Complementation of Wild-Type and Drug-Resistant Hepatitis B Virus Genomes to Maintain Viral Replication and Rescue Virion Production under Nucleos(t)ide Analogs.

ABSTRACT: As the open reading frames of hepatitis B virus (HBV) genomes are overlapping, resistance mutations (MTs) in HBV polymerase may result in stop codon MTs in hepatitis B surface proteins, which are usually detected as a mixed population with wild-type (WT) HBV. The question was raised how the coexistence of nucleos(t)ide analogs (NAs) resistance MTs and WT sequences affects HBV replication. In the present study, HBV genomes with frequently detected reverse transcriptase (RT)/surface truncation MTs, rtA181T/sW172*, rtV191I/sW182* and rtM204I/sW196*, were phenotypically characterized alone or together with their WT counterparts in different ratios by transient transfection in the absence or presence of NAs. In the absence of NAs, RT/surface truncation MTs impaired the expression and secretion
