Crosstalk Relationship m6A  →  DNA methylation Enhancement
Crosstalk Mechanism m6A modification indirectly regulates DNA methylation through downstream signaling pathways
Crosstalk Summary After ANKRD13C divergent transcript (ANKRD13C-DT) is methylated by METTL3, RNA N6-methyladenosine (m6A) reader, YTHDC2, occupies genomic loci of the primate-specific TE, Long Terminal Repeat 7 (LTR7)/HERV-H, specifically through its interaction with m6A-modified HERV-H RNAs. Unexpectedly, YTHDC2 recruits the DNA 5-methylcytosine (5mC)-demethylase, TET1, to remove 5mC from LTR7/HERV-H and prevent epigenetic silencing. Functionally, the YTHDC2/LTR7 axis inhibits neural differentiation of hESCs.
