Mouse Snapc4 Knockout Project (CRISPR/Cas9) https://www.alphaknockout.com Mouse Snapc4 Knockout Project (CRISPR/Cas9) Objective: To create a Snapc4 knockout Mouse model (C57BL/6J) by CRISPR/Cas-mediated genome engineering. Strategy summary: The Snapc4 gene (NCBI Reference Sequence: NM_172339 ; Ensembl: ENSMUSG00000036281 ) is located on Mouse chromosome 2. 23 exons are identified, with the ATG start codon in exon 2 and the TAG stop codon in exon 22 (Transcript: ENSMUST00000035427). Exon 2~16 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: Exon 2 starts from the coding region. Exon 2~16 covers 49.66% of the coding region. The size of effective KO region: ~9498 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.

  • Transcriptional Control of Tissue-Resident Memory T Cell Generation
    Transcriptional control of tissue-resident memory T cell generation Filip Cvetkovski Submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy in the Graduate School of Arts and Sciences COLUMBIA UNIVERSITY 2019 © 2019 Filip Cvetkovski All rights reserved ABSTRACT Transcriptional control of tissue-resident memory T cell generation Filip Cvetkovski Tissue-resident memory T cells (TRM) are a non-circulating subset of memory that are maintained at sites of pathogen entry and mediate optimal protection against reinfection. Lung TRM can be generated in response to respiratory infection or vaccination, however, the molecular pathways involved in CD4+TRM establishment have not been defined. Here, we performed transcriptional profiling of influenza-specific lung CD4+TRM following influenza infection to identify pathways implicated in CD4+TRM generation and homeostasis. Lung CD4+TRM displayed a unique transcriptional profile distinct from spleen memory, including up-regulation of a gene network induced by the transcription factor IRF4, a known regulator of effector T cell differentiation. In addition, the gene expression profile of lung CD4+TRM was enriched in gene sets previously described in tissue-resident regulatory T cells. Up-regulation of immunomodulatory molecules such as CTLA-4, PD-1, and ICOS, suggested a potential regulatory role for CD4+TRM in tissues. Using loss-of-function genetic experiments in mice, we demonstrate that IRF4 is required for the generation of lung-localized pathogen-specific effector CD4+T cells during acute influenza infection. Influenza-specific IRF4−/− T cells failed to fully express CD44, and maintained high levels of CD62L compared to wild type, suggesting a defect in complete differentiation into lung-tropic effector T cells.

More than 160 loci have been associated with IBD, but the functional implication of many of the associated genes remains unclear. N6-Methyladenosine (m6A) is the most abundant internal modification in mRNA. m6A methylation regulates many aspects of mRNA metabolism, playing important roles in the development of several pathologies. Interestingly, SNPs located near or within m6A motifs have been proposed as possible contributors to disease pathogenesis.

  • Genomic Study of RNA Polymerase II and III Snapc-Bound Promoters Reveals a Gene Transcribed by Both Enzymes and a Broad Use of Common Activators
    Genomic Study of RNA Polymerase II and III SNAPc-Bound Promoters Reveals a Gene Transcribed by Both Enzymes and a Broad Use of Common Activators Nicole James Faresse1., Donatella Canella1., Viviane Praz1,2, Joe¨lle Michaud1¤, David Romascano1, Nouria Hernandez1* 1 Center for Integrative Genomics, Faculty of Biology and Medicine, University of Lausanne, Lausanne, Switzerland, 2 Swiss Institute of Bioinformatics, Lausanne, Switzerland Abstract SNAPc is one of a few basal transcription factors used by both RNA polymerase (pol) II and pol III. To define the set of active SNAPc-dependent promoters in human cells, we have localized genome-wide four SNAPc subunits, GTF2B (TFIIB), BRF2, pol II, and pol III. Among some seventy loci occupied by SNAPc and other factors, including pol II snRNA genes, pol III genes with type 3 promoters, and a few un-annotated loci, most are primarily occupied by either pol II and GTF2B, or pol III and BRF2. A notable exception is the RPPH1 gene, which is occupied by significant amounts of both polymerases. We show that the large majority of SNAPc-dependent promoters recruit POU2F1 and/or ZNF143 on their enhancer region, and a subset also recruits GABP, a factor newly implicated in SNAPc-dependent transcription. These activators associate with pol II and III promoters in G1 slightly before the polymerase, and ZNF143 is required for efficient transcription initiation complex assembly. The results characterize a set of genes with unique properties and establish that polymerase specificity is not absolute in vivo.

China; 3Livestock Improvement Corporation, Newstead, Hamilton 3240, New Zealand; 4Genomics Platform, GIGA, University of Liège (B34), 4000-Liège, Belgium We herein report the result of a large-scale, next generation sequencing (NGS)-based screen for embryonic lethal (EL) mu- tations in Belgian beef and New Zealand dairy cattle. We estimated by simulation that cattle might carry, on average, ∼0.5 recessive EL mutations. We mined exome sequence data from >600 animals, and identified 1377 stop-gain, 3139 frame-shift, 1341 splice-site, 22,939 disruptive missense, 62,399 benign missense, and 92,163 synonymous variants. We show that cattle have a comparable load of loss-of-function (LoF) variants (defined as stop-gain, frame-shift, or splice-site variants) as humans despite having a more variable exome. We genotyped >40,000 animals for up to 296 LoF and 3483 disruptive missense, breed-specific variants.

Analysis of the large amount of data generated by NGS is computationally intensive and require new computational methods. One of the current problems in genomic data analysis is the lack of computational methods for functional annotation of DNA sequence variants (DSVs), especially regulatory DNA sequence variants (rDSVs). In recent years, rDSVs have been shown to be the primary cause of complex diseases, supported by the fact that functional regulatory sites are more polymorphic than coding regions, and that rDSVs vastly outnumber coding variants. Also, GWAS studies of complex traits have shown that SNPs with the strongest association signals lie outside known genes in non-coding regions of the genome.

  • Methods for Determining the Genetic Causes of Rare Diseases

However, the power to discover the genetic causes of many unexplained rare diseases is hindered by a paucity of cases with a shared molecular aetiology. This thesis presents research into statistical and computational methods for determining the genetic causes of rare diseases. Methods described herein treat important aspects of the nature of rare diseases, including genetic and phenotypic heterogeneity, phenotypes involving multiple organ systems, Mendelian modes of inheritance and the incorporation of complex prior information such as model organism phenotypes and evolutionary conservation. The complex nature of rare disease phenotypes and the need to aggregate patient data across many centres has led to the adoption of the Human Phenotype Ontology (HPO) as a means of coding patient phenotypes. The HPO provides a standardised vocabulary and captures relationships between disease features. The use of such ontologically encoded data is widespread in bioinformatics, with ontologies defining relationships between concepts in hundreds of subfields. However, there has been a dearth of tools for manipulating and analysing ontological data.

Human Pol III misregulation is linked to tumour transformation, neurodegenerative and developmental disorders, and increased sensitivity to viral infections. Pol III inhibition increases longevity in different animals but also promotes intracellular bacterial growth owing to its role in the immune system.
