摘要
Abstract
By southern hybridization with 1. 8 kb cDNA probe
a high frequency (40. 5 % ) of structural abnor- mality of p
53
gene was observed in primary nasopharyngeal carcinoma (NPC) biopsies. The regions of ex- ons 1 to 4 of the gene were examined by polymerase chain reaction-single strand con formation polymor- phism
no point mutation was found. Because very low rate of point mutation had been reported in exons 5 to 8
we considered that structural abnormality in the region of e-cons 1 to 8 of the gene might be uncom- mon in NPC. The spectrophotometer scanning analysis of autoradiograms and rehybridization investigation of nitrocellulose filter with exon 11 probe indicated that most of structure aberrations we observed might be rearrangement occurring in exon 11.
