Project description:N6-methyladenosine (m6A) is one of the most prevalent and abundant epigenetic modifications in various fundamental bioprocesses. We hypothesized that m6A-mediated inflammation pathway contributes to diabetes. Total RNA was extracted from the retinas of wide type rat and their littermates with diabetes by STZ injection. A total amount of 1 μg RNA per sample was used as an input for the RNA sample preparations. The clustering of the index-coded samples was performed on a cBot Cluster Generation System using TruSeq PE Cluster Kit v3-cBot-HS (Illumia), the reagents used in library preparation are NEBNext® Ultra RNA Library Prep Kit for Illumina (NEB, USA) .After cluster generation, the library preparations were sequenced on an Illumina Novaseq platform and 150 bp paired-end reads were generated. The MeRIP-seq was carried out in Novogene (Beijing, China). Briefly, 2 μg total RNA was extracted from the retinas of both wide type mice and their littermates with diabetes. The integrity and concentration of extracted RNA was detected using an Agilent 2100 bioanalyzer (Agilent) and simpliNano spectrophotometer (GE Healthcare), respectively. Fragmented RNA (~100 nt) was incubated for 2 hours at 4 ℃ with anti-m6A polyclonal antibody (Synaptic Systems) in the immunoprecipitation experiment. Then, immunoprecipitated RNA or input was used for library construction with Ovation SoLo RNA-Seq System Core Kit (NuGEN). The library preparations were sequenced on Illumina Novaseq platform with a paired-end read length of 150 bp according to the standard protocols. The sequencing was carried out with three independent biological replicates.

Project description:RNA m5C methylation profile of MCF10A and MDA486 by using MeRIP-Seq protocol

Project description:RNA m5C methylation profile of MCF10A and MDA486 by using MeRIP-Seq protocol Immunoprecipitation of Methylated mRNA at Cytosine (m5C) residues: Affinity purified of anti-methyl cytosine (m5C) polyclonal antibody 7ug (Zymo Research, Catalog#A3001-50) was conjugated with protein-A magnetic beads for 2 h at 4°C in end to end rotator. After that, conjugated beads were extensively washed with RNA immunoprecipitation (RIP) wash buffer to remove unbound antibody. Fragmented 25 ug polyA RNA (mRNA) was incubated with m5C conjugated beads for overnight at 4°C in in the rotating platform in RIP buffer. RIP was done using Megna RNA Immunoprecipitation kit (Millipore, Catalog#17-700). m5C mRNA-immune bead complex was treated with proteinase K buffer to release m5C mRNA from the conjugated antibody. To isolate m5C, mRNA was treated with phenol:chloroform:isoamyl and mixed with 400 ul of chloroform, which was centrifuged at 14000 rpm for 10 minutes to separate aqueous phase. The aqueous phase was ethanol precipitated at -80°C for overnight, to get m5C mRNA. This precipitated m5C mRNA pellet was washed twice with 70% ethanol and air dried. Finally, m5C mRNA pellet was dissolved in nuclease free Water. The m5C mRNA integrity and conentration was quantified by bioanalyzer (Agilent) and Qubit 2.0 flurometer (Invitrogen). The fragmented mRNA was used by following TruSeq RNA Sample Preparation Guide to develop RNA-Seq library for sequencing.

Project description:Many transcriptional and epigenetic networks must be integrated to maintain self-renewal and pluripotency in embryonic stem cells (ESCs) and to enable induced pluripotent stem cell (iPSC) reprogramming. Here, we explore the role of Zfp217 as a key transcriptional factor in maintaining ES cell self-renewal by performing meRIP analysis in control and Zfp217-depleted mouse stem cells. Examination of m6A levels from total RNA in control and Zfp217 shRNA infected mouse stem cells
