查询词典 methylation

DNA methyltransferases exhibit dual actions during these cycles, being involved in CpG methylation and active demethylation of 5mCpGs through deamination.

DNA甲基化同时通过脱氨出现在CpG和5mCpGs结构中。

Technologies for determining methylation patterns in cancer cells, Methyl Light and COBRA, both of which were based on the deamination of methylated cytosines—which converts these cytosines to uracil residues—and identification of the converted sequence by analytical methods.

在上世纪80年代期间，研究的主要方法是PCR和克隆，两者都不涉及甲基化内容，因此很快就被弃用了。90年代，Laird开发了两类技术去检测肿瘤细胞中的甲基化模式，MethylLight和COBRA，两者都是以甲基化胞嘧啶的脱氨作用（将胞嘧啶转化为尿嘧啶残基）以及通过分析方法鉴定修改的序列为基础。

Methylation production were hydrolyzed, deoxidize, then analyzed by GC-MS.

甲基化产物经酸水解、还原、乙酰化后用GC-MS联机分析。

首先，它是在有机化学和无机化学的相互渗透中发展起来的，此外，它还和一些相关学科具有密切联系。

Methylation of Y14 can be blocked by RS dipeptide phosphorylation.

此外，Y14的甲基化反应会被Y14之磷酸化抑制。

Here we report the first high-throughput and candidate sequence analyses of DNA methylation to investigate discordance for autoimmune disease in twins.

最近一些对自身免疫疾病(如系统性红斑狼疮，SLE)的某些调控基因的研究表明，遗传组成相同的双胞胎双方，其表型不一致与表观遗传学差异有关。

Statistical evaluation was performed by using x~2 test and Fishers exact test for enumeration data and independent t test for measurement data to assess relationship of methylation between pancreatic neoplasm.

在从胰腺炎、IPMN至胰腺癌的进程中，NPTX2基因高甲基化阳性率逐渐加深，提示NPTX2基因可能参与胰腺癌进展，其高甲基化导致的基因沉默可能是导致胰腺癌的原因之一。

DNA methylating inhibitor has been used in the study of epigenesis that caused by DNA methylation of plants.Also,it can be instead of low temperature treatment to induce flowering of plants,make flowering time earlier than usual.Further study and application in the improvement of plants will be continued.

DNA甲基化抑制剂已被用于因DNA甲基化引起的植物表观遗传研究中，同时它可以代替低温促进植物提早开花，并可能在植物性状改良中得到进一步的研究和应用。

Aberrant DNA methylation patterns go beyond the fields of epigenesis. Its mainly about a reaction of cytosine transformation into S-methylcytosine mediated by methyltransferases.

DNA甲基化是表遗传学上研究最深入的一种机制，是由甲基转移酶介导，将胞嘧啶变为S—甲基胞嘧啶的一种反应。

Objective］ The study aimed to detect the DNA methylation level in different chicken fetation stages.

［目的］检测鸡胚不同发育阶段时的DNA甲基化水平。
