Mouse Dctn3 Conditional Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Dctn3 Conditional Knockout Project (CRISPR/Cas9) Objective: To create a Dctn3 conditional knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Dctn3 gene (NCBI Reference Sequence: NM_016890 ; Ensembl: ENSMUSG00000028447 ) is located on Mouse chromosome 4. 7 exons are identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 7 (Transcript: ENSMUST00000030158). Exon 4~5 will be selected as conditional knockout region (cKO region). Deletion of this region should result in the loss of function of the Mouse Dctn3 gene. To engineer the targeting vector, homologous arms and cKO region will be generated by PCR using BAC clone RP23-32N21 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 4 starts from about 48.21% of the coding region. The knockout of Exon 4~5 will result in frameshift of the gene. The size of intron 3 for 5'-loxP site insertion: 2396 bp, and the size of intron 5 for 3'-loxP site insertion: 940 bp. The size of effective cKO region: ~1545 bp. The cKO region does not have any other known gene.

No significant tandem repeat is found in the dot plot matrix. So this region is suitable for PCR screening or sequencing analysis. Overview of the GC Content Distribution Window size: 300 bp Sequence 12 Summary: Full Length(8045bp) | A(22.16% 1783) | C(26.55% 2136) | T(25.61% 2060) | G(25.68% 2066) Note: The sequence of homologous arms and cKO region is analyzed to determine the GC content. Significant high GC-content regions are found. It may be difficult to construct this targeting vector.

Integral to this tool are the \seq2gene" and \gene2pathway" components in series that infer a quantitative pathway-level profile for each sample. The seq2gene function assigns phenotype-associated significance of genomic regions to gene-level scores, where the significance could be p-values of SNPs or point mutations, protein-binding affinity, or transcriptional expression level. The seq2gene function has the feasibility to assign non-exon regions to a range of neighboring genes besides the nearest one, thus facilitating the study of functional non-coding elements[2]. Then the gene2pathway summarizes gene-level measurements to pathway-level scores, comparing the quantity of significance for gene members within a pathway with those outside a pathway.

  • Profilin 1 Associates with Stress Granules and ALS-Linked Mutations Alter Stress Granule Dynamics
    The Journal of Neuroscience, June 11, 2014 • 34(24):8083–8097 • 8083 Neurobiology of Disease Profilin 1 Associates with Stress Granules and ALS-Linked Mutations Alter Stress Granule Dynamics Matthew D. Figley,1,2 Gregor Bieri,1,2 Regina-Maria Kolaitis,3 J. Paul Taylor,3 and Aaron D. Gitler1 1Department of Genetics and 2Neuroscience Graduate Program, Stanford University School of Medicine, Stanford, California 94305, and 3Department of Cell and Molecular Biology, St Jude Children’s Research Hospital, Memphis, Tennessee 38105 Mutations in the PFN1 gene encoding profilin 1 are a rare cause of familial amyotrophic lateral sclerosis (ALS). Profilin 1 is a well studied actin-binding protein but how PFN1 mutations cause ALS is unknown. The budding yeast, Saccharomyces cerevisiae, has one PFN1 ortholog. We expressed the ALS-linked profilin 1 mutant proteins in yeast, demonstrating a loss of protein stability and failure to restore growth to profilin mutant cells, without exhibiting gain-of-function toxicity. This model provides for simple and rapid screening of novel ALS-linked PFN1 variants. To gain insight into potential novel roles for profilin 1, we performed an unbiased, genome-wide synthetic lethal screen with yeast cells lacking profilin (pfy1⌬). Unexpectedly, deletion of several stress granule and processing body genes, including pbp1⌬, were found to be synthetic lethal with pfy1⌬. Mutations in ATXN2, the human ortholog of PBP1, are a known ALS genetic risk factor and ataxin 2 is a stress granule component in mammalian cells. Given this genetic interaction and recent evidence linking stress granule dynamics to ALS pathogenesis, we hypothesized that profilin 1 might also associate with stress granules.

  • Detection of Novel Amplicons in Prostate Cancer by Comprehensive
    Detection of Novel Amplicons in Prostate Cancer by Comprehensive Genomic Profiling of Prostate Cancer Cell Lines Using Oligonucleotide-Based ArrayCGH Joern Kamradt1.*, Volker Jung1., Kerstin Wahrheit1, Laura Tolosi2, Joerg Rahnenfuehrer3, Martin Schilling4, Robert Walker5, Sean Davis5, Michael Stoeckle1, Paul Meltzer5, Bernd Wullich1 1 Department of Urology and Pediatric Urology, University of Saarland, Homburg/Saar, Germany, 2 Department of Computational Biology and Applied Algorithmics, Max-Planck Institute for Informatics, Saarbru¨cken, Germany, 3 Statistische Methoden in der Genetik und Chemometrie Fachbereich Statistik, Universita¨t Dortmund, Dortmund, Germany, 4 Department of General, Visceral, Vascular and Pediatric Surgery, University of the Saarland, Homburg/Saar, Germany, 5 Genetics Branch, National Cancer Institute, National Institutes of Health, Bethesda, Maryland, United States of America Background. The purpose of this study was to prove the feasibility of a longmer oligonucleotide microarray platform to profile gene copy number alterations in prostate cancer cell lines and to quickly indicate novel candidate genes, which may play a role in carcinogenesis. Methods/Results and Findings. Genome-wide screening for regions of genetic gains and losses on nine prostate cancer cell lines (PC3, DU145, LNCaP, CWR22, and derived sublines) was carried out using comparative genomic hybridization on a 35,000 feature oligonucleotide microarray (arrayCGH). Compared to conventional chromosomal CGH, more deletions and small regions of gains, particularly in pericentromeric regions and regions next to the telomeres, were detected. As validation of the high-resolution of arrayCGH we further analyzed a small amplicon of 1.7 MB at 9p13.3, which was found in CWR22 and CWR22-Rv1. Increased copy number was confirmed by fluorescence in situ hybridization using the BAC clone RP11- 165H19 from the amplified region comprising the two genes interleukin 11 receptor alpha (IL11-RA) and dynactin 3 (DCTN3).

Coexpression Networks Based on Natural Variation in Human Gene Expression at Baseline and Under Stress Abstract Genes interact in networks to orchestrate cellular processes. Here, we used coexpression networks based on natural variation in gene expression to study the functions and interactions of human genes. We asked how these networks change in response to stress. First, we studied human coexpression networks at baseline. We constructed networks by identifying correlations in expression levels of 8.9 million gene pairs in immortalized B cells from 295 individuals comprising three independent samples. The resulting networks allowed us to infer interactions between biological processes. We used the network to predict the functions of poorly-characterized human genes, and provided some experimental support. Examining genes implicated in disease, we found that IFIH1, a diabetes susceptibility gene, interacts with YES1, which affects glucose transport. Genes predisposing to the same diseases are clustered non-randomly in the network, suggesting that the network may be used to identify candidate genes that influence disease susceptibility.
