DNA methylation and DNA methyltransferases [PDF]

open access: yesEpigenetics & Chromatin, 2017
The prevailing views as to the form, function, and regulation of genomic methylation patterns have their origin many years in the past, at a time when the structure of the mammalian genome was only dimly perceived, when the number of protein-encoding ...

DNA Methylation [PDF]

open access: yesEcoSal Plus, 2009
The DNA of Escherichia coli contains 19,120 6-methyladenines and 12,045 5-methylcytosines in addition to the four regular bases, and these are formed by the postreplicative action of three DNA methyltransferases. The majority of the methylated bases are formed by the Dam and Dcmmethyltransferases encoded by the

Methylation of DNA [PDF]

open access: yesThe Journal of General Physiology, 1966
The methylated bases of DNA are formed by the transfer of the methyl group from S-adenosylmethionine to a polynucleotide acceptor. This transfer is catalyzed by highly specific enzymes which recognize a limited number of available sites in the DNA. The mechanism for the recognition is presently unknown.

DNA Methylation in Osteoarthritis [PDF]

open access: yesCurrent Genomics, 2015
Osteoarthritis (OA) is a prevalent disease of articular joints and primarily characterized by degradation and calcification of articular cartilage. Presently, no effective treatment other than pain relief exists and patients ultimately need to undergo replacement surgery of the affected joint.

Apoptosis and DNA Methylation [PDF]

open access: yesCancers, 2011
Epigenetic mechanisms assist in maintaining gene expression patterns and cellular properties in developing and adult tissues. The molecular pathology of disease states frequently includes perturbation of DNA and histone methylation patterns, which can activate apoptotic pathways associated with maintenance of genome integrity.

Aging and DNA methylation [PDF]

open access: yesBMC Biology, 2015
In this Opinion article, we summarize how changes in DNA methylation occur during aging in mammals and discuss examples of how such events may contribute to the aging process. We explore mechanisms that could facilitate DNA methylation changes in a site-specific manner and highlight a model in which region-specific DNA hypermethylation during aging is ...

DNA methylation in insects [PDF]

open access: yesInsect Molecular Biology, 2004
AbstractCytosine DNA methylation has been demonstrated in numerous eukaryotic organisms and has been shown to play an important role in human disease. The function of DNA methylation has been studied extensively in vertebrates, but establishing its primary role has proved difficult and controversial.

Guiding DNA Methylation [PDF]

open access: yesCell Stem Cell, 2011
How DNA methyltransferases, with their limited target specificity, establish cell-type-specific epigenetic patterns is poorly understood. Schübeler and colleagues (Lienert et al., 2011) now show that methylation-determining regions (MDRs) within promoter regions are sufficient to recapitulate endogenous patterns and dynamics of DNA methylation.

Methylated DNA Immunoprecipitation [PDF]

open access: yesJournal of Visualized Experiments, 2009
The identification of DNA methylation patterns is a common procedure in the study of epigenetics, as methylation is known to have significant effects on gene expression, and is involved with normal development as well as disease. Thus, the ability to discriminate between methylated DNA and non-methylated DNA is essential for generating methylation ...

Co-targeting RNA Polymerases IV and V Promotes Efficient De Novo DNA Methylation in Arabidopsis. [PDF]

open access: yes, 2019
The RNA-directed DNA methylation (RdDM) pathway in plants controls gene expression via cytosine DNA methylation. The ability to manipulate RdDM would shed light on the mechanisms and applications of DNA methylation to control gene expression.
