Project description:Purpose: The goal of this study is to investigate how METTL3 regulates islet β-cell function. 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: 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.

Our study represents the first detailed analysis of islet transcriptomes from Ythdc1flox/flox and Ythdc1-βKO mice, generated by RNA-seq technology. The RNA-seq analysis showed that 2869 genes were downregulated and 2825 genes were upregulated in the pancreatic islets of Ythdc1-βKO mice.

Project description:The goal of this study is to investigate how WTAP regulates islet β-cell function. Islets were isolated from pancreatic islets of Wtapflox/flox and Wtap-βKO mice at 7 weeks old. One islet sample was combined from three mice. Total RNA was extracted using Tripure Isolation Reagent (Roche, Mannheim, Germany). 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/mm10) with Hisat2 v2.0.5, and the aligned reads were used to quantify mRNA expression by using featureCounts v1.5.0-p3. Our study represents the first detailed analysis of islet transcriptomes from Wtapflox/flox and Wtap-βKO mice, generated by RNA-seq technology. The RNA-seq analysis showed that 3015 genes were downregulated and 2900 genes were upregulated in the pancreatic islets of Wtap-βKO mice.

Project description:Endocrine enriched genes in adult islet beta cells were identified and compared with that of induced beta cells (with M3 transcription factors) in adult. The control sample is non-beta pancreatic cells. Gene expression profile comparison of 3 samples, 3 independent repeats for each sample indicate a high degree of similarity between endogenous and induced beta cells in adult mouse.
