SUBGROUP B RECOMBINANT HUMAN ADENOVIRUS VECTOR, AND METHODS FOR CONSTRUCTING AND FOR USING THE SAME |
摘要 |
A method for reconstructing a replication-selective oncolytic adenovirus using a subgroup B recombinant human adenovirus vector Ad11-5EP. The method includes: 1) deleting E1A CR2 gene and/or anti-apoptotic gene E1B 21K that is necessary for viability of an adenovirus in normal cells but not necessary in tumor cells; 2) inserting a tumor-specific promoter to drive the expression of E1A gene; 3) re-directing a cellular tropism of Ad11-5EP according to receptors on a tumor cell surface; or 4) allowing adenovirus to selectively replicate in tumor cells. |

1. A method for reconstructing a replication-selective oncolytic adenovirus using a subgroup B recombinant human adenovirus vector Ad11-5EP (SEQ ID NO: 1), the method comprising one of the following steps:
1) deleting E1A CR2 (SEQ ID NO: 8) gene and/or anti-apoptotic gene E1B 21K (SEQ ID NO: 9) that is necessary for viability of an adenovirus in normal cells but not necessary in tumor cells; 2) inserting a tumor-specific promoter to drive the expression of E1A gene; 3) re-directing a cellular tropism of Ad11-5EP (SEQ ID NO: 1) according to receptors on a tumor cell surface; or 4) allowing adenovirus to selectively replicate in tumor cells. |
