Descripció general
El propòsit del nostre laboratori en l'estudi de la regulació gènica guiada per ARN es va centrar en la funció dels ARN no codificants petits i llargs que guien nous esdeveniments nuclears. Estem realitzant una anàlisi detallada dels processos d'ARN nuclear mitjançant l'estudi de la identitat, la localització i les funcions de molècules específiques d'ARN nuclear, complexos d'ARN/proteïnes nuclears i processos de transport nuclear en Arabidopsis thaliana i Caenorhabditis elegans. Mitjançant aquestes anàlisis, esperem caracteritzar noves vies de l'ARN nuclear i descobrir la seva rellevància biològica.
