Atualidades proteômicas na sepse

Abstract: The increased knowledge regarding proteomic analysis techniques has allowed for better understanding of the molecular bases related to the identification of cell signaling, modifying protein, and post-translational modification pathways, in addition to the characterization of specific biological markers. Thus, documenting certain proteins expressed in sepsis is a promising approach to elucidate pathophysiological, diagnostic, therapeutic, and prognostic aspects in this condition with a purpose of applying them… Show more

“…(5-7,9) Thus, the biological approach to the interaction between P. falciparum and Homo sapiens sapiens might support the development of new models of scientific research, providing a beneficial opportunity for further understanding this infectious condition. (10,11) Therefore, proteomic analysis - a methodology that aims to outline the functional units of a cell, its proteins, and its complex network of interactions and signaling pathways in a given underlying disease and in a physiological condition (12) - has the potential to clarify the pathophysiological, diagnostic, prophylactic, and therapeutic aspects of infectious diseases, (13) including severe malaria. (14,15) The improvement of proteomic studies could elucidate the molecular mechanisms involved in the development of the disease, allowing (1) the identification of changes in the expression of proteins related to intracellular and intercellular signaling pathways, (2) the development of biomarkers for early diagnosis and prognostic prediction, and (3) the establishment of new therapies.…”

“…8,20 A técnica baseia-se na aplicação de potencial elétrico sobre o gel, onde na primeira dimensão ocorre a focalização isoelétrica-separando as proteínas de acordo com os seus pontos isoelétricos (pI)-enquanto na segunda dimensão a separação ocorre por meio das massas moleculares. 7,9 Depois de isolar as proteínas, estas podem ser identificadas de maneira intacta ou por shotgun, utilizando MS ou cromatografia líquida acoplada à espectrometria de massas (LC-MS). Contudo 2D-PAGE é uma técnica trabalhosa, demorada, dispendiosa e com sérias limitações intrínsecas.…”

“…Contudo 2D-PAGE é uma técnica trabalhosa, demorada, dispendiosa e com sérias limitações intrínsecas. 8,7,20 A análise completa do proteoma em um único gel é extremamente difícil, devido as diferentes concentrações das proteínas, o que geralmente ocasiona a perda de resolução por supressão das proteínas menos abundantes. 4,9,15,17 Por se tratar de macromoléculas com características químicas diferentes, sejam, básicas, ácidas, hidrofóbicas, hidrofílicas, diferentes grupos funcionais e tamanhos; a solubilização completa das proteínas retidas no gel em um único detergente ou mistura destes (SDS e CHAPS, por exemplo) não é eficiente, resultando em perda de analito e baixa sensibilidade na detecção por MS. 2,8,4 Outro inconveniente é o número de etapas que a análise se submete, pois é necessário recortar cada ponto que contém a proteína no gel antes da aplicação em MS, o que aumenta a manipulação da amostra e dificulta a automatização da técnica.…”
