analysis
-
use of recombinant enzyme to estimate global 5-hydroxymethyl cytosine content in a variety of genomic DNAs. Most of the genomic DNAs derived from vertebrate tissue and cell lines contain 5-hydroxymethyl cytosine. DNA from mouse, human, and bovine brains displays 0.5?0.9% of the total nucleotides as 5-hydroxymethyl cytosine, which is higher compared to the levels found in other tissues. A comparison between cancer and healthy tissue genomes suggests a lower percentage of 5-hydroxymethyl cytosine in cancer
