亚硫酸氢盐测序法检测上皮钙黏蛋白甲基化的优化探讨
Study on optimization of E-cadherin methylation detection by modified bisulfite sequencing
摘要
Abstract
Objective To investigate the feasibility of the modified bisulfite sequencing method in the E-cad-herin methylation detection .Methods The genomic DNA was extracted from the kidney tissues of male F344 rats and chemically converted with bisulfite sodium .Then the specific sequence in the E-cadherin promoter region was am-plified by PCR .The screening and sequencing were performed by the blue-white spot screening .Results No methyla-tion change occurred at 26 CpG sites in the CpG islands of E-cadherin gene promoter in the kidney of male F344 rats . Conclusion The modified bisulfite sequencing method can obviously reduce the non-specific amplification ,improves the efficiency of PCR and is more suitable for the detection of gene methylation status .关键词
