Circulating cell-free DNA (cfDNA) are small DNA fragments found circulating in plasma or serum, as well as other bodily fluids. The cfDNA isolated from plasma usually contains fragments of about…
…much less DNA methylation, referred to as DNA hypomethylation, in the sun-exposed skin of older individuals. This reduced level of DNA methylation, however, was not detected in the older individuals…
…23, and 56, methylated at arginine 2 and lysines 4, 9, 27, 36, and 79, and phosphorylated at ser10, ser28, Thr3, and Thr11. Histone H4 is primarily acetylated at lysines…
…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…
…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…
…and results from the complex interaction between genes and environment. Many studies point to epigenetic modifications (DNA methylation and histone modifications) in mediating this interaction. References: Dayeh T, et…
…our body’s cells essentially contain the same genes, the expression of those genes is tissue-specific and tightly regulated by epigenetic factors like DNA methylation and histone modifications. The cfDNA epigenome…
…article by Fides Lay, Ph.D., DNA Methylation Solves Crimes, a DNA methylation-based assay could be used in forensic applications for age prediction, authentication of DNA samples, body fluid identification, and…
…histone acetylation and histone methylation, have the ability to remodel chromatin to make genes more or less accessible, influencing their expression. Other research suggests we may modify DNA methylation with…
…detected in DNA from one Neanderthal and one Denisovan from Serbia ranging from 50,000 and 130,000 years old, a Paleo-Eskimo from Greenland that was 4,000 years old, and a bison…
