The modern globalised world gives us overcome barriers, whether geographical, administrative, unique opportunities that stem from interdisciplinary, or sometimes cultural, requiring the collaboration of multinational partnerships, and taking advantage of them patients, healthcare professionals, managers, and society is a key part of developing projects with real impact. in general. IDIVAL, as a Healthcare Research Institute accredited by the Carlos III Health Institute, encouraging translational research and innovation as a foundation for improving patient care, must have an international outlook. This cross-border vision must coexist with a integrating vision that lets the different areas that could add value María Luisa Real González to healthcare research in Cantabria contribute to IDIVAL.

In a small Autonomous research in Spain. Its main distinguishing features include Community like ours, it is only by working together the search for excellence and innovation, always focused (hospitals, primary care, university and private enterprise) on improving the health of our citizens. that we can continue moving forwards to attract resources and scientific talent. 2016 was a productive year for IDIVAL. Among its achievements, in 2016 IDIVAL produced nearly 500 indexed publications, with a very high average impact factor (3.89), and 30 articles published in journals with an impact factor higher than 10. It continued to attract external resources, with 80 competitive research projects and 175 open clinical trials. This is an important point, because it shows we are competitive and contributes to our sustainability, for example enabling us to increase the number of post-MIR contracts and grants to research groups. A significant figure was the record number of competitive research projects granted by the Carlos III Health Institute in the 2016 campaign. However, in an increasingly competitive environment, we must be aware that IDIVAL can only be sustainable and continue to expand if we consolidate repeated access to European projects. This must be one of our main challenges in the coming years. To conclude, I will comment on some of the initiatives developed specifically in IDIVAL in 2016 that we are particularly proud of. We launched the COLABORA campaign, designed to attract altruistic, transparent donations for research, something our region was clearly lacking.

CMT patients typically show slowly progressive muscle weakness and sensory loss in a distal dominant pattern in childhood. The diagnosis of CMT is based on clinical symptoms, electrophysiological examinations, and genetic testing. Advances in genetic testing technology have revealed the genetic heterogeneity of CMT; more than 100 genes containing the disease causative mutations have been identified. Because a single genetic alteration in CMT leads to progressive neurodegeneration, studies of CMT patients and their respective models revealed the genotype-phenotype relationships of targeted genes. Conventionally, rodents and cell lines have often been used to study the pathogenesis of CMT. Recently, Drosophila has also attracted attention as a CMT model. In this review, we outline the clinical characteristics of CMT, describe the advantages and disadvantages of using Drosophila in CMT studies, and introduce recent advances in CMT research that successfully applied the use of Drosophila, in areas such as molecules associated with mitochondria, endosomes/lysosomes, transfer RNA, axonal transport, and glucose metabolism.

Chapter 5 DROSOPHILA AS A MODEL FOR CMT PERIPHERAL NEUROPATHY: MUTATIONS IN TRNA SYNTHETASES AS AN EXAMPLE Georg Steffes1 and Erik Storkebaum1,* 1Molecular Neurogenetics Laboratory, Max Planck Institute for Molecular Biomedicine, Muenster, Germany ABSTRACT Charcot-Marie-Tooth (CMT) disease is characterized by the degeneration of peripheral motor and sensory neurons, leading to progressive muscle weakness and wasting, and sensory loss. Electrophysiological and pathological criteria allow the distinction between demyelinating, axonal and intermediate forms of CMT. The disease is genetically heterogeneous, with currently more than 30 genes causally linked to CMT. The molecular underpinnings of the peripheral motor and sensory neuropathy are poorly understood, and there is no effective drug treatment available. In this chapter, we discuss the use of Drosophila melanogaster as a genetic model organism for CMT. Major advantages include the possibility to study the effect of CMT-associated mutant proteins on motor and sensory neurons in their physiological context, and its suitability to perform genetic screens.

Sablina * 1 VIB-KU Leuven Center for Cancer Biology, VIB, Herestraat 49, 3000 Leuven, Belgium; [email protected] (R.N.S.); [email protected] (M.F.B.) 2 Department of Oncology, KU Leuven, Herestraat 49, 3000 Leuven, Belgium * Correspondence: [email protected] These authors contributed equally to the work. y Received: 7 April 2020; Accepted: 23 April 2020; Published: 25 April 2020 Abstract: Ubiquitination is a versatile and dynamic post-translational modification in which single ubiquitin molecules or polyubiquitin chains are attached to target proteins, giving rise to mono- or poly-ubiquitination, respectively. The majority of research in the ubiquitin field focused on degradative polyubiquitination, whereas more recent studies uncovered the role of single ubiquitin modification in important physiological processes. Monoubiquitination can modulate the stability, subcellular localization, binding properties, and activity of the target proteins. Understanding the function of monoubiquitination in normal physiology and pathology has important therapeutic implications, as alterations in the monoubiquitin pathway are found in a broad range of genetic diseases. This review highlights a link between monoubiquitin signaling and the pathogenesis of genetic disorders. Keywords: ubiquitin system; genetic diseases; ubiquitin ligase; deubiquitinases; monoubiquitin signaling; vesicular trafficking; protein complex formation 1. Introduction Ubiquitination is a reversible post-translational modification process during which the highly conserved 76-aminoacid protein ubiquitin is conjugated to target proteins. Ubiquitin can be conjugated to a protein substrate via distinct mechanisms.

We studied a large family from a rural eastern Canadian community, with multiple individuals suffering from a condition clinically most similar to autosomal recessive axonal CMT, or AR-CMT2. Homozygosity mapping with high-density SNP genotyping of six affected individuals from the family excluded 23 known genes for various subtypes of CMT and instead identified a single homozygous region on chromosome 9, at 122,423,730–129,841,977 Mbp, shared identical by state in all six affected individuals. A homozygous pathogenic variant was identified in the gene encoding leucine rich repeat and sterile alpha motif 1 (LRSAM1) by direct DNA sequencing of genes within the region in affected DNA samples.

  • Comparative Analysis of the Ubiquitin-Proteasome System in Homo Sapiens and Saccharomyces Cerevisiae
    Comparative Analysis of the Ubiquitin-proteasome system in Homo sapiens and Saccharomyces cerevisiae Inaugural-Dissertation zur Erlangung des Doktorgrades der Mathematisch-Naturwissenschaftlichen Fakultät der Universität zu Köln vorgelegt von Hartmut Scheel aus Rheinbach Köln, 2005 Berichterstatter: Prof. Dr. R. Jürgen Dohmen Prof. Dr. Thomas Langer Dr. Kay Hofmann Tag der mündlichen Prüfung: 18.07.2005 Zusammenfassung I Zusammenfassung Das Ubiquitin-Proteasom System (UPS) stellt den wichtigsten Abbauweg für intrazelluläre Proteine in eukaryotischen Zellen dar. Das abzubauende Protein wird zunächst über eine Enzym-Kaskade mit einer kovalent gebundenen Ubiquitinkette markiert. Anschließend wird das konjugierte Substrat vom Proteasom erkannt und proteolytisch gespalten. Ubiquitin besitzt eine Reihe von Homologen, die ebenfalls posttranslational an Proteine gekoppelt werden können, wie z.B. SUMO und NEDD8. Die hierbei verwendeten Aktivierungs- und Konjugations-Kaskaden sind vollständig analog zu der des Ubiquitin- Systems. Es ist charakteristisch für das UPS, daß sich die Vielzahl der daran beteiligten Proteine aus nur wenigen Proteinfamilien rekrutiert, die durch gemeinsame, funktionale Homologiedomänen gekennzeichnet sind. Einige dieser funktionalen Domänen sind auch in den Modifikations-Systemen der Ubiquitin-Homologen zu finden, jedoch verfügen diese Systeme zusätzlich über spezifische Domänentypen. Homologiedomänen lassen sich als mathematische Modelle in Form von Domänen- deskriptoren (Profile) beschreiben. Diese Deskriptoren können wiederum dazu verwendet werden, mit Hilfe geeigneter Verfahren eine gegebene Proteinsequenz auf das Vorliegen von entsprechenden Homologiedomänen zu untersuchen. Da die im UPS involvierten Homologie- domänen fast ausschließlich auf dieses System und seine Analoga beschränkt sind, können domänen-spezifische Profile zur Katalogisierung der UPS-relevanten Proteine einer Spezies verwendet werden. Auf dieser Basis können dann die entsprechenden UPS-Repertoires verschiedener Spezies miteinander verglichen werden.

Patients with early onset PD (EOPD) are more susceptible to genetic factors. We systematically examined the overlaps between E3 ubiquitin ligase genes and EOPD. Methods A total of 695 EOPD patients were sequenced with whole exome sequencing. Aggregate burden for rare variants (Minor allele frequency <0.001 and <0.0001) in a total of 44 E3 ubiquitin ligase genes causing disorders involved in the nervous system were analyzed. Results There was signicant enrichment of the rare and rare damaging variants in the E3 ubiquitin ligase genes in EOPD patients.

Kingdom (n = 120), and one in Iowa (n = 100), in whom a targeted CMT NGS panel had been NPub.org/wkykkn requested as a diagnostic test. PMP22 duplication/deletion was previously excluded in de- myelinating cases. We reviewed the genetic and clinical data upon completion of the diagnostic process. Results After targeted NGS sequencing, a definite molecular diagnosis, defined as a pathogenic or likely pathogenic variant, was reached in 30% of cases (n = 67). The diagnostic rate was similar in London (32%) and Iowa (29%). Variants of unknown significance were found in an additional 33% of cases. Mutations in GJB1, MFN2, and MPZ accounted for 39% of cases that received genetic confirmation, while the remainder of positive cases had mutations in diverse genes, including SH3TC2, GDAP1, IGHMBP2, LRSAM1, FDG4, and GARS, and another 12 less common genes.
