Abstract: N6-methyladenosine (m6A) is involved in most biological processes and actively participates in the regulation of reproduction. According to recently research, long non-coding RNAs (lncRNAs) and their m6A modifications are involved in reproductive diseases. In the present study, using m6A modified RNA immunoprecipitation sequencing (m6A-seq), the m6A methylation transcription profiles in recurrent implantation failure (RIF) were established for the first time. 1443 significantly up-regulated m6A peaks and 425 significantly down-regulated m6A peaks were identified in RIF. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis revealed that genes associated differentially methylated lncRNAs were involved in classical p53 signaling pathway and amino acid metabolism. Then, competing endogenous RNA (ceRNA) network revealed a regulatory relationship between lncRNAs, microRNAs (miRNAs) and mRNAs. The m6A methylation abundances of lncRNAs were verified by m6A-RNA immunoprecipitation (MeRIP)-qPCR in this study. This study will lay a foundation for further exploration of the potential role of m6A modification in the pathogenesis of RIF.
