将整个基因组划分为Promoter,Body,3UTR,Intergenic4种区域,其中Promoter区又细分为TSS200,TSS1500,5UTR, ‘1stExon’ 4种情况。 可以看到,位于Pronoter区的探针最多 在各种CpG区域的分布 CpG shores等概念是根据与CpG island的距离进行定义的。CpG Shores指的是位于CpG island上下游2kb 以内的区域;CpG Shelves指...
are transcriptionally silent was overturned by the discovery that DNA-dependent RNA polymerase II (RNAPII) transcribes telomeric DNA into telomeric repeat-containing RNA (TERRA). Here, we show that CpG dinucleotide-rich DNA islands, shared among multiple human chromosome ends, promote transcription...

CpG island promoter hypermethylation of the Ras-effector gene NORE1A occurs in the context of a wild-type K-ras in lung cancerCpGIslandsMethylationHumanCpG岛甲基化Imbalance of the Ras signaling pathway is a major hallmark of human cancer. In this context, activating point mutations of the K-...
We performed MethyLight analysis for the methylation status of 57 promoter CpG island loci in 20 IDCs and their paired normal breast tissues. After selecting 15CpG island loci showing breast cancer-specific DNA methylation, another set of normal breast tissue (n=10), ADH/FEA (n=30), DCIS (...
其实我也是这么认为，一旦promoter或者exon1的CpG island发生了高度甲基化，那么这个基因表达就会受抑制，...
