摘要

We analyzed by blot hybridization the state and structure of the viral DNA in an exceptional BK virus-induced hamster tumor (choroid plexus papilloma Vn-324) that contains about one copy of the BK virus genome per cell, but no intranuclear T antigen as assayed by indirect immunofluorescence. The BK viral DNA was found to be integrated into cellular DNA at a site in the middle of the early region of the viral genome (between 0.32 and 0.41 map units). The structure of the inserted viral DNA shows that it cannot encode a full-size large T antigen, but may encode small T antigen and an N-terminal portion of large T antigen.
