Epigenetic alterations including DNA methylation and microRNAs (miRNAs) play important roles in the initiation and progression of human cancers. As the extensively studied epigenetic changes in tumors, DNA methylation and miRNAs are the most potential epigenetic biomarkers for cancer diagnosis. After the identification of circulating cell-free nuclear acids, increasing evidence demonstrated great potential of cell-free epigenetic biomarkers in the blood or other body fluids for cancer detection.
包括DNA甲基化和微小RNA(miRNA)在内的表观遗传改变在人类癌症的发生和发展中起着重要作用。作为肿瘤中广泛研究的表观遗传变化,DNA甲基化和miRNA是癌症诊断中最具潜力的表观遗传生物标志物。在循环游离核酸被发现后,越来越多的证据表明血液或其他体液中的游离表观遗传生物标志物在癌症检测方面具有巨大潜力。
