...AAV2 suppresses cancer is linked to its ability to slow cell-cycle progression by decreasing cancer cell proliferation rates and causing growth arrest. In this study, the team first used HPV infected epithelial cells and normal human epithelial cells, which are natural hosts for both AAV2 and HPV.
