DNA Methyltransferase Inhibitors and their Therapeutic Potential

Current Topics in Medicinal Chemistry, 2019
Aberrant DNA methylation at the 5-position of cytosine, catalyzed by DNA methyltransferases (DNMTs), is associated with not only various cancers by silencing of tumor suppressor genes but also other diseases.

DNA methyltransferases

Current Opinion in Cell Biology, 1994
Mammals have long been known to tag their DNA by the addition of methyl groups to cytosine residues. Only quite recently, however, has the functional significance of DNA methylation established a firm footing. Evidence now indicates that DNA methylation is essential for development, and is involved in both programmed and ectopic gene inactivation ...

Microassay for DNA methyltransferase

Journal of Biochemical and Biophysical Methods, 1991
A microassay for DNA methylase is described which can detect activity in as few as 50 tissue culture cells. The cells are lysed and incubated for 2 h at 37 degrees C with 3 microCi high specific activity [3H]AdoMet and 0.5 microgram poly[d(I-C).d(I-C)] in a volume of 23 microliters.

DNA Methyltransferases and DNA Damage

2022
Ever since the discovery of depletion of CG sites in mammalian genomes it has been clear that cytosine DNA methyltransferases (DNMTs) are linked to the rate at which mutations accumulate in DNA. Research in the intervening decades has shown that DNMTs influence mutation rates through the indirect consequences of methylation on the mechanism of mutation

Plant DNA methyltransferases

Plant Molecular Biology, 2000
DNA methylation is an important modification of DNA that plays a role in genome management and in regulating gene expression during development. Methylation is carried out by DNA methyltransferases which catalyse the transfer of a methyl group to bases within the DNA helix.

EcoRI DNA methyltransferase-DNA interactions

Biochemistry, 1992
We present a novel strategy with synthetic hemimethylated DNA substrates containing uracil for thymine and inosine for guanosine replacements and EcoRI DNA methyltransferase to characterize the importance of major groove hydrophobic groups to the sequence-specific modification of DNA.

DNA Methyltransferase Assays

2011
DNA methyltransferases are important enzymes and their inhibition has many potential applications. The investigation of DNA methyltransferases as well as screening for potential inhibitors requires specialized enzyme assays. In this chapter, we describe three DNA methyltransferase assays, each of them based on a different method: (1) An assay using ...

Sea urchin DNA methyltransferases

Cell Biophysics, 1989
DNA methyltransferase activities have been partially purified from unfertilized eggs and blastula nuclei of sea urchin embryos. Comparative studies, using different DNAs as substrates, show that the two preparations are most active on hemimethylated and single-strand DNA, but they methylate, though at a lower rate, also on double-strand DNA.

DNA Labeling Using DNA Methyltransferases

2016
DNA methyltransferases (MTases) uniquely combine the ability to recognize and covalently modify specific target sequences in DNA using the ubiquitous cofactor S-adenosyl-L-methionine (AdoMet). Although DNA methylation plays important roles in biological signaling, the transferred methyl group is a poor reporter and is highly inert to further ...
