Book Chapter Description

Methylation of DNA at the 5′ carbon of cytosine (5mC) is a key epigenetic regulator of gene expression required for the proper development and function of the central nervous system. Observations of experience-dependent fl uctuations in the patterns of 5mC at neuronal gene enhancers, promoters and intragenic regions have prompted great interest in the role of DNA methylation mechanisms in the brain. In addition, the recent discovery of 5-hydroxymethylcytosine (5hmC), an oxidized derivative of 5mC that acts as a DNA demethylation intermediate has offered mechanistic insight into how these changes in 5mC levels are achieved. As a result, numerous techniques have now been adapted or newly developed to quantify and profi le 5mC and 5hmC in the genome. Here we describe a method using high performance liquid chromatography electrospray ionization tandem mass spectrometry with multiple reaction monitoring (HPLC-ESI-MS/MS-MRM) for the simultaneous detection and quantifi cation of global 5mC and 5hmC levels present in genomic DNA from nervous-system derived samples. HPLC-ESI-MS/MS-MRM analysis offers the highest levels of sensitivity, selectivity, and precision available for the determination of global changes in these epigenetic modifi cations.
