摘要 目的 探讨影响乳腺癌组织中PDK4的表达与预后的相关性。方法 PubMed数据库The Gene Expression Omnibus（GEO, http://www.ncbi.nlm.nih.gov/geo/）分析PDK4在正常乳腺及乳腺癌组织中的表达水平。使用The Kaplan–Meier plotter（www.kmplot.com）分析工具评估PDK4表达水平与乳腺癌临床预后的相关性。TGF-β细胞因子处理MCF-7细胞系，Real-time PCR技术检测经处理后MCF-7细胞系中PDK4 mRNA表达水平。siRNA干扰技术降低细胞内PDK4的表达水平，Transwell检测MCF-7细胞的侵袭能力。结果 PDK4在乳腺癌组织中的表达水平低于正常乳腺组织，并且PDK4低表达与乳腺癌预后差呈正相关；在乳腺癌细胞系中，TGF-β降低PDK4 mRNA表达水平，且PDK4的低表达增强了MCF-7细胞的侵袭能力。结论 PDK4低表达是乳腺癌预后差的一个重要指标
