Dr. Casanovas<\/strong>.<\/p>\nUna vez confirmada la heterogeneidad de respuesta hab\u00eda que identificar las se\u00f1ales moleculares que la determinan, y que por tanto, que permitir\u00edan escoger los pacientes que resultar\u00edan beneficiados con el tratamiento. El estudio ha utilizado diversas herramientas bioinform\u00e1ticas de an\u00e1lisis gen\u00e9ticos y moleculares que han puesto en evidencia la implicaci\u00f3n de una v\u00eda de se\u00f1alizaci\u00f3n celular, concretamente del gen ALDH1A3, en la respuesta divergente frente a la terapia antiangiog\u00e9nica.<\/p>\n
El Dr. Oriol Casanovas<\/strong> apunta que \u00aben este estudio hemos identificado un nuevo biomarcador<\/strong> capaz de predecir si un paciente puede beneficiarse m\u00e1s del tratamiento con antiangiog\u00e9nicos<\/em>\u00ab, y a\u00f1ade, \u00abestos hallazgos pueden abrir la puerta a nuevas dianas y estrategias terap\u00e9uticas dirigidas a suprimir la malignidad de estos tratamientos<\/em>\u00ab.<\/p>\n <\/p>\n
Las herramientas del estudio<\/h3>\n
<\/p>\n
Para estudiar el comportamiento de los tumores frente al tratamiento con antiangiog\u00e9nicos, y determinar la variaci\u00f3n interpacient existente, los investigadores crearon una bater\u00eda de modelos ortotr\u00f3picos de rat\u00f3n<\/strong>. Estos modelos consisten en la implantaci\u00f3n de biopsias de tumores renales de pacientes en el mismo tejido de rat\u00f3n, lo que permite reproducir la variabilidad entre pacientes e identificar los aspectos clave de la evoluci\u00f3n tumoral. Se trata de una herramienta precl\u00ednica con mucho potencial.<\/p>\nEl estudio de los genes expresados por tumores renales tras el tratamiento con antiangiog\u00e9nicos, y su correlaci\u00f3n con la respuesta tumoral posterior, ha permitido identificar el biomarcador que puede discriminar entre tumores invasivos y no-invasivos.<\/p>\n","protected":false},"excerpt":{"rendered":"
