title: Transduction of LacZ gene into leukemia cells using viral vectors of retrovirus and adenovirus.
abstract: Recent developments in gene therapy techniques enable us to introduce new genetic information into hematopoietic cells. Among the various techniques, we focused on two viral vector systems, one using a retrovirus and the other an adenovirus. By using an adenoviral vector we could transduce and highly express bacterial beta-galactosidase (LacZ) gene under the control of the CAG (cytomegalovirus enhancer with chicken beta-actin promoter) promoter in various hematopoietic cells, although the expression persisted for only two weeks. The retroviral vector (MFG) could transduce the LacZ gene into hematopoietic cells almost as well as the adenoviral vector using the repetitive infection protocol. The retroviral system could maintain the expression of transduced cells quite longer than the adenoviral system. Differential use of these two vector systems may be helpful for the gene transduction into various kinds of hematopoietic cells (Lin et al., manuscript in preparation).
