| Research Abstract |
Cisplatin is a chemotherapeutic agent having a potent anti-tumor effect. However, in some cases, cisplatin has often withdrawn due to renal toxicity. Therefore, we tried to elucidate mechanisms involved in renal toxicity of cisplatin, and find out therapy to improve it, and thus, it might be able to reduce the nephrotoxicity without disturbing the anticancer effect of cisplatin by combination with drugs to elucidate mechanisms involved in renal toxicity of cisplatin. In the present research, we have proposed a novel mechanism(s) on the development of cisplatin-induced renal failure that cisplatin accelerates chymase-dependent production of IL-18 which stimulates aldosterone synthesis, and that extended excretion of cisplatin causes renal inflammation. Thus, concomitant use of inhibitor(s) of chymase activity or aldosteron binding to its receptor with cisplatin could be reducing the pathogenesis of renal damage by cisplatin therapy.
