DNMT3A and lymphoma: Fewer genes (252 overexpressed and 239 underexpressed) were shared between human PTCL and Dnmt3aΔ/Δ PTCL, suggesting that the transcriptome of lymphomas induced by loss of a single Dnmt3a allele more so resembles human disease than those that arise do to full inactivation of Dnmt3a (Fig 8A and 8B and S9 Table).
