Underestimated effect of intragenic HIV-1 DNA methylation on viral transcription in infected individuals [PDF]
, 2020 Background: The HIV-1 proviral genome harbors multiple CpG islands (CpGIs), both in the promoter and intragenic regions. DNA methylation in the promoter region has been shown to be heavily involved in HIV-1 latency regulation in cultured cells.

DNA methylation arrays as surrogate measures of cell mixture distribution
BMC Bioinformatics, 2012 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.

Swiss Medical Weekly, 2013 DNA methylation, the addition of a methyl group to cytosines and adenosines, regulates gene expression on a level that is usually referred to as epigenetic, that is, stably maintained during cell divisions. In humans, aberrant DNA methylation is associated with several malignancies, including cancer and so-called imprinting disorders, making it an ...

Methylation of chromatin DNA [PDF]
Nucleic Acids Research, 1976 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.

Scientific Reports, 2021 Targeted DNA methylation is a technique that aims to methylate cytosines in selected genomic loci. In the most widely used approach a CG-specific DNA methyltransferase (MTase) is fused to a sequence specific DNA binding protein, which binds in the ...

Maternal nutritional status, C1 metabolism and offspring DNA methylation: a review of current evidence in human subjects. [PDF]
, 2011 : Evidence is growing for the long-term effects of environmental factors during early-life on later disease susceptibility. It is believed that epigenetic mechanisms (changes in gene function not mediated by DNA sequence alteration), particularly DNA ...

Exploring genome wide bisulfite sequencing for DNA methylation analysis in livestock: a technical assessment [PDF]
, 2014 peer-reviewedRecent advances made in “omics” technologies are contributing to a revolution in livestock selection and breeding practices. Epigenetic mechanisms, including DNA methylation are important determinants for the control of gene expression in ...

DNA Methylation and Atherosclerosis [PDF]
The Journal of Nutrition, 2002 DNA methylation is a major epigenetic modification of the genome that has the potential to silence gene expression. Recently, the role of epigenetic alteration as a distinct and crucial mechanism to regulate genes governing cell proliferation in atherosclerosis has emerged.

Decreased DNA methylation of a CpG site in the HBAP1 gene in plasma DNA from pregnant women. [PDF]
PLoS ONE, 2018 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

Integrative DNA methylome analysis of pan-cancer biomarkers in cancer discordant monozygotic twin-pairs [PDF]
, 2016 BACKGROUND: A key focus in cancer research is the discovery of biomarkers that accurately diagnose early lesions in non-invasive tissues. Several studies have identified malignancy-associated DNA methylation changes in blood, yet no general cancer ...
