Key result
RNA aptamer 3-07 strongly inhibited HCV IRES-dependent translation, reducing luciferase activity to 10% of control levels in vitro and significantly decreasing activity in HeLa cells.
Absolute Event Rate: 10% vs 100%
Rationally designed RNA aptamers targeting domain IIId of the HCV IRES can inhibit viral translation, suggesting potential as anti-HCV drugs.

Supports aptamer-based HCV IRES inhibition; hypothesis-generating and requires in vivo validation before any clinical consideration.
Koji Kikuchi (2005) studied Hepatitis C virus (HCV) infection (in vitro/cell culture model). RNA aptamer 3-07 vs. Control (no aptamer or mutant aptamers) was evaluated on Inhibition of IRES-dependent translation (luciferase activity). RNA aptamer 3-07 strongly inhibited HCV IRES-dependent translation, reducing luciferase activity to 10% of control levels in vitro and significantly decreasing activity in HeLa cells.
