Research Abstract

Hepatitis B virus (HBV) DNA can be integrated into the host genome and co-exist after its replication become decreased. In this study we revealed that HBV integration does not occur randomly, but is preferentially located in the certain region of the host genome. In those regions, there are many human genes related to cell proliferation, suggesting that HBV integration plays some role in modulating cell cycle. This mechanism can be related to viral persistence in the host cells and resulting liver carcinogenesis.
