摘 要: | 目的:研究p53基因点突变与乳腺癌发生发展关系。该当:应用多聚酶链反应-限制性片段长度多态性(PCR-RFLP)检测75例人乳腺癌标本p53基因第7外显子内248,249位密码子的点突变,结果:75例乳腺癌标本p53基因第7外显子全长序列CR扩增产物经限制性内切酶MspI酶切后,发现2例为突变型,用HaeⅡ酶切后未发现有突变,结论:上述结果揭示p53基因第7外显子内248位密码子的突变为乳腺癌p5

Abstract: | Purpose To study the relationship between point mutation in p53 exon 7 and human breast carcinoma. Methods Using PCR RFLP, we detected point mutations in p53 exon 7 in 75 cases of the breast carcinomas. Results 2 cases had point mutations in code 248 of p53 gene. Conclusions It is indicated that the point mutation was one of the mutational hot spot in p53 gene. |
