The effects of METTL3 on BAT development and thermogenesis

ABSTRACT: Purpose: The goal of this study is to compare transcriptome profilings of interscapular brown adipose tissue (iBAT) from BAT-specific METTL3 knockout and control mice Methods: iBATs were collected from METTL3 BKO and f/f mice at 8 weeks old, and total RNA was isolated using TriPure. RNA samples were pooled from iBATs of METTL3 BKO and f/f mice (n=4 for each group). RNA-seq was performed by using Illumina NovaSeq 6000 platform. Paired-end clean reads were aligned to the mouse reference genome (Ensemble_GRCm38.90) 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 METTL3 BKO and f/f mice, generated by RNA-seq technology. The RNA-seq analysis showed that 530 genes were down-regulated and 1552 genes were up-regulated in the iBAT of METTL3 BKO mice. GO analysis showed that the down-regulated genes were primarily related to developmental maturation, respiratory electron transport chain, adaptive thermogenesis, and energy deprivation by oxidation of organic compounds whereas the up-regulated genes were associated with muscle system process and muscle cell development.

Project description:Purpose: Through mRNA m6A-profiling, we aim to characterize the mRNA m6A changes in iBAT obtained from Mettl3flox/flox and BKO mice. Methods: Total RNA was extracted using Tripure Isolation Reagent (Roche, Mannheim, Germany) from iBAT of Mettl3 flox/flox and BKO mice at 8 weeks old. Each sample (300 μg total RNA) was pooled from 5 mice for each group. Poly(A)+ RNA was purified using Dynabeads™ mRNA Purification Kit (Invitrogen) following the manufacturer’s instructions. Chemically fragmented poly(A)+ RNA was incubated with m6A antibody (Synaptic System, 202003) for immunoprecipitation following the standard protocol of Magna MeRIPTM m6A Kit (MERK, 17-10499). Enrichment of m6A mRNA was then analyzed by high-throughput sequencing using Illumina Hiseq X platform. The m6A peaks were detected by MACS2. The motif search was detected by HOMER.

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. Each RNA sample was pooled from four Mettl3flox/flox and β-Mettl3-KO mice, respectively. Three independent biological replicates for each group were used for RNA-seq. RNA-seq was performed by deep sequencing using an Illumina Novaseq 6000 platform. Paired-end clean reads were aligned to the mouse reference genome(GRCm38.p6) with Hisat2 v2.0.5, and the aligned reads were used to quantify mRNA expression by using featureCounts v1.5.0-p3. Conclusion: Our study represents the first detailed analysis of islet transcriptomes from Mettl3flox/flox and β-Mettl3-KO mice, generated by RNA-seq technology. The RNA-seq analysis showed that 2560 genes were downregulated and 3408 genes were upregulated in the pancreatic islets of β-Mettl3-KO mice. GO analysis showed that the downregulated genes were primarily related to insulin secretion, SNARE binding, and mitochondrial respiratory chain, whereas the upregulated genes were associated with the immune response, B cell activation, and antigen binding.

Project description:Purpose: The goal of this study is to compare transcriptome profilings of liver from GBP5 knockout and WT control mice treated with GalN/LPS. Methods: GBP5 knockout and WT control mice were treated with GalN (800 μg/g body weight) and LPS (100 ng/g body weight) for 6 h to induce liver inflammation and injury. RNA samples were pooled from livers of GBP5 KO and WT mice (n=4 for each group). RNA-seq was performed by using HiSeq X Ten platform. Paired-end clean reads were aligned to the mouse reference genome (Ensembl_GRCm38.89) 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 liver transcriptomes from GBP5 KO and WT mice treated with GalN/LPS, generated by RNA-seq technology. The RNA-seq analysis showed that 405 genes were down-regulated and 33 genes were up-regulated in the liver of GBP5 KO mice. GO analysis showed that the down-regulated genes were primarily related to the immune system process and response to stress. KEGG pathway enrichment analysis showed that phagocytosis and Jak-STAT signaling pathway were significantly decreased in the liver of GBP5 KO mice.

Liver-specific overexpression of GBP5 induces liver injury and inflammation

Project description:Purpose: The goal of this study is to compare transcriptome profilings of livers in which GBP5 and βGal were overexpressed, respectively. Methods: Liver-specific GBP5-overexpressing and βGal–overexpressing mice were generated by tail-vein injection of individual purified adenovirus(6 × 1011 viral particles per mouse), respectively. RNA-seq was performed by using HiSeq X Ten platform in a single test. Paired-end clean reads were aligned to the mouse reference genome (Ensemble_GRCm38.89) 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 liver transcriptomes from GBP5- and βGal-overexpressing livers, generated by RNA-seq technology. Our results show that 633 genes were significantly up-regulated in the GBP5-overexpressing livers, whereas 586 genes were dramatically down-regulated in the GBP5-overexpressing livers. GO analysis showed that some up-regulated genes were related to the immune system process, response to stress, cell cycle, and cell death in GBP5-overexpressing livers.

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.
