Un subtipo de dicha enfermedad est\u00e1 causado por mutaciones en genes que producen prote\u00ednas responsables de un proceso de maduraci\u00f3n de ARN conocido como \u201c<em>splicing<\/em>\u201d. <b><br \/> Investigadores del grupo de gen\u00e9tica molecular humana del Instituto de Investigaci\u00f3n Biom\u00e9dica de Bellvitge, liderados por Juli\u00e1n Cer\u00f3n, han creado un modelo del gusano <em>C.elegans<\/em> que presenta las alteraciones gen\u00e9ticas hom\u00f3logas a las de la enfermedad en humanos. As\u00ed, este modelo abre una v\u00eda prometedora para entender la patolog\u00eda e investigar nuevas terapias eficientes. <b><br \/> El trabajo, financiado por la Fundaci\u00f3n La Marat\u00f3 de TV3, ha sido publicado en la revista RNA <b><br \/> <b><br \/> Los genes que producen prote\u00ednas de \u201c<em>splicing<\/em>\u201d se expresan en todas las c\u00e9lulas del organismo. Sin embargo, mutaciones en estos genes afectan solo a la retina donde producen la muerte de las c\u00e9lulas, y no a otros tejidos. Se trata de un misterio que aun no se ha resuelto. <b><br \/> El estudio, realizado principalmente por la estudiante de doctorado Karinna Rubio y los doctores Laura Fontrodona y David Aristiz\u00e1bal, combina transcript\u00f3mica, gen\u00e9tica y biolog\u00eda celular para crear un modelo \u00fanico en el que estudiar la Retinosis pigmentaria. <b><br \/> <b><br \/>Los investigadores han observado que inactivando en el gusano <em>C. elegans<\/em> los genes hom\u00f3logos a los causantes de la enfermedad, el animal tambi\u00e9n presenta una muerte celular espec\u00edficamente en un tipo celular del organismo. <b><br \/> Adem\u00e1s, este estudio propone una nueva hip\u00f3tesis, basada en la inestabilidad gen\u00f3mica de las c\u00e9lulas afectadas, para explicar la especificidad de la enfermedad en la retina. <b><br \/> El investigador Juli\u00e1n Cer\u00f3n ha explicado que \u201cactualmente el grupo est\u00e1 trabajando en reproducir en <em>C. elegans<\/em> las mutaciones que existen en pacientes. La gran similitud que presentan estos genes entre humanos y gusanos permitir\u00eda, mediante la t\u00e9cnica de CRISPR, crear animales \u201c<em>avatar<\/em>\u201d con la misma mutaci\u00f3n del paciente. Esto es prometedor ya que <em>C. elegans <\/em>se podr\u00eda convertir en una plataforma sobre la que ensayar f\u00e1rmacos de un modo personalizado\u201d. <b><br \/> <b><br \/> Modeling of autosomal-dominant retinitis pigmentosa in Caenorhabditis elegans uncovers a nexus between global impaired functioning of certain splicing factors and cell type-specific apoptosis.
