title: Activation of a cellular onc gene by promoter insertion in ALV-induced lymphoid leukosis.
abstract: Analyses of DNA and RNA from avian leukosis virus (ALV)-induced lymphomas have provided strong evidence that, in most tumours, ALV induces neoplastic disease by activating the c-myc gene, the cellular counterpart of the transforming gene of MC29 virus. The data indicate that, as a rare event, the ALV provirus integrates adjacent to the c-myc gene and that transcription, initiating from a viral promoter, causes enhanced expression of c-myc, leading to neoplastic transformation.
