| Abstract: | ABSTRACT: The most common etiologic agents causing chronic hepatitis are hepatitis C and B viruses(HCV and HBV, respectively). Chronic infection caused by HCV is considered one of themajor causative agents of liver cirrhosis and hepatocellular carcinoma worldwide. Incombination with the increasing rate of new HCV infections, the lack of a current vaccineand/or an effective treatment for this virus continues to be a major public health challenge.The development of new treatments requires a better understanding of the virus and itsinteraction with the different components of the host cell. MicroRNAs (miRNAs) are smallnon-coding RNAs functioning as negative regulators of gene expression and represent aninteresting lead to study HCV infection and to identify new therapeutic targets. Until now,microRNA-122 (miR-122) and its implication in HCV infection have been the focus ofdifferent published studies and reviews. Here we will review recent advances in therelationship between HCV infection and miRNAs, showing that some of them emerge inpublications as challengers against the supremacy of miR-122. |
