目的:观察重组TRAIL腺病毒(Ad5-TRAIL及Ad5F35-TRAIL)对人非小细胞肺癌(nonsmall-cell lung cancer,NSCLC)原代培养细胞和细胞株的凋亡诱导作用,探讨两种Ad-TRAIL用于肺癌基因治疗的价值。方法:采用流式细胞术检测人肺癌细胞系A549、Z79... 目的:观察重组TRAIL腺病毒(Ad5-TRAIL及Ad5F35-TRAIL)对人非小细胞肺癌(nonsmall-cell lung cancer,NSCLC)原代培养细胞和细胞株的凋亡诱导作用,探讨两种Ad-TRAIL用于肺癌基因治疗的价值。方法:采用流式细胞术检测人肺癌细胞系A549、Z793、QG56和NCI-H520及10例原代培养肺癌细胞中CAR和CD46的表达水平;分别以Ad5-TRAIL及Ad5F35-TRAIL重组腺病毒按MOI 10和50感染上述细胞,48 h后Annexin V-FITC双标法流式细胞术检测细胞的早期凋亡。结果:A549、Z793、QG56和NCI-H520 4株肺癌细胞中,CD46的表达均明显高于CAR表达。Z793、QG56细胞对Ad5-TRAIL和Ad5F35-TRAIL的作用较敏感,MOI=10感染后凋亡率分别为(11.76±2.10)%、(15.96±2.89)%和(6.05±1.58)%、(10.11±1.26)%,显著高于对照组[(2.33±0.37)%和(5.95±1.89)%,P<0.05];MOI=50感染时NCI-H520细胞凋亡率分别为(12.89±3.2)%和(9.08±1.35)%,与对照组(7.04±2.17)%相比差异无统计学意义(P>0.05);Ad5-TRAIL和Ad5F35-TRAIL均不能诱导A549细胞凋亡。10例原代肺癌细胞CD46表达也明显较CAR高;Ad5-TRAIL或Ad5F35-TRAIL感染后,5例的原代肺癌细胞检测到凋亡;与Ad5-TRAIL相比,Ad5F35-TRAIL诱导的凋亡率更高。结论:两种TRAIL重组腺病毒对非小细胞肺癌细胞均有凋亡诱导作用,Ad5F35-TRAIL的作用强于Ad5-TRAIL,更适合于非小细胞肺癌的基因治疗。 展开更多

Objective: We explored the expression of coxsackie and adenovirus receptor (CAR) in small cell lung cancer (SCLC) tissue. Methods: CAR expression in 31 SCLC was assessed in formaldehyde-fixed, paraffin-embedded tissue according to the EnVision immunohistochemistry procedure, while 3 samples of surgical specimens of non-malignant lung disease were taken as the negative control. Results: We observed that the expression of CAR was detectable positive in all the 31 cases from the small cell lung cancer tissue, in contrasting that non-malignant lung tissue control. Conclusion: The high expression of CAR appeared in SCLC tissue indicates that it play an important role in of adenovirus vector-based gene therapy in SCLC. 展开更多
