ROEDER Departments ofBiological Chemistry and Genetics, Division ofBiology and Biomedical Sciences, Washington University School ofMedicine, St. Louis, Missouri 63110 The four major adeno-associated virus type 2 (AAV2)-specific RNAs were mapped on the linear viral genome by a variety of biochemical techniques, including Si nuclease and exonuclease VII mapping, RNA gel-transfer hybridi- zation, and analysis of reverse transcriptase extension products. All the major AAV2 RNAs were derived from the minus DNA strand and had 3' termini at position 96. The nucleus-specific 4.3- and 3.6-kilobase (kb) RNAs had 5' termini at positions 6 and 19, respectively. The 5' terminus of the 2.6-kb RNA mapped to position 38.5. The predominant 2.3-kb AAV2 mRNA was spliced and contained a short leader sequence (approximately 50 nucleotides) which mapped to position 38.5, coincident with the 5' terminus of the 2.6-kb RNA. The 5' end of the body of the 2.3-kb RNA mapped to position 46.5. These results are discussed in terms of the involvement of single versus multiple promoters (for transcription) and RNA splicing mechanisms in the generation of the AAV2 RNAs. Mammalian DNA viruses have provided pow- In our earlier studies ofAAV2 (19), we defined erful models for the analysis and formulation of and partially characterized four predominant mechaisms of gene expression in eucaryotic AAV2 RNAs in virus-infected cells, indicating cells.

    IDENTIFICATION OF VIRULENCE DETERMINANTS OF MYCOBACTERIUM TUBERCULOSIS VIA GENETIC COMPARISONS OF A VIRULENT AND AN ATTENUATED STRAIN OF MYCOBACTERIUM TUBERCULOSIS. by ALICE HOY LAM LI B.Sc., The University of British Columbia, 2001 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIRMENT FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE STUDIES (Pathology) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) MARCH 2008 Alice Hoy Lam Li, 2008 i ABSTRACT Candidate virulence genes were sought through the genetic analyses of two strains of Mycobacterium tuberculosis, one virulent, H37Rv, one attenuated, H37Ra. Derived from the same parent, H37, genomic differences between strains were first examined via two-dimensional DNA technologies: two-dimensional bacterial genome display, and bacterial comparative genomic hybridisation. The two-dimensional technologies were optimised for mycobacterial use, but failed to yield reproducible genomic differences between the two strains. Expression differences between strains during their infection of murine bone-marrow-derived macrophages were then assessed using Bacterial Artificial Chromosome Fingerprint Arrays. This technique successfully identified expression differences between intracellular M. tuberculosis H37Ra and H37Rv, and six candidate genes were confirmed via quantitative real-time PCR for their differential expression at 168 hours post-infection. Genes identified to be upregulated in the attenuated H37Ra were frdB, frdC, and frdD. Genes upregulated in the virulent H37Rv were pks2, aceE, and Rv1571. Further qPCR analysis of these genes at 4 and 96h post-infection revealed that the frd operon (encoding for the fumarate reductase enzyme complex or FRD) was expressed at higher levels in the virulent H37Rv at earlier time points while the expression of aceE and pks2 was higher in the virulent strain throughout the course of infection.

  • Structural Study of the Acid Sphingomyelinase Protein Family
    Structural Study of the Acid Sphingomyelinase Protein Family Alexei Gorelik Department of Biochemistry McGill University, Montreal August 2017 A thesis submitted to McGill University in partial fulfillment of the requirements of the degree of Doctor of Philosophy © Alexei Gorelik, 2017 Abstract The acid sphingomyelinase (ASMase) converts the lipid sphingomyelin (SM) to ceramide. This protein participates in lysosomal lipid metabolism and plays an additional role in signal transduction at the cell surface by cleaving the abundant SM to ceramide, thus modulating membrane properties. These functions are enabled by the enzyme’s lipid- and membrane- interacting saposin domain. ASMase is part of a small family along with the poorly characterized ASMase-like phosphodiesterases 3A and 3B (SMPDL3A,B). SMPDL3A does not hydrolyze SM but degrades extracellular nucleotides, and is potentially involved in purinergic signaling. SMPDL3B is a regulator of the innate immune response and podocyte function, and displays a partially defined lipid- and membrane-modifying activity. I carried out structural studies to gain insight into substrate recognition and molecular functions of the ASMase family of proteins. Crystal structures of SMPDL3A uncovered the helical fold of a novel C-terminal subdomain, a slightly distinct catalytic mechanism, and a nucleotide-binding mode without specific contacts to their nucleoside moiety. The ASMase investigation revealed a conformational flexibility of its saposin domain: this module can switch from a detached, closed conformation to an open form which establishes a hydrophobic interface to the catalytic domain. This open configuration represents the active form of the enzyme, likely allowing lipid access to the active site. The SMPDL3B structure showed a narrow, boot-shaped substrate binding site that accommodates the head group of SM.

Received: 4 March 2020; Accepted: 2 April 2020; Published: 8 April 2020 Abstract: Vegetable oil is mainly composed of triacylglycerol (TAG), a storage lipid that serves as a major commodity for food and industrial purposes, as well as an alternative biofuel source. While TAG is typically not produced at significant levels in vegetative tissues, emerging evidence suggests that its accumulation in such tissues may provide one mechanism by which plants cope with abiotic stress. Different types of abiotic stress induce lipid remodeling through the action of specific lipases, which results in various alterations in membrane lipid composition. This response induces the formation of toxic lipid intermediates that cause membrane damage or cell death. However, increased levels of TAG under stress conditions are believed to function, at least in part, as a means of sequestering these toxic lipid intermediates. Moreover, the lipid droplets (LDs) in which TAG is enclosed also function as a subcellular factory to provide binding sites and substrates for the biosynthesis of bioactive compounds that protect against insects and fungi.

    Genomics of inherited bone marrow failure and myelodysplasia Michael Yu Zhang A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy University of Washington 2015 Reading Committee: Mary-Claire King, Chair Akiko Shimamura Marshall Horwitz Program Authorized to Offer Degree: Molecular and Cellular Biology 1 ©Copyright 2015 Michael Yu Zhang 2 University of Washington ABSTRACT Genomics of inherited bone marrow failure and myelodysplasia Michael Yu Zhang Chair of the Supervisory Committee: Professor Mary-Claire King Department of Medicine (Medical Genetics) and Genome Sciences Bone marrow failure and myelodysplastic syndromes (BMF/MDS) are disorders of impaired blood cell production with increased leukemia risk. BMF/MDS may be acquired or inherited, a distinction critical for treatment selection. Currently, diagnosis of these inherited syndromes is based on clinical history, family history, and laboratory studies, which directs the ordering of genetic tests on a gene-by-gene basis. However, despite extensive clinical workup and serial genetic testing, many cases remain unexplained. We sought to define the genetic etiology and pathophysiology of unclassified bone marrow failure and myelodysplastic syndromes. First, to determine the extent to which patients remained undiagnosed due to atypical or cryptic presentations of known inherited BMF/MDS, we developed a massively-parallel, next- generation DNA sequencing assay to simultaneously screen for mutations in 85 BMF/MDS genes. Querying 71 pediatric and adult patients with unclassified BMF/MDS using this assay revealed 8 (11%) patients with constitutional, pathogenic mutations in GATA2 , RUNX1 , DKC1 , or LIG4 . All eight patients lacked classic features or laboratory findings for their syndromes.

Circular sin- from both ends (unpublished data) led us to infer that recA pro- gle strands homologous to M13 DNA paired with a chimeric frag- ment when M13 sequences were located at the 3' end ofthe com- tein actively drives the formation ofheteroduplex DNA in one plementary strand but did not pair when the M13 sequences were direction.

  • The Effect of Nucleic Acid Modifications on Digestion by DNA Exonucleases by Greg Lohman, Ph.D., New England Biolabs, Inc
    be INSPIRED FEATURE ARTICLE drive DISCOVERY stay GENUINE The effect of nucleic acid modifications on digestion by DNA exonucleases by Greg Lohman, Ph.D., New England Biolabs, Inc. New England Biolabs offers a wide variety of exonucleases with a range of nucleotide structure specificity. Exonucleases can be active on ssDNA and/or dsDNA, initiate from the 5´ end and/or the 3´ end of polynucleotides, and can also act on RNA. Exonucleases have many applications in molecular biology, including removal of PCR primers, cleanup of plasmid DNA and production of ssDNA from dsDNA. In this article, we explore the activity of commercially available exonucleases on oligonucleotides that have chemical modifications added during phosphoramidite synthesis, including phosphorothioate diester bonds, 2´-modified riboses, modified bases, and 5´ and 3´ end modifications. We discuss how modifications can be used to selectively protect some polynucleotides from digestion in vitro, and which modifications will be cleaved like natural DNA. This information can be helpful for designing primers that are stable to exonucleases, protecting specific strands of DNA, and preparing oligonucleotides with modifications that will be resistant to rapid cleavage by common exonuclease activities. The ability of nucleases to hydrolyze phosphodi- of exonucleases available from NEB can be found Figure 1: ester bonds in nucleic acids is among the earliest in our selection chart, Common Applications of Examples of exonuclease directionality nucleic acid enzyme activities to be characterized Exonucleases and Non-specific Endonucleases, at → (1-6).
