摘    要:目的定量研究蛋白酪氨酸磷酸酶(PTEN)mRNA在口腔鳞状细胞癌及对应癌旁正常组织中的表达。了解PTEN基因的表达与口腔癌发生、发展的关系。材料和方法应用实时荧光定量PCR方法检测42例口腔鳞状细胞癌及对应癌旁正常组织中PTENmRNA的表达,Rotor-Gene Real-TimePCRAnalysisSoftware6.0软件进行mRNA定量分析,在SPSS14.0统计软件平台上用配对t检验方法统计检验。结果42例口腔鳞状细胞癌和对应癌旁正常组织中均有PTENmRNA表达。口腔鳞状细胞癌组织中PTENmRNA表达量[1.10±0.13(10gPTEN/logβ-actin)]低于相应癌旁正常组织(1.48±0.28),差异有统计学意义(P〈0.01)。结论口腔鳞状细胞癌的发生与PTENmRNA表达水平降低有一定关系。

Abstract:To investigate the expression of PTEN in oral squamous cell carcinoma (OSCC) and paired normal tissue and evaluate its correlation with OSCC. Methods The level of PTEN mRNA expression in 42 oral squamous cell carcinoma tissue and paired normal tissue were assayed using a quantitative real-time RT-PCR. Data was analyzed with SPSSld. 0 software package for paired t test. Results The expression of PTEN mRNA was detected in all OSCC and paired normal tissue. The level of PTEN mRNA in OSCC tissue [ 1.10 ± 0. 13 ( log PTEN/logβ - actin) ] was significantly lower than that of paired normal tissue ( 1.48 ± 0. 28) (P 〈 0. 01 ). Conclusion The decreased expression of PTEN mRNA contributes to the genesis of OSCC.
Keywords:PTEN oral squamous cell carcinoma real- time RT- PCR
