Core Tip
Core tip: Hepatitis B virus (HBV) reactivation is an emerging clinical challenge for HBV carriers receiving anti-cancer chemotherapy. However, the mechanism for the sharp increase in viral replication in the early stages of chemotherapy is still unclear. In this research, we found that vincristine, which is a cytotoxic drug, had a direct stimulatory effect on HBV replication without the involvement of immune factors and that vincristine induced cell cycle arrest; cell proliferation inhibition may be conducive to viral replication, and this may be a novel mechanism of HBV reactivation following cytotoxic chemotherapy.
