  • Title: Stable inhibition of hepatitis B virus expression and replication in HepG2.2.15 cells by RNA interference based on retrovirus delivery.
    Author: Jia F, Zhang YZ, Liu CM.
    Journal: J Biotechnol; 2007 Jan 30; 128(1):32-40. PubMed ID: 17049658.
    Abstract:
    RNA interference (RNAi) of virus-specific genes has emerged as a potential antiviral strategy. In order to suppress hepatitis B virus (HBV) expression and replication, a retrovirus-based RNAi system was developed, which utilized the U6-RNA polymerase III (Pol III) promoter to drive efficient expression and deliver the HBV-specific short hairpin RNAs (shRNAs) in HepG2.2.15 (2215) cells. In this system, the retrovirus vector with a puromycin selection marker was integrated into the host cell genome and allowed stable expression of shRNAs. In Puro-resistant 2215 cells, the levels of both HBV protein and mRNA were dramatically reduced by over 88% and HBV replication was suppressed. The results demonstrated that retrovirus-based RNAi technology will have foreseeable applications both in experimental biology and molecular medicine.
