DNA Methylation
One of the fastest growing fields in biology and cancer research isepigenetics. While the underlying genetic code defines which proteins and geneproducts are synthesized, it is epigenetic control that defines when and wherethey are expressed. This dynamic control of gene expression is essential for Xchromosome inactivation, embryogenesis, cellular differentiation and appearsintegral to memory formation and synaptic plasticity.
In 2009, two reports1,2 described the discovery of5-hydroxymethyl-2’-deoxyCytidine (hmdC), a novel dC modification in Purkinjeneurons and embryonic stem cells. Later, a third report found this modificationto be strongly enriched in brain tissues associated with higher cognitivefunctions.3 This new dC modification is generated by the action ofa-ketoglutarate dependent TET enzymes (ten eleven translocation), which oxidizes5-Me-dC to hmdC. This finding stimulated discussion about active demethylationpathways that could occur, e.g., via base excision repair (BER), with the helpof specialized DNA glycosylases. Alternatively, one could envision a process inwhich the hydroxymethyl group of hmdC is further oxidized to 5-formyl-dC (fdC)or 5-carboxy-dC (cdC) followed by elimination of either formic acid or carbondioxide4,5.
Glen Research has supported this research since its inception by providingthe building blocks for the synthesis of oligonucleotides containing all the newdC derivatives - hmdC, fdC and cdC. The first generation hmdC phosphoramiditewas fairly very well accepted but requires fairly harsh deprotection conditions.Therefore, a second generation building block (5-Hydroxymethyl-dC II) developedby Carell and co-workers that is compatible with UltraMild deprotection has beenintroduced.6 A second generation fdC-phosphoramidite (5-Formyl-dCII), also developed by Carell and co-workers, has been introduced since it doesnot require the post synthesis elimination step of the first generationversion.7
5-Formyl-dC and 5-carboxy-dC may find uses in research into DNA damage andrepair processes.
