Hoshimaru, Minoru; Shiga-ken, Japan | | Summary: | Described herein is a retroviral vector containing a regulatable transactivator element and a heterologous gene, and methods of its use in the genetic modification of cells. The invention relates to a novel regulatable retroviral vector in which the v-myc oncogene is driven by a tetracycline-controlled transactivator and a human cytomegalovirus minimal promoter fused to tet operator sequences. Further disclosed are methods by which such a vector may be used for the immortalization of adult neuronal progenitor cells and for the regulation of heterologous Producer cell lines which produce high titers of the recombinant retrovirus. Therapeutic and experimental applications are provided for the use of this oncogene in rendering neuronal precursor cells immortal until the transactivator is switched off. | | Abstract: | | | US Patent Website: | Click Here for Full Text of Patent | | Title Number: | US5770414 | | Application Number: | US1996000602203 | | Date Filed: | 20/02/1996 | | Date Published: | 23/06/1998 | | Assignee: | The Regents of the University of California, Oakland, CA, USA |
