M6A MeRIP-Seq of interscapular brown adipose tissue (iBAT) in Wtapflox/flox and BAT-specific Wtap knockout (BKO) mice

ABSTRACT: Purpose: Through mRNA m6A-profiling, we aim to characterize the mRNA m6A changes in iBAT obtained from Wtapflox/flox and Wtap-BKO mice. Methods: Total RNA was extracted using Tripure Isolation Reagent (Roche, Mannheim, Germany) from iBAT of Wtap flox/flox and Wtap-BKO mice at 8 weeks old. Each sample (300 μg total RNA) was pooled from 8 mice for each group. Poly(A)+ RNA was purified using Dynabeads™ mRNA Purification Kit (Invitrogen) following the manufacturer’s instructions. Fragmented mRNA was incubated with m6A antibody (Synaptic System, 202003) for immunoprecipitation. Then, immunoprecipitated mRNAs or Input was used for library construction with NEBNext ultra RNA library prepare kit for Illumina (New England Biolabs).The library preparations were sequenced on an Illumina Novaseq 6000 platform with a paired-end read length of 150 bp according to the standard protocols. The m6A peaks were detected by exomePeak R package (version 2.16.0). The motif search was detected by HOMER(version 4.9.1). Conclusion: The iBAT mRNA m6A profiles in Wtapflox/flox and BKO mice were characterized.

The effects of WTAP on BAT function

Project description:Purpose: The goal of this study is to compare transcriptome profilings of interscapular brown adipose tissue (iBAT) from BAT-specific WTAP knockout and control mice Methods: iBATs were collected from WTAP BKO and f/f mice at 8 weeks old (n=3 for each group), and total RNA was isolated using TriPure. RNA-seq was performed by using Illumina NovaSeq 6000 platform. Paired-end clean reads were aligned to the mouse reference genome (Ensemble_grcm38_p6) with TopHat (version 2.0.12), and the aligned reads were used to quantify mRNA expression by using HTSeq-count (version 0.6.1). Conclusion:Our study represents the first detailed analysis of iBAT transcriptomes from WTAP BKO and f/f mice, generated by RNA-seq technology. The RNA-seq analysis showed that 894 genes were down-regulated and 1410 genes were up-regulated in the iBAT of WTAP BKO mice. GO analysis showed that the down-regulated genes were primarily related to related to generation of precursor metabolites and energy, cellular respiration, energy derivation by oxidation of organic compounds, electron transport chain, nucleotide metabolic process and purine ribonucleotide metabolic process.

Assay for transposase-accessible chromatin-sequencing (ATAC-seq) of liver samples in Wtapflox/flox and hepatocyte-specific Wtap knockout (Wtap-HKO) mice

Project description:Purpose: The goal of this study is to determine whether hepatic deletion of Wtapaffects chromatin accessibility. Methods: Each liver sample was pooled from three Wtap-HKO and Wtapflox/flox mice, respectively. Three independent biological replicates of each group were used for ATAC-seq. Nuclei was extracted from liver samples, and the nuclei pellet was resuspended in the Tn5 transposase reaction mix. The transposition reaction was incubated at 37°C for 30 min. Equimolar Adapter1 and Adatper 2 were added after transposition, PCR was then performed to amplify the library. After the PCR reaction, libraries were purified with the AMPure beads and library quality was assessed with Qubit. The clustering of the index-coded samples was performed on a cBot Cluster Generation System using TruSeq PE Cluster Kit v3-cBot-HS (Illumina) according to the manufactuer’s instructions. After cluster generation, the library preparations were sequenced on an Illumina NovaSeq 6000 platform and 150 bp paired-end reads were generated. ATAC-seq analysis was performed using a standard protocol. Results: The hepatic chromatin accessibility in Wtapflox/flox and Wtap-HKO mice were characterized.
