Abstract

Head and neck tumors are one of the major public health problem all over the world. Cellular response of larynx carcinoma to cisplatin (CDDP) chemotherapy occurs both in cell-interdependent and cell-autonomous pathways. In the first pathway, cytotoxic signal transduction is mediated via gap-junctional intercellular communication (GIJC). CDDP also influence tumor cell migration.The aim of this study was the analysis of the effect of CDDP (0.5 microg/ml and 1.5 microg/ml) on the gap-junction intercellular communication and motility, respectively, in two new cell cultures (RK33 and RK45) derived from human larynx carcinoma. The migration of RK45 cell line was slightly inhibited and RK33 not affected after the incubation with CDDP. Tumor cells incubation with CDDP resulted in farther LY migration through neighboring cells beyond monolayer wound than in control cultures.In conclusion, there is a relationship between intercellular communication via gap junctions and motility of laryngeal tumor cells after CDDP application.
