Zc3h10 is a novel mitochondrial regulator

ABSTRACT: Mitochondria are the energy-generating hubs of the cell. In spite of considerable advances, our understanding of the factors that regulate the molecular circuits that govern mitochondrial function remains incomplete. Using a genome-wide functional screen, we have identified the poorly characterized protein Zinc finger CCCH-type containing 10 (Zc3h10) as regulator of mitochondrial physiology. We show that Zc3h10 is upregulated during physiological mitochondriogenesis such as myoblasts differentiation into myotubes. Zc3h10 overexpression boosts mitochondrial function and promotes myoblasts differentiation. On the other hand, depletion of Zc3h10 results in impaired myoblasts differentiation, mitochondrial dysfunction, reduced expression of electron transport chain (ETC) subunits and blunted TCA cycle flux. Notably, we have identified a loss-of-function mutation of Zc3h10 in humans (Tyr105 to Cys105) that is associated with increased body mass index, fat mass, fasting glucose and triglycerides. Isolated peripheral blood mononuclear cells from Cys105 homozygotes display reduced oxygen consumption rate, some ETC subunit expression and decreased levels of some TCA cycle metabolites that derive in mitochondrial dysfunction. Finally, our study identifies Zc3h10 as a novel mitochondrial regulator.

Dissection of the cellular function of the ZBED6 transcription factor in mouse myoblast cells, ZBED6-KO Medium

Project description:The transcription factor ZBED6 acts as a repressor of Igf2 and affects directly or indirectly the transcriptional regulation of thousands of genes. Here, we use gene editing in mouse C2C12 myoblasts and show that ZBED6 regulates Igf2 exclusively through its binding site 5′-GGCTCG-3′ in intron 1 of Igf2. Deletion of this motif (Igf2ΔGGCT) or complete ablation of Zbed6 leads to ~20-fold up-regulation of IGF2 protein. Quantitative proteomics revealed an activation of Ras signaling pathway in both Zbed6-/- and Igf2ΔGGCT myoblasts, and a significant enrichment of mitochondrial membrane proteins among proteins showing altered expression in Zbed6-/- myoblasts. Both Zbed6-/- and Igf2ΔGGCT myoblasts showed a faster growth rate and developed myotube hypertrophy. These cells exhibited an increased O2 consumption rate, due to IGF2 up-regulation. Transcriptome analysis revealed ~30% overlap between differentially expressed genes in Zbed6-/- and Igf2ΔGGCT myotubes, with an enrichment of up-regulated genes involved in muscle development. In contrast, ZBED6-overexpression in myoblasts led to cell apoptosis, cell cycle arrest, reduced mitochondrial activities and ceased myoblast differentiation. The similarities in growth and differentiation phenotypes observed in Zbed6-/- and Igf2ΔGGCT myoblasts demonstrates that ZBED6 affects mitochondrial activity and myogenesis largely through its regulation of IGF2 expression. This study suggests that the interaction between ZBED6-Igf2 may be a therapeutic target for human diseases where anabolism is impaired.

E. coli BW25113 proteomics in nutrient-rich and minimal medium

Project description:E. coli BW25113 growth in a nutrient-rich medium supplemented with 20 proteinogenic amino acid medium was studied and compared to growth in minimal medium. Proteome data from these experiments revealed significant differences in amino acid synthesis and transport proteins that were reduced in the nutrient-rich meidum. Changes in energy production and conversion proteins were also observed as in nutrient-rich conditions pyruvate dehydrogenase complex and acetate producing proteins increased, while the TCA cycle proteins decreased.

Dynamic profiling of the protein life cycle in response to pathogens (protein)

Project description:Protein expression is regulated by production and degradation of mRNAs and proteins, but their specific relationships remain unknown. We combine measurements of protein production and degradation and mRNA dynamics to build a quantitative genomic model of the differential regulation of gene expression in LPS stimulated mouse dendritic cells. Changes in mRNA abundance play a dominant role in determining most dynamic fold changes in protein levels. Conversely, the preexisting proteome of proteins performing basic cellular functions is remodeled primarily through changes in protein production or degradation, accounting for over half of the absolute change in protein molecules in the cell. Thus, the proteome is regulated by transcriptional induction of novel cellular functions and remodeling of preexisting functions through the protein life cycle. Mouse primary dendritic cells were treated with LPS or mock stimulus and profiled over a 12-hour time course. Cells were grown in M-labeled SILAC media, which was replaced with H-labeled SILAC media at time 0. Aliquots were taken at 0, 0.5, 1, 2, 3, 4, 5, 6, 9, and 12 hours post-stimulation and added to equal volumes of a master mix of unlabeled (L) cells for the purpose of normalization. RNA-Seq was performed at 0, 1, 2, 4, 6, 9, and 12 hours post-stimulation.

Proteomic cellular signatures of kinase inhibitor-induced cardiotoxicity

Project description:Drug Toxicity Signature Generation Center (DToxS) at the Icahn School of Medicine at Mount Sinai is an integral part of the NIH Library of Integrated Network-Based Cellular Signatures (LINCS) program. A key aim of DToxS is to generate both proteomic and transcriptomic signatures that cab predict adverse effects, especially cardiotoxicity, of drugs approved by the Food and Drug Administration. Towards this goal, high throughput shot-gun proteomics experiments on 308 cell line/drug combinations (from four primary human cardiomyocyte cell lines purchased from PromoCell), 64 HeLa control lysates, and 9 auxiliary treatment samples have been conducted at the Center for Advanced Proteomics Research at Rutgers-New Jersey Medical School. The integrated proteomic and transcriptomic signatures have been used for computational network analysis to identify cellular signatures of cardiotoxicity that may predict drug-induced toxicity and possible mitigation of such toxicities by mixing different drugs. Both raw and processed proteomics data have been carefully controlled for quality and have been made publicly available via the PRoteomics IDEntifications (PRIDE) database. As such, this broad drug-stimulated proteomic dataset is valuable for the prediction drug toxicities and their mitigation. All data are available through CC BY 4.0 open license.
