Term Name:	positive regulation of gene expression via chromosomal CpG island demethylation
Synonyms:	DNA demethylation, DNA hypomethylation of CpG island, hypomethylation of CpG island, positive regulation of gene expression via chromosomal CpG dinucleotide demethylation
Definition:	An epigenetic gene regulation mechanism that positively regulates gene expression by demethylation of cytosine residues in chromosomal CpG islands. CpG islands are genomic regions that contain a high frequency of the CG dinucleotide and are often associated with the transcription start site of genes.
