DNA Methylation
- Where
5 position of the pyrimidine ring of cytosines in the context of the dinucleotide sequence CpG
- How
- Response to stimuli
diet toxins
- Aberrant DNA methylation
Leads to cancer - where genome wide hypomethylation coincides with gene-specific hypermethylation
- Usage
The epigenetic mechanisms controlling and modulating gene expression through chromatin structure Closely interacts with histone modifications and chromatin-remodeling complexes to form the genomic chromatin landscape Essential for proper mammalian development Crucial for imprinting Plays a role in maintaining genomic stability and dosage compensation Used to detect cancer at very early stages
