The effects of WTAP on BAT function

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. RNA samples were isolated from iBATs of WTAP BKO and f/f mice at 8 weeks old (n=3 for each group). mRNA profiles of WTAP BKO and f/f iBATs were generated by deep sequencing using Illumina NovaSeq 6000 platform.
