Under certain environmental conditions, it has massive outbreaks, resulting in attacks of healthy trees, becoming a forest pest. It has been proposed that the bark beetle’s microbiome plays a key role in the insect’s ecology, providing nutrients, inhibiting pathogens, and degrading tree defense compounds, among other probable traits. During a study of bacterial associates from I. typographus, we isolated three strains identified as Pseudomonas from different beetle life stages. In this work, we aimed to reveal the taxonomic status of these bacterial strains and to sequence and annotate their genomes to mine possible traits related to a role within the bark beetle holobiont. -

Summary Despite its devastating consequences, liver fibrosis has no treatments. Genome engineering and a hepatic organoid system was used to produce the first in vitro model for human liver fibrosis. Hepatic organoids engineered to express the most common causative mutation for Autosomal Recessive Polycystic Kidney Disease (ARPKD) developed the key features of ARPKD liver pathology (abnormal bile ducts and hepatic fibrosis) in only 21 days. -
Epidemiology of Mucopolysaccharidoses Update
diagnostics Review Epidemiology of Mucopolysaccharidoses Update Betul Celik 1,2 , Saori C. Tomatsu 2 , Shunji Tomatsu 1 and Shaukat A. Khan 1,* 1 Nemours/Alfred I. duPont Hospital for Children, Wilmington, DE 19803, USA; [email protected] (B.C.); [email protected] (S.T.) 2 Department of Biological Sciences, University of Delaware, Newark, DE 19716, USA; [email protected] * Correspondence: [email protected]; Tel.: +302-298-7335; Fax: +302-651-6888 Abstract: Mucopolysaccharidoses (MPS) are a group of lysosomal storage disorders caused by a lysosomal enzyme deficiency or malfunction, which leads to the accumulation of glycosaminoglycans in tissues and organs. If not treated at an early stage, patients have various health problems, affecting their quality of life and life-span. Two therapeutic options for MPS are widely used in practice: enzyme replacement therapy and hematopoietic stem cell transplantation. However, early diagnosis of MPS is crucial, as treatment may be too late to reverse or ameliorate the disease progress. It has been noted that the prevalence of MPS and each subtype varies based on geographic regions and/or ethnic background. Each type of MPS is caused by a wide range of the mutational spectrum, mainly missense mutations. Some mutations were derived from the common founder effect. In the previous study, Khan et al. 2018 have reported the epidemiology of MPS from 22 countries and 16 regions. In this study, we aimed to update the prevalence of MPS across the world. We have collected and investigated 189 publications related to the prevalence of MPS via PubMed as of December 2020. In total, data from 33 countries and 23 regions were compiled and analyzed. -

An Overview of the Role of Hdacs in Cancer Immunotherapy
International Journal of Molecular Sciences Review Immunoepigenetics Combination Therapies: An Overview of the Role of HDACs in Cancer Immunotherapy Debarati Banik, Sara Moufarrij and Alejandro Villagra * Department of Biochemistry and Molecular Medicine, School of Medicine and Health Sciences, The George Washington University, 800 22nd St NW, Suite 8880, Washington, DC 20052, USA; [email protected] (D.B.); [email protected] (S.M.) * Correspondence: [email protected]; Tel.: +(202)-994-9547 Received: 22 March 2019; Accepted: 28 April 2019; Published: 7 May 2019 Abstract: Long-standing efforts to identify the multifaceted roles of histone deacetylase inhibitors (HDACis) have positioned these agents as promising drug candidates in combatting cancer, autoimmune, neurodegenerative, and infectious diseases. The same has also encouraged the evaluation of multiple HDACi candidates in preclinical studies in cancer and other diseases as well as the FDA-approval towards clinical use for specific agents. In this review, we have discussed how the efficacy of immunotherapy can be leveraged by combining it with HDACis. We have also included a brief overview of the classification of HDACis as well as their various roles in physiological and pathophysiological scenarios to target key cellular processes promoting the initiation, establishment, and progression of cancer. Given the critical role of the tumor microenvironment (TME) towards the outcome of anticancer therapies, we have also discussed the effect of HDACis on different components of the TME. We then have gradually progressed into examples of specific pan-HDACis, class I HDACi, and selective HDACis that either have been incorporated into clinical trials or show promising preclinical effects for future consideration. -

E-mail: [email protected] What was known? • Vorinostat is a histone deacetylase inhibitor. • It is an FDA approved drug for the treatment of cutaneous T cell lymphoma. Introduction of Vorinostat is approximately 9. Vorinostat is slightly Vorinostat is a histone deacetylase (HDAC) inhibitor, soluble in water, alcohol, isopropanol and acetone and is structurally belonging to the hydroxymate group. Other completely soluble in dimethyl sulfoxide. drugs in this group include Givinostat, Abexinostat, Mechanism of action Panobinostat, Belinostat and Trichostatin A. These Vorinostat is a broad inhibitor of HDAC activity and inhibits are an emergency class of drugs with potential anti- class I and class II HDAC enzymes.[2,3] However, Vorinostat neoplastic activity. These drugs were developed with the does not inhibit HDACs belonging to class III. Based on realization that apart from genetic mutation, alteration crystallographic studies, it has been seen that Vorinostat of HDAC enzymes affected the phenotypic and genotypic binds to the zinc atom of the catalytic site of the HDAC expression in cells, which in turn lead to disturbed enzyme with the phenyl ring of Vorinostat projecting out of homeostasis and neoplastic growth. -
Biotechnology Worldwide
Biotechnology Worldwide There are several countries that are making special efforts to both develop and capitalise on Biotechnology. Chief amongst them is America, though cutting edge work is also going on in the UK, Ireland, Germany, Korea, Singapore, China and Japan. • America is the world leader in biotechnology, it has 1,379 biotechnology companies and employs 174,000 people. It spends £9 billion on research into biotechnology. • The European market for goods and services dependent on biotechnology is currently estimated at £30 billion and is forecast to exceed £100 billion by the year 2005 • The UK leads Europe in biotechnology and employs 19,000 people • The UK has 300 dedicated biotechnology companies and a further 250-300 involved in broader bioscience related activities • The industrial sectors which stand to benefit from biotechnology are pharmaceutical, agriculture, food and drink, chemicals and environmental technologies • Germany is the second strongest country in Europe, with 332 companies but fewer products in development than the UK. UK The UK biotechnology industry is regarded as second only to the huge effort taking place in the States. UK biotechnology companies generate over a billion pounds in revenue; half of this is pumped back into research and development. The industry has particular strengths, for example: • Britain was a key player in the world wide project of sequencing the 30,000 genes of the human genome. The announcement of the first working draft of the human genome marks a significant step forward in our understanding of the way in which we understand and develop treatments for incurable genetic conditions. -
Comment Letter
July 23, 2008 Subject: Follow-up on July 22 Meeting Dr. Sirri et al.: I thank you for meeting with Ken Salomon, John Welborn and me yesterday afternoon to discuss Reg SHO, naked short selling and the SEC's recent emergency order. As a follow-up, I want to emphasize the following points: 1. OSTK continues to believe that it is critical that the SEC extend the pre-borrow requirement of the emergency order to the entire market, not just the 19 select companies. OSTK requests that the SEC promptly undertake swift rulemaking so that this protection applies fairly across the market. 2. OSTK continues to support the prompt and full elimination of the option market maker exception, an exception that swallows up the good intentions of Reg SHO. During yesterday's meeting, we discussed the relationship between the markets for equities and their corresponding derivatives (including listed options). You stated that options market makers enjoy an exception from the Reg SHO requirement that they locate and/or deliver shares when hedging against options positions. I am not sure that I would read Reg SHO to say that. However, under your theory, if an options market maker sells a put with a 6- month expiration, then that same market maker has the legal right to naked short and fail to deliver an equivalent amount of the underlying equity (leaving the option market maker "delta neutral”) for six months. This exception is unnecessary and open to abuse/manipulation, particularly with the married puts that often occur in Reg SHO threshold securities. -

Somatostatin Analogues in the Treatment of Neuroendocrine Tumors: Past, Present and Future
International Journal of Molecular Sciences Review Somatostatin Analogues in the Treatment of Neuroendocrine Tumors: Past, Present and Future Anna Kathrin Stueven 1, Antonin Kayser 1, Christoph Wetz 2, Holger Amthauer 2, Alexander Wree 1, Frank Tacke 1, Bertram Wiedenmann 1, Christoph Roderburg 1,* and Henning Jann 1 1 Charité, Campus Virchow Klinikum and Charité, Campus Mitte, Department of Hepatology and Gastroenterology, Universitätsmedizin Berlin, 10117 Berlin, Germany; [email protected] (A.K.S.); [email protected] (A.K.); [email protected] (A.W.); [email protected] (F.T.); [email protected] (B.W.); [email protected] (H.J.) 2 Charité, Campus Virchow Klinikum and Charité, Campus Mitte, Department of Nuclear Medicine, Universitätsmedizin Berlin, 10117 Berlin, Germany; [email protected] (C.W.); [email protected] (H.A.) * Correspondence: [email protected]; Tel.: +49-30-450-553022 Received: 3 May 2019; Accepted: 19 June 2019; Published: 22 June 2019 Abstract: In recent decades, the incidence of neuroendocrine tumors (NETs) has steadily increased. Due to the slow-growing nature of these tumors and the lack of early symptoms, most cases are diagnosed at advanced stages, when curative treatment options are no longer available. Prognosis and survival of patients with NETs are determined by the location of the primary lesion, biochemical functional status, differentiation, initial staging, and response to treatment. Somatostatin analogue (SSA) therapy has been a mainstay of antisecretory therapy in functioning neuroendocrine tumors, which cause various clinical symptoms depending on hormonal hypersecretion. Beyond symptomatic management, recent research demonstrates that SSAs exert antiproliferative effects and inhibit tumor growth via the somatostatin receptor 2 (SSTR2). -
1 Therapeutic Antibodies – from Past to Future Stefan Dubel¨ and Janice M
1 1 Therapeutic Antibodies – from Past to Future Stefan Dubel¨ and Janice M. Reichert 1.1 An Exciting Start – and a Long Trek In the late nineteenth century, the German army doctor Emil von Behring (1854–1917), later the first Nobel Laureate for Medicine, pioneered the thera- peutic application of antibodies. He used blood serum for the treatment of tetanus and diphtheria (‘‘Blutserumtherapie’’). When his data were published in 1890 [1], very little was known about the factors or mechanisms involved in immune defense. Despite this, his smart conclusion was that a human body needs some defense mechanism to fight foreign toxic substances and that these substances should be present in the blood – and therefore can be prepared from serum and used for therapy against toxins or infections. His idea worked, and the success allowed him to found the first ‘‘biotech’’ company devoted to antibody-based therapy in 1904 – using his Nobel Prize money as ‘‘venture capital.’’ The company is still active in the business today as part of CSLBehring. In 1908, Paul Ehrlich, the father of hematology [2] and the first consistent concept of immunology (‘‘lateral chain theory,’’ Figure 1.1d [3]), was awarded the second Nobel Prize related to antibody therapeutics for his groundbreaking work on serum, ‘‘particularly to the valency determination of sera preparations.’’ Ehrlich laid the foundations of antibody generation by performing systematic research on immunization schedules and their efficiency, and he was the first to describe different immunoglobulin subclasses. He also coined the phrases ‘‘passive vaccination’’ and ‘‘active vaccination.’’ His lateral chain theory (‘‘Seitenketten,’’ sometimes misleadingly translated to ‘‘side-chain theory’’) postulated chemical receptors produced by blood cells that fitted intruding toxins (antigens).
