Abstract
Purpose: Human herpesviruses have been associated with the etiology of several human cancers. The role of these viruses in carcinogenesis has not yet been clarified. This study focused on identifying and characterizing the transforming potential of cloned DNA fragments from human cytomegalovirus(HCMV).
Materials and Methods: Multiple DNA fragments of HCMV were applied to cells for transformation. Morphological transforming region II(mtrII) of HCMV strain Towne has been identified to a 3.0kb Xbal-BamHI DNA fragment which was retained in transformed cells. The transforming activity was induced by a 980 bp Ball-Xho I subfragment(pBS980) containing both promoter/ regulatOTy elements as well as three open reading frames(ORFs), i.e., 790RF’ 830RF, and 340RF. The ORFs have been evaluated for transforming potential in NIH3T3 cells. Results: MtrII(pBS980) has Bglll restriction enzyme site which divides into two subfragments, pBS440 and pBS540, the latter has whole 830RF, 340RF, and fragment of 790RF, the former has only fragment of 790RF. Among three ORFs, 830RF and 340RF were not functional in transformation, because in pBS540 these ORFs were not truncated.
Conclusion: The 790RF(79-aa transforming peptide) has allowed a better approach to determine the role of HCMV in human carcinogenesis.
