Abstract:: |
Objective The aim of this study was to analyze mutation of p53 and k-ras genes in lung cancer related to residential radon exposure. Methods PCR amplification,PCR-SSCP electrophoresis,and sequence analysis were carried out. Results Five of 9 lung cancer cases were found to be positive with p53 PCR-SSCP electrophoresis techniques,and in 3 among the 5 base substitution was observed. Conclusion Five of the seven cases of lung cancer 200-350 Bq·m-3 ·a-1 radon level had p53 gene mutation,which might be related to age and smoking status of the patients. |
