【摘要】 随着表观遗传学中DNA甲基化的深入研究,人们发现CpG岛(CpG island)DNA甲基化在结直肠癌(colorectal cancer,CRC)的临床诊断中发挥重要作用。目前,研究证实检测CRC患者组织、粪便和血液中基因的异常甲基化在CRC的早期筛查和诊断中具有很高的敏感性和特异性。本文就胞裂蛋白9(septin 9,SEPT9)、多配体聚糖2前体(syndecan 2 precursor,SDC2)、波形蛋白(vimentin,VIM)、p16和长散布核苷酸元件-1 (long interspersed nucleotide element-1,LINE-1)5个基因的甲基化及其在CRC诊断中的相关进展进行了综述。更多还原

【Abstract】 With the development of research on DNA methylation in epigenetics, Cp G island DNA methylation has been found to play an important role in the clinical diagnosis of colorectal cancer(CRC). At present, numerous researches have confirmed that the detection of abnormal methylation of genes in tissues, stool and blood of CRC patients has high sensitivity and specificity for early CRC screening and diagnosis. This review summarizes the methylation of five genes which have been investigated clearly, including septin 9(SEPT9), syndecan 2 precursor(SDC2), vimentin(VIM), p16, and long interspersed nucleotide element-1(LINE-1), and their progress in diagnosis of CRC.更多还原
