结论人乳腺癌er基因的失活与其基因启动子高甲基化关系密切。
Conclusion the inactivation of er gene has a close relationship with the abnormal methylation of er gene promoter.
结论肝细胞癌中CHFR基因、EDNRB基因启动子的高甲基化是普遍现象，而3 - OST - 2基因启动子甲基化率较低。
Conclusion promoter methylation of CHFR and EDNRB genes is a common event in HCC, while frequency of promoter methylation of 3-ost-2 is rather low.
