Research Abstract

We have investigated the anti-tumor effect of connexin (Cx) gene, component of intercellular gap junction. Finally 5-aza-2'-deoxyxytidine could induce Cx32 expression in renal cell carcinoma, which exerted not only anti-proliferative effect but also improvement of chemotherapeutic cytotoxicity. On the other hands, Cx43 was found to enhance cisplatin cytotoxicity against mesothelioma. Above all, Cx could be useful for treatment of refractory cancers.
