<p>Expression vectors that include a pre-selected therapeutic nucleic acid operably linked to a tumor specific or cell type-speci fic promoter and a Tcf-4β-catenin enhancer are provided. The therapeutic nucleic acid preferably includes a gene encoding a therapeutic protein for treatment of, for example, cancer. Methods for targeted expression of therapeutic nucleic acid, and methods for treating cancer, utilizing the expression vectors described herein, are also provided. Host cells are also provided that have been transformed with the expression vectors described herein.</p> |
