Transcriptome-wide N6-methyladenosine modification profiling in patients with recurrent implantation failure (RIF)

ABSTRACT: Purpose:using m6A modified RNA immunoprecipitation sequence (m6A-seq), to establish the m6A methylation transcription profiles in recurrent implantation failure (RIF). Methods: GenSeq® Low Input Whole RNA Library Prep Kit (GenSeq, Inc.) was used to construct RNA libraries for IP and input samples by following the manufacturer's instructions. The library quality was evaluated using Agilent 2100 bioanalyzer and then sequenced in a NovaSeq platform (Illumina 6000). Result:using m6A modified RNA immunoprecipitation sequence (m6A-seq), methylated sites in mRNA,lncRNA and circRNA are identified. Conclusions: Our study revealed the m6A methylation landscape by MERIP sequencing.

MeRIP-seq of mRNAs in MEFs with or without nutrient starvation

Project description:To investigate the dynamic m6A modification during starvation-induced autophagy, we performed MeRIP-seq in MEFs with or without nutrient deprivation and identified the variations of m6A modification on mRNAs. Briefly, the total polyadenylated mRNAs in MEFs cultured with or without nutrient-deprived medium for 2 hours were isolated using RNAiso plus reagent (Takara) followed Dynabeads mRNA Purification Kit (Invitrogen). The m6A RNA immunoprecipitation was performed using GenSeq m6A RNA IP Kit. NEBNext Ultra II Directional RNA Library Prep Kit (NEB) was used for library generation. Each experiment was conducted in two biological replicates. Methylated sites on peaks were identified by MACS2 peak-calling software (Zhang et al., 2008). Differentially methylated sites were identified by diffReps (Shen et al., 2013) with default setting.

MeRIP sequencing analysis of BJAB cell line infected with EBV

Project description:Purpose: Evaluation of the m6A modification of EBV and BJAB transcripts during EBV infection Methods: Human B lymphoma cell line BJAB was uninfected or infected with EBV for 24 hours. Total RNA from each sample were extracted. Intact mRNA was isolated from total RNA samples and then chemically fragmented to 100-nucleoside-long fragments. m6A methylated mRNAs were immunoprecipitated with anti-N6-methyadenosine (m6A) antibody (a part of the fragmented mRNAs was kept as input). Both m6A enriched mRNAs and input mRNAs were concentrated for RNA-seq library construction. Sequencing was performed using an Illumina HiSeq 4000. Results: EBV EBNA2 and BHRF1 transcripts were m6A modified and m6A modification of BJAB transcripts changed during EBV infection. Conclusions: Our study found that some EBV transcripts were m6A modified during EBV infection and EBV infection changed m6A modification profiles of BJAB transcripts.

Establishment of Transposase-assisted Low-input m6A Sequencing Technique

Project description:As the most abundant and best-characterized internal mRNA modification, N6-methyladenosine (m6A) emerges to play a critical regulatory role in wide range of physiological and pathological processes, including gametogenesis, neuronal development, obesity and tumorigenesis. Methylated RNA immunoprecipitation coupled with next-generation sequencing (MeRIP-seq) facilitates transcriptome-wide m6A profiling, also is the most widely used technique to understand the biological significance of m6A. However, it typically requires over 100 μg of total RNA or 107 cells as input materials, hampering its application in limited samples. Here, we develop tMeRIP-seq, a transposase assisted MeRIP-seq method to achieve m6A profiling using ultra-low amount of input RNA. By marrying Tn5 tagmentation to m6A-specific immunoprecipitation, tMeRIP-seq largely improves the efficiency of library construction and reduces the input materials to as little as 60 ng total RNA or 103 cells. We apply this method on a small droplet of human blood and recapitulate the m6A profile previously reported using conventional protocol. We find tMeRIP-seq is a convenient and powerful method to examine m6A in ultra-low input material, potentially providing m6A as a new layer of bio-marker for liquid biopsy.

MeRIP-Seq of pancreatic islets in Mettl3flox/flox and islet β cell-specific Mettl3 knockout (β-Mettl3-KO) mice

Project description:Purpose: Through mRNA m6A-profiling, we aim to characterize the mRNA m6A changes in pancreatic islets obtained from Mettl3flox/flox and β-Mettl3-KO mice. Methods: Total RNA was extracted using Tripure Isolation Reagent (Roche, Mannheim, Germany) from pancreatic islets of Mettl3flox/flox and β-Mettl3-KO mice at 8 weeks old. A total of 2-3 μg RNAs were pooled from nine Mettl3flox/flox mice and twelve β-Mettl3-KO mice, respectively. Three independent biological replicates of each group were used for MeRIP-seq. Fragmented RNA (~100 nt) was incubated for 2 hr at 4oC with anti-m6A polyclonal antibody (Merk Millipore) in the immunoprecipitation experiment. Then, immunoprecipitated RNAs or Input was used for library construction with Ovation SoLo RNA-Seq System Core Kit (NuGEN). The library preparations were sequenced on an Illumina Novaseq platform with a paired-end read length of 150 bp according to the standard protocols. After mapping reads to the reference genome, exomePeak R package (version 2.16.0) was used for the m6A peak identification in each anti-m6A immunoprecipitation group with the corresponding input samples serving as a control, and q-value threshold of enrichment of 0.05 was used for all data sets. The m6A-enriched motifs of each group were identified by HOMER (version 4.9.1). Conclusion: The islet mRNA m6A profiles in Mettl3flox/flox and β-Mettl3-KO mice were characterized.

m6A-RIP-seq of Ascl1-induced neurons.

Project description:We performed m6A-RIPs in Ascl1-induced neurons (iNeurons) to investigate the neuronal m6A epitranscriptome. Immunoprecipitation was done twice using two different antibodies, acquired from Abcam and Synaptic Systems (SySy), allowing for a more robust detection of m6A modification marks. Additionally, RIP-seq was performed separately with intact and fragmented RNA. The former approach allowed to identify proportions of m6A-modified transcripts among the total number, while the latter approach provided the information to identify genomic coordinates of m6A peaks.
