Zelladhäsionsblockade von U937- Zellen an aktivierten HUVEC- Zellen durch hLysII/IV-FucTVI / Celladhesionblockade of U937 -cells on activated HUVEC cells by hLysII/IV-FucTVI

Demmig, Stefanie January 2008 (has links) (PDF)
In CHO-FucTVI- Zellen wurde hLysII/IV stabil transfiziert, mit Puromycin selektioniert und hLysII/IV-FucTVI von den stabil transfizierten CHO-FucTVI- Zelle überexprimiert. Durch Immunaffinitätschromatographie und Ultrafiltration wurde das überexprimierte hLysII/IV-FucTVI aufgereinigt und aufkonzentriert. Durch den Lysozymtest nach Osserman und Lawlor und einen ELISA konnte die Lysozymmenge in den unterschiedlichen Schritten bestimmt werden. Im anschließenden Zelladhäsionsassay konnten bei Konzentrationen von 1 ng/ml, 10 ng/ml und 100 ng/ml hLysII/IV-FucTVI signifikante Reduktionen der Zelladhäsion von U937- Zellen an HUVEC- Zellen festgestellt werden. Die ermittelte mittlere Hemmkonzentration (IC50) von hLysII/IV-FucTVI liegt bei 7*10-12 M. Dies entspricht bei einem Molekulargewicht von 30 kDa der Menge von 0,21 ng/ml und hLysII/IV-FucTVI wäre damit der stärkste bisher bekannte E-Selektin-Antagonist. In dieser Funktion könnte hLysII/IV-FucTVI im Rahmen einer antiinflammatischen oder antineoplastischen Therapie eingesetzt werden. / Stabel transfication of hLysII/IV in CHO-FucTVI- cells and overexprimation. Cleaning and using differents steps to concentrate the overexprimated hLysII/IV-FucTVI. Classified the amount of hLysII/IV-FucTVI and made celladhesionsblockade on activated HUVEC cells with different concetrations of hLysII/IV-FucTVI.The IC50 from hLysII/IV-FucTVI could be difined at 7*10-12.

Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências da Saúde, Programa de Pós-Graduação em Odontologia, Florianópolis, 2017. / Made available in DSpace on 2018-02-13T03:11:34Z (GMT). No. of bitstreams: 1 350204.pdf: 3603572 bytes, checksum: 1c16903aebf743c0cc656f30db39a84f (MD5) Previous issue date: 2017 / Objetivo. A proposta deste estudo foi determinar a melhor evidência disponível sobre o sítio da região buco-maxilo-facial mais acometido por metástases; assim como o tumor primário com maior ocorrência de metástase nestas regiões. Métodos. Foi realizada uma revisão sistemática da literatura considerando somente estudos escritos no alfabeto latino romano e sem restrições de período de publicação. Foram desenvolvidas estratégias de busca para cinco bases de dados: LILACS, LIVIVO, PubMed, Scopus, Web of Science; além de outras duas bases de dados da literatura cinzenta: Google Scholar e ProQuest. O risco de viés foi avaliado utilizando o "Meta-Analysis of Statistics Assessment and Review Instrument? (MASTARI). Os estudos foram selecionados de forma independente, por 2 examinadores, em 2 fases: leitura de resumos e leitura de texto completo. Resultados. A busca nas bases de dados resultou em 3403 artigos. Após a remoção dos duplicados, restaram 1754 artigos fase 1. A leitura dos resumos identificou 64 estudos para fase 2, dos quais 20 foram finalmente incluídos nesta revisão. Foram identificados tumores metastáticos oriundos de tumores primários da mama, próstata, tireoide, intestino, pulmão, rins, esôfago, estômago, pélvis, fígado, cérebro, pâncreas, ovário, laringe, pele, útero, testículos, entre outros. Foi encontrada uma variabilidade nos sítios da cavidade oral afetados, envolvendo onze diferentes regiões anatômicas, além da região maxilomandibular. Dezessete estudos foram classificados como de risco de viés moderado e três como de baixo risco de viés. O sítio da região buco-maxilo-facial mais acometido por metástases foi a mandíbula (54,92%), seguida pelos tecidos moles (40,16%) e maxila (11,69%). Conclusão. Com base nas evidências disponíveis, o tumor primário com maior ocorrência de metástase foi oriundo do pulmão, próstata e seguidos de igual incidência mama, fígado e rins. O sítio mais acometido por metástases foi a mandíbula, seguida pelos tecidos moles e maxila. / Abstract : Objective. The purpose of this study was to determine the best available evidence on the site of the maxillofacial region which is mostly affected by metastases, as well as the primary tumor with a higher occurrence of metastasis in these regions. Methods. A systematic review of the literature was carried out considering only studies written in the Roman Latin alphabet and without any publication period restrictions. Searching strategies were developed for five databases: LILACS, LIVIVO, PubMed, Scopus, Web of Science and also two other gray-related literature databases: Google Scholar and ProQuest?. The risk of bias was evaluated by using the Meta-Analysis of Statistics Assessment and Review Instrument (MASTARI). The studies were selected in an independent manner, by two examiners, in two phases: abstracts? reading and full-texts reading. Results. The database search resulted in 3403 articles. After removing the duplicated ones, 1754 articles remained in phase 1. The abstracts? reading identified 64 studies for phase 2, from which 20 were ultimately included in the present review. Metastatic tumors from primary breast, prostate, thyroid, intestine, lung, kidneys, esophagus, stomach, pelvis, liver, brain, pancreas, ovary, larynx, skin, uterus and testicles tumors, among others, have been identified. The sites affected in the oral cavity widely varied, involving eleven different anatomical regions, besides the maxillary bones. Seventeen studies were classified as having a moderate bias risk and three as having a low risk of bias. The site of the oral cavity and maxillomandibular region which was mostly affected by metastases was the mandible (54.92%), followed by soft tissues (40.16%) and maxila (11.69%). Conclusion. Based on available evidence, the primary tumor with the highest occurrence of metastasis in the oral cavity and maxillary bones was from the lung and the prostate, followed by breast, kidneys and liver. The site mostly affected by metastases was the mandible, followed by soft tissues and maxila.
