摘要: 目的 探讨PAK1(p21 activated kinase 1)基因在喉癌组织中mRNA水平表达情况及临床意义。方法 采用实时定量多聚酶链式反应(qRT-PCR)检测喉癌组织和癌旁正常黏膜组织中PAK1基因的mRNA表达情况。结果 62例喉癌中PAK1基因mRNA水平的阳性表达率为72.58%(45例),PAK1的表达与肿瘤分级、淋巴结转移、临床分期和不良预后相关(P<0.05)。结论 喉癌中PAK1基因在mRNA水平表达的上调与喉癌的发生发展密切相关,并且与病理分级、淋巴结转移、临床分期、不良预后有关,表明PAK1可能成为喉癌治疗中的新靶点。

Abstract: Objective To explore the expression level and clinical significance of PAK1 mRNA in laryngeal squamous cell carcinoma.Methods The mRNA expression level of PAK1 was detected in laryngeal cancer samples and matched para-cancerous normal tissues by real-time quantitative RT-PCR(qTR-PCR).Results The positive rate of PAK1 mRNA expression was 72.58% in laryngeal cancer.The high level of PAK1 mRNA was correlated with poor differentiation,lymph node metastasis,advanced clinical stage and poor prognosis(P<0.05).Conclusion Our study demonstrated that up-regulation of PAK1 mRNA may closely correlated with the carcinogenesis and development of laryngeal cancer.It indicates that PAK1 may serve as a new therapeutic target for laryngeal cancer.
