Successfully established a dual aptamer modified tumor targeting gene and DOX delivery system mediated by recombinant adenovirus.
The uptake of ADDP-Ad5 and expression of reporter gene are enhanced by the system in LNCaP and PC3 cells.
ADDP-Ad5 significantly inhibits the cell growth of LNCaP and PC3 cells but not WPMY-1 cells.
ADDP-Ad5 is active in vivo against LNCaP and PC3 tumor xenografts and has no or slight toxicity to the mice.
