanced. Molecular mechanisms induced by HCV have been intensely investigated to find biomarkers for diagnosing the acute and chronic phases of the infection. However, there are no clinically verified biomarkers for patients with hepatitis C. In this review, we discuss the biomarkers that can differentiate acute from chronic hepatitis C, and we summarize the current state of the literature on the useful biomarkers that are detectable during acute and chronic HCV infection, liver fibrosis/cirrhosis, and hepatocellular carcinoma (HCC).

Global blood miRNA profiling unravels early signatures of immunogenicity of Ebola vaccine rVSVΔG-ZEBOV-GP. iScience 2023; 26:108574. [PMID: 38162033 PMCID: PMC10755791 DOI: 10.1016/j.isci.2023.108574] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Revised: 10/27/2023] [Accepted: 11/21/2023] [Indexed: 01/03/2024] Open
Abstract
The vectored Ebola vaccine rVSVΔG-ZEBOV-GP elicits protection against Ebola Virus Disease (EVD). In a study of forty-eight healthy adult volunteers who received either the rVSVΔG-ZEBOV-GP vaccine or placebo, we profiled intracellular microRNAs (miRNAs) from whole blood cells (WB) and circulating miRNAs from serum-derived extracellular vesicles (EV) at baseline and longitudinally following vaccination. Further, we identified early miRNA signatures associated with ZEBOV-specific IgG antibody responses at baseline and up to one year post-vaccination, and pinpointed target mRNA transcripts and pathways correlated to miRNAs whose expression was altered after vaccination by using systems biology approaches. Several miRNAs were differentially expressed (DE) and miRNA signatures predicted high or low IgG ZEBOV-specific antibody levels with high classification performance. The top miRNA discriminators were WB-miR-6810, EV-miR-7151-3p, and EV-miR-4426. An eight-miRNA antibody predictive signature was associated with immune-related target mRNAs and pathways. These findings provide valuable insights into early blood biomarkers associated with rVSVΔG-ZEBOV-GP vaccine-induced IgG antibody responses.

Micro-Players of Great Significance-Host microRNA Signature in Viral Infections in Humans and Animals. Int J Mol Sci 2022; 23:ijms231810536. [PMID: 36142450 PMCID: PMC9504570 DOI: 10.3390/ijms231810536] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2022] [Revised: 09/04/2022] [Accepted: 09/08/2022] [Indexed: 11/22/2022] Open
Abstract
Over time, more and more is becoming known about micro-players of great significance. This is particularly the case for microRNAs (miRNAs; miR), which have been found to participate in the regulation of many physiological and pathological processes in both humans and animals. One such process is viral infection in humans and animals, in which the host miRNAs—alone or in conjunction with the virus—interact on two levels: viruses may regulate the host’s miRNAs to evade its immune system, while the host miRNAs can play anti- or pro-viral roles. The purpose of this comprehensive review is to present the key miRNAs involved in viral infections in humans and animals. We summarize the data in the available literature, indicating that the signature miRNAs in human viral infections mainly include 12 miRNAs (i.e., miR-155, miR-223, miR-146a, miR-122, miR-125b, miR-132, miR-34a, miR -21, miR-16, miR-181 family, let-7 family, and miR-10a), while 10 miRNAs are commonly found in animals (i.e., miR-155, miR-223, miR-146a, miR-145, miR-21, miR-15a/miR-16 cluster, miR-181 family, let-7 family, and miR-122) in this context. Knowledge of which miRNAs are involved in different viral infections and the biological functions that they play can help in understanding the pathogenesis of viral diseases, facilitating the future development of therapeutic agents for both humans and animals.

Abstract
Micro RNAs (miRNAs) are essential players in HIV and HCV infections, as both viruses modulate cellular miRNAs and interact with the miRNA-mediated host response. We aim to analyze the miRNA profile of HIV patients with different exposure to HCV to explore specific signatures in the miRNA profile of PBMCs for each type of infection. We massively sequenced small RNAs of PBMCs from 117 HIV+ infected patients: 45 HIV+ patients chronically infected with HCV (HIV/HCV+), 36 HIV+ that spontaneously clarified HCV after acute infection (HIV/HCV-) and 36 HIV+ patients without previous HCV infection (HIV). Thirty-two healthy patients were used as healthy controls (HC). Differential expression analysis showed significantly differentially expressed (SDE) miRNAs in HIV/HCV+ (n = 153), HIV/HCV- (n = 169) and HIV (n = 153) patients. We found putative dysregulated pathways, such as infectious-related and PI3K signaling pathways, common in all contrasts. Specifically, putatively targeted genes involved in antifolate resistance (HIV/HV+), cancer-related pathways (HIV/HCV-) and HIF-signaling (HIV) were identified, among others. Our findings revealed that HCV strongly influences the expression profile of PBMCs from HIV patients through the disruption of its miRNome. Thus, different HCV exposure can be identified by specific miRNA signatures in PBMCs.

CRNDE-h transcript/miR-136-5p axis regulates interleukin enhancer binding factor 2 expression to promote hepatocellular carcinoma cell proliferation. Life Sci 2021; 284:119708. [PMID: 34153299 DOI: 10.1016/j.lfs.2021.119708] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Revised: 05/27/2021] [Accepted: 06/02/2021] [Indexed: 12/12/2022]
Abstract
AIMS Hepatocellular carcinoma (HCC) is a primary malignancy of the hepatocyte. Interleukin enhancer binding factor 2 (ILF2) plays a role in the development of HCC. However, the regulatory mechanisms of ILF2 expression in HCC remain unclear. In this study, we aimed to identify ILF2-targeting microRNAs (miRNAs) and to explore how they affect ILF2 expression in HCC. MAIN METHODS The tissue specimens were collected from 25 HCC patients. The underlying regulatory mechanism of ILF2 expression in HCC progression was determined using luciferase reporter assay, quantitative real-time PCR, Western blotting, and BrdU incorporation assay. KEY FINDINGS Of predicted miRNA candidates (miR-122-5p, miR-425-5p, miR-136-5p, miR-7-5p, miR-421 and miR-543), a statistically significant inverse correlation by linear correlation analysis was observed between miR-136-5p and ILF2 mRNA expressions in patients with HCC (r = -0.627, P < 0.001). Further analysis demonstrated that ILF2 was directly regulated by miR-136-5p. In addition, we showed that long noncoding RNA colorectal neoplasia differentially expressed-h (lncRNA CRNDE-h) transcript expression was significantly up-regulated in HCC, and a miR-136-5p binding site was newly found in the lncRNA CRNDE-h transcript sequence using IntaRNA tool. In terms of mechanism, highly-expressed lncRNA CRNDE-h transcript can sponge miR-136-5p, thereby preventing it from interacting with target ILF2 mRNA while promoting the proliferation of HCC cells. SIGNIFICANCE The lncRNA CRNDE-h/miR-136-5p/ILF2 axis plays a significant regulatory role in HCC progression, which may partly explain the pathogenic mechanisms of HCC and may provide promising potential targets for the diagnosis, treatment, and prognosis of HCC.

Abstract
Background Gestational diabetes mellitus (GDM) seriously affects the health of mothers and infants. The high-glucose-induced inhibition in trophoblast cell viability is an important event in GDM pathogenesis. This study evaluated the expression and clinical significance of miR-136 in GDM patients, and the biological function and related mechanisms of miR-136 in the regulation of trophoblast cell proliferation were explored. Methods The expression of miR-136 in serum and placenta of GDM patients was measured using quantitative Real-Time PCR. Trophoblast cells were stimulated with high-glucose medium to mimic the pathological changes of GDM, and the effect of miR-136 was examined by CCK-8 assay. A luciferase reporter assay was used to confirm the target gene of miR-136, and the relationship of E2F transcription factor 1 (E2F1) with miR-136 in GDM was further analyzed. Results miR-136 expression was significantly elevated in GDM serum and tissue samples. By high-glucose treatment, trophoblast cell proliferation was inhibited and miR-136 expression was promoted. The knockdown of miR-136 could promote the proliferation of trophoblast cells exposed to high glucose, whereas the overexpression of miR-136 could suppress it. In addition, E2F1 was identified as a target gene of miR-136, which could mediate the regulatory effect of miR-136 on trophoblast cell proliferation. Conclusion Collectively, miR-136 expression is increased in both serum and placental tissues in GDM patients, and miR-136 mediates the inhibiting effect of high glucose on trophoblast cell viability by targeting E2F1.

Abstract
Exosomes seem to play an important role in hepatits C virus (HCV) and hepatitis E virus (HEV) infection by shielding their cargo from the host immune responses, with microRNAs being key exosomal components. Little is known about their involvement in a mixed HCV/HEV infection or at the early stages of infection, such as in asymptomatic blood donors (BDs). To obtain preliminary data, we have compared the exosomal microRNA expression profiles in four each of HCV RNA-positive, HEV RNA-positive and negative blood donors and four patients, one of whom was a rare patient with HCV/HEV co-infection. Exosomes were purified from sera by a combination of a precipitation and density gradient centrifugation and exosomal microRNA was analysed using Taqman array cards. Out of 33 deregulated miRNAs, miR-885-5p and miR-365 were upregulated in HCV BDs, miR-627-5p was downregulated in HCV BD and miR-221 was downregulated in HCV patients and BDs. In HEV infection, miR-526b appeared specifically downregulated. Six miRNAs (miR-628-3p, miR-194, miR-151-3p, miR-512-3p, miR-335 and miR-590) indicated a potential involvement in both infections. First time preliminary data on pre- and post-antiviral treatment exosomal microRNA profiles of the HEV/HCV co-infected patient revealed a pool of 77 upregulated and 43 downregulated miRNAs to be further investigated for their potential roles in these viral infections.

Abstract
This study was aimed to investigate the potential regulatory mechanism of high-content hydrogen water (HHW) in non-alcoholic fatty liver disease (NAFLD). A high-fat diet (HFD)-induced NAFLD mice model and cellular model were prepared. The serum levels of alanine transaminase (ALT), aspartate transaminase (AST), total cholesterol (TCH) and triglycerides (TG) were measured. The expression levels of representative five microRNA (miRNAs) (miR-103, miR-488, miR-136, miR-505 and miR-148a) in liver tissues were determined by quantitative real-time PCR (qRT-PCR). The target of miR-136 was validated by RNA immunoprecipitation (RIP) and pull-down assay. MiR-136, MEG3 and nuclear factor erythroid 2-related factor 2 (Nrf2) expression levels following cell treatment were detected in hepatocytes using qRT-PCR and Western blotting. Moreover, cell viability and TG content were conducted. MiR-136 was downregulated, MEG3 as well as Nrf2 was upregulated and serum lipid level was reduced in NAFLD mice model after HHW treatment, which exerted the same effect in cellular model. RIP and RNA pull-down assay confirmed that MEG2 was a downstream target of miR-136. What's more, HHW ameliorated lipid accumulation by regulating miR-136/MEG3/Nrf2 axis in vitro and in vivo. Hence, HHW alleviated NAFLD by downregulation of miR-136 through mediating Nrf2 via targeting MEG3.

Abstract
BACKGROUND & AIMS Hepatitis C virus (HCV) infection is known to cause major alterations in the cross-talk between hepatic and immune cells thus contributing to the liver disease pathogenesis. Extracellular vesicles have been proved to act as major players in cell-cell communication, and their cargo changes in relation to pathophysiological states. The aim of this study was to evaluate the effects of chronic HCV infection and direct-acting antivirals (DAA) on exosome-delivered microRNAs and on their ability to modulate the innate immune response. METHODS Exosomes isolated from the plasma of healthy donors and naïve, viremic HCV patients before and after DAA treatment have been compared for their microRNAs cargo by quantitative polymerase chain reaction. Functional assays with peripheral blood cells from healthy donors were performed to assess exosome-mediated immune responses. RESULTS MicroRNAs associated with HCV-related immunopathogenesis which were found to be enriched in exosomes of HCV viremic patients (in particular, miR-122-5p, miR-222-3p, miR-146a, miR-150-5p, miR-30c, miR-378a-3p and miR-20a-5p) were markedly reduced by DAA therapy. This exosome-microRNA cargo modulation parallels changes in their immunomodulatory properties in ex vivo experiments. Exosomes from HCV patients inhibit NK degranulation activity and this effect correlates with miR-122-5p or miR-222-3p levels. CONCLUSIONS Enrichment of immunomodulatory microRNAs in exosomes of HCV patients was correlated with their inhibitory activity on innate immune cells function. Direct-acting antivirals (DAA) treatment was observed to revert both microRNA content and functional profiles of systemic exosomes towards those of healthy donors. Exosome-associated microRNAs may provide valuable biomarkers to monitor immune response recovery.

Abstract
Osteoarthritis is the most frequent chronic bone and joint diseases in older populations all over the world. Lipopolysaccharide (LPS)-induced murine chondrogenic ATDC5 cell model has been widely used for testing new osteoarthritis therapeutic targets. This study aimed to explore the effects of microRNA-136 (miR-136) on LPS-induced ATDC5 cell injury and inflammatory cytokine expression, as well as underlying potential mechanism. We found that LPS remarkably inhibited ATDC5 cell viability, induced ATDC5 cell apoptosis, and upregulated the expression of inflammatory cytokines, including interleukin 1β (IL-1β), IL-6, IL-8, and tumor necrosis factor α (TNF-α; P < .01 or < .001). Moreover, LPS obviously upregulated the expression of miR-136 in ATDC5 cells (P < .05). Overexpression of miR-136 markedly exacerbated the LPS-induced ATDC5 cell viability inhibition, cell apoptosis enhancement, and inflammatory cytokine expression (P < .05), and suppression of miR-136 had opposite effects (P < .05). Myeloid cell leukemia 1 (Mcl-1) was a direct target gene of miR-136, which participated in the effect of miR-136 on LPS-induced ATDC5 cell inflammatory injury. Overexpression of Mcl-1 alleviated the LPS-induced inactivation of Wnt/β-catenin and Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathways, while suppression of Mcl-1 had opposite effects. To conclude, this study verified that miR-136 promoted LPS-induced ATDC5 cell injury and inflammatory cytokine expression by targeting Mcl-1, and Mcl-1 was involved in the regulatory effects of LPS on Wnt/β-catenin and JAK/STAT signaling pathways in ATDC5 cells.

Abstract
AIM Hepatocellular carcinoma (HCC) is a common outcome of chronic hepatitis C virus (HCV) infection and constitutes the main burden of this disease. The molecular mechanisms underlying the development of HCC are multiple and might involve certain microRNA (miR). As discordant results have been reported concerning the detection of expression of miR-152 and miR-122 in HCC, our aim was to measure the levels of both miRs in serum and liver samples. METHODS We analyzed miR-152 and miR-122 expression by reverse transcription-quantitative polymerase chain reaction in a serum cohort from 14 HCV-infected patients who developed HCC, 20 HCV+ patients without HCC, and 19 control patients. We also studied miR-152 and miR-122 in an independent tissue cohort from 11 normal livers, and from paired HCC and non-tumor adjacent livers of 11 HCV-infected patients and 12 non-infected patients. RESULTS In serum samples, higher levels of miR-122 were found in non-HCC HCV+ compared to HCC HCV+ and control groups, whereas miR-152 was detectable in a lower range in HCC HCV+ compared to non-HCC HCV+ and control groups. We found higher signals for miR-122 and miR-152 in non-tumor liver and HCC tissues compared to control tissues. Hepatocellular carcinoma etiology had no detectable influence on miR-122 expression, whereas miR-152 was increased in HCV+ tissue samples. CONCLUSIONS Detection of low values of circulating miR-152 is a potentially interesting marker of hepatocarcinogenesis in HCV+ patients, in contrast to miR-122, which varies according to hepatocyte damage.

Abstract
Early diagnosis of hepatocellular carcinoma (HCC) can significantly improve the overall survival of HCC patients. However, current diagnostic markers are compromised and limited by their low sensitivity and specificity. In this work, circulating microRNAs (miRs) were utilized as a diagnostic tool to test their efficiency to segregate HCC and hepatitis C virus (HCV)-infected patients from healthy subjects. Nine HCC-related miRs (miR-21, miR-30c, miR-93, miR-122, miR-125b, miR-126, miR-130a, miR-193b and miR-222) were analyzed by Real-Time PCR in 86 serum samples; 34 HCC and 52 HCV patients in addition to 25 healthy subjects. The sensitivity and specificity of these miRs were assessed. Our results demonstrated that the median serum level of seven miRs was significantly reduced (P ranges from <0.01 to<0.001) in HCC patients whereas nine miRs were reduced (P<0.001) in HCV compared to healthy controls. Receiver operating characteristic (ROC) curve analyses had shown high diagnostic accuracy (AUC=1.0) when seven and nine combined miRs were considered in HCC and HCV groups, respectively compared to their counterparts. However, a combination of differentially expressed miRs did not improve the discriminatory power (AUC=0.742) when HCC compared to non-HCC groups. miR-122 showed the highest sensitivity and specificity to stratify HCC and HCV versus normal individuals and HCC versus HCV patients. We conclude that differentially expressed miRs in the serum of HCV and HCC patients can be utilized as surrogate and non-invasive biomarker for segregation of HCV and HCC patients from healthy subjects.

Abstract
The clinical significance of microRNA (miR)‑136‑5p in hepatocellular carcinoma (HCC) has not been verified. Therefore, in the current study, the authors aimed to explore miR‑136‑5p expression and its clinical significance in HCC, as well as to investigate its potential target genes function. The authors detected the levels of miR‑136‑5p in 101 pairs of HCC and para‑cancer tissues via reverse transcription‑quantitative polymerase chain reaction. Gene Expression Omnibus database and the Cancer Genome Atlas (TCGA) database were used to further verify the clinical significance of miR‑136‑5p expression in HCC. The target genes prediction analysis of miR‑136‑5p, natural language processing (NLP) analysis of HCC in PubMed and gene functional enrichment analysis were conducted. The miR‑136‑5p level was markedly downregulated in HCC tissue, compared to para‑non‑tumor tissue. MiR‑136‑5p expression decreased in HCC patients with metastasis (P=0.004), advance TNM stage (P<0.001), portal vein tumor embolus (P=0.007) and vaso‑invasion (P=0.003), compared with those HCC patients with non‑metastasis, early TNM stage, non‑portal vein tumor embolus and non‑vaso‑invasion, respectively. In the TCGA database, downregulated miR‑136‑5p was also observed in HCC tissue compared to normal liver tissue (P<0.001). There were 178 genes obtained from the overlap between predicted targets and NLP analysis. GO and KEGG pathway analyses revealed some significant pathways related to cancers. Downregulation of miR‑136‑5p may be responsible for the carcinogenesis and aggressiveness of HCC. miR‑136‑5p may act as an anti‑carcinoma miRNA, which is essential for HCC progression through the regulation of various signaling pathways. Thus, miR‑136‑5p interaction may provide a novel strategy for HCC treatment.

Abstract
Accurate staging of liver fibrosis is important for clinical decision making and personalized management. Liver fibrosis is influenced by patients' genomics, including IFNL3 genotype and microRNA expression. However, incorporating microRNAs into fibrosis prediction algorithms has not been investigated. We examined the potential of eight selected serum microRNAs; miR-122, miR-126, miR-129, miR-199a, miR-155, miR-203a, miR-221, and miR-223 as non-invasive biomarkers to stage liver fibrosis in HCV-associated chronic liver disease (HCV-CLD). 145 Egyptian HCV-CLD patients were divided according to Metavir fibrosis scores. MicroRNAs and IFNL3 rs12979860 genotype were assayed by RT-qPCR and allelic discrimination techniques, respectively. Serum miR-122 was downregulated, whereas miR-203a and miR-223 were upregulated in significant fibrosis (≥F2) compared with no/mild fibrosis (F0-F1). Serum miR-126, miR-129, miR-203a, and miR-223 were upregulated in severe fibrosis (≥F3) and cirrhosis (F4) compared with F0-F2 and F0-F3, respectively. miR-221 was upregulated in ≥F3, but unchanged in F4. miR-155, miR-199a, and IFNL3 rs12979860 genotype were not significantly different in all comparisons. Differentially expressed serum microRNAs discriminated ≥F2, ≥F3, and F4 by receiver-operating-characteristic analysis. Multivariate logistic analysis revealed a model combining miR-129, miR-223, AST, and platelet count with high diagnostic accuracy for ≥F3 (AUC=0.91). The model also discriminated F4 (AUC=0.96) and ≥F2 (AUC=0.783), and was superior to APRI and FIB-4 in discriminating ≥F3 and F4, but not ≥F2. In conclusion, combining serum microRNAs with baseline predictors could serve as a new non-invasive algorithm for staging HCV-associated liver fibrosis. Additional studies are required to confirm this model and test its significance in liver fibrosis of other etiologies.

Abstract
Early allograft dysfunction (EAD) after liver transplantation (LT) is associated with inferior graft survival. EAD is more prevalent in grafts from donation after circulatory death (DCD). However, accurate prediction of liver function remains difficult because of the lack of specific biomarkers. Recent experimental and clinical studies highlight the potential of hepatocyte-derived microRNAs (miRNAs) as sensitive, stable, and specific biomarkers of liver injury. The aim of this study was to determine whether miRNAs in graft preservation fluid are predictive for EAD after clinical LT and in an experimental DCD model. Graft preservation solutions of 83 liver grafts at the end of cold ischemia were analyzed for miRNAs by reverse transcription polymerase chain reaction. Of these grafts, 42% developed EAD after transplantation. Results were verified in pig livers (n = 36) exposed to different lengths of warm ischemia time (WIT). The absolute miR-122 levels and miR-122/miR-222 ratios in preservation fluids were significantly higher in DCD grafts (P = 0.001) and grafts developing EAD (P = 0.004). In concordance, the miR-122/miR-222 ratios in perfusion fluid correlate with serum transaminase levels within the first 24 hours after transplantation. Longterm graft survival was significantly diminished in grafts with high miR-122/miR-222 ratios (P = 0.02). In the porcine DCD model, increased WIT lead to higher absolute miR-122 levels and relative miR-122/miR-222 ratios in graft perfusion fluid (P = 0.01 and P = 0.02, respectively). High miR-122/miR-222 ratios in pig livers were also associated with high aspartate aminotransferase levels after warm oxygenated reperfusion. In conclusion, both absolute and relative miR-122 levels in graft preservation solution are associated with DCD, EAD, and early graft loss after LT. As shown in a porcine DCD model, miRNA release correlated with the length of WITs. Liver Transplantation 23 946-956 2017 AASLD.

Abstract
Inflammatory bowel disease (IBD) is difficult to diagnose due to nonspecific and variable symptoms, and lack of reliable diagnostic tests. Current methods are invasive, non-sensitive, non-predictive, and do not easily discriminate between its two main forms. Consequently, there remains a great need for reliable serum markers for IBD. Here, using a longitudinal study of various mouse models of colitis, we identified a serum miRNA signature that indicated the development of colitis and discriminated between inflammations of various origins (colitis from arthritis). Unlike the existing biomarkers, the newly identified signature also serves to distinguish individuals at risk, predict the type of inflammation, and evaluate the response to therapeutics. Moreover, the miRNA signature identified in mice predicted ulcerative colitis with 83.3% accuracy. In future, the signature identified herein could play a central role in monitoring inflammatory disorders and therapeutic responses in patients, thereby paving the way for personalized medicine.

Parallel expression profiling of hepatic and serum microRNA-122 associated with clinical features and treatment responses in chronic hepatitis C patients. Sci Rep 2016; 6:21510.

Abstract
MicroRNAs (miRNAs) are small, non-coding RNAs that regulate a variety of biological processes. Recently, human liver-specific miRNA miR-122 has been reported to facilitate hepatitis C virus (HCV) replication in liver cells. HCV is one of the leading causes of liver diseases worldwide. In Pakistan, the estimated prevalence is up to 10%. Here, we report hepatic and serum miR-122 expression profiling from paired liver and serum samples from treatment-naive chronic hepatitis C (CHC) patients and controls. We aimed to elucidate the biomarker potential of serum miR-122 for monitoring disease progression and predicting end treatment response (ETR). Hepatic miR-122 levels were significantly down-regulated in CHC patients. A significant inverse correlation was observed between hepatic and serum miR-122 levels, indicating that serum miR-122 levels reflect HCV-associated disease progression. Both hepatic and serum miR-122 were significantly correlated (P < 0.05) with several clinicopathological features of CHC. Receiver operator curve analysis showed that serum miR-122 had superior discriminatory ability even in patients with normal alanine transaminase levels. Multivariate logistic regression analysis highlighted pre-treatment serum miR-122 levels as independent predictors of ETR. In conclusion, serum miR-122 holds the potential to serve as a promising biomarker of disease progression and ETR in CHC patients.

Abstract
Hepatitis C virus (HCV) infection affects approximately 3 % of the world population. HCV targets hepatic tissue, and most infected patients develop a chronic infection. Currently, studies have demonstrated an association between HCV-RNA replication and miR-122, the most abundant microRNA in the liver. Our aim was to evaluate liver and serum expression of miR-122 in patients infected with HCV genotypes 1 and 3, and to identify possible associations between miR-122 expression and lipid profiles, HCV viral load, apolipoproteins and liver enzymes. MicroRNAs were isolated from blood and liver tissue, and miR-122 expression was quantified by real-time PCR. HCV viral load was quantified by real-time PCR and HCV genotype, and serum biomarkers were obtained from medical report. The levels of miR-122 were higher in liver than those in blood from individuals infected with HCV genotypes 1 and 3 (p < 0.0001). The tissue levels of miR-122 were higher in subjects infected with HCV genotype 3 (6.22-fold, p < 0.001). A positive correlation was observed between the blood and hepatic levels of miR-122 in patients infected with HCV genotype 1 (r = 0.302, p = 0.026); in these patients, an inverse correlation was observed between serum apolipoprotein A-II (ApoA-II) levels and the blood (r = -0.330; p = 0.014) and hepatic (r = -0.311; p = 0.020) levels of miR-122. In patients infected with HCV genotype 3, there was a positive correlation between the hepatic miR-122 and the high-density lipoprotein-HDL (r = 0.412, p = 0.036) and insulin (r = 0.478, p = 0.044). Lipid metabolism proteins and miR-122 expression levels have different relations in HCV-3- and HCV-1-infected patients.

Abstract
Hepatic fibrosis, which results from chronic liver disease, currently lacks effective treatment. MicroRNAs, a group of small noncoding RNA molecules, have been observed to play an essential role in liver diseases, including hepatic fibrosis. In this study, we described the regulation of nuclear factor kappa B (NF-κB) inhibitor alpha (IκBα) and its possible signaling pathway by miR-126 in human hepatic stellate cell (HSC) line LX-2. The 3'-untranslated region (3'-UTR) of IκBα combined with miR-126 was analyzed by using a dual-luciferase reporter assay. Furthermore, the effects of miR-126 on IκBα mRNA and protein and NF-κB protein expression were assessed by real-time quantitative reverse transcriptase-polymerase chain reaction (qRT-PCR) and western blot analysis in the human HSC LX-2 cell line transfected with miR-126 mimic or inhibitor. Moreover, to understand the molecular mechanism of miR-126 in promoting liver fibrosis through NF-κB signaling pathway, the NF-κB downstream signaling factors expression such as transforming growth factor (TGF)-β1 and collagen I mRNA were detected by real-time qRT-PCR. We identified that IκBα is a potential target gene of miR-126, by directly targeting its 3'-UTR. Endogenous miR-126 and exogenous miR-126 mimic inhibited IκBα expression. Moreover, overexpression of miR-126 reduced total and the cytoplasm IκBα protein expression and increased total and cytoblast NF-κB protein expression of LX-2. Conversely, knockdown of miR-126 could inhibit NF-κB activation by upregulation of IκBα protein expression. Further, miR-126 promoted TNF-a-induced TGF-β1 and collagen I mRNA expression in LX-2 cells. miR-126 may play an important role in hepatic fibrosis by downregulating the expression of IκBα partly through the NF-κB signaling pathway.

Abstract
Hepatitis C virus (HCV) is a global health burden with an estimated 170-200 million peoples chronically infected worldwide. HCV infection remains as an independent risk factor for chronic hepatitis, liver cirrhosis, hepatocellular carcinoma, and a major reason for liver transplantation. Discovery of direct acting antiviral (DAA) drugs have shown promising results with more than 90% success rate in clearing the HCV RNA in patients, although long-term consequences remain to be evaluated. microRNAs (miRNAs) are important players in establishment of HCV infection and target crucial host cellular factors needed for productive HCV replication and augmented cell growth. Altered expression of miRNAs is involved in the pathogenesis associated with HCV infection by controlling signaling pathways such as immune response, proliferation and apoptosis. miRNA is emerging as a means of communication between various cell types inside the liver. There is likely possibility of developing circulating miRNAs as biomarkers of disease progression and can also serve as diagnostic tool with potential of early therapeutic intervention in HCV associated end stage liver disease. This review focuses on recent studies highlighting the contribution of miRNAs in HCV life cycle and their coordinated regulation in HCV mediated liver disease progression.
