compartiment d’inactivaci\u00f3 de Lamin A\/C<\/strong> es redueix en gran manera, el que altera la localitzaci\u00f3 i inactivaci\u00f3 de la perif\u00e8ria del cromosoma X. Les observacions indiquen una relocalitzaci\u00f3 general del cromosoma X “inactivat” a regions m\u00e9s actives del nucli, el que es correlaciona amb la major expressi\u00f3 g\u00e8nica d’aquests cromosomes en c\u00e8l\u00b7lules envellides.<\/p>\nLa desregulaci\u00f3 de la inactivaci\u00f3 del cromosoma X est\u00e0 fortament associada a la s\u00edndrome mielodispl\u00e0stica<\/strong>, un grup de c\u00e0ncers que afecta amb m\u00e9s freq\u00fc\u00e8ncia a la gent gran, en el qual les c\u00e8l\u00b7lules sangu\u00ednies no maduren. Per tant, l’exist\u00e8ncia d’una alteraci\u00f3 dependent de l’edat de la inactivaci\u00f3 del cromosoma X pot tenir implicacions importants per a comprendre la fisiologia de l’hematopoesi durant l’envelliment i la patog\u00e8nesi de les neopl\u00e0sies hematopo\u00e8tiques relacionades amb l’edat.<\/p>\n <\/p>\n

L\u2019Institut d’Investigaci\u00f3 Biom\u00e8dica de Bellvitge (IDIBELL) \u00e9s un centre de recerca en biomedicina creat l\u2019any 2004. Est\u00e0 participat per l’Hospital Universitari de Bellvitge i l\u2019Hospital de Viladecans de l’Institut Catal\u00e0 de la Salut, l’Institut Catal\u00e0 d’Oncologia, la Universitat de Barcelona i l\u2019Ajuntament de l\u2019Hospitalet de Llobregat.<\/em><\/p>\nL\u2019IDIBELL \u00e9s membre del Campus d’Excel\u00b7l\u00e8ncia Internacional de la Universitat de Barcelona HUBc i forma part de la instituci\u00f3 CERCA de la Generalitat de Catalunya. L’any 2009 es va convertir en un dels cinc primers centres d\u2019investigaci\u00f3 espanyols acreditats com a institut d\u2019investigaci\u00f3 sanit\u00e0ria per l\u2019Instituto de Salud Carlos III. A m\u00e9s, forma part del programa \u201cHR Excellence in Research\u201d de la Uni\u00f3 Europea i \u00e9s membre de EATRIS i REGIC. Des de l\u2019any 2018, l\u2019IDIBELL \u00e9s un Centro Acreditado de la Fundaci\u00f3n Cient\u00edfica AECC (FCAECC).<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"Per equilibrar l’expressi\u00f3 g\u00e8nica entre les femelles XX i mascles XY s’inactiva un dels cromosomes X de la femella.
