DNA甲基化是最早发现的基因表观修饰方式之一,真核生物中的甲基化仅发生于胞嘧啶,即在DNA甲基化转移酶(DNMTs)的作用下使CpG二核苷酸5’-端的胞嘧啶转变为5’-甲基胞嘧啶。DNA甲基化通常抑制基因表达,去甲基化则诱导了基因的重新活化和表达。
这里,我们概述了当前用于甲基化检测的试剂,及它们在微阵列和测序平台上的应用。
Here, we outline the currently used methylation detection reagents and their application to microarray and sequencing platforms.
结果:在最小限度的假阴性及假阳性结果中,TLX3和FOXE3 DNA甲基化检测可有效鉴别ALL。
Results: Reliable detection of DNA methylation of TLX3 and FOXE3 segregated ALL from those clear of disease with minimal false-negative and false-positive results.
对人体DNA甲基化水平进行检测发现,结合在DNA上的甲基团数量与年龄有关,因此,唾沫分析技术有望成为犯罪现场取证工具。
An analysis of a person's DNA methylation finds that the number of methyl groups attached to the DNA correlates with the person's age — making saliva analysis a possible CSI tool.
