AIMS Liver-enriched microRNA-122 (miR-122) is a novel circulating biomarker for drug-induced liver injury (DILI). To date, miR-122 has been measured in serum or plasma venous samples. If miR-122 could be measured in capillary blood obtained from a finger prick it would facilitate point-of-care testing, such as in resource-limited settings that have a high burden of DILI. METHODS In this study...

BACKGROUND Hepatitis C virus genotype 4 (HCV-4) infection is common in the Middle East and Africa, with an extraordinarily high prevalence in Egypt. MicroRNAs (miRNAs) play an important role in various diseases, including HCV infection. The aim of the present study was to assess serum miR-122, miR-221 and miR-21 expression profiles in HCV-4 patients prior to treatment with HCV-4 combination the...

Non-alcoholic fatty liver disease (NAFLD) covers a spectrum of diseases from simple steatosis to non-alcoholic steatohepatitis, with approximately 20% risk of progressing to fibrosis and cirrhosis. The aim of this study was to compare the relative expression levels of circulating miR-21, miR-34a, miR-122, miR-125b and miR-375 between healthy controls and NAFLD patients, and to assess the feasib...

miR-122 may function as a novel tumor suppressor. Expression of miR-122 could suppress the proliferation of multi-kinds of human cancer cell lines. In this work, expression of miR-122 via adenoviral vector in non-small-cell lung cancer (NSCLC) cells reduces the number of invasion and migration cells. miR-122 attenuates the epithelial-mesenchymal transition process, which mediates cancer cells m...

It has been demonstrated that microRNA-122 (miR-122) plays key roles in the modulation of hepatitis B virus (HBV) replication. This study examined the role of miR-122 in patients with hepatitis C virus (HCV)-HBV dual infection with active hepatitis C who received pegylated interferon-α and ribavirin dual therapy. We enrolled 121 patients with HCV-HBV dual infection after dual therapy. Stored se...

Using RNAhybrid software we found the predicted binding of complementary sequences between miR-122 and viral mRNAs, may be important for the antiviral effect of miR-122 on Borna disease virus (BDV). A moderate expression of miR-122 was identified in human oligodendroglial cells (OL), but with a much lower level of miR-122 in BDV persistent infection (OL/BDV) and cells transfected with BDV gene ...

microRNAs (miRNAs) are short, non-coding RNAs with post-transcriptional regulatory functions that participate in diverse biological pathways. miR-122, a liver-specific miRNA, has been found to be down-regulated in hepatocellular carcinoma (HCC) and HCC-derived cell lines. In this study, miR-122 was down-regulated in the hepatitis B virus (HBV)-related HCC cell line HepG2.2.15 compared to HepG2....

BACKGROUND Expression of miR-122 is highly specific to hepatocytes of the liver.  This miRNA is involved in lipid hemostasis of the tissue; however, there is no comprehensive understanding of its function in lipid hemostasis. MATERIALS AND METHODS Since hepatocytes are responsible for part of Triacylglycerol (TAG) synthesis in the body, we hypothesized that miR-122, as the most abundant miRNA...

MicroRNA 122 (miR-122) is highly expressed in the liver where it influences diverse biological processes and pathways, including hepatitis C virus replication and metabolism of iron and cholesterol. It is processed from a long non-coding primary transcript (~7.5 kb) and the gene has two evolutionarily-conserved regions containing the pri-mir-122 promoter and pre-mir-122 hairpin region. Several ...

microRNA-122 (miR-122) was one of the first examples of a tissue-specific miRNA. It is highly expressed in liver, where it constitutes 70% of the total miRNA pool. miR-122 expression is specific to the vertebrate lineage, where the sequence of the mature miRNA is completely conserved. miR-122 is a target for extensive study due to its association with cholesterol metabolism and hepatocellular c...
