细胞荧光素酶报告基因试验受CpG岛甲基化状态影响

Objective To investigate the effects of methylation status of CpG islands of endogenous E-cadherin (CDH1) gene on the promoter activity of corresponding genes in reporter assays. Methods The methylation statuses of CpG island of CDHI in 8 different cell lines were detected by methylation-specific PCR. CDH1 protein was analyzed by Western blotting. Two sets of pGL3 reporter vectors with different genotypes/haplotypes of the CDH1 promoter were constructed [pGI3-A(-73)/-C(-73)pGL3-H1/-H4]and used to transfect these cell lines. The differences between these promoter reporter vectors were analyzed by t-test. Results (1) CDH1 CpG island was unmethylated in AGS, MCF7, MKN74, and PC-3 cell lines,expressed in MCF7, MKN74, and PC-3 ,but not in AGS. Expression of CDH1 was silenced by methylation in HeLa, BGC823, A549, and RKO cell lines. (2) In the four CDH1 -unmethylated MCFT, M KN74, PC-3, and AGS cell lines ,the promoter activities of pGI3-C(-73)(as 0. 78±0. 10,0. 17±0.01,0. 11±0. 01,1.19±0. 18)were significantly higher than those of pGL3-A(-73)(as 0. 30±0. 08,0. 07±0. 01,0. 07±0. 01,0. 39±0. 04) (t values are -6. 298, -12. 349, -8. 128, -7.388, and P<0. 01). However, in the four C DH1 -methylated HeLa, BGC823, A549, and RKO cell lines, the promoter activity of pGL3-C(-73)(as 0. 09±0. 02,0. 13±0. 02,0. 05±0. 01,0. 01±0. 00) was significantly lower than that of pGL3-A(-73)(as 0. 16±0. 01,0.25±0.01,0. 11±0.03,0.03±0.00) (t valued at 5.958,11. 189,3. 661,13. 866,and P<0.05). (3) In the unmethylated MKN74 and methylated RKO cell lines, the promoter activities of pGI3-H1/-H4 were obviously and contrarily different(as 1.57±0. 23/0. 94±0. 06 and 0. 38±0. 02/0. 50±0. 04 ,t values were 4. 577 and -4. 915 ,P values were 0. 010 and 0. 003). Conclusion The methylation status of CpG island of the target gene in the tested cell lines affects the promoter activity in Reporter Assay significantly. The most active one may be the most suppressive one.

青春尾巴上的秘密

一最近一段时间,张益益老师觉得很奇怪,因为,她经常会收到一些莫名其妙的礼物。那天放学之后,她随着大伙一块儿.走过林荫道,走到外面的梧桐树下。那儿.有一个书摊.各种书都有.一本一本整齐地排列着。很多学生和老师在那儿,随意地翻着书。她笑笑.也站了下来.到处翻翻.她很爱看书。最后.拿起一套《欧·亨利小说集》.问书摊老板.多少钱。对方竖起一根指头,一套一百元。她摩挲了一下书.轻轻放下.走了。

RDW在4月龄内儿童β地中海贫血筛查中的应用研究

目的探讨红细胞体积分布宽度在4月龄内儿童筛查β地中海贫血的价值,并由此探讨改进新生儿地中海贫血筛查程序。方法回顾分析广东东莞地区1 196例4月龄内儿童静脉血样本,均进行全血细胞分析和基因验证,其中α、β地贫组各400例,常见α、β基因均阴性组396例。分别对3个组红细胞体积分布宽度标准差(RDW-SD)、分布宽度变异系数(RDWCV)进行对比,使用受试者工作曲线(ROC曲线)得出β地贫RDW-SD、RDW-CV的筛查诊断范围。结果α地贫、β地贫、阴性组静脉血样本RDW-CV值分别为17. 34±2. 40、20. 32±2. 77、15. 49±1. 68,RDW-SD值分别为46. 07±5. 23、60. 50±8. 63、49. 02±5. 99,各组差异均有统计学意义(P0. 05)。β、α地贫组RDW-CV最佳截断值18. 45,曲线下面积(AUC)为0. 797,灵敏度68. 8%,特异度74. 8%,约登指数(YI) 0. 435; RDW-SD最佳截断值53. 45,AUC 0. 917,灵敏度92. 5%,特异度86. 2%,YI 0. 788。β地贫组、阴性组RDW-CV最佳截断值17. 05,AUC 0. 942,灵敏度90. 0%,特异度88. 9%,YI 0. 789;RDW-SD最佳截断值54. 35,AUC 0. 879,灵敏度83. 8%,特异度84. 5%,YI 0. 683。α地贫组、阴性组RDW-CV最佳截断值16. 45,AUC 0. 745,灵敏度64. 3%,特异度82. 3%,YI 0. 466; RDW-SD最佳截断值48. 55,AUC 0. 666,灵敏度72. 3%,特异度55. 3%,YI 0. 276。结论 4月龄内儿童RDW-CV、RDW-SD能有效地将β地贫从α地贫和正常儿中区分。以MCV80fL和(或) MCH27 pg和(或) RDW-CV16. 45%为筛查条件筛查出可疑的α、β地贫患儿,如果怀疑是α、β地贫患儿可以RDWSD53. 45fL为条件得到可疑β地贫患儿,并行血红蛋白电泳,最终基因检测确诊。此筛查程序能更好的减少β地贫的遗漏,促进新生儿地贫筛查事业的发展,适合在基层医院推广。
