Mouse Mtarc2 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Mtarc2 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Mtarc2 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Mtarc2 gene (NCBI Reference Sequence: NM_133684.3 ; Ensembl: ENSMUSG00000073481 ) is located on Mouse chromosome 1. 8 exons are identified, with the ATG start codon in exon 1 and the TAG stop codon in exon 7 (Transcript: ENSMUST00000068725). Exon 3 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Mtarc2 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-221J17 as template. Cas9, gRNA and targeting vector will be co-injected into fertilized eggs for cKO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Exon 3 starts from about 44.08% of the coding region. The knockout of Exon 3 will result in frameshift of the gene. The size of intron 2 for 5'-loxP site insertion: 7225 bp, and the size of intron 3 for 3'-loxP site insertion: 1143 bp. The size of effective cKO region: ~669 bp. The cKO region does not have any other known gene.

Tandem repeats are found in the dot plot matrix. It may be difficult to construct this targeting vector. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(7169bp) | A(27.81% 1994) | C(21.34% 1530) | T(25.39% 1820) | G(25.46% 1825) Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. No significant high GC-content region is found. So this region is suitable for PCR screening or sequencing analysis.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.

In the current work, we have compared the transcriptomic and eQTL profiles of two porcine tissues (skeletal muscle and liver) which typically show highly divergent expression profiles, in 103 Duroc pigs genotyped with the Porcine SNP60 BeadChip (Illumina) and with available microarray-based measurements of hepatic and muscle mRNA levels. Since structural variation could have effects on gene expression, we have also investigated the co-localization of cis-eQTLs with copy number variant regions (CNVR) segregating in this Duroc population. Results: The analysis of differential expresssion revealed the existence of 1204 and 1490 probes that were overexpressed and underexpressed in the gluteus medius muscle when compared to liver, respectively (|fold- change| > 1.5, q-value < 0.05). By performing genome scans in 103 Duroc pigs with available expression and genotypic data, we identified 76 and 28 genome-wide significant cis-eQTLs regulating gene expression in the gluteus medius muscle and liver, respectively. Twelve of these cis-eQTLs were shared by both tissues (i.e.

    ARTICLE Received 5 Mar 2014 | Accepted 5 Aug 2014 | Published 26 Sep 2014 DOI: 10.1038/ncomms5919 OPEN Global profiling of co- and post-translationally N-myristoylated proteomes in human cells Emmanuelle Thinon1,2,*,w, Remigiusz A. Serwa1,*, Malgorzata Broncel1, James A. Brannigan3, Ute Brassat1,2,w, Megan H. Wright1,4,w, William P. Heal1,w, Anthony J. Wilkinson3, David J. Mann2,4 & Edward W. Tate1,4 Protein N-myristoylation is a ubiquitous co- and post-translational modification that has been implicated in the development and progression of a range of human diseases. Here, we report the global N-myristoylated proteome in human cells determined using quantitative chemical proteomics combined with potent and specific human N-myristoyltransferase (NMT) inhibition. Global quantification of N-myristoylation during normal growth or apoptosis allowed the identification of 4100 N-myristoylated proteins, 495% of which are identified for the first time at endogenous levels. Furthermore, quantitative dose response for inhibition of N-myristoylation is determined for 470 substrates simultaneously across the proteome. Small-molecule inhibition through a conserved substrate-binding pocket is also demonstrated by solving the crystal structures of inhibitor-bound NMT1 and NMT2. The presented data substantially expand the known repertoire of co- and post-translational N-myristoylation in addition to validating tools for the pharmacological inhibition of NMT in living cells. 1 Department of Chemistry, Imperial College London, Exhibition Road, London SW7 2AZ, UK. 2 Department of Life Sciences, Imperial College London, Exhibition Road, London SW7 2AZ, UK. 3 York Structural Biology Laboratory, Department of Chemistry, University of York, York YO10 5DD, UK.

  • Global Proteome of Lonp1+/- Mouse Embryonal Fibroblasts Reveals Impact on Respiratory Chain, but No Interdependence Between Eral1 and Mitoribosomes

Sci. 2019, 20, 4523; doi:10.3390/ijms20184523 Research Article Global proteome of LonP1+/- mouse embryonal fibroblasts reveals impact on respiratory chain, but no interdependence between Eral1 and mitoribosomes Jana Key1, Aneesha Kohli1, Clea Bárcena2, Carlos López-Otín2, Juliana Heidler3, Ilka Wittig3,*, and Georg Auburger1,* 1 Experimental Neurology, Goethe University Medical School, 60590 Frankfurt am Main; 2 Departamento de Bioquimica y Biologia Molecular, Facultad de Medicina, Instituto Universitario de Oncologia (IUOPA), Universidad de Oviedo, 33006 Oviedo, Spain; 3 Functional Proteomics Group, Goethe-University Hospital, 60590 Frankfurt am Main, Germany * Correspondence: [email protected]; [email protected] Abstract: Research on healthy ageing shows that lifespan reductions are often caused by mitochondrial dysfunction. Thus, it is very interesting that the deletion of mitochondrial matrix peptidase LonP1 was observed to abolish embryogenesis, while deletion of the mitochondrial matrix peptidase ClpP prolonged survival. To unveil the targets of each enzyme, we documented the global proteome of LonP1+/- mouse embryonal fibroblasts (MEF), for comparison with ClpP-/- depletion. Proteomic profiles of LonP1+/- MEF generated by label-free mass spectrometry were further processed with the STRING webserver Heidelberg for protein interactions. ClpP was previously reported to degrade Eral1 as a chaperone involved in mitoribosome assembly, so ClpP deficiency triggers accumulation of mitoribosomal subunits and inefficient translation. LonP1+/- MEF also showed Eral1 accumulation, but no systematic effect on mitoribosomal subunits. In contrast to ClpP-/- profiles, several components of the respiratory complex I membrane arm were accumulated, whereas the upregulation of numerous innate immune defense components was similar.

  • Analysis of Mammalian Gene Function Through Broad-Based Phenotypic
    ARTICLES Analysis of mammalian gene function through broad-based phenotypic screens across a consortium of mouse clinics The function of the majority of genes in the mouse and human genomes remains unknown. The mouse embryonic stem cell knockout resource provides a basis for the characterization of relationships between genes and phenotypes. The EUMODIC consortium developed and validated robust methodologies for the broad-based phenotyping of knockouts through a pipeline comprising 20 disease-oriented platforms. We developed new statistical methods for pipeline design and data analysis aimed at detecting reproducible phenotypes with high power. We acquired phenotype data from 449 mutant alleles, representing 320 unique genes, of which half had no previous functional annotation. We captured data from over 27,000 mice, finding that 83% of the mutant lines are phenodeviant, with 65% demonstrating pleiotropy. Surprisingly, we found significant differences in phenotype annotation according to zygosity. New phenotypes were uncovered for many genes with previously unknown function, providing a powerful basis for hypothesis generation and further investigation in diverse systems. Phenotypic annotations of knockout mutants have been generated for (EMPReSS) database10 catalogs the standard operating procedures about a third of the genes in the mouse genome1. However, the way in (SOPs) that were developed, including operational details and the which the phenotype is screened is often dependent on the expertise and parameters measured. More recently, a major single-center effort interests of the investigator, and in only a few cases has a broad-based to analyze several hundred knockout lines through a phenotyping assessment of phenotype been undertaken that encompassed the analy- pipeline has illuminated the pleiotropy that can be found and the sis of developmental, biochemical, physiological and organ systems2–4.

Ing. Ivo Provazník, Ph.D. ŠKOLITEL BRNO 2017 ABSTRACT The high-throughputs sequence technologies produce a massive amount of data, that can reveal new genes, identify splice variants, and quantify gene expression genome-wide. However, the volume and the complexity of data from RNA-seq experiments necessitate a scalable, and mathematical analysis based on a robust statistical model. Therefore, it is challenging to design integrated workflow, that incorporates the various analysis procedures. Particularly, the comparative transcriptome analysis is complicated due to several sources of measurement variability and poses numerous statistical challenges. In this research, we performed an integrated transcriptional profiling pipeline, which generates novel reproducible codes to obtain biologically interpretable results. Starting with the annotation of RNA-seq data and quality assessment, we provided a set of codes to serve the quality assessment visualization needed for establishing the RNA-Seq data analysis experiment. Additionally, we performed comprehensive differential gene expression analysis, presenting

  • Global Proteome of Lonp1+/- Mouse Embryonal
    International Journal of Molecular Sciences Article − Global Proteome of LonP1+/ Mouse Embryonal Fibroblasts Reveals Impact on Respiratory Chain, but No Interdependence between Eral1 and Mitoribosomes Jana Key 1, Aneesha Kohli 1, Clea Bárcena 2, Carlos López-Otín 2, Juliana Heidler 3, Ilka Wittig 3,* and Georg Auburger 1,* 1 Experimental Neurology, Goethe University Medical School, 60590 Frankfurt am Main, Germany; [email protected] (J.K.); [email protected] (A.K.) 2 Departamento de Bioquimica y Biologia Molecular, Facultad de Medicina, Instituto Universitario de Oncologia (IUOPA), Universidad de Oviedo, 33006 Oviedo, Spain; [email protected] (C.B.); [email protected] (C.L.-O.) 3 Functional Proteomics Group, Goethe-University Hospital, 60590 Frankfurt am Main, Germany; [email protected] * Correspondence: [email protected] (I.W.); [email protected] (G.A.) Received: 9 July 2019; Accepted: 9 September 2019; Published: 12 September 2019 Abstract: Research on healthy aging shows that lifespan reductions are often caused by mitochondrial dysfunction. Thus, it is very interesting that the deletion of mitochondrial matrix peptidase LonP1 was observed to abolish embryogenesis, while deletion of the mitochondrial matrix peptidase Caseinolytic Mitochondrial Matrix Peptidase Proteolytic Subunit (ClpP) prolonged survival. To unveil the targets +/ of each enzyme, we documented the global proteome of LonP1 − mouse embryonal fibroblasts / +/ (MEF), for comparison with ClpP− − depletion. Proteomic profiles of LonP1 − MEF generated by label-free mass spectrometry were further processed with the STRING (Search tool for the retrieval of interacting genes) webserver Heidelberg for protein interactions. ClpP was previously reported to degrade Eral1 as a chaperone involved in mitoribosome assembly, so ClpP deficiency triggers the +/ accumulation of mitoribosomal subunits and inefficient translation.
