项目摘要
Gene mutation analysis(1) Mutations of p53 gene(exon5-8) were analyzed in cases with nasal Nk/T-cell l lymphoma(NKTCL)(19from China(Bejin)and 23 from Japan) with use of polymerase chaln reaction(PCR)-slngle strand conformation polyrnorphism followed by direct sequencing. P53 gene mutations were found in 20 cases(47.6%) with missense mutations in 60% of cases. Mutation frequency in Bejiing(63%) washigher than that in Japan(39%)(2) c-kit gene mutations were examined in 23 cases with nasal NKTCL(14 from Bejiing and a from Japan) by PCR-SSCP analysis. Mutation frequency in China(71.4%) much higher than than that in Japan(22%). Mutated c-kit genes transfected into 293T cell did not generate constitutive activation of c-kit, thus nota gain-of-function mutation(3) p53(exon4-8), c-kit(exon 11, 17), k-ras(exon1, 2), and β-catenin gene(exon3), mutations were examined in 20 cases with nasal NKTCL from northeast dlstrict of China, P53 mutations were found in 40% of cases with significantly lower involvement of exon4 than Japan Mutations of c-kit gene were found in only 5% of cases. Mutations of k-ras and β-catenin were found 5% and 30% of cases, respectively. These findings showed that mutation frequency and pattern of suppressor gene and oncogenes were various by direct, suggestion that presence of different environment factors for developrnent of nasal NK/T cell lymphoma.
基因突变分析(1)应用聚合酶链反应(PCR)-单链构象多态性分析和直接测序技术,对19例中国人和23例日本人鼻NK/T细胞淋巴瘤(NKTCL)p53基因第5 -8外显子进行突变分析。P53基因突变20例(47.6%),错义突变占60%。(2)应用PCR-SSCP方法检测了23例鼻NKTCL患者(14例来自北京,1例来自日本)的c-kit基因突变。中国的突变频率(71.4%)远高于日本(22%)。突变的c-kit基因转染293 T细胞后,c-kit基因不产生组成性激活,因此未发现功能获得性突变(3)p53(exon 4 -8),c-kit(外显子11,17),k-ras对东北地区20例鼻NKTCL患者进行了β-catenin基因(exon 1,2)和β-catenin基因(exon 3)突变检测,P53基因突变率为40%,第4外显子突变率明显低于日本,c-kit基因突变率仅为5%。K-ras和β-catenin突变分别占5%和30%。这些结果表明,鼻NK/T细胞淋巴瘤的发生与不同的环境因素有关,其抑癌基因和癌基因的突变频率和突变方式也不同。
