摘要
目的 研究脆性组氨酸三联体基因(fragile histidine triad gene,FHIT)在甲状腺乳头状癌(papillary thyroid carcinoma,PTC)及其配对癌旁组织(non-carcerous epithelium,NCE)中的表达及其临床意义.方法 采用逆转录聚合酶链反应(RT-PCR)检测60例PTC及相对应NCE中FHIT基因的表达情况.结果 PTC中FHIT基因表达阳性率为45.0% (27/60),明显低于NCE 100.0% (60/60),其差异有显著性(P<0.01);PTC中FHIT基因mRNA表达水平与患者的病理学分级、TNM分期、淋巴结转移有相关性,差异有统计学意义(P<0.05).结论 FHIT基因转录表达异常可能为一重要的分子改变参与了PTC的发展及演变,可望成为PTC病情监测及预后判断的一个生物学指标.
Objective To study fragile histidine triad gene(FHIT) gene mRNA expression in 60 samples of papillary thyroid carcinoma(PTC) and matched adjacent non-concerous tissues (NCE),and to explore the role of FHIT gene in the development in PTC.Methods Reverse transcription polymerase chain reaction(RT-PCR) was used to detect FHIT gene mRNA expression in 60 samples of PTC and matched NCE.Results In PTC tissues,the positive rate of FHIT gene mRNA expression was 45.0% (27/60),lower than that in NCE tissues (100.0%,60/60).FHIT gene mRNA expression was correlated with pathology stage,TNM stage and lymph node metastasis (P < 0.05).Conclusion FHIT loss and transcript abnormality might play important roles in proliferation and metastasis of PTC,and might be a useful marker for evaluating the biological behavior of PTC.
