CpG Island Mapping by Epigenome Prediction
CpG islands were originally identified by epigenetic and functional properties, namely, absence of DNA methylation and frequent promoter association. However, this concept was quickly replaced by simple DNA sequence criteria, which allowed for genome-wide annotation of CpG islands in the absence of large-scale epigenetic datasets. Although widely used, the current CpG island criteria incur sign...
متن کاملBidding the CpG island goodbye
Experiments on seven vertebrates suggest that identifying the locations of islands of non-methylated DNA provides more insights into evolutionarily-conserved epigenetic regulatory elements than studies of CpG islands.
متن کاملPredicting aberrant CpG island methylation.
Epigenetic silencing associated with aberrant methylation of promoter region CpG islands is one mechanism leading to loss of tumor suppressor function in human cancer. Profiling of CpG island methylation indicates that some genes are more frequently methylated than others, and that each tumor type is associated with a unique set of methylated genes. However, little is known about why certain ge...

متن کاملCpG island hypermethylation in human astrocytomas.
Astrocytomas are common and lethal human brain tumors. We have analyzed the methylation status of over 28,000 CpG islands and 18,000 promoters in normal human brain and in astrocytomas of various grades using the methylated CpG island recovery assay. We identified 6,000 to 7,000 methylated CpG islands in normal human brain. Approximately 5% of the promoter-associated CpG islands in the normal b...
