目的:观察DNA甲基化酶( DNMT1、DNMT3a和DNMT3b)与肺癌危险性的关系。方法:采用酶联免疫吸附法检测136例肺癌患者(肺癌组)、141例肺良性疾病患者(对照组)血清DNMT1、DNMT3a和DNMT3b的水平。分析性别、年龄、吸烟史、肺癌组织学类型和临床分期对血清DNMT1、DNMT3a和DNMT3b的影响,以及血清DN-MT1、DNMT3a和DNMT3b表达水平与肺癌危险性的关系。结果:肺癌组DNMT1、DNMT3a表达水平(μg/L)[12.64(9.67~17.07),0.74(0.61~1.05)]高于对照组[11.07(7.85~17.59),0.66(0.49~1.00)(Z =1.884, P=0.002;Z=1.788,P=0.003)],DNMT3b差异无统计学意义。按3种DNMTs水平的百分位数25%、50%、75%为分界点分别将肺癌组和对照组分为4层,结果显示随着DNMT1、DNMT3a表达水平增加,患肺癌的危险性增加(χ2趋势=4.062和7.853,P<0.05)。结论:肺癌患者血清中DNMT1、DNMT3a表达水平显著升高,检测血清DNMTs的变化可预测患肺癌的风险。

Aim: To explore the association of DNA methyltransferases ( DNMT1, DNMT3a and DNMT3b) and the risk of lung cancer .Methods:The levels of DNMT1, DNMT3a and DNMT3b in serum of 136 patients with lung cancer ( cancer group ) and 141 patients with benign pulmonary diseases ( control group ) were tested by ELISA .The impact of gen-der, age, smoking history, tumor histological type and stage on serum DNMT 1, DNMT3a and DNMT3b and associations between DNMT1, DNMT3a or DNMT3b and lung cancer risk were analyzed .Results:The levels of DNMT1 and DNMT3a (μg/L) in cancer group were[12.64(9.67-17.07), 0.74(0.61-1.05)], significantly higher than the control group [11.07(7.85-17.59), 0.66(0.49-1.00)(Z=1.884,P=0.002;Z=1.788,P=0.003)].The levels of DNMT3b had no significant difference between the 2 groups.When the subjects were categorized into four layers based on the 25%, 50%, 75%cut-off point of three DNA methyltransferases , it was shown that overexpressing of DNMT 1 and DNMT3a had increased risk of lung cancer (χ2trend=4.062 and 7.853,P<0.05).Conclusion:DNMT1 and DNMT3a are overexpressed in serum of lung cancer patients and detection the DNMTs levels could predict the risk of lung cancer .
