Mouse Ccni Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Ccni Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Ccni conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Ccni gene (NCBI Reference Sequence: NM_017367 ; Ensembl: ENSMUSG00000063015 ) is located on Mouse chromosome 5. 7 exons are identified, with the ATG start codon in exon 2 and the TAG stop codon in exon 7 (Transcript: ENSMUST00000058550). Exon 2 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Ccni gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP24-141M16 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: Mice homozygous for a targeted null mutation are viable and fertile and do not display any gross physical or behavioral abnormalities. Exon 2 starts from about 100% of the coding region. The knockout of Exon 2 will result in frameshift of the gene. The size of intron 1 for 5'-loxP site insertion: 3451 bp, and the size of intron 2 for 3'-loxP site insertion: 12612 bp. The size of effective cKO region: ~614 bp. The cKO region does not have any other known gene.

  • Multi-Targeted Mechanisms Underlying the Endothelial Protective Effects of the Diabetic-Safe Sweetener Erythritol
    Multi-Targeted Mechanisms Underlying the Endothelial Protective Effects of the Diabetic-Safe Sweetener Erythritol Danie¨lle M. P. H. J. Boesten1*., Alvin Berger2.¤, Peter de Cock3, Hua Dong4, Bruce D. Hammock4, Gertjan J. M. den Hartog1, Aalt Bast1 1 Department of Toxicology, Maastricht University, Maastricht, The Netherlands, 2 Global Food Research, Cargill, Wayzata, Minnesota, United States of America, 3 Cargill RandD Center Europe, Vilvoorde, Belgium, 4 Department of Entomology and UCD Comprehensive Cancer Center, University of California Davis, Davis, California, United States of America Abstract Diabetes is characterized by hyperglycemia and development of vascular pathology. Endothelial cell dysfunction is a starting point for pathogenesis of vascular complications in diabetes. We previously showed the polyol erythritol to be a hydroxyl radical scavenger preventing endothelial cell dysfunction onset in diabetic rats. To unravel mechanisms, other than scavenging of radicals, by which erythritol mediates this protective effect, we evaluated effects of erythritol in endothelial cells exposed to normal (7 mM) and high glucose (30 mM) or diabetic stressors (e.g. SIN-1) using targeted and transcriptomic approaches. This study demonstrates that erythritol (i.e. under non-diabetic conditions) has minimal effects on endothelial cells. However, under hyperglycemic conditions erythritol protected endothelial cells against cell death induced by diabetic stressors (i.e. high glucose and peroxynitrite). Also a number of harmful effects caused by high glucose, e.g. increased nitric oxide release, are reversed. Additionally, total transcriptome analysis indicated that biological processes which are differentially regulated due to high glucose are corrected by erythritol. We conclude that erythritol protects endothelial cells during high glucose conditions via effects on multiple targets.

  • Supplemental Information
    Supplemental information Dissection of the genomic structure of the miR-183/96/182 gene. Previously, we showed that the miR-183/96/182 cluster is an intergenic miRNA cluster, located in a ~60-kb interval between the genes encoding nuclear respiratory factor-1 (Nrf1) and ubiquitin-conjugating enzyme E2H (Ube2h) on mouse chr6qA3.3 (1). To start to uncover the genomic structure of the miR- 183/96/182 gene, we first studied genomic features around miR-183/96/182 in the UCSC genome browser (http://genome.UCSC.edu/), and identified two CpG islands 3.4-6.5 kb 5’ of pre-miR-183, the most 5’ miRNA of the cluster (Fig. 1A; Fig. S1 and Seq. S1). A cDNA clone, AK044220, located at 3.2-4.6 kb 5’ to pre-miR-183, encompasses the second CpG island (Fig. 1A; Fig. S1). We hypothesized that this cDNA clone was derived from 5’ exon(s) of the primary transcript of the miR-183/96/182 gene, as CpG islands are often associated with promoters (2). Supporting this hypothesis, multiple expressed sequences detected by gene-trap clones, including clone D016D06 (3, 4), were co-localized with the cDNA clone AK044220 (Fig. 1A; Fig. S1). Clone D016D06, deposited by the German GeneTrap Consortium (GGTC) (http://tikus.gsf.de) (3, 4), was derived from insertion of a retroviral construct, rFlpROSAβgeo in 129S2 ES cells (Fig. 1A and C). The rFlpROSAβgeo construct carries a promoterless reporter gene, the β−geo cassette - an in-frame fusion of the β-galactosidase and neomycin resistance (Neor) gene (5), with a splicing acceptor (SA) immediately upstream, and a polyA signal downstream of the β−geo cassette (Fig.

  • Recount Brain Example with Data from SRP027383
    recount_brain example with data from SRP027383 true Abstract This is an example on how to use recount_brain applied to the SRP027383 study. We show how to download data from recount2, add the sample metadata from recount_brain, explore the sample metadata and the gene expression data, and perform a gene expression analysis. Introduction This document is an example of how you can use recount_brain. We will use the data from the SRA study SRP027383 which is described in “RNA-seq of 272 gliomas revealed a novel, recurrent PTPRZ1-MET fusion transcript in secondary glioblastomas” (Bao, Chen, Yang, Zhang, et al., 2014). As you can see in Figure @ref(fig:runselector) a lot of the metadata for these samples is missing from the SRA Run Selector which makes it a great case for using recount_brain. We will show how to add the recount_brain metadata and perform a gene differential expression analysis using this information. Sample metadata Just like any study in recount2 (Collado-Torres, Nellore, Kammers, Ellis, et al., 2017), we first need to download the gene count data using recount::download_study(). Since we will be using many functions from the recount package, lets load it first1. ## Load the package library('recount') Download gene data Having loaded the package, we next download the gene-level data. if(!file.exists(file.path('SRP027383', 'rse_gene.Rdata'))) { download_study('SRP027383') } load(file.path('SRP027383', 'rse_gene.Rdata'), verbose = TRUE) ## Loading objects: ## rse_gene 1If you are a first time recount user, we recommend first reading the package vignette at bioconductor.org/packages/recount. 1 Figure 1: SRA Run Selector information for study SRP027383.

However, linking common variants to genes that are causal for CKD etiology remains challenging. By adapting self-transcribing active regulatory region sequencing, we evaluated the effect of genetic variation on DNA regulatory elements (DREs). Variants in linkage with the CKD-associated single-nucleotide polymorphism rs11959928 were shown to affect DRE function, illustrating that genes regulated by DREs colocalizing with CKD-associated variation can be dysregulated and therefore, considered as CKD candidate genes. To identify target genes of these DREs, we used circular chro- mosome conformation capture (4C) sequencing on glomerular endothelial cells and renal tubular epithelial cells. Our 4C analyses revealed interactions of CKD-associated susceptibility regions with the transcriptional start sites of 304 target genes. Overlap with multiple databases confirmed that many of these target genes are involved in kidney homeostasis.

Phase-dependent expression and cell-cycle checkpoints require a high level of control. A large number of genes with varying functions and modes of action are responsible for this biology. In a targeted exploration of the FANTOM2–Variable Protein Set, a number of mouse homologs to known cell-cycle regulators as well as novel members of cell-cycle families were identified. Focusing on two prototype cell-cycle families, the cyclins and the NIMA-related kinases (NEKs), we believe we have identified all of the mouse members of these families, 24 cyclins and 10 NEKs, and mapped them to ENSEMBL transcripts. To attempt to globally identify all potential cell cycle-related genes within mouse, the MGI (Mouse Genome Database) assignments for the RIKEN Representative Set (RPS) and the results from two homology-based queries were merged.

However, only few are known to be located in coding sequences and modify the amino acid sequence of the protein product. Here, we used high-throughput data, variant prediction tools, and protein structural information in order to find structural and functional preferences for coding RNA editing. We show that RNA editing has a unique pattern of amino acid changes characterized by enriched stop-to-tryptophan changes, positive-to-neutral and neutral-to-positive charge changes. RNA editing tends to have stronger structural effect than equivalent A-to-G SNPs but weaker effect than random A-to-G mutagenesis events. Sites edited at low level tend to be located at conserved positions with stronger predicted delete- rious effect on proteins comparing to sites edited at high frequencies. Lowly edited sites tend to destabilize the protein structure and affect amino acids with larger number of intra-molecular contacts. Still, some highly edited sites are predicted also to prominently affect structure and tend to be located at critical positions of the protein matrix and are likely to be functionally important.

Data preprocessing. The expression data consisted of the values of the signal, detection call, and detection p-value computed for the probe sets by the Affymetrix Gene Suite v.5 program (See Appendices C to E, 1). The signal intensity value of a probe set reflects the abundance of the gene in the sample. Hence if the detection call designates a probe set as absent, the actual value of signal is not meaningful. For this reason, the signal value of a probe set was truncated from below by setting it to zero if the corresponding detection call was absent. 2. Expression modeling and gene selection. Three pairs of arrays at each time point were created to mimic the experimental to control ratio (Cy5 to Cy3) using zinc- ' induced NIH3T3 cells lacking Arf as control.

  • Genetic Interactions Between Specific Chromosome Copy Number Alterations Dictate Complex Aneuploidy Patterns
    Downloaded from genesdev.cshlp.org on October 1, 2021 - Published by Cold Spring Harbor Laboratory Press Genetic interactions between specific chromosome copy number alterations dictate complex aneuploidy patterns Madhwesh C. Ravichandran, Sarah Fink, Matthew N. Clarke, Franziska Christina Hofer, and Christopher S. Campbell Department of Chromosome Biology, Max F. Perutz Laboratories, University of Vienna, Vienna Biocenter, Vienna 1030, Austria Cells that contain an abnormal number of chromosomes are called aneuploid. High rates of aneuploidy in cancer are correlated with an increased frequency of chromosome missegregation, termed chromosomal instability (CIN). Both high levels of aneuploidy and CIN are associated with cancers that are resistant to treatment. Although aneuploidy and CIN are typically detrimental to cell growth, they can aid in adaptation to selective pressures. Here, we induced extremely high rates of chromosome missegregation in yeast to determine how cells adapt to CIN over time. We found that adaptation to CIN occurs initially through many different individual chromosomal aneuploidies. In- terestingly, the adapted yeast strains acquire complex karyotypes with specific subsets of the beneficial aneuploid chromosomes. These complex aneuploidy patterns are governed by synthetic genetic interactions between indi- vidual chromosomal abnormalities, which we refer to as chromosome copy number interactions (CCNIs). Given enough time, distinct karyotypic patterns in separate yeast populations converge on a refined complex aneuploid state. Surprisingly, some chromosomal aneuploidies that provided an advantage early on in adaptation are eventu- ally lost due to negative CCNIs with even more beneficial aneuploid chromosome combinations. Together, our results show how cells adapt by obtaining specific complex aneuploid karyotypes in the presence of CIN.
