Низкомолекулярные ингибиторы путей репарации двухцепочечных разрывов ДНК усиливают противовирусное действие системы CRISPR/Cas9 на моделях вируса гепатита B

The CRISPR/Cas9 nuclease system can effectively suppress the replication of the hepatitis B virus (HBV), while covalently closed circular DNA (cccDNA), a highly resistant form of the virus, persists in the nuclei of infected cells. The most common outcome of DNA double-strand breaks (DSBs) in cccDNA caused by CRISPR/Cas9 is double-strand break repair by nonhomologous end-joining, which results in insertion/deletion mutations. Modulation of the...
