摘要 目的探讨乳腺癌细胞ret基因转录水平的表达及其与PI3KAktmTOR信号通路相关因子的关系。方法以乳腺癌细胞为研究对象,采用荧光定量聚合酶链式反应(RT-PCR)检测细胞中RET、PI3K、mTOR和AKT mRNA表达量,构建合成ret shRNA慢病毒载体,转染乳腺癌细胞,再次采用RT-PCR检测细胞中RET、PI3K、mTOR和AKT mRNA表达量。比较转染前后细胞中RET、PI3K、mTOR和AKT mRNA表达量,并采用Pearson线性相关分析法分析其细胞中RET mRNA表达量与其PI3K、mTOR和AKT mRNA表达量的关系。结果转染前细胞中RET、PI3K、mTOR和AKT mRNA表达量分别为0.851±0.126、0.872±0.126、0.845±0.087和0.769±0.355,均分别高于转染后的0.108±0.023、0.113±0.022、0.098±0.022和0.072±0.013(P<0.05)。Pearson线性相关分析结果显示,细胞中RET mRNA表达量与其PI3K、mTOR和AKT mRNA表达量均呈正相关(r=0.877、0.852、0.863,P<0.05)。结论乳腺癌细胞ret基因转录水平较高且与PI3KAktmTOR信号通路相关因子密切相关,可能通过调控PI3KAktmTOR信号通路而影响乳腺癌的发生发展,可能作为乳腺癌治疗的靶基因之一。
