Abstract/OtherAbstract:
Infection of a human T-cell leukaemia cell line (HSB-2) with HHV-6 led to the induction of exosome-like-particles attached to newly formed HHV-6 enveloped particles and to amplification of a 1642 bp molecule consisting of a partial human endogenous retrovirus (HERV)-E polymerase gene and repetitive sequences. We initiated an analysis of transcriptional patterns of predicted genes from HERV-E sequences in normal and malignant haematopoietic cells. Transcription patterns of regions corresponding to gag, pol and env genes at different chromosomal loci varied among cell types tested. Several specific transcripts were only observed in malignant haematopoietic cells and transcriptional activity varied among different malignant cell types. A transcript of 7.1 kb spanning the complete gag, pol and env gene region, originating from chromosome 8p23, was identified in normal peripheral blood cells and cells of the chronic myeloid leukaemia cell line K562. Our study describes new active HERV-E sequences and new loci throughout the human genome.
