Inhibition of tumor growth in xenografted nude mice with adenovirus-mediated endostatin gene comparison with recombinant endostatin protein.

Abstract

Endostatin gene therapy mediated by a recombinant adenoviral vector had significantly inhibited the growth of hepatocellular carcinoma BEL-7402 xenografted tumors at a high dose of 1 x 10(9) pfu compared with other groups. The analysis of dynamic expression of endostatin in vivo indicated that Ad/hEndo had acquired a high-level, relatively long-term expression in vivo and bioactivity capability.
