CHFR基因在癌组织和癌旁组织的甲基化率分别为52.5%和27.5%，癌组织中的甲基化率高于癌旁组织(P.05)。

Currently, we are developing a more global methodology for fishing out tissue- and developmental stage-specific methylated sites.

现在，我们更进一步发展出更能广泛地在基因组中寻找甲基化片段以期待能够找出更多的组织特异性和不同时其的甲基化片段。

Synthetic technology of 2,6-dimethylnaphthalene (2,6-DMN) by adopting the transmethylation method using methylnaphthalene as raw material was studied in this paper.

研究了以甲基萘为原料采用转移甲基化法合成2，6-二甲基萘(2，6-DMN)的工艺条件。

The promoter and partial GAG domain of CFG1 element are unmethylated, however, the partial RT domain is highly methylated.

CFG1元件的启动子和部分组特异性抗原域处于未甲基化状态，而部分RT域则处于高度甲基化状态。

Some stimulators, including viruses, tumor cells and hot shock, could promote the expression of NKG2 receptors and their ligands via activating certain transcription factors which are capable of up-regulating NKG2 promoters' activity. Meanwhile, epigenetic mechanisms including DNA methylation and histone posttranslational modifications are also critical to expression of NKG2 receptors and their ligands and may control the clonally distribution of some NK cell receptors.

病毒、肿瘤和热休克等刺激可以通过激活相应的转录调节因子，提高启动子活性而上调NKG2家族受体及其配体的表达，而启动子区DNA的甲基化状态、组蛋白的乙酰化和甲基化等表观遗传调控，在NK细胞受体及其配体的表达方面亦起重要作用，并决定NK细胞受体的克隆性分布。

The investigation of cells of bronchial lavages with lung cancer showed hypermethylation of at least one gene in squamous cell carcinoma, adenocarcinoma, small cell lung cancer and adenosquamous carcinoma is 17/23(73.9%),13/20(65.0%),4/5 and 2/3, respectively.

51例肺癌患者中，支气管灌洗液和上清研究过甲基化结果如下：对灌洗液细胞进行三种基因过甲基化研究诊断鳞癌、腺癌、小细胞癌和腺鳞癌的阳性比例分别为17/23(73.9%)，13/20(65.0%)，4/5，2/3。

SLC5A8 gene expression level in 42 cases of GCA was detected with RT-PCR method.
