Resumo: | Spiders and scorpions are efficient predators arachnid (PA) consuming preys larger than themselves. Few studies reported, molecularly, the digestion in PA. This work describes a biochemical, transcriptomic and proteomic analysis of the midgut and midgut glands (MMG) and digestive juice (DJ) from Nephilengys cruentata and Tityus serrulatus MMG. Cathepsin L, B, D and F, legumain, trypsin, astacin, carbohydrases and lipases were identified by these approaches. Peptide isomerase and ctenitoxins, which are venom proteins were identified, showing a correlation among digestive and venom enzymes. Summarily, PA relies in multi peptidase system mainly constituted of astacins for extracellular prey liquefaction and cathepsin L for intracellular digestion, describing a molecular model for digestion. Probably, during evolution, gene duplication led a diversification of astacins in the derived groups of Arachnida, like spiders, distinctly from what is observed in basal groups like scorpions. These data on Arachnida digestion will allow detailed multi disciplinary studies. |

Poucos estudos descrevem molecularmente a digestão em AP. Neste trabalho caracterizamos bioquimicamente, por transcriptoma e proteoma o intestino e glândulas digestivas (IGD) e suco digestivo (SD) de Nephilengys cruentata e o IGD de Tityus serrulatus. Catepsinas L, B, D e F, legumaína, tripsinas, astacinas, carboidrases e lipases foram identificadas. Peptídeo isomerase e ctenitoxina foram identificadas no IGD. Estas proteínas podem indicar uma correlação entre enzimas digestivas e do veneno. Portanto, AP apresentam várias peptidases principalmente astacinas para liquefazer a presa extraoralmente e catepsinas L para digestão intracelular, descrevendo um modelo molecular para a digestão. Provavelmente, durante a evolução, eventos duplicação gênica levaram à diversificação das astacinas aracnídeos derivados, como as aranhas, diferentemente dos grupos basais, como os escorpiões. Estes dados sobre a digestão em Arachnida permitirão estudos multidisciplinares.Biblioteca Digitais de Teses e Dissertações da USPRocha, Adriana Rios LopesFuzita, Felipe Jun2014-05-30info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/doctoralThesisapplication/pdfhttp://www.teses.usp.br/teses/disponiveis/87/87131/tde-08122014-100929/reponame:Biblioteca Digital de Teses e Dissertações da USPinstname:Universidade de São Paulo (USP)instacron:USPLiberar o conteúdo para acesso público.info:eu-repo/semantics/openAccesseng2016-12-09T05:00:21Zoai:teses.usp.br:tde-08122014-100929Biblioteca Digital de Teses e Dissertaçõeshttp://www.teses.usp.br/PUBhttp://www.teses.usp.br/cgi-bin/mtd2br.plvirginia@if.usp.br|| atendimento@aguia.usp.br||virginia@if.usp.bropendoar:27212016-12-09T05:00:21Biblioteca Digital de Teses e Dissertações da USP - Universidade de São Paulo (USP)false |
