Currently available therapeutics for hepatitis B virus (HBV) infection have limited effectiveness in patients and often do not clear HBV from the liver due to the persistence of the stable, double-stranded (ds) DNA genome of HBV. By designing zinc finger proteins (ZFPs) to bind the dsDNA genome of a model virus, duck HBV (DHBV), we were able to inhibit viral transcription, and subsequently, viral protein and progeny production. This inhibition is likely due to competition for DNA binding sites between the ZFPs and transcription factors, and interference with read-through transcription by RNA polymerase across the ZFP-binding region. Taking into account some design considerations, this method of inhibiting viral transcription can be applied to other viral infections where viral dsDNA occurs. © 2010 Springer Science+Business Media, LLC.
