Research Abstract |
Adenovirus vector is one of the most widely used vectors for cancer gene therapies. One of the serious problems associated with adenovirus vector-based gene therapy is that expression of Coxsackievirus and Adenovirus Receptor (CAR), a receptor for the adenovirus vector, is often reduced among advanced cancers. In this study, we attempted to highly enhance expression of a cargo gene by modifying promoter and applying a developed adenovirus-adaptor protein. A newly designed Ad-REIC showed 10 to 100 fold higher expression in a cancer specific manner than that attained by previous one. This vector certainly improved the therapeutic effect for a wide variety of human cancers. The selective anti-cancer function of the new Ad-REIC shows a great promise for clinical application.
