Abstract
Objective: To explore the anti-tumor effects of Egr-IFNgamma gene therapy combined with {sup 125}I-UdR radionuclide therapy in mice bearing H22 hepatocarcinoma and its mechanism. Methods: The recombinant plasmid pcDNAEgr-IFNgamma mixed with liposome was injected into tumor. 48 h later, 370 kBq {sup 125}I-UdR was injected into tumor. The tumor growth rates at different times were observed. After 3 d gene-radionuclide therapy, the concentration of IFNgamma in cytoplasm of H22 cells and cytotoxic activities of splenic CTL of the mice in different groups were examined. Results: The tumor growth rates of pcDNAEgr-IFNgamma + {sup 125}I-UdR group were obviously lower than those of control group, {sup 125}I-UdR group and pcDNAEgr-1 + {sup 125}I-UdR group 6-15 d after gene-radionuclide therapy. IFNgamma protein was found in cytoplasm of H22 cells in pcDNAEgr-IFNgamma + {sup 125}I-UdR group after 3 d gene-radionuclide therapy. Cytotoxic activity of splenic CTL in pcDNAEgr-IFNgamma + {sup 125}I-UdR group was significantly higher than that in the other groups (P<0.01). Conclusions: The anti-tumor effects in vivo of pcDNAEgr-IFNgamma gene therapy combined with {sup 125}I-UdR radionuclide therapy are better than those of {sup 125}I-UdR therapy. (authors)
