Chimeric constructs between two hepatitis B virus genomes confirm transcriptional impact of core promoter mutations and reveal multiple effects of core gene mutations.

abstract：:We previously demonstrated that cellular mRNAs are degraded in CD4 positive lymphocytes infected by the human immunodeficiency virus, HIV-1, but not in cells infected by the simian lentivirus, SIV. To begin to define the molecular mechanisms underlying this RNA degradation, we have established an in vitro RNA degradat...
