The specifical concentration of cholesterol could decrease the VECs genomic DNA methylation level.

一定浓度的胆固醇能降低血管内皮细胞中DNA甲基化水平。

Poly（p-vinylbenzyl succinimide） resin,which can be abbreviated to succinimide resin,was prepared by the reaction of chloromethylated polystyrene with succinimide in the presence of base. The succinimide resin was characterized by diffuse reflectance infrared Fourier transform spectrometry and elemental analysis.

摘 要：在碱性条件下，氯甲基化聚苯乙烯与丁二酰亚胺反应合成了聚（对乙烯基苄基丁二酰亚胺）树脂，采用元素分析、红外光谱对合成树脂的组成进行了表征。

This implies that DNA methylation of promoter exon 1_7 may not underly the mechanism of GR up-regulation in GLP-1 -programmed rats.5 Hippocampal expression of GLP-1R and NGFI-A mRNAHippocampal GLP-1R (p =.009) and NGFI-A (p =.001) gene mRNA expression were significantly up-regulated in GP group as compared to VP group.Taken together, neonatal intramuscular injection of plasmid DNA encoding GLP-1 affects behavior and hippocampal GR expression in adolescent rats.

提示GR exon 1_7启动子区域DNA甲基化可能不参与GLP-1导致的GR转录上调。6海马GLP-1R和NGFI-A mRNA表达GP组大鼠GLP-lR(P=。009)和NGFI-A(P=。001)表达均显著高于VP组，表明肌肉注射GLP-1可能通过作用于其海马受体提高NGFI-A表达，进而调控GR表达。

Therefore, the chemically-treated DNA sequence will differ only if it was originally unmethylated in vivo.
