摘要: 目的 研究肿瘤坏死因子相关凋亡诱导配体(TRAIL)及其受体TRAIL-R2和TRAIL-R4在非小细胞肺癌(NSCLC)中的表达及其意义。方法 采用酶联免疫吸附试验(ELISA)检测79例NSCLC患者与80例正常人血清中TRAIL的表达水平,采用免疫组织化学法检测42例NSCLC组织及配对癌旁正常组织中TRAIL-R2和TRAIL-R4的表达水平。分析TRAIL、TRAIL-R2、TRAIL-R4与NSCLC患者临床病理特征的关系。结果 TRAIL在NSCLC患者血清中的表达明显低于正常人[(994.3±293.0)ng/ml∶(1 141.7±266.1)ng/ml],差异具有统计学意义(t=3.29,P=0.00)。TRAIL的表达与NSCLC患者的临床分期(F=2.28,P=0.00)、分化程度(t=5.76,P=0.00)相关。TRAIL-R2在NSCLC组织中的阳性表达率为73.8%(31/42),明显低于正常组织中的阳性表达率100.0%(42/42)(χ2=3.88,P=0.05),TRAIL-R2的表达与NSCLC患者的临床分期(χ2=27.89,P=0.00)、分化程度(χ2=9.50,P=0.00)相关。TRAIL-R4在NSCLC组织中的阳性表达率为81.0%(34/42) ,明显高于正常组织中的阳性表达率50.0%(21/42) (χ2=7.34,P=0.01),TRAIL-R4的表达与NSCLC患者的临床分期(χ2=17.82,P=0.00)、分化程度(χ2=4.47,P=0.03)相关。在NSCLC组织中,TRAIL-R4与TRAIL-R2的表达呈负相关(r=-0.67,P=0.01)。结论 在NSCLC中,TRAIL、TRAIL-R2表达减少,TRAIL-R4表达增多,三者可能促进了NSCLC的发生发展,可为NSCLC临床治疗提供靶点。

Abstract: Objective To investigation the expressions of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and its receptors in non-small cell lung cancer (NSCLC) and their clinical significances. Methods The serum expression levels of TRAIL in 79 cases of NSCLC and 80 cases of normal subjects were detected by enzyme-linked immunosorbent assay (ELISA). The expressions of TRAIL-R2 and TRAIL-R4 in 42 cases of NSCLC and matched normal tissues were detected by immunohistochemistry. The relationships among TRAIL, TRAIL-R2, TRAIL-R4 and clinicopathologic features of NSCLC were analyzed. Results The expression of TRAIL in NSCLC patients was lower than that in normal human [(994.3±293.0)ng/ml vs. (1 141.7±266.1)ng/ml, t=3.29, P=0.00]. The expression of TRAIL was closely correlated with clinical stage (F=2.28, P=0.00) and differentiated degree(t=5.76, P=0.00). The positive expression rate of TRAIL-R2 in NSCLC was 73.8% (31/42), significantly lower than that in the normal tissue 100.0% (42/42) (χ2=3.88, P=0.05). The expression of TRAIL-R2 was closely correlated with clinical stage (χ2=27.89, P=0.00) and differentiated degree (χ2=9.50, P=0.00). The positive expression rate of TRAIL-R4 in NSCLC was 81.0% (34/42), significantly higher than that in the normal tissue 50.0% (21/42) (χ2=7.34, P=0.01). The expression of TRAIL-R4 was also closely correlated with clinical stage (χ2=17.82, P=0.00) and differentiated degree (χ2=4.47, P=0.03). There was a negative correlation between the expression of TRAIL-R2 and TRAIL-R4 in NSCLC (r=-0.67, P=0.01). Conclusion The decrease of TRAIL and TRAIL-R2 and increase of TRAIL-R4 expression may promote the occurrence and development of NSCLC, and they may provide targets for clinical treatment of NSCLC.
