Scientists from Japan developed methylation-specific fluorescence in situ hybridization (MeFISH) for microscopic visualization of DNA methylation status at specific repeat sequences in individual cells. MeFISH is based on the differential…
…of North Carolina at Chapel Hill conducted a study which examined the relationship between CpG-specific cord blood DNA methylation and birth weight. Using the Infinium HumanMethylation450 BeadChip (Illumina, Inc., San…
…DNA by inferring methylation patterns “using post-mortem damage to cytosines as a proxy for cytosine methylation levels.” But this method is clearly limited in its ability to precisely assess DNA…
…potentially reducing health disparities. DNA Methylation The most widely studied epigenetic mechanism is DNA methylation, primarily because it is stable and can be feasibly analyzed on a large scale. DNA…
…epigenetics, and health benefits. DNA Methylation Studies DNA methylation is a well-researched epigenetic modification that involves adding a 5-carbon to DNA’s cytosine ring via DNA methyltransferases. It’s vital for gene…
…DNA fragments can be analyzed. Early aDNA studies were mostly restricted to mitochondrial DNA (mtDNA). One reason for this is because a cell has hundreds of copies of mtDNA. In…
…can thus be utilized to determine the exact source from which the cfDNA originated. For example, hypomethylation of CpG motifs in the insulin promoter distinguishes β-cell-derived cfDNA from non-β-cell DNA…
DNA bisulfite conversion is a unique tool used to discriminate between methylated and unmethylated cytosines for DNA methylation studies. Only bisulfite modification of DNA followed by sequencing yields reliable information…
…of CpG methylation and methylation abnormalities in DNA via bisulfite sequencing has become overwhelmingly popular – and interest continues to grow. The unparalleled power of next-generation sequencing (NGS) platforms provides…
…effective treatments. DNA Methylation DNA methylation and hydroxymethylation are fundamental processes implicated in AD. DNA methylation involves the addition of a methyl group (5mC) to DNA, which typically results in…
