In this study, we examined the effects of combining C-CAM1-based therapy and TNP-470, a potent angiogenesis inhibitor, on prostate cancer in a xenografted tumor model. The direct cytotoxic effects of Ad-C-CAM1 (recombinant adenovirus containing C-CAM1 cDNA) and TNP-470 on DU145 cells in vitro were determined by microculture tetrazolium assay. The in vivo antitumor effects of either agent alone were studied in a DU145 xenografted tumor model. Cells were infected with Ad-C-CAM1 or the control virus at multiplicities of infection (m.o.i.) of 5 or 10 and then inoculated onto nude mice 48 h later. TNP-470 (0,17 or 35 mg/kg) was given 15,17 and 19 days after inoculation. Combined treatments in vivo were carried out to determine whether there were synergistic antitumor effects. Both Ad-C-CAM1 and the control virus were minimally toxic to DU145 in vitro. There was evident dose-dependent suppression of xenografted tumor growth by either Ad-C-CAM1 or TNP-470. By the median-effect analysis, combination of the two agents generated strong synergistic antitumor effects as shown by marked tumor suppression as compared to either treatment alone. The novel strategy may have clinical implications for the treatment of prostate cancer. ? 2002 Lippincott Williams & Wilkins. |
