Project description:Global m6A-modified mRNAs in the uterus of wild-type mouse were analyzed by using methylated RNA immunoprecipitation sequencing (MeRIP-seq)
Project description:Global m6A-modified mRNAs in wild-type mouse uterus on gestational day 4 were analyzed by using methylated RNA immunoprecipitation sequencing (MeRIP-seq)
Project description:Global m6A-modified mRNAs in undecidualized and decidualized primary human endometrial stromal cells were analyzed by using methylated RNA immunoprecipitation sequencing (MeRIP-seq)
Project description:The goal of the study was to identify those mRNAs that are m6A-modified in a Mettl3-dependent manner under DNA-damage condition in oncogene-expressing mouse embryonic fibroblasts
Project description:Roles of m6A-modified mRNA transcripts in the context of MI were preliminarily verified. In the context of m6A methylation, three hub mRNAs were validated to impact the process of apoptosis/angiogenesis. Our study provided theoretical basis and innovative targets for treatment of MI and paved the way for future investigations aiming at exploring upstream epigenetic mechanisms of pathogenesis after MI.
Project description:N6-methyladenosine (m6A) is the most abundant mRNA nucleotide modification and regulates critical aspects of cellular physiology and differentiation. m6A is thought to mediate its effects through a complex network of interactions between different m6A sites and three functionally distinct cytoplasmic YTHDF m6A-binding proteins (DF1, DF2, and DF3). In contrast to the prevailing model, we show that DF proteins bind the same m6A-modified mRNAs, rather than different mRNAs. Furthermore, we find that DF proteins do not induce translation in HeLa cells. Instead, the DF paralogs act redundantly to mediate mRNA degradation and cellular differentiation. The ability of DF proteins to regulate stability and differentiation becomes evident only when all three DF paralogs are simultaneously depleted. Our studies reveal a unified model of m6A function in which all m6A-modified mRNAs are subjected to the combined action of the YTHDF proteins in proportion to the number of m6A sites.
Project description:To further investigate the effect of high-fat diet on m6A modified expression profiles of mouse sperm RNA, we used whole-genome microarray expression profiles as a discovery platform to identify differential m6A modified genes under high-fat diet exposure. Male mice were fed normal chow (C) or 60% high-fat diet (HFD) from 5 weeks to 15 weeks old, and then sperm were obtained for Arraystar m6A-mRNA&lncRNA Epitranscriptomic Microarray. Results showed that hyper-methylated mRNAs were involved in multiple biological processes, including the "reproductive process," "gamete generation," and "spermatogenesis".
