compartimento de inactivaci\u00f3n de Lamin A\/C<\/strong> se reduce en gran medida, lo que altera la localizaci\u00f3n e inactivaci\u00f3n de la periferia del cromosoma X. Las observaciones indican una relocalizaci\u00f3n general del cromosoma X \u00abinactivado\u00bb a regiones m\u00e1s activas del n\u00facleo, lo que se correlaciona con la mayor expresi\u00f3n g\u00e9nica de estos cromosomas en c\u00e9lulas envejecidas.<\/p>\nLa desregulaci\u00f3n de la inactivaci\u00f3n del cromosoma X est\u00e1 fuertemente asociada al s\u00edndrome mielodispl\u00e1sico<\/strong>, un grupo de c\u00e1nceres que afecta con mayor frecuencia a las personas mayores, en el que las c\u00e9lulas sangu\u00edneas no maduran. Por lo tanto, la existencia de una alteraci\u00f3n dependiente de la edad de la inactivaci\u00f3n del cromosoma X puede tener implicaciones importantes para comprender la fisiolog\u00eda de la hematopoyesis durante el envejecimiento y la patog\u00e9nesis de las neoplasias hematopoy\u00e9ticas relacionadas con la edad.<\/p>\n <\/p>\n

El Instituto de Investigaci\u00f3n Biom\u00e9dica de Bellvitge (IDIBELL) es un centro de investigaci\u00f3n en biomedicina creado en 2004. Est\u00e1 participado por el Hospital Universitario de Bellvitge y el Hospital de Viladecans del Instituto Catal\u00e1n de la Salud, el Instituto Catal\u00e1n de Oncolog\u00eda, la Universidad de Barcelona y el Ayuntamiento de L’Hospitalet de Llobregat.<\/em><\/p>\nEl IDIBELL es miembro del Campus de Excelencia Internacional de la Universidad de Barcelona HUBc y forma parte de la instituci\u00f3n CERCA de la Generalitat de Catalunya. En 2009 se convirti\u00f3 en uno de los cinco primeros centros de investigaci\u00f3n espa\u00f1oles acreditados como instituto de investigaci\u00f3n sanitaria por el Instituto de Salud Carlos III. Adem\u00e1s, forma parte del programa \u00abHR Excellence in Research\u00bb de la Uni\u00f3n Europea y es miembro de EATRIS y REGIC. Desde el a\u00f1o 2018, IDIBELL es un Centro Acreditado de la Fundaci\u00f3n Cient\u00edfica AECC (FCAECC).<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"Para equilibrar la expresi\u00f3n g\u00e9nica entre las hembras XX y machos XY, se inactiva uno de los cromosomas X de la hembra.
