GenomicsHydroxylation of 5-methylcytosine by TET2 maintains the active state of the mammalian HOXA cluster (MeDIP-Seq)
Differentiation is accompanied by extensive epigenomic reprogramming, leading to the repression of stemness factors and the transcriptional maintenance of activated lineage-specific genes. Here we used the mammalian Hoxa cluster of developmental genes as a model system to follow changes in DNA modif...

GenomicsGenome-wide analysis reveals TET- and TDG-mediated 5-methylcytosine oxidation dynamics [MeDIP-Seq]
Ten-eleven translocation (Tet) family of DNA dioxygenases converts 5-methylcytosine (5mC) into 5-hydroxymethylcytosine (5hmC), 5-formylcytosine (5fC), and 5- carboxylcytosine (5caC) through iterative oxidation reactions. While 5mC and 5hmC are relatively abundant, 5fC and 5caC are at very low levels...

GenomicsEffects of dynamic cytosine methylation on alternative pre-mRNA splicing in T lymphocytes
Intragenic 5-methylcytosine and CTCF mediate opposing affects on pre-mRNA splicing: CTCF promotes inclusion of weak upstream exons through RNA polymerase II pausing, whereas 5-methylcytosine evicts CTCF, leading to exon exclusion. However, the mechanisms governing dynamic DNA methylation at CTCF bin...

GenomicsWhole-genome analysis of 5-hydroxymethylcytosine and 5-methylcytosine at base resolution in the human brain
5-Hydroxymethylcytosine (hmC) is particularly abundant in mammalian brains with yetto be revealed functions. Here, we present genome-wide and single-base-resolutionmaps of hmC and mC in the human brain. We demonstrated that hmCs increasemarkedly from the fetal to the adult stage, and in the adult br...

ProteomicsMETTL8 is required for 3-methylcytosine modification in human mitochondrial tRNAs
A subset of eukaryotic tRNAs is methylated in the anticodon loop to form the 3-methylcytosine (m3C) modification. In mammals, the number of tRNAs containing m3C has expanded to include mitochondrial (mt) tRNA-Ser-UGA and mt-tRNA-Thr-UGU. Whereas the enzymes catalyzing m3C formation in nuclear-encode...

TranscriptomicsDistinct roles of Tet1 and Tet2 in mouse embryonic stem cells (RNA-Seq)
The TET proteins TET1, TET2 and TET3 constitute a new family of dioxygenases that utilize molecular oxygen and the cofactors Fe(II) and 2-oxoglutarate to convert 5-methylcytosine (5mC) to 5-hydroxy-methylcytosine (5hmC) and further oxidation products in DNA1-5. Here we show that Tet1 and Tet2 have d...
