title: Suppression of heat-induced p53 accumulation and activation by CDDP or x-rays in human glioblastoma cells.
abstract: We showed that the prominent suppressions of heat-induced accumulation and activation of p53 by CDDP or X-rays were observed in A-172 cells, but not in T98G cells. In addition, the interactive hyperthermic enhancement of CDDP or X-ray cytotoxicity was observed in A-172 cells, but not in T98G cells. Our findings indicate that suppressions of heat-induced accumulation and activation of p53 by CDDP or X-rays contribute positively to an interactive hyperthermic enhancement of CDDP- or X-ray cytotoxicity.
