  • DMR indicates differentially methylation region.

  • Each Me-RDA clone represents a distinct Hin6I orHpaII fragment or CpG island library clone. In many cases, the clones were isolated many times.

  • GenBank accession nos. indicate the best BLASTN matches with database sequences; more than one entry is given for similar BLASTN scores. No GenBank accession is given for Slc38a4 as the DPC and CPGC were not within GenBank database sequence.
