DNAmod: the DNA modification database [PDF]
Covalent DNA modifications, such as 5-methylcytosine (5mC), are increasingly the focus of numerous research programs. In eukaryotes, both 5mC and 5-hydroxymethylcytosine (5hmC) are now recognized as stable epigenetic marks, with diverse functions ...

Context-dependent DNA polymerization effects can masquerade as DNA modification signals [PDF]
Background Single molecule measurements of DNA polymerization kinetics provide a sensitive means to detect both secondary structures in DNA and deviations from primary chemical structure as a result of modified bases.

In vivo mutational characterization of DndE involved in DNA phosphorothioate modification. [PDF]
DNA phosphorothioate (PT) modification is a recently identified epigenetic modification that occurs in the sugar-phosphate backbone of prokaryotic DNA. Previous studies have demonstrated that DNA PT modification is governed by the five DndABCDE proteins ...

TET3-mediated accumulation of DNA hydroxymethylation contributes to the activity-dependent gene expression of Rab3a in post-mitotic neurons [PDF]
Rab3a, a subtype protein in the Rab3 family amongst the small G proteins, is closely associated with the learning and memory formation process. Various neuronal stimuli can induce the expression of Rab3a; however, how DNA modification is involved in ...

Traditional Chinese Medicine: A Class of Potentially Reliable Epigenetic Drugs
Epigenetic modification, especially DNA methylation, plays a nonnegligible role in the occurrence and development of tumors. Increasing studies are indicating that traditional Chinese medicine (TCM) plays a considerable anti-tumor role by regulating the ...

5hmC modification regulates R-loop accumulation in response to stress
R-loop, an RNA-DNA hybrid structure, arises as a transcriptional by-product and has been implicated in DNA damage and genomic instability when excessive R-loop is accumulated. Although previous study demonstrated that R-loop is associated with ten-eleven
