Received: 23 April 2012; in revised form: 15 June 2012 / Accepted: 27 June 2012 / Published: 6 July 2012 Abstract: Since the isolation of Bacillus anthracis exotoxins in the 1960s, the detrimental activity of edema factor (EF) was considered as adenylyl cyclase activity only. Yet the catalytic site of EF was recently shown to accomplish cyclization of cytidine 5′-triphosphate, uridine 5′-triphosphate and inosine 5′-triphosphate, in addition to adenosine 5′-triphosphate. This review discusses the broad EF substrate specificity and possible implications of intracellular accumulation of cyclic cytidine 3′:5′-monophosphate, cyclic uridine 3′:5′-monophosphate and cyclic inosine 3′:5′-monophosphate on cellular functions vital for host defense. In particular, cAMP-independent mechanisms of action of EF on host cell signaling via protein kinase A, protein kinase G, phosphodiesterases and CNG channels are discussed. -

Peking University-Juntendo University Joint Symposium on Cancer Research and Treatment ADAM28 (A Disintegrin and Metalloproteinase 28) in Cancer Cell Proliferation and Progression
Whatʼs New from Juntendo University, Tokyo Juntendo Medical Journal 2017. 63(5), 322-325 Peking University - Juntendo University Joint Symposium on Cancer Research and Treatment ADAM28 (a Disintegrin and Metalloproteinase 28) in Cancer Cell Proliferation and Progression YASUNORI OKADA* *Department of Pathophysiology for Locomotive and Neoplastic Diseases, Juntendo University Graduate School of Medicine, Tokyo, Japan A disintegrinandmetalloproteinase 28 (ADAM28) is overexpressedpredominantlyby carcinoma cells in more than 70% of the non-small cell lung carcinomas, showing positive correlations with carcinoma cell proliferation and metastasis. ADAM28 cleaves insulin-like growth factor binding protein-3 (IGFBP-3) in the IGF-I/IGFBP-3 complex, leading to stimulation of cell proliferation by intact IGF-I released from the complex. ADAM28 also degrades von Willebrand factor (VWF), which induces apoptosis in human carcinoma cell lines with negligible ADAM28 expression, andthe VWF digestionby ADAM28-expressing carcinoma cells facilitates them to escape from VWF-induced apoptosis, resulting in promotion of metastasis. We have developed human antibodies against ADAM28 andshown that one of them significantly inhibits tumor growth andmetastasis using lung adenocarcinoma cells. Our data suggest that ADAM28 may be a new molecular target for therapy of the patients with ADAM28-expressing non-small cell lung carcinoma.

Common Gene Polymorphisms Associated with Thrombophilia
Chapter 5 Common Gene Polymorphisms Associated with Thrombophilia Christos Yapijakis, Zoe Serefoglou and Constantinos Voumvourakis Additional information is available at the end of the chapter http://dx.doi.org/10.5772/61859 Abstract Genetic association studies have revealed a correlation between DNA variations in genes encoding factors of the hemostatic system and thrombosis-related disease. Certain var‐ iant alleles of these genes that affect either gene expression or function of encoded protein are known to be genetic risk factors for thrombophilia. The chapter presents the current genetics and molecular biology knowledge of the most important DNA polymorphisms in thrombosis-related genes encoding coagulation factor V (FV), coagulation factor II (FII), coagulation factor XII (FXII), coagulation factor XIII A1 subunit (FXIIIA1), 5,10- methylene tetrahydrofolate reductase (MTHFR), serpine1 (SERPINE1), angiotensin I-con‐ verting enzyme (ACE), angiotensinogen (AGT), integrin A2 (ITGA2), plasma carboxypeptidase B2 (CPB2), platelet glycoprotein Ib α polypeptide (GP1BA), thrombo‐ modulin (THBD) and protein Z (PROZ). The molecular detection methods of each DNA polymorphism is presented, in addition to the current knowledge regarding its influence on thrombophilia and related thrombotic events, including stroke, myocardial infarction, deep vein thrombosis, spontaneous abortion, etc. In addition, best thrombosis prevention strategies with a combination of genetic counseling and molecular testing are discussed.

Abstract 350 words maximum: (PLEASE TYPE) N-Myc Induces neuroblastoma by regulating the expression of target genes and proteins, and N-Myc protein is degraded by Fbxw7 and NEDD4 and stabilized by Aurora A. The class lla histone deacetylase HDAC5 suppresses gene transcription, and blocks myoblast and leukaemia cell differentiation. While histone H3 lysine 4 (H3K4) trimethylation at target gene promoters is a pre-requisite for Myc· induced transcriptional activation, WDRS, as a histone H3K4 methyltransferase presenter, is required for H3K4 methylation and transcriptional activation mediated by a histone H3K4 methyltransferase complex. Here, I investigated the roles of HDAC5 and WDR5 in N-Myc overexpressing neuroblastoma. I have found that N-Myc upregulates HDAC5 protein expression, and that HDAC5 represses NEDD4 gene expression, increases Aurora A gene expression and consequently upregulates N-Myc protein expression in neuroblastoma cells. -

M.S., Department of Biochemistry and Molecular Biology, Wright State University, 2007 Differential effect of TAp63γ mutants on transactivation of p53 and/or p63 responsive genes and their effects on global gene expression. p63, a member of the p53 gene family, known to play a role in development, has more recently also been implicated in cancer progression. Mice lacking p63 exhibit severe developmental defects such as limb truncations, abnormal skin, and absence of hair follicles, teeth, and mammary glands. Germline missense mutations of p63 have been shown to be responsible for several human developmental syndromes including SHFM, EEC and ADULT syndromes and are associated with anomalies in the development of organs of epithelial origin. -

5' Untranslated Region Elements Show High Abundance and Great
International Journal of Molecular Sciences Article 0 5 Untranslated Region Elements Show High Abundance and Great Variability in Homologous ABCA Subfamily Genes Pavel Dvorak 1,2,* , Viktor Hlavac 2,3 and Pavel Soucek 2,3 1 Department of Biology, Faculty of Medicine in Pilsen, Charles University, 32300 Pilsen, Czech Republic 2 Biomedical Center, Faculty of Medicine in Pilsen, Charles University, 32300 Pilsen, Czech Republic; [email protected] (V.H.); [email protected] (P.S.) 3 Toxicogenomics Unit, National Institute of Public Health, 100 42 Prague, Czech Republic * Correspondence: [email protected]; Tel.: +420-377593263 Received: 7 October 2020; Accepted: 20 November 2020; Published: 23 November 2020 Abstract: The 12 members of the ABCA subfamily in humans are known for their ability to transport cholesterol and its derivatives, vitamins, and xenobiotics across biomembranes. Several ABCA genes are causatively linked to inborn diseases, and the role in cancer progression and metastasis is studied intensively. The regulation of translation initiation is implicated as the major mechanism in the processes of post-transcriptional modifications determining final protein levels. In the current bioinformatics study, we mapped the features of the 50 untranslated regions (50UTR) known to have the potential to regulate translation, such as the length of 50UTRs, upstream ATG codons, upstream open-reading frames, introns, RNA G-quadruplex-forming sequences, stem loops, and Kozak consensus motifs, in the DNA sequences of all members of the subfamily. Subsequently, the conservation of the features, correlations among them, ribosome profiling data as well as protein levels in normal human tissues were examined. The 50UTRs of ABCA genes contain above-average numbers of upstream ATGs, open-reading frames and introns, as well as conserved ones, and these elements probably play important biological roles in this subfamily, unlike RG4s. -
Identification of New Substrates and Physiological Relevance
Université de Montréal The Multifaceted Proprotein Convertases PC7 and Furin: Identification of New Substrates and Physiological Relevance Par Stéphanie Duval Biologie Moléculaire, Faculté de médecine Thèse présentée en vue de l’obtention du grade de Philosophiae doctor (Ph.D) en Biologie moléculaire, option médecine cellulaire et moléculaire Avril 2020 © Stéphanie Duval, 2020 Résumé Les proprotéines convertases (PCs) sont responsables de la maturation de plusieurs protéines précurseurs et sont impliquées dans divers processus biologiques importants. Durant les 30 dernières années, plusieurs études sur les PCs se sont traduites en succès cliniques, toutefois les fonctions spécifiques de PC7 demeurent obscures. Afin de comprendre PC7 et d’identifier de nouveaux substrats, nous avons généré une analyse protéomique des protéines sécrétées dans les cellules HuH7. Cette analyse nous a permis d’identifier deux protéines transmembranaires de fonctions inconnues: CASC4 et GPP130/GOLIM4. Au cours de cette thèse, nous nous sommes aussi intéressé au rôle de PC7 dans les troubles comportementaux, grâce à un substrat connu, BDNF. Dans le chapitre premier, je présenterai une revue de la littérature portant entre autres sur les PCs. Dans le chapitre II, l’étude de CASC4 nous a permis de démontrer que cette protéine est clivée au site KR66↓NS par PC7 et Furin dans des compartiments cellulaires acides. Comme CASC4 a été rapporté dans des études de cancer du sein, nous avons généré des cellules MDA- MB-231 exprimant CASC4 de type sauvage et avons démontré une diminution significative de la migration et de l’invasion cellulaire. Ce phénotype est causé notamment par une augmentation du nombre de complexes d’adhésion focale et peut être contrecarré par la surexpression d’une protéine CASC4 mutante ayant un site de clivage optimale par PC7/Furin ou encore en exprimant une protéine contenant uniquement le domaine clivé N-terminal.
