Mouse Cenpb Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Cenpb Knockout Project (CRISPR/Cas9) Objective: To create a Cenpb knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Cenpb gene (NCBI Reference Sequence: NM_007682 ; Ensembl: ENSMUSG00000068267 ) is located on Mouse chromosome 2. 1 exon is identified, with the ATG start codon in exon 1 and the TGA stop codon in exon 1 (Transcript: ENSMUST00000089510). Exon 1 will be selected as target site. Cas9 and gRNA will be co-injected into fertilized eggs for KO Mouse production. The pups will be genotyped by PCR followed by sequencing analysis. Note: Mice homozygous for a knock-out allele display decreased body weight, small testis, oligospermia, and an age- and background-dependent reduction in female reproductive competence associated with abnormalities in uterus morphology, metral environment, gestational length, and parturition. Exon 1 starts from about 0.06% of the coding region. Exon 1 covers 100.0% of the coding region. The size of effective KO region: ~1795 bp. The KO region does not have any other known gene.

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.

  • Detecting Remote, Functional Conserved Domains in Entire Genomes by Combining Relaxed Sequence-Database Searches with Fold Recognition
    HMMerThread: Detecting Remote, Functional Conserved Domains in Entire Genomes by Combining Relaxed Sequence-Database Searches with Fold Recognition Charles Richard Bradshaw1¤a, Vineeth Surendranath1, Robert Henschel2,3, Matthias Stefan Mueller2, Bianca Hermine Habermann1,4*¤b 1 Bioinformatics Laboratory, Max Planck Institute of Molecular Cell Biology and Genetics, Dresden, Saxony, Germany, 2 Center for Information Services and High Performance Computing (ZIH), Technical University, Dresden, Saxony, Germany, 3 High Performance Applications, Pervasive Technology Institute, Indiana University, Bloomington, Indiana, United States of America, 4 Bioinformatics Laboratory, Scionics c/o Max Planck Institute of Molecular Cell Biology and Genetics, Dresden, Saxony, Germany Abstract Conserved domains in proteins are one of the major sources of functional information for experimental design and genome-level annotation. Though search tools for conserved domain databases such as Hidden Markov Models (HMMs) are sensitive in detecting conserved domains in proteins when they share sufficient sequence similarity, they tend to miss more divergent family members, as they lack a reliable statistical framework for the detection of low sequence similarity. We have developed a greatly improved HMMerThread algorithm that can detect remotely conserved domains in highly divergent sequences. HMMerThread combines relaxed conserved domain searches with fold recognition to eliminate false positive, sequence-based identifications. With an accuracy of 90%, our software is able to automatically predict highly divergent members of conserved domain families with an associated 3-dimensional structure. We give additional confidence to our predictions by validation across species. We have run HMMerThread searches on eight proteomes including human and present a rich resource of remotely conserved domains, which adds significantly to the functional annotation of entire proteomes.

  • Comparative Transcriptome Analysis of Obligately Asexual and Cyclically
    Hanson et al. BMC Genomics 2013, 14:412 http://www.biomedcentral.com/1471-2164/14/412 RESEARCH ARTICLE Open Access Comparative transcriptome analysis of obligately asexual and cyclically sexual rotifers reveals genes with putative functions in sexual reproduction, dormancy, and asexual egg production Sara J Hanson1, Claus-Peter Stelzer2, David B Mark Welch3 and John M Logsdon Jr1* Abstract Background: Sexual reproduction is a widely studied biological process because it is critically important to the genetics, evolution, and ecology of eukaryotes. Despite decades of study on this topic, no comprehensive explanation has been accepted that explains the evolutionary forces underlying its prevalence and persistence in nature. Monogonont rotifers offer a useful system for experimental studies relating to the evolution of sexual reproduction due to their rapid reproductive rate and close relationship to the putatively ancient asexual bdelloid rotifers. However, little is known about the molecular underpinnings of sex in any rotifer species. Results: We generated mRNA-seq libraries for obligate parthenogenetic (OP) and cyclical parthenogenetic (CP) strains of the monogonont rotifer, Brachionus calyciflorus, to identify genes specific to both modes of reproduction. Our differential expression analysis identified receptors with putative roles in signaling pathways responsible for the transition from asexual to sexual reproduction. Differential expression of a specific copy of the duplicated cell cycle regulatory gene CDC20 and specific copies of histone H2A suggest that such duplications may underlie the phenotypic plasticity required for reproductive mode switch in monogononts. We further identified differential expression of genes involved in the formation of resting eggs, a process linked exclusively to sex in this species.

ABSTRACT The development of hematopoietic lineages is based on a complex balance of transcription factors whose expression depends on the epigenetic signatures that characterize each differentiation step. The B cell lineage arises from hematopoietic stem cells through the stepwise silencing of stemness genes and balanced expression of mutually regulated transcription factors, as well as DNA rearrangement. Here we report the impact on B cell differentiation of the lack of DIDO3, a reader of chromatin status, in the mouse hematopoietic compartment.

  • Bayesian Hidden Markov Tree Models for Clustering Genes with Shared Evolutionary History
    Submitted to the Annals of Applied Statistics arXiv: arXiv:0000.0000 BAYESIAN HIDDEN MARKOV TREE MODELS FOR CLUSTERING GENES WITH SHARED EVOLUTIONARY HISTORY By Yang Liy,{,∗, Shaoyang Ningy,∗, Sarah E. Calvoz,x,{, Vamsi K. Moothak,z,x,{ and Jun S. Liuy Harvard Universityy, Broad Institutez, Harvard Medical Schoolx, Massachusetts General Hospital{, and Howard Hughes Medical Institutek Determination of functions for poorly characterized genes is cru- cial for understanding biological processes and studying human dis- eases. Functionally associated genes are often gained and lost together through evolution. Therefore identifying co-evolution of genes can predict functional gene-gene associations. We describe here the full statistical model and computational strategies underlying the orig- inal algorithm CLustering by Inferred Models of Evolution (CLIME 1.0) recently reported by us [Li et al., 2014]. CLIME 1.0 employs a mixture of tree-structured hidden Markov models for gene evolution process, and a Bayesian model-based clustering algorithm to detect gene modules with shared evolutionary histories (termed evolutionary conserved modules, or ECMs). A Dirichlet process prior was adopted for estimating the number of gene clusters and a Gibbs sampler was developed for posterior sampling. We further developed an extended version, CLIME 1.1, to incorporate the uncertainty on the evolution- ary tree structure. By simulation studies and benchmarks on real data sets, we show that CLIME 1.0 and CLIME 1.1 outperform traditional methods that use simple metrics (e.g., the Hamming distance or Pear- son correlation) to measure co-evolution between pairs of genes. 1. Introduction. The human genome encodes more than 20,000 protein- coding genes, of which a large fraction do not have annotated function to date [Galperin and Koonin, 2010].

  • PTK7) in Cancer Development and Cellular Fitness
    Characterizing the Role of Protein Tyrosine Kinase 7 (PTK7) in Cancer Development and Cellular Fitness by Sachin Anand Kumar A thesis submitted in conformity with the requirements for the degree of Master of Science Department of Molecular Genetics University of Toronto © Copyright by Sachin Anand Kumar (2015) Characterizing the Role of Protein Tyrosine Kinase 7 (PTK7) in Cancer Development and Cellular Fitness Sachin Anand Kumar Master of Science Department of Molecular Genetics University of Toronto 2015 Abstract Protein Tyrosine Kinase 7 has been recently affiliated with the development and progression of various cancers. Contradictory results about its expression, localization and processing across various cancer types has left a major gap in understanding its molecular mechanism and function. In my thesis, I utilized large data sets from essentiality screens and RNAseq, as well as antibody-related tools, to investigate the role of PTK7 in cellular fitness. I observed a negative correlation between PTK7 processing and its degree of essentiality. Furthermore, I demonstrated that the PTK7 intracellular domain (ICD) is integral to its function. Treatment of mouse xenografts with PTK7 antibodies, capable of blocking PTK7 processing, inhibited tumour growth in an ICD-expression dependent manner. Lastly, mRNA profiling of PTK7-knockdown cells and ICD over-expression cells provided a list of putative downstream gene targets under PTK7 regulation. Collectively, these findings implicate PTK7 in cellular transformation and provide insight into its signaling mechanism. II Acknowledgments First and foremost, I would like to thank my supervisor Dr. Jason Moffat. You gave me an opportunity to step outside of my comfort zone and partake in research that pushed the boundary of science, technology and discovery.

Background: Head and neck squamous cell carcinoma (HNSC) remains an important public health problem, with classic risk factors being smoking and excessive alcohol consumption and usually has a poor prognosis. Therefore, it is important to explore the underlying mechanisms of tumorigenesis and screen the genes and pathways identified from such studies and their role in pathogenesis. The purpose of this study was to identify genes or signal pathways associated with the development of HNSC. Methods: In this study, we downloaded gene expression profiles of GSE53819 from the Gene Expression Omnibus (GEO) database, including 18 HNSC tissues and 18 normal tissues.
