Integration of genomes on infectious viruses

The article contains a review relating to the integration of genomes of infectious viruses in Eukaryotic cells. Data are presented that were obtained in the study of tissue cultures chronically infected with viruses, in the study of pathologic and ecologic processes. Based on the evidence accumulated, some theoretical and applied aspects of the problem are discussed.

Integration of viral genomes

DNA transcripts of infectious RNA viruses were found to be integrated in the DNA of chronically-infected tissue cultures. DNA sequences homologous to RNA of measles virus were found in tissues affected with systemic lupus erythemotosus. These data open up a new class of virus-cell interaction that may be a result of cooperation between infectious and oncogenic viruses.
