1少突胶质细胞瘤中PTEN基因突变和10q染色体的杂合性缺失分析显示文摘目的 探讨PTEN基因突变和 10q染色体的杂合性缺失 (LOH)在少突胶质细胞瘤发生和发展中的意义。 方法 以 5 5例少突胶质细胞瘤和混合性胶质细胞瘤为研究对象 ,PCR扩增PTEN基因所有 9个外显子 ,其产物经变性梯度凝胶电泳 (DGGE)后 ,DNA序列分析检测PTEN基因突变。应用不同颜色荧光标记 10q微卫星标志物引物 ,PCR扩增后 ,其产物在自动测序仪上进行聚丙烯酰胺凝胶电泳 ,用GeneScan软件分析LOH。 结果 2 5 5例有PTEN基因突变 ,1例是PTEN的第 9外显子的 2 0号T碱基缺失导致终止密码 35 1易位至 347,另 1例在 139位发生C到A的转换 ,使得Phe变成Leu。 2 3 5 5 (4 2 % )例出现染色体 10q的LOH ,其中 15 / 5 5例位于 10q2 3,3(D10S5 4 1) ,其为PTEN基因位点 ,12 / 5 5例 10q微卫星标志物位点完全缺失。 结论 在少突胶质细胞瘤中PTEN突变较少见 ,而 10qLOH较频繁 ,尤其在恶性度高的少突胶质细胞瘤中表现明显 ,提示 10qLOH与少突胶质细胞瘤恶性进展有关 ,且何杰 汪万英 徐杰 Hoang-Xuan Khe Sanson Marc 2003解剖学报2003,34,3:3
