Essa prova de conceito estabelece ainda uma grande plataforma para o tratamento de uma ampla gama de doenças, incluindo a artrite reumatoide e a psoríase" Chad Mirkin, especialista em nanomedicina e coautor do estudo" /><br /><br />Um novo tratamento traz esperanças no combate a um temido tipo de câncer no cérebro, o glioblastoma multiforme. Pesquisadores da Universidade de Northwestern desenvolveram uma terapia que, ao ser testada em ratos, desligou um gene crítico do tumor e, dessa forma, aumentou as chances de sobrevivência dos animais doentes. O trabalho, publicado pela Science Translational Medicine, deve em breve ser testado em humanos.<br /><br />[SAIBAMAIS]O tratamento utilizado pelos cientistas consiste em um pequeno RNA de interferência que envolve uma nanopartícula de ouro com ácidos nucleicos. O conjunto forma uma esfera invisível a olho nu capaz de atravessar a barreira hematoencefálica e chegar ao tumor cerebral. O medicamento aciona o interruptor do gene problemático e consegue silenciá-lo, derrubando as proteínas que mantêm as células cancerosas ativas.<br /><br /><a href="http://publica.correiobraziliense.com.br/app/noticia/#h2href:{%22titulo%22:%22Pagina:%20capa%20ciencia%20e%20saude%22,%22link%22:%22%22,%22pagina%22:%2269%22,%22id_site%22:%2233%22,%22modulo%22:{%22schema%22:%22%22,%22id_pk%22:%22%22,%22icon%22:%22%22,%22id_site%22:%22%22,%22id_treeapp%22:%22%22,%22titulo%22:%22%22,%22id_site_origem%22:%22%22,%22id_tree_origem%22:%22%22},%22rss%22:{%22schema%22:%22%22,%22id_site%22:%22%22},%22opcoes%22:{%22abrir%22:%22_self%22,%22largura%22:%22%22,%22altura%22:%22%22,%22center%22:%22%22,%22scroll%22:%22%22,%22origem%22:%22%22}}">Leia mais notícias em Ciência<br /><br /></a>A matéria completa está disponível <a href="http://publica.correiobraziliense.com.br/app/noticia/#h2href:{%22titulo%22:%22Externo:%20http://impresso.correioweb.com.br/app/noticia/cadernos/saude/2013/10/31/interna_saude,104316/terapia-freia-cancer-no-cerebro-de-ratos.shtml%22,%22link%22:%22http://impresso.correioweb.com.br/app/noticia/cadernos/saude/2013/10/31/interna_saude,104316/terapia-freia-cancer-no-cerebro-de-ratos.shtml%22,%22pagina%22:%22%22,%22id_site%22:%22%22,%22modulo%22:{%22schema%22:%22%22,%22id_pk%22:%22%22,%22icon%22:%22%22,%22id_site%22:%22%22,%22id_treeapp%22:%22%22,%22titulo%22:%22%22,%22id_site_origem%22:%22%22,%22id_tree_origem%22:%22%22},%22rss%22:{%22schema%22:%22%22,%22id_site%22:%22%22},%22opcoes%22:{%22abrir%22:%22_blank%22,%22largura%22:%22%22,%22altura%22:%22%22,%22center%22:%22%22,%22scroll%22:%22%22,%22origem%22:%22%22}}">aqui</a>, para assinantes.
