Liver-specific microRNA-122
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...
متن کاملModulation of GB virus B RNA abundance by microRNA-122: dependence on and escape from microRNA-122 restriction.
Hepatitis C virus (HCV) RNA forms an unusual interaction with human microRNA-122 (miR-122) that promotes viral RNA accumulation in cultured human liver cells and in the livers of infected chimpanzees. GB virus B (GBV-B) is a hepatotropic virus and close relative of HCV. Thus, GBV-B has been used as a surrogate system to study HCV amplification in cultured cells and in infected tamarins. It was ...
متن کاملRegulation of hepatitis C virus by microRNA-122.
Most metazoan miRNAs (microRNAs) bind to sites in the 3'-UTRs (untranslated regions) of mRNA targets and negatively regulate protein synthesis. The liver-specific miR-122, however, exerts a positive effect on HCV (hepatitis C virus) RNA levels by binding directly to a site in the 5'-UTR of the viral RNA. HCV translation and RNA stability are unaffected, and therefore miR-122 is likely to act at...
متن کاملTargeting microRNA-122 to Treat Hepatitis C Virus Infection
An important host factor for hepatitis C virus (HCV) is microRNA-122 (miR-122). miR-122 is a liver-specific member of a family of small, non-coding RNA molecules known as microRNAs that play major roles in the regulation of gene expression by direct interaction with RNA targets. miR-122 binds directly to two sites in the 5' untranslated region (UTR) of HCV RNA and positively regulates the viral...
متن کاملCirculating microRNA-122 as a potential biomarker for liver injury.
Liver-specific microRNA-122 (miR-122) is involved in the replication of hepatitis C virus (HCV) and its potential as a target for antiviral intervention was recently assessed. However, the use of circulating miR-122 in the evaluation of liver function has never been reported. In the present study, changes of serum miRNA levels were first evaluated in acute human hepatotoxicity due to paraquat e...
