Abstract Background Hepatitis C virus HCV is one of the main causes of liver-related morbidity and mortality. Although combined interferon-a-ribavirin therapy is effective for about 50 of the patients with HCV better therapies are needed and preventative vaccines have yet to be developed. Short-hairpin RNAs shRNAs inhibit gene expression by RNA interference. The application of transient shRNA expression is limited however due to the inability of the shRNA to replicate in mammalian cells and its inefficient transduction. The duration of transgene shRNA expression in mammalian cells can be significantly extended using baculovirus-based shRNA-expressing vectors that contain the latent viral protein Epstein-Barr nuclear antigen I
