OralOme : o contributo dos microrganismos

Abstract

Na saliva humana podem ser encontradas moléculas de diversas fontes: secreções das glândulas salivares major e minor, moléculas de origem plasmática, do fluido crevicular, da mucosa oral e do microbiota oral. Todas estas moléculas interagem e conferem à saliva as suas propriedades. De entre as moléculas existentes, as proteínas desempenham um papel muito importante na definição das propriedades da saliva. A identificação de todas as proteínas presentes na cavidade oral, permitirá definir o proteoma oral humano e a caracterização funcional dessas proteínas nos diversos contextos fisiológicos/patológicos,contribuindo paraa exploração do OralOme Está em desenvolvimento uma ferramenta bioinformática que permite armazenar, integrar e visualizar os dados publicados de proteómica da cavidade oral de forma interpretativa. Esta ferramenta é designada por OralCard, e tem como objectivo contribuir para a clarificação dos mecanismos moleculares da biologia oral humana, para a identificação de marcadores moleculares, úteis no diagnóstico de diversas patologias, orais e sistémicas, e para a identificação de novas moléculas que possam ser alvos terapêuticos. Partindo de uma revisão bibliográfica exaustiva, este estudo tem como objectivo verificar quais as proteínas de origem microbiana experimentalmente determinadas em amostras da cavidade oral, inseri-las na base de dados OralOme,que suporta a ferramenta OralCard,e anotá-las com informação publicada, contribuindo assim para a completa definição do proteoma microbiano da cavidade oral. Foram adicionadas ao OralOme e manualmente anotadas 1212 proteínas de origem microbiana experimentalmente determinadas e publicadas até Abril de 2012.

In human saliva there are different molecules from diverse sources; secretions from major and minor salivary glands, molecules of plasmatic origin, crevicular fluid, oral mucosa and oral microbiome. All of these components interact and give saliva its properties. Of the existing molecules, proteins have a very important role in defining salivas properties. The identification of all the proteins in the oral cavity will allow the definition of the oral proteome and the functional characterization of said proteins in the different physiological/pathological contexts. A tool that allows the storage, integration and visualization of published data on the proteomics of the oral cavity in a comprehensive way is being developed. This tool is called OralCard, and has the objective of contributing to the clarification of molecular mechanisms of human oral biology, identification of molecular markers useful in the diagnosis of several oral and systemic diseases, and identification of new molecules that can act as therapeutic targets. Starting with an extensive bibliographical revision, this study aims to verify which are the experimentally determined microbial proteinsidentified in samples from the oral cavity, insert them in the OralOme data-base supporting OralCard, and annotate them with published information, hence contributing to the complete definition of the microbial proteome of the oral cavity. From the bibliography reviewed up to April 2012, 1212 experimentally determined proteins of microbial origin were identified, manually annotated and added to OralOme.
