ABSTRACT
A replication-deficient adenovirus encoding human interferon alpha2b, driven by the human cytomegalovirus (CMV) promoter, was constructed and characterized. This construct was used to infect human cells derived from different types of cancer. The production of protein and its secretion into the culture medium were tested by Western blotting and immunoassay. Inhibition of cell proliferation and antiviral activity, two of the most important biological activities of interferon, were observed with this construct. PC-3 cells, derived from human prostatic cancer, or Hep3B cells, derived from human hepatocellular carcinoma, were injected subcutaneously to generate and establish in vivo tumors in athymic nude mice. Intratumoral injection with the recombinant adenovirus expressing interferon alpha2b resulted in complete regression of tumor growth. Our results demonstrate that interferon gene delivery using recombinant adenoviral vectors may be a useful approach to treat a variety of cancers.
