| Research Abstract |
The integration sites of bovine leukemia virus(BLV)in leukemiccells were analyzed using 90 tumor tissues from 48 0f leukemic cattle. Although the integration sites were not located in a particular chromosome, the BLV provirus wasintegrated into transcription units at a frequency of 43.6% and the transcriptional direction of the proviruswas in accordance with that of the integrated host genes in 62.5%.The integration sites were located in introns of the host gene, excluding only one site.BLV provir1.ts did not favor integration near transcription start sites and CpG islands.It is suggested that the integration site of the BLV provirus in leukemi ceells is relatedto the suppression of viral gene expression.
