Analysis of HBV RNA levels across genotypes. HuH-7 cells were transfected with linear full-length HBV genomes of genotypes A2, B2, C1, D1, and F1b. Three days post-transfection, cells were harvested, total RNA was extracted, and pgRNA (A) and Precore mRNA (B) levels were analyzed by transcript-specific RT-qPCR. (C) cccDNA replicative activity was determined as molecules of pgRNA synthesized per cccDNA (pgRNA/cccDNA). (D) The number of Precore mRNA transcripts produced per cccDNA (Precore RNA/HBVccc) was used to assess HBV transcriptional efficiency. Values shown represent the mean±standard deviation of three independent experiments. *: difference in relation to gtA2, ξ: difference in relation to gtB2, #: difference in relation to gtC1 and &: difference in relation to gtD1. Two symbols: p<0.0001.
