G3BP1 translocates into mitochondria to impair MCU complex function and promotes NASH progression [G3bp1-HKO and G3bp1-Flox mice with BSA or PA treatment]

Project description:Mitochondrial calcium signaling plays a critical role in mitochondrial homeostasis during non-alcoholic steatohepatitis (NASH) progression. Here, we report Ras‐GTPase activating protein SH3 domain‐binding protein 1 (G3BP1), a core protein of stress granule (SG), significantly upregulated in NAFLD/NASH patients, mouse models and palmitic acid-stimulated hepatocytes. Hepatocyte-specific G3BP1 deficiency attenuates NASH in two dietary mouse models. SG and the mitochondrial import protein TOM70 collaboratively mediate the translocation of G3BP1 to the mitochondria. G3BP1 interacts and stabilizes mitochondrial calcium uptake 1 (MICU1) via inhibiting YME1L1-mediated degradation of MICU1, and also impedes MCU complex activity and assembly, leading to mitochondrial calcium overload. Moreover, metabolic stress suppresses TRIM25-mediated K63-ubiquitination of G3BP1 and subsequent SG disassembly. Pharmacological inhibition of G3BP1 impairs the G3BP1-MICU1 interaction and prevents mitochondrial homeostasis imbalance and NASH progression. Collectively, we uncover the significant role of mitochondrial G3BP1 in mitochondrial homeostasis and NASH progression, which provides a potential target for therapeutic interventions.

RNA-seq analysis of mRNA profiles in the livers of Mettl3 flox/flox and hepatocyte-specific Mettl3 knockout (HKO) mice

Project description:Purpose: The goal of this study is to compare transcriptome profilings of liver from Mettl3 flox/flox and hepatocyte-specific Mettl3 knockout (HKO) mice. Methods: Total RNA was extracted using Tripure Isolation Reagent (Roche, Mannheim, Germany) from livers of Mettl3 flox/flox and HKO mice at 8 weeks old. mRNA profiles were generated by deep sequencing using an Illumina HiSeq X Ten platform. Paired-end clean reads were aligned to the mouse reference genome(Ensemble_GRCm38.90) with Hisat2 (version 2.0.4), and the aligned reads were used to quantify mRNA expression by using HTSeq (version 0.9.1). Conclusion: The hepatic mRNA profiles in Mettl3 flox/flox and HKO mice were characterized.

mRNA Expression Changes Induced by Myocardial MCU Inhibition

Project description:Mitochondrial calcium is an important second-messenger controlling fight-or-flight responses in the heart. The molecular identity of MCU (Mitochondrial Calcium Uniporter) was recently discovered allowing us to test this hypothesis in vivo by expressing a myocardial delimited dominant negative form of MCU. We queried mRNA expression changes induced by dominant negative MCU expression in the heart. Neonatal (< 24 h) and 6 week old hearts were harvested from mice expressing the dominant negative MCU construct or wild-type littermates.

ATAC-seq of liver samples in Mettl3 flox/flox and hepatocyte-specific Mettl3 knockout (HKO) mice

Project description:Purpose: The goal of this study is to determine whether hepatic deletion of Mettl3 affects chromatin accessibility. Methods: Liver samples were pooled from livers of Mettl3 HKO and Mettl3 flox/flox mice (n=4 for each group). 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 Mettl3 flox/flox and HKO mice were characterized.

m6A MeRIP-Seq of liver in Mettl3flox/flox and hepatocyte-specific Mettl3 knockout (HKO) mice

Project description:Purpose: Through mRNA m6A-profiling, we aim to characterize the mRNA m6A changes in the liver obtained from Mettl3flox/flox and HKO mice. Methods: Total RNA was extracted using Tripure Isolation Reagent (Roche, Mannheim, Germany) from liver of Mettl3 flox/flox and HKO mice at 8 weeks old. Each sample (300 μg total RNA) was pooled from 3 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 (MERCK, 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 MEME and DREME. Conclusion: The mRNA m6A profiles in the liver of Mettl3flox/flox and HKO mice were characterized.

Gene expression microarray analysis on the dentate gyrus of alpha-CaMKII HKO mice

Project description:We previously found that mice with heterozygous knockout of the alpha-isoform of calcium/calmodulin-dependent protein kinase II (alpha-CaMKII HKO mice) show various dysregulated behaviors, including cyclic variations in locomotor activity (LA), suggesting that alpha-CaMKII HKO mice may serve as an animal model showing infradian oscillation of mood. We performed gene expression microarray analysis of dentate gyrus from alpha-CaMKII HKO mice. Mice were selected for the sampling such that their LA levels varied among the mice. Dentate gyrus RNA isolated from alpha-CaMKII HKO mice.
