Lucilene Delazari dos Santos Prof. Dr. André Schwambach Vieira Os membros da Comissão Examinadora acima assinaram a Ata de Defesa, que se encontra no processo de vida acadêmica do aluno DEDICATÓRIA Dedico essa dissertação aos meus pais, que foram o meu maior apoio nos momentos de angústia. Mãe, sеu cuidado, força е dedicação em olhar por mim, fоram os que deram,nos momentos mais difíceis, а esperança pаrа continuar seguindo em frente. Pai, suа presença significou segurança е certeza dе qυе não estou sozinha nessa caminhada. AGRADECIMENTOS À Fundação de Amparo à Pesquisa do Estado de São Paulo – FAPESP pelo apoio financeiro (Processo 2015/23049-0), concedida como ítem orçamentário do projeto Jovem Pesquisador ( 2013/08711-3). Se você está lendo essa página, é porque aquele ditado “no final tudo dá certo” de fato é verdadeiro, porque eu cheguei até aqui. Do processo seletivo, aprovação e conclusão do mestrado foram longos (e curtos) dois anos que acrescentaram além de um título de mestre, algumas rugas e cabelos brancos. Mas quem disse que seria fácil? E eu nem gostaria que tivesse sido! Se o fosse, a vida não teria me dado tantas pessoas maravilhosas, que de alguma forma, no seu jeito, me apoiaram e me fizeram seguir em frente. E são a esses que quero agradecer, do fundo e local mais sincero do meu coração. Primeiramente agradeço a Deus, que sempre olhou por mim, independente das vírgulas e reticências encontradas pelo caminho. Aos meus amados pais, Vilma e Wilson, pelo seu tempo, amor e dedicação em sempre cuidar de mim. Por não desistirem, por acreditarem que eu era capaz de chegar até aqui. A minha mãe, que tem uma força sobrenatural, guerreira, aquela que ajudou em me tornar a mulher que sou hoje. A minha família, que estão comigo desde o início, constituindo a base mais firme que alguém pode querer. Obrigada as tias e tios, por serem minhas segundas, terceiras e quartas mães e pais! A minha vozinha que ainda está aqui, sempre me amando e apoiando e aquela vózinha que já se foi, anjo de olhos azuis que tem grande participação na minha caminhada até aqui. Sem ela, não sei aonde estaria hoje. Ao meu orientador prof. Dr. Daniel Martins de Souza, que um dia me deu a oportunidade de fazer parte da família LNP. Proporcionando inúmeras oportunidades, ensinando e investindo na minha formação como futura educadora e pesquisadora. A minha co-orientadora JuCa, por não só ter me orientado, mas por ter se tornado uma amiga. Você me apresentou a esse mundo da espectrometria de massas, com paciência e dedicação. Obrigado por cada hora do seu tempo dedicado a mim, não só me ajudando a construir conhecimento, mas compartilhando da vida. A família LNP, onde passei a maior parte dos meus dias nesses últimos dois anos. Sem vocês, eu com toda certeza não chegaria até aqui. Em especial a Giu, cúmplice e parceira desde a graduação, que vem compartilhando comigo risos e lágrimas. Obrigada por cada respirada nos banquinhos do IB, recompondo nossas forças para continuar seguindo em frente. Ao Clube das Bonitas, por estarem nessa caminhada comigo há uns bons anos, partilhando das angústias, crises, sonhos e alegrias. São vocês que fazem com que a vida seja mais leve nas horas difíceis! Aos meus amigos de tatame, que nos dias nublados e escuros estavam lá, não só para trocar socos e chutes, mas para me ajudarem a prosseguir. O Muay Thai trouxe novos maravilhosos amigos, 7kg a menos e o amor da minha vida. Amor, estamos apenas começando. Obrigada por me dar o melhor colo e por me ouvir quando mais precisei. Com vocês amados, divido a alegria desse momento. “Cada um que passa em nossa vida, passa sozinho, pois cada pessoa é única e nenhuma substitui outra. Cada um que passa em nossa vida, passa sozinho, mas não vai só nem nos deixa sós. Leva um pouco de nós mesmos, deixa um pouco de si mesmo. Há os que levam muito, mas não há os que não levam nada. Essa é a maior responsabilidade de nossa vida, e a prova de que duas almas não se encontram ao acaso.” ~ O pequeno príncipe RESUMO A esquizofrenia é um transtorno mental crônico que atinge em média 0,7% da população mundial, sendo seu desenvolvimento relacionado a soma de fatores genéticos e ambientais. Distúrbios cognitivos como atenção, memória e funções executivas são frequentemente observados em pacientes com a doença. Os antipsicóticos consistem na principal forma de tratamento, sendo amplamente utilizados na clínica. No presente projeto foram analisados o proteoma de uma linhagem celular de oligodendrócitos humanos (células MO3.13) tratados com quatro antipsicóticos, sendo dois de primeira-geração (clorpromazina e haloperidol) e dois de segunda-geração (quetiapina e risperidona). Primeiramente, foi estabelecido um protocolo para cultivo das células, publicado como um capítulo de livro. Por conseguinte, a análise dos tratamentos foi realizada através de nano-cromatografia líquida seguida de espectrometria de massas em tandem (nano LC-MS/MS). Posteriormente, as proteínas encontradas com p-value < 0,05 foram submetidas a análise no programa Ingenuity Pathway Analysis (IPA) para obtenção das vias metabólicas relacionadas a cada tratamento. Foram encontradas vias de sinalização em comum e específicas para cada antipsicótico. Os dados gerados nesta dissertação de mestrado auxiliarão na compreensão das vias bioquímicas envolvidas no mecanismo de ação desses medicamentos, que podem orientar o desenvolvimento de novos tratamentos. ABSTRACT Schizophrenia is a chronic mental disorder that affects on average 0.7% of the world population, and its development is related to genetic and environmental factors. Cognitive disorders such as attention, memory and executive functions are often observed in patients with the disease. Antipsychotics consist of the main form of treatment and are widely used in the clinic. In the present project the proteome of a human oligodendrocyte cell line (MO3.13 cells) treated with four antipsychotics, two of the first generation (chlorpromazine and haloperidol) and two of the second generation (quetiapine and risperidone) were analyzed. The analysis of the treatments was performed by liquid nano-chromatography followed by tandem mass spectrometry (nano LC-MS / MS). Subsequently, the proteins found with p- value <0.05 were submitted to analysis in the Ingenuity Pathway Analysis (IPA) program to obtain the metabolic pathways related to each treatment. Canonical pathways were found in common and specific for each antipsychotic. The data generated in this dissertation helped to understand the biochemical pathways involved in the mechanism of action of these drugs, which may guide the development of new treatments.

  • ZNF354C Is a Transcriptional Repressor That Inhibits Endothelial Angiogenic Sprouting James A
    www.nature.com/scientificreports OPEN ZNF354C is a transcriptional repressor that inhibits endothelial angiogenic sprouting James A. Oo1,3, Barnabas Irmer1, Stefan Günther2, Timothy Warwick1, Katalin Pálf1, Judit Izquierdo Ponce1, Tom Teichmann1, Beatrice Pfüger‑Müller1,3, Ralf Gilsbach1,3, Ralf P. Brandes1,3 & Matthias S. Leisegang1,3* Zinc fnger proteins (ZNF) are a large group of transcription factors with diverse functions. We recently discovered that endothelial cells harbour a specifc mechanism to limit the action of ZNF354C, whose function in endothelial cells is unknown. Given that ZNF354C has so far only been studied in bone and tumour, its function was determined in endothelial cells. ZNF354C is expressed in vascular cells and localises to the nucleus and cytoplasm. Overexpression of ZNF354C in human endothelial cells results in a marked inhibition of endothelial sprouting. RNA‑sequencing of human microvascular endothelial cells with and without overexpression of ZNF354C revealed that the protein is a potent transcriptional repressor. ZNF354C contains an active KRAB domain which mediates this suppression as shown by mutagenesis analysis. ZNF354C interacts with dsDNA, TRIM28 and histones, as observed by proximity ligation and immunoprecipitation. Moreover, chromatin immunoprecipitation revealed that the ZNF binds to specifc endothelial‑relevant target‑gene promoters. ZNF354C suppresses these genes as shown by CRISPR/Cas knockout and RNAi. Inhibition of endothelial sprouting by ZNF354C is dependent on the amino acids DV and MLE of the KRAB domain. These results demonstrate that ZNF354C is a repressive transcription factor which acts through a KRAB domain to inhibit endothelial angiogenic sprouting. Te vascular system is controlled by numerous signaling pathways and growth factors which all contribute to the regulation of gene expression.

  • Impaired Immune Surveillance Accelerates Accumulation of Senescent Cells and Aging
    ARTICLE https://doi.org/10.1038/s41467-018-07825-3 OPEN Impaired immune surveillance accelerates accumulation of senescent cells and aging Yossi Ovadya1, Tomer Landsberger2, Hanna Leins3,4, Ezra Vadai1, Hilah Gal1, Anat Biran1, Reut Yosef1, Adi Sagiv1, Amit Agrawal1, Alon Shapira1, Joseph Windheim1, Michael Tsoory5, Reinhold Schirmbeck4, Ido Amit 2, Hartmut Geiger3,6 & Valery Krizhanovsky 1 Cellular senescence is a stress response that imposes stable cell-cycle arrest in damaged 1234567890():,; cells, preventing their propagation in tissues. However, senescent cells accumulate in tissues in advanced age, where they might promote tissue degeneration and malignant transfor- mation. The extent of immune-system involvement in regulating age-related accumulation of senescent cells, and its consequences, are unknown. Here we show that Prf1−/− mice with impaired cell cytotoxicity exhibit both higher senescent-cell tissue burden and chronic inflammation. They suffer from multiple age-related disorders and lower survival. Strikingly, pharmacological elimination of senescent-cells by ABT-737 partially alleviates accelerated aging phenotype in these mice. In LMNA+/G609G progeroid mice, impaired cell cytotoxicity further promotes senescent-cell accumulation and shortens lifespan. ABT-737 administration during the second half of life of these progeroid mice abrogates senescence signature and increases median survival. Our findings shed new light on mechanisms governing senescent- cell presence in aging, and could motivate new strategies for regenerative medicine. 1 Department of Molecular Cell Biology, The Weizmann Institute of Science, 76100 Rehovot, Israel. 2 Department of Immunology, The Weizmann Institute of Science, 76100 Rehovot, Israel. 3 Institute of Molecular Medicine, Stem Cell and Aging, Ulm University, Ulm 89081, Germany.

  • Keratins and Plakin Family Cytolinker Proteins Control the Length Of
    RESEARCH ARTICLE Keratins and plakin family cytolinker proteins control the length of epithelial microridge protrusions Yasuko Inaba*, Vasudha Chauhan, Aaron Paul van Loon, Lamia Saiyara Choudhury, Alvaro Sagasti* Molecular, Cell and Developmental Biology Department and Molecular Biology Institute, University of California, Los Angeles, Los Angeles, United States Abstract Actin filaments and microtubules create diverse cellular protrusions, but intermediate filaments, the strongest and most stable cytoskeletal elements, are not known to directly participate in the formation of protrusions. Here we show that keratin intermediate filaments directly regulate the morphogenesis of microridges, elongated protrusions arranged in elaborate maze-like patterns on the surface of mucosal epithelial cells. We found that microridges on zebrafish skin cells contained both actin and keratin filaments. Keratin filaments stabilized microridges, and overexpressing keratins lengthened them. Envoplakin and periplakin, plakin family cytolinkers that bind F-actin and keratins, localized to microridges, and were required for their morphogenesis. Strikingly, plakin protein levels directly dictate microridge length. An actin-binding domain of periplakin was required to initiate microridge morphogenesis, whereas periplakin-keratin binding was required to elongate microridges. These findings separate microridge morphogenesis into distinct steps, expand our understanding of intermediate filament functions, and identify microridges as protrusions that integrate actin and intermediate filaments. *For correspondence: [email protected] (YI); Introduction [email protected] (AS) Cytoskeletal filaments are scaffolds for membrane protrusions that create a vast diversity of cell shapes.

We utilized an informatics-based approach to develop a transcriptional signature of β-cell GA stress using existing RNA sequencing and microarray datasets generated using human islets from donors with diabetes and islets where type 1(T1D) and type 2 diabetes (T2D) had been modeled ex vivo. To narrow our results to GA-specific genes, we applied a filter set of 1,030 genes accepted as GA associated.
