ha sido muy emocionante encontrar las condiciones en paralelo en gusanos y peces d\u00f3nde este nuevo CRISPR-Cas9 funcionara tan bien<\/em>\u201d.<\/p>\n <\/p>\n
Condiciones para su funcionamiento en animales<\/h3>\n
La modificaci\u00f3n del dominio de reconocimiento del ADN de este nuevo sistema mejorado de CRISPR-Cas9 fue ideado y ejecutado por expertos en estructura de prote\u00ednas del laboratorio de Ben Kleinstiver en Boston, que tambi\u00e9n ha participado en el estudio. Hasta la fecha, esta nueva herramienta hab\u00eda mostrado eficacia en l\u00edneas celulares y plantas, pero no se hab\u00eda conseguido aplicar en la edici\u00f3n del genoma de animales.<\/p>\n
En este trabajo, los laboratorios del Dr. Cer\u00f3n en IDIBELL y del Dr. Moreno-Mateo en CABD unieron fuerzas para hacer funcionar esta t\u00e9cnica en animales. A pesar de que en un inicio el nuevo CRISPR-Cas9 parec\u00eda no ser \u00fatil para el genoma animal, los investigadores lograron hacerlo funcionar incrementando la concentraci\u00f3n hasta seis veces.<\/p>\n
\u201cAunque no lo sabemos con certeza, es posible que la necesidad de incrementar la concentraci\u00f3n sea debida a que este nuevo sistema tiene m\u00e1s potenciales dianas de acci\u00f3n y<\/em>, por lo tanto, necesite m\u00e1s prote\u00ednas Cas que busquen el sitio adecuado<\/em> -comenta el Dr. Cer\u00f3n<\/strong>-. A\u00fan as\u00ed, y a pesar de la elevada concentraci\u00f3n, demostramos que es igual de especifico que el anterior<\/em>\u201d.<\/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":"Esta nueva herramienta de CRISPR-Cas9 es capaz de modificar regiones de genes hasta ahora inaccesibles, expandiendo enormemente las posibilidades de la edici\u00f3n gen\u00e9tica y de medicina de precisi\u00f3n.<\/p>\n","protected":false},"author":8,"featured_media":20622,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"site-sidebar-layout":"default","site-content-layout":"default","ast-site-content-layout":"","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","theme-transparent-header-meta":"default","adv-header-id-meta":"","stick-header-meta":"default","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[186,298,297],"tags":[],"class_list":["post-20621","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-area-medicina-traslacional","category-modelos-de-enfermedad-en-c-elegans-programa-de-genes-enfermedad-y-terapia","category-programa-de-genes-enfermedad-y-terapia"],"publishpress_future_action":{"enabled":false,"date":"2025-01-29 05:33:20","action":"change-status","newStatus":"draft","terms":[],"taxonomy":"category"},"publishpress_future_workflow_manual_trigger":{"enabledWorkflows":[]},"_links":{"self":[{"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/posts\/20621","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/users\/8"}],"replies":[{"embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/comments?post=20621"}],"version-history":[{"count":2,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/posts\/20621\/revisions"}],"predecessor-version":[{"id":20624,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/posts\/20621\/revisions\/20624"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/media\/20622"}],"wp:attachment":[{"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/media?parent=20621"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/categories?post=20621"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/idibell.cat\/es\/wp-json\/wp\/v2\/tags?post=20621"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
