Mechanism of Crosstalk between m6A Modification and Epigenetic Regulation
Crosstalk ID
M6ACROT00054
[1]
RNA modification METTL3 METTL3 ALKBH3 Demethylation : modification sites Indirect Enhancement m6A modification COL1A1 COL1A1 YTHDF1 : m6A sites
m6A Modification:
m6A Regulator YTH domain-containing family protein 1 (YTHDF1) READER
m6A Target Collagen alpha-1 (COL1A1)
Epigenetic Regulation that have Cross-talk with This m6A Modification:
Epigenetic Regulation Type RNA modification (RNAMod)  >> N1-methyladenosine (m1A)
Epigenetic Regulator Alpha-ketoglutarate-dependent dioxygenase alkB homolog 3 (ALKBH3) ERASER View Details
Regulated Target Methyltransferase-like protein 3 (METTL3) View Details
Crosstalk Relationship m1A  →  m6A Enhancement
Crosstalk Mechanism RNA modification indirectly impacts m6A modification through downstream signaling pathways
Crosstalk Summary ALKBH3 recognizes the m1A methylation sites and prevents YTHDF2-dependent mRNA decay of Methyltransferase-like protein 3 (METTL3) transcript. Subsequently, METTL3 stabilizes Collagen alpha-1 (COL1A1) and FN1 mRNAs in a YTHDF1-dependent manner, two major components of extracellular matrix, and therefore eliciting the pathological transformation of HTS. This observation bridges the understanding of the link between m1A and m6A methylation, the two fundamental RNA modifications, underscoring the participation of "RNA methylation crosstalk" in pathological events.

In-vivo Model Six- to eight-week-old C57BL/6 mice were purchased from Cyagen Biosciences, Inc. (Cyagen, Suzhou, China). Alkbh3/ C57BL/6 mice were generated via the CRISPR/Cas9 system. Single-guide RNAs (sgRNAs) were designed to target exons 3 to 5 of Alkbh3 and were coinjected with Cas9 into the zygotes. The pups obtained were genotyped by PCR. After genotyping, the F0 mice were subjected to serial mating to generate homozygous mutant offspring.
