Title:
RECOMBINANT ADENOVIRUS WITH INCREASED SAFETY AND ANTICANCER ACTIVITIES, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2014/081229
Kind Code:
A1
Abstract:
The present invention relates to a recombinant adenovirus with increased in-vivo safety, tissue specificity, and anticancer activities, and a use thereof. Specifically, the recombinant adenovirus comprising: a promoter of the liver tissue-specific phosphoenolpyruvate carboxykinase (PEPCK) gene; a trans-splicing ribozyme which is operably linked to the promoter and acts on a cancer-specific gene; a therapeutic gene or a reporter gene which is linked to the 3' exon of the ribozyme; and a serotype 35 fiber knob and a serotype 5 shaft, in which the orf4 gene is deleted from adenovirus E1, E3 and E4 orf1, shows remarkable in-vivo safety, high specificity for a target tissue, and remarkable anticancer effects, and thus can be useful for an anticancer drug or a cancer diagnostic agent as a gene delivery vector.
