Abstract excerpt
The downstream (3') long terminal repeat (LTR) of an avian retroviral provirus is unable to act as an efficient promoter of transcription when a transcriptionally active upstream (5') LTR is present. This transcriptional interference may explain the observation that only deleted proviruses have been observed inserted adjacent to c-myc in avian leukosis virus induced lymphomas of chickens.
