DNA methylation, one of the most studied epigenetic modifications, refers to the addition of a methyl group to the fifth carbon of cytosine (C) catalyzed by DNA methyltransferases(Dnmts), forming 5-methylcytosine (5mC). DNA methylation predominantly occurs inCpGs but is also found in non-CpG contexts.

Decreased DNA methylation of a CpG site in the HBAP1 gene in plasma DNA from pregnant women. [PDF]
OBJECTIVE:The objective of this study is to identify potential CpG site(s) or DNA methylation pattern(s) in the pseudo α-globin 1 gene (HBAP1 gene), the gene which locates in α-thalassemia-1 deletion mutation, to differentiate plasma DNA between pregnant

Role of genetic and environmental factors in DNA methylation of lipid metabolism
A number of recent studies revealed that DNA methylation plays a central role in the regulation of lipid metabolism. DNA methylation modifications are important regulators of transcriptional networks that do not affect the DNA sequence and can translate ...

In utero tobacco smoke exposure, DNA methylation, and asthma in Latino children. [PDF]
BackgroundMaternal smoking during pregnancy is a risk factor for chronic disease later in life and has been associated with variability of DNA methylation at specific cytosine-phosphate-guanine (CpG) loci.

Methylation of chromatin DNA [PDF]
E. coli DNA methylase has been used to methylate chromatin DNA in vitro. At saturation only 50% of the chromatin DNA becomes methylated. The methylated regions of chromatin correspond to that fraction of the chromatin which is sensitive to staphylococcal nuclease.

Summary: DNA methylation plays crucial roles in chromatin structure and gene expression. Aberrant DNA methylation patterns, including global hypomethylation and regional hypermethylation, are associated with cancer and implicated in oncogenic events. How

DNA methylation arrays as surrogate measures of cell mixture distribution
There has been a long-standing need in biomedical research for a method that quantifies the normally mixed composition of leukocytes beyond what is possible by simple histological or flow cytometric assessments.
