Downloaded from Progressive encephalopathy with oedema, hypsarrhythmia and optic atrophy (PEHO) syndrome is a rare Mendelian phenotype comprising severe retardation, early onset epileptic seizures, optic nerve/cerebellar atrophy, pedal oedema, and early death. Atypical cases are often known as PEHO-like, and there is an overlap with ‘early infantile epileptic encephalopathy’. PEHO is considered to be recessive, but surprisingly since initial description in 1991, no causative recessive gene(s) have been described. http://brain.oxfordjournals.org/ Hence, we report a multiplex consanguineous family with the PEHO phenotype where affected individuals had a homozygous frame-shift deletion in CCDC88A (c.2313delT, p.Leu772Ãter). Analysis of cDNA extracted from patient lymphocytes unexpectedly failed to show non-sense mediated decay, and we demonstrate that the mutation produces a truncated protein lacking the crucial C-terminal half of CCDC88A (girdin). To further investigate the possible role of CCDC88A in human neurodevelopment we re- examined the behaviour and neuroanatomy of Ccdc88a knockout pups. These mice had mesial-temporal lobe epilepsy, micro- cephaly and corpus callosum deficiency, and by postnatal Day 21, microcephaly; the mice died at an early age. As the mouse knockout phenotype mimics the human PEHO phenotype this suggests that loss of CCDC88A is a cause of the PEHO phenotype, and that CCDC88A is essential for multiple aspects of normal human neurodevelopment. by guest on October 14, 2016 1 Cambridge Institute for Medical Research, University of Cambridge, Cambridge, CB2 0XY, UK 2 Department of Pathology, Centre for Neurological Disease and Cancer, Nagoya University Graduate School of Medicine, 65 Tsurumai-cho, Showa-ku, Nagoya, Aichi, 466N, Japan 3 North West Thames Regional Genetics Service, Level 8V, London North West Healthcare NHS Trust, Watford Road, Harrow, HA1 3UJ, UK 4 Department of Paediatric Neuroscience, Addenbrooke’s Hospital, Hills Rd, Cambridge, CB2 0QQ, UK Correspondence to: C.

Unlike most of AID/APOBEC, however, APOBEC2’s function remains elusive. Previous research has implicated APOBEC2 in diverse organisms and cellular processes such as muscle biology (in Mus musculus), regeneration (in Danio rerio), and development (in Xenopus laevis). APOBEC2 has also been implicated in cancer. However the enzymatic activity, substrate or physiological target(s) of APOBEC2 are unknown. For this thesis, I have combined Next Generation Sequencing (NGS) techniques with state-of-the-art molecular biology to determine the physiological targets of APOBEC2. Using a cell culture muscle differentiation system, and RNA sequencing (RNA-Seq) by polyA capture, I demonstrated that unlike the AID/APOBEC family member APOBEC1, APOBEC2 is not an RNA editor. Using the same system combined with enhanced Reduced Representation Bisulfite Sequencing (eRRBS) analyses I showed that, unlike the AID/APOBEC family member AID, APOBEC2 does not act as a 5-methyl-C deaminase.

  • Combinatorial Strategies Using CRISPR/Cas9 for Gene Mutagenesis in Adult Mice
    Combinatorial strategies using CRISPR/Cas9 for gene mutagenesis in adult mice Avery C. Hunker A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2019 Reading Committee: Larry S. Zweifel, Chair Sheri J. Mizumori G. Stanley McKnight Program Authorized to Offer Degree: Pharmacology 2 © Copyright 2019 Avery C. Hunker 3 University of Washington ABSTRACT Combinatorial strategies using CRISPR/Cas9 for gene mutagenesis in adult mice Avery C. Hunker Chair of the Supervisory Committee: Larry Zweifel Department of Pharmacology A major challenge to understanding how genes modulate complex behaviors is the inability to restrict genetic manipulations to defined cell populations or circuits. To circumvent this, we created a simple strategy for limiting gene knockout to specific cell populations using a viral-mediated, conditional CRISPR/SaCas9 system in combination with intersectional genetic strategies. A small single guide RNA (sgRNA) directs Staphylococcus aureus CRISPR-associated protein (SaCas9) to unique sites on DNA in a Cre-dependent manner resulting in double strand breaks and gene mutagenesis in vivo. To validate this technique we targeted nine different genes of diverse function in distinct cell types in mice and performed an array of analyses to confirm gene mutagenesis and subsequent protein loss, including IHC, cell-type specific DNA sequencing, electrophysiology, Western blots, and behavior. We show that these vectors are as efficient as conventional conditional gene knockout and provide a viable alternative to complex genetic crosses. This strategy provides additional benefits of 4 targeting gene mutagenesis to cell types previously difficult to isolate, and the ability to target genes in specific neural projections for gene inactivation.

We investigated the evolutionary pressures acting on almost all human protein-coding genes (N=11,667; 1:1 orthologs in primates) based on their divergence from those of early hominins, such as Neanderthals, and non-human primates. We confirm that genes encoding brain-related proteins are among the most strongly conserved protein-coding genes in the human genome. Combining our evolutionary pressure metrics for the protein- coding genome with recent datasets, we found that this conservation applied to genes functionally associated with the synapse and expressed in brain structures such as the prefrontal cortex and the cerebellum. Conversely, several genes presenting signatures commonly associated with positive selection appear as causing brain diseases or conditions, such as micro/macrocephaly, Joubert syndrome, dyslexia, and autism.

    Molecular Psychiatry (2014) 19, 41–49 & 2014 Macmillan Publishers Limited All rights reserved 1359-4184/14 www.nature.com/mp IMMEDIATE COMMUNICATION Genome-wide association study of alcohol dependence: significant findings in African- and European-Americans including novel risk loci J Gelernter1,2, HR Kranzler3, R Sherva4, L Almasy5, R Koesterer4, AH Smith1, R Anton6, UW Preuss7, M Ridinger8, D Rujescu7, N Wodarz8, P Zill9, H Zhao10,11 and LA Farrer4,12 We report a GWAS of alcohol dependence (AD) in European-American (EA) and African-American (AA) populations, with replication in independent samples of EAs, AAs and Germans. Our sample for discovery and replication was 16 087 subjects, the largest sample for AD GWAS to date. Numerous genome-wide significant (GWS) associations were identified, many novel. Most associations were population specific, but in several cases were GWS in EAs and AAs for different SNPs at the same locus,showing biological convergence across populations. We confirmed well-known risk loci mapped to alcohol-metabolizing enzyme genes, notably ADH1B (EAs: Arg48His, P ¼ 1.17 Â 10 À 31; AAs: Arg369Cys, P ¼ 6.33 Â 10 À 17) and ADH1C in AAs (Thr151Thr, P ¼ 4.94 Â 10 À 10), and identified novel risk loci mapping to the ADH gene cluster on chromosome 4 and extending centromerically beyond it to include GWS associations at LOC100507053 in AAs (P ¼ 2.63 Â 10 À 11), PDLIM5 in EAs (P ¼ 2.01 Â 10 À 8), and METAP in AAs (P ¼ 3.35 Â 10 À 8). We also identified a novel GWS association (1.17 Â 10 À 10) mapped to chromosome 2 at rs1437396, between MTIF2 and CCDC88A, across all of the EA and AA cohorts, with supportive gene expression evidence, and population-specific GWS for markers on chromosomes 5, 9 and 19.

Chemical Engineering Brigham Young University, 2014 Submitted to the Department of Biological Engineering in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Biological Engineering ABSTRACT Ovarian cancer is the fifth leading cause of cancer death for women in the United States, with only modest improvements in patient survival in the past few decades. Standard-of-care consists of surgical debulking followed by a combination of platinum and taxane agents, but relapse and resistance frequently occur.
