Abstract：
:We investigated the signal transduction pathway to low-dose radiation-induced apoptosis in vitro in the human peripheral primitive neuroectodermal tumor (pPNET) cell line with wild-type p53 established in our laboratory. Apoptosis was induced by 2Gy irradiation in an almost p53-dependent manner in this model except for a deficiency of the cleavage of caspase-9. It was detected 3 hours after irradiation by fragmentation assay. The expressions of p53, p21WAF-1 and Bax increased, in contrast to the gradually decreasing expression of Bcl-2, as observed by immunoblotting. Following this, cleavages of caspase-3 and PARP reached peak levels. There were no detectable increases in ERK expression and caspase-9 cleavage. In respect of the probability of other pathways to apoptosis, this cell line will provide a useful model both for investigating low-dose radiation-induced signal transduction pathway and for analyzing the biological characteristics of pPNET.
