Outline of Final Research Achievements |
The quasispecies state of HBV, HCV genome was analyzed by new sequencing technology. In HCV, the drug resistance mutation against DAA is minor clone so called drug resistant associated variants: RAV becomes dominant after treatment. In HBV, quasispecies state in which deletion mutant of HBV-PreS2 region and Pre S1 / S2 initiation codon mutation are existed. It is formed by persistent infection with or without antiviral treatment and existent ratio 1% or more is associated with the disease state. Further In HCC cases, an increase in the existent ratio of mutated clone in PreS2 region is closely related to liver carcinogenesis.
