| Outline of Final Research Achievements |
The effectiveness of a new strategy against human renal cell carcinomas (RCCs) that modifies interleukin (IL)-6 signaling was investigated in vitro and in vivo. In RCC cell lines, interferon (IFN)-α alters the autocrine production of the proinflammatory cytokine IL-6. The growth inhibitory effects of IFN-α under IL-6R knockdown conditions by tocilizumab were demonstrated by MTT assay. The in vivo effects of injections of tocilizumab and IFN administration were evaluated in groups of nude mice bearing s.c. xenografts of 786-0. The growth of the tumors in mice receiving combination therapy with tocilizumab and IFN-α was significantly suppressed in comparison with those in the tocilizumab, IFN-α and non-treated groups.TRAIL was up-regurated in the tumors which were treated with combination therapy with tocilizumab and IFN.
