目的 研究G蛋白信号通路调节蛋白5基因(rgs5)在非小细胞肺癌中的转录水平及其与病人临床病理参数之间的关系.方法 收集2007年9月~2008年9月49例肺部占位手术切除标本,RT-PCR分析比较病灶组织及病灶旁组织rgs5的mRNA水平,并用X2检验及单因素相关分析分析病人临床病理参数与rgs5转录水平的关系.结果 所有病例中,共有45%的病例(22/49)病灶组织中的rgs5 mRNA水平高于病灶旁组织,其中良性组织和恶性组织高表达率分别为38%(5/13)和47%(17/36).良性与恶性组织中rgs5 mRNA的转录水平没有统计学差异(P=0.436).相关分析提示,肺癌组织中rgs5转录水平与肿瘤的淋巴结转移存在负相关关系(Spearman相关系数=-0.433,P=0.008),而与其他临床病例参数相关关系不明确.结论 rgs5高转录水平与肿瘤的淋巴结转移呈负相关,提示rgs5在调节肿瘤转移方面有一定的作用.
