DNA hydroxylation catalyzed by Tet dioxygenases occurs abundantly in embryonic stem cells and neurons in mammals. However, its biological function in vivo is largely unknown. Here, we demonstrate that Tet1 plays an important role in regulating neural progenitor cell proliferation in adult mouse brain. Mice lacking Tet1 exhibit impaired hippocampal(More)
DNA methylation and histone modification are two major epigenetic pathways that interplay to regulate transcriptional activity and other genome functions. Dnmt3L is a regulatory factor for the de novo DNA methyltransferases Dnmt3a and Dnmt3b. Although recent biochemical studies have revealed that Dnmt3L binds to the tail of histone H3 with unmethylated(More)
Tet-mediated DNA oxidation is a recently identified mammalian epigenetic modification, and its functional role in cell-fate transitions remains poorly understood. Here, we derive mouse embryonic fibroblasts (MEFs) deleted in all three Tet genes and examine their capacity for reprogramming into induced pluripotent stem cells (iPSCs). We show that(More)
