background tet enzymes mediate dna demethylation by oxidizing 5-methylcytosine (5mc) in dna to 5-hydroxymethylcytosine (5hmc), 5-formylcytosine (5fc), and 5-carboxylcytosine (5cac). since these oxidized methylcytosines (oxi-mcs) are not recognized by the maintenance methyltransferase dnmt1, dna demethylation can occur through “passive,” replication-dependent dilution when cells divide. a distinct, replication-independent (“active”) mechanism of dna demethylation involves excision of 5fc and 5cac by the dna repair enzyme thymine dna glycosylase (tdg), followed by base excision repair. results here by analyzing inducible gene-disrupted mice, we show that dna demethylation during primary t cell differentiation occurs mainly through passive replication-dependent dilution of all three oxi-mcs, with only a negligible contribution from tdg. in addition, by pyridine borane sequencing (pb-seq), a simple recently developed method that directly maps 5fc/5cac at single-base resolution, we detect the accumulation of 5fc/5cac in tdg-deleted t cells. we also quantify the occurrence of concordant demethylation within and near enhancer regions in the il4 locus. in an independent system that does not involve cell division, macrophages treated with liposaccharide accumulate 5hmc at enhancers and show altered gene expression without dna demethylation; loss of tet enzymes disrupts gene expression, but loss of tdg has no effect. we also observe that mice with long-term (1 year) deletion of tdg are healthy and show normal survival and hematopoiesis. conclusions we have quantified the relative contributions of tet and tdg to cell differentiation and dna demethylation at representative loci in proliferating t cells. we find that tet enzymes regulate t cell differentiation and dna demethylation primarily through passive dilution of oxi-mcs. in contrast, while we observe a low level of active, replication-independent dna demethylation mediated by tdg, this process does not appear to be essential for immune cell activation or differentiation.

tet offensive, attacks staged by north vietnamese forces beginning in the early hours of january 31, 1968, during the vietnam war. the attacks were carried out by some 85,000 troops against five major south vietnamese cities, dozens of military installations, and scores of towns and villages throughout south vietnam.

ten-eleven translocation (tet) family proteins (tets), specifically, tet1, tet2 and tet3, can modify dna by oxidizing 5-methylcytosine (5mc) iteratively to yield 5-hydroxymethylcytosine (5hmc), 5-formylcytosine (5fc), and 5-carboxycytosine (5cac), and then two of these intermediates (5fc and 5cac) can be excised and return to unmethylated cytosines by thymine-dna glycosylase (tdg)-mediated base excision repair. because dna methylation and demethylation play an important role in numerous biological processes, including zygote formation, embryogenesis, spatial learning and immune homeostasis, the regulation of tets functions is complicated, and dysregulation of their functions is implicated in many diseases such as myeloid malignancies. in addition, recent studies have demonstrated that tet2 is able to catalyze the hydroxymethylation of rna to perform post-transcriptional regulation. notably, catalytic-independent functions of tets in certain biological contexts have been identified, further highlighting their multifunctional roles. interestingly, by reactivating the expression of selected target genes, accumulated evidences support the potential therapeutic use of tets-based dna methylation editing tools in disorders associated with epigenetic silencing. in this review, we summarize recent key findings in tets functions, activity regulators at various levels, technological advances in the detection of 5hmc, the main tets oxidative product, and tets emerging applications in epigenetic editing. furthermore, we discuss existing challenges and future directions in this field.
