Abstract：
:Hepatitis C virus (HCV) translation is mediated by a highly conserved internal ribosome entry site (IRES), mainly located at the 5'untranslatable region (5'UTR) of the viral genome. Viral protein synthesis clearly differs from that used by most cellular mRNAs, rendering the IRES an attractive target for novel antiviral compounds. The engineering of RNA compounds is an effective strategy for targeting conserved functional regions in viral RNA genomes. The present work analyses the anti-HCV potential of HH363-24, an in vitro selected molecule composed of a catalytic RNA cleaving domain with an extension at the 3' end that acts as aptamer for the viral 5'UTR. The engineered HH363-24 efficiently cleaved the HCV genome and bound to the essential IIId domain of the IRES region. This action interfered with the proper assembly of the translationally active ribosomal particles 48S and 80S, likely leading to effective inhibition of the IRES function in a hepatic cell line. HH363-24 also efficiently reduced HCV RNA levels up to 70% in a subgenomic replicon system. These findings provide new insights into the development of potential therapeutic strategies based on RNA molecules targeting genomic RNA structural domains and highlight the feasibility of generating novel engineered RNAs as potent antiviral agents.
