1. A method comprising:
- administering to a subject, an agent that modulates activity of an enzyme that mediates conversion of a methylated cytosine residue to a modified base, wherein said subject has a cancer or is at risk of developing said cancer, wherein said modified base comprises a hydroxymethylated cytosine residue.

Abstract
The present invention provides for novel methods for regulating and detecting the cytosine methylation status of DNA. The invention is based upon identification of a novel and surprising catalytic activity for the family of TET proteins, namely TET1, TET2, TET3, and CXXC4. The novel activity is related to the enzymes being capable of converting the cytosine nucleotide 5-methylcytosine into 5-hydroxymethylcytosine by hydroxylation.
