The Significance of the Evolutionary Relationship of Prion Proteins and ZIP Transporters in Health and Disease
The Significance of the Evolutionary Relationship of Prion Proteins and ZIP Transporters in Health and Disease by Sepehr Ehsani A thesis submitted in conformity with the requirements for the degree of Doctor of Philosophy Department of Laboratory Medicine and Pathobiology University of Toronto © Copyright by Sepehr Ehsani 2012 The Significance of the Evolutionary Relationship of Prion Proteins and ZIP Transporters in Health and Disease Sepehr Ehsani Doctor of Philosophy Department of Laboratory Medicine and Pathobiology University of Toronto 2012 Abstract The cellular prion protein (PrPC) is unique amongst mammalian proteins in that it not only has the capacity to aggregate (in the form of scrapie PrP; PrPSc) and cause neuronal degeneration, but can also act as an independent vector for the transmission of disease from one individual to another of the same or, in some instances, other species. Since the discovery of PrPC nearly thirty years ago, two salient questions have remained largely unanswered, namely, (i) what is the normal function of the cellular protein in the central nervous system, and (ii) what is/are the factor(s) involved in the misfolding of PrPC into PrPSc? To shed light on aspects of these questions, we undertook a discovery-based interactome investigation of PrPC in mouse neuroblastoma cells (Chapter 2), and among the candidate interactors, identified two members of the ZIP family of zinc transporters (ZIP6 and ZIP10) as possessing a PrP-like domain. Detailed analyses revealed that the LIV-1 subfamily of ZIP transporters (to which ZIPs 6 and 10 belong) are in fact the evolutionary ancestors of prions (Chapter 3). -

The Classification of Esterases: an Important Gene Family Involved in Insecticide Resistance - a Review
Mem Inst Oswaldo Cruz, Rio de Janeiro, Vol. 107(4): 437-449, June 2012 437 The classification of esterases: an important gene family involved in insecticide resistance - A Review Isabela Reis Montella1,2, Renata Schama1,2,3/+, Denise Valle1,2,3 1Laboratório de Fisiologia e Controle de Artrópodes Vetores, Instituto Oswaldo Cruz-Fiocruz, Av. Brasil 4365, 21040-900 Rio de Janeiro, RJ, Brasil 2Instituto de Biologia do Exército, Rio de Janeiro, RJ, Brasil 3Instituto Nacional de Ciência e Tecnologia em Entomologia Molecular, Rio de Janeiro, RJ, Brasil The use of chemical insecticides continues to play a major role in the control of disease vector populations, which is leading to the global dissemination of insecticide resistance. A greater capacity to detoxify insecticides, due to an increase in the expression or activity of three major enzyme families, also known as metabolic resistance, is one major resistance mechanisms. The esterase family of enzymes hydrolyse ester bonds, which are present in a wide range of insecticides; therefore, these enzymes may be involved in resistance to the main chemicals employed in control programs. Historically, insecticide resistance has driven research on insect esterases and schemes for their classification. Currently, several different nomenclatures are used to describe the esterases of distinct species and a universal standard classification does not exist. The esterase gene family appears to be rapidly evolving and each insect species has a unique complement of detoxification genes with only a few orthologues across species. The examples listed in this review cover different aspects of their biochemical nature. However, they do not appear to contribute to reliably distinguish among the different resistance mechanisms. -
The Astacin Family of Metalloendopeptidases

BEYNON2 ’ Department of Biochemistry and Molecular Biology, The Pennsylvania State University College of Medicine, Hershey, Pennsylvania 17033 Department of Biochemistry and Applied Molecular Biology, University of Manchester Institute of ‘Science and Technology, Manchester M60 1QD. United Kingdom (RECEIVEDMarch 23, 1995; ACCEPTED April19, 1995) Abstract The astacin family of metalloendopeptidases was recognized as a novel family of proteases in the 1990s. The cray- fish enzyme astacin was the first characterized and is one of the smallest members of the family. More than 20 members of the family have nowbeen identified. They have been detected in species ranging from hydra to hu- mans, in mature andin developmental systems. Proposed functions of these proteases include activation of growth factors, degradation of polypeptides, and processing of extracellular proteins. Astacin family proteases aresyn- thesized with NH,-terminal signal and proenzyme sequences, and many (such as meprins, BMP-1, folloid)con- tain multiple domains COOH-terminal to the protease domain. They are eithersecreted from cells or are plasma membrane-associated enzymes. They have some distinguishing features in addition to the signature sequencein the protease domain: HEXXHXXGFXHEXXRXDR. They have a unique typeof zinc binding, with pentacoor- dination, and a protease domain tertiary structure that contains common attributeswith serralysins, matrix me- talloendopeptidases, and snake venom proteases; they cleave peptide bonds in polypeptides such as insulin B chain and bradykinin andin proteins such as casein and gelatin; and theyhave arylamidase activity. -
Loss of the Dermis Zinc Transporter ZIP13 Promotes the Mildness Of
www.nature.com/scientificreports OPEN Loss of the dermis zinc transporter ZIP13 promotes the mildness of fbrosarcoma by inhibiting autophagy Mi-Gi Lee1,8, Min-Ah Choi2,8, Sehyun Chae3,8, Mi-Ae Kang4, Hantae Jo4, Jin-myoung Baek4, Kyu-Ree In4, Hyein Park4, Hyojin Heo4, Dongmin Jang5, Sofa Brito4, Sung Tae Kim6, Dae-Ok Kim 1,7, Jong-Soo Lee4, Jae-Ryong Kim2* & Bum-Ho Bin 4* Fibrosarcoma is a skin tumor that is frequently observed in humans, dogs, and cats. Despite unsightly appearance, studies on fbrosarcoma have not signifcantly progressed, due to a relatively mild tumor severity and a lower incidence than that of other epithelial tumors. Here, we focused on the role of a recently-found dermis zinc transporter, ZIP13, in fbrosarcoma progression. We generated two transformed cell lines from wild-type and ZIP13-KO mice-derived dermal fbroblasts by stably expressing the Simian Virus (SV) 40-T antigen. The ZIP13−/− cell line exhibited an impairment in autophagy, followed by hypersensitivity to nutrient defciency. The autophagy impairment in the ZIP13−/− cell line was due to the low expression of LC3 gene and protein, and was restored by the DNA demethylating agent, 5-aza-2’-deoxycytidine (5-aza) treatment. Moreover, the DNA methyltransferase activity was signifcantly increased in the ZIP13−/− cell line, indicating the disturbance of epigenetic regulations. Autophagy inhibitors efectively inhibited the growth of fbrosarcoma with relatively minor damages to normal cells in xenograft assay. Our data show that proper control over autophagy and zinc homeostasis could allow for the development of a new therapeutic strategy to treat fbrosarcoma. -
