Methylation at position 5 of cytosine in DNA is being intensively studied in many areas of biological sciences, as the methylation is intimately associated with the control of gene functions. The principal analytical method for determining the sites of 5-methylcytosine in genome at the sequence level involves bisulfite modification of DNA. The utility of this chemical treatment is based on the ...
OBJECTIVE Prader-Willi Sydrome (PWS) is a human disorder related to genomic imprinting defect on 15q11-13. It is characterized by a series of classic features such as hypotonia, hyperphagia, obesity, osteoporosis, typical facial and body dysmorphosis, hypogonadism, mental and behaviour disorders. Our study was designed to precisely detect the microdeletions, which accounts for 65%-70% of the PW...
Although CpG methylation clearly distributes genome-wide in vertebrate nuclear DNA, the state of methylation in the vertebrate mitochondrial genome has been unclear. Several recent reports using immunoprecipitation, mass spectrometry, and enzyme-linked immunosorbent assay methods concluded that human mitochondrial DNA (mtDNA) has much more than the 2 to 5% CpG methylation previously estimated. ...
DNA methylation stabilizes developmentally programmed gene expression states. Aberrant methylation is associated with disease progression and is a common feature of cancer genomes. Presently, few methods enable quantitative, large-scale, single-base resolution mapping of DNA methylation states in desired regions of a complex mammalian genome. Here, we present an approach that combines array-bas...
