Examination of the specificity of DNA methylation profiling techniques towards 5-methylcytosine and 5-hydroxymethylcytosine
DNA cytosine-5 methylation is a well-studied epigenetic pathway implicated in gene expression control and disease pathogenesis. Different technologies have been developed to examine the distribution of 5-methylcytosine (5mC) in specific sequences of the genome. Recently, substantial amounts of 5-hydroxymethylcytosine (5hmC), most likely derived from enzymatic oxidation of 5mC by TET1, have been...
متن کاملCrystal structures of B-DNA dodecamer containing the epigenetic modifications 5-hydroxymethylcytosine or 5-methylcytosine
5-Hydroxymethylcytosine (5-hmC) was recently identified as a relatively frequent base in eukaryotic genomes. Its physiological function is still unclear, but it is supposed to serve as an intermediate in DNA de novo demethylation. Using X-ray diffraction, we solved five structures of four variants of the d(CGCGAATTCGCG) dodecamer, containing either 5-hmC or 5-methylcytosine (5-mC) at position 3...
متن کاملOxidative damage to 5-methylcytosine in DNA.
Exposure of pyrimidines of DNA to ionizing radiation under aerobic conditions or oxidizing agents results in attack on the 5,6 double bond of the pyrimidine ring or on the exocyclic 5-methyl group. The primary product of oxidation of the 5,6 double bond of thymine is thymine glycol, while oxidation of the 5-methyl group yields 5-hydroxymethyluracil. Oxidation of the 5,6 double bond of cytosine ...
متن کاملSensitivity And Specificity Of Procalcitonin In Diagnosis Of Neonatal Sepsis
Background and Objective: According to the fact that neonatal infection is a challenging diagnosis field, several studies have tried to test sensitivity and specificity of diagnostic tests. This study was conducted to evaluate the sensitivity and specificity of procalcitonin (PCT) as a single early marker of neonatal sepsis. Materials and Methods: In this study, 150 neonates admitted to NIC...
متن کاملDetermination of DNA sequences containing methylcytosine in Bacillus subtilis Marburg.
The methylcytosine-containing sequences in the DNA of Bacillus subtilis 168 Marburg (restriction-modification type BsuM) were determined by three different methods: (i) examination of in vivo-methylated DNA by restriction enzyme digestion and, whenever possible, analysis for methylcytosine at the 5' end; (ii) methylation in vitro of unmethylated DNA with B. subtilis DNA methyltransferase and de...
