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.
