La desregulaci\u00f3n de los niveles de ARN y prote\u00ednas, en comparaci\u00f3n con los de los tejidos normales, es una caracter\u00edstica molecular constante de todos los c\u00e1nceres. Detr\u00e1s de las causas de estos cambios, recientemente se han identificado modificaciones qu\u00edmicas en las mol\u00e9culas de ARN que afectar\u00edan a su estabilidad, ubicaci\u00f3n o capacidad de producir prote\u00ednas.<\/p>\n
Este es el caso del linfoma de Hodgkin, que constituye aproximadamente un 25-30% de todos los linfomas y que gracias a los constantes avances cient\u00edficos es curable en un 85% de los casos con el tratamiento de primera l\u00ednea. Desgraciadamente, todav\u00eda hay un 15% de pacientes que siguen sin responder a la terapia<\/strong> y tienen una supervivencia muy reducida.<\/p>\n Ahora, en un art\u00edculo publicado en la revista Blood liderado por el Instituto de Investigaci\u00f3n contra la Leucemia Josep Carreras (IJC) y con la participaci\u00f3n de cient\u00edficos del Instituto Catal\u00e1n de Oncolog\u00eda (ICO) y el Instituto de Investigaci\u00f3n Biom\u00e9dica de Bellvitge (IDIBELL), se se\u00f1ala un biomarcador que permitir\u00eda identificar los casos que acabar\u00e1n desarrollando una enfermedad m\u00e1s agresiva y por lo tanto requieren una atenci\u00f3n especial.<\/p>\n \u00abHemos encontrado que ALKBH3 es capaz de regular la actividad del ARN, el paso intermedio entre el genoma y las prote\u00ednas\u00bb, explica la Dra. Anna Sureda<\/strong>, del grupo de Tumores del Sistema Hematopoy\u00e9tico y linfoides<\/a> del IDIBELL y jefa del Servicio de Hematolog\u00eda Cl\u00ednica del ICO. Adem\u00e1s, los resultados indican que esta actividad reguladora es especialmente importante en el linfoma de Hodgkin. \u00abLas c\u00e9lulas cancerosas de este tipo de tumor no expresan el gen ALKBH3, lo que estar\u00eda provocando que tuvieran m\u00e1s capacidad de proliferar y por lo tanto fueran m\u00e1s malignas\u00bb, explica Sureda.<\/p>\n Este descubrimiento abre la puerta a desarrollar tratamientos espec\u00edficos para estos pacientes a trav\u00e9s de la sustituci\u00f3n de la actividad de ALKBH3 o la reactivaci\u00f3n de su expresi\u00f3n. \u00abSin ALKBH3 las c\u00e9lulas cancerosas pueden modificar el microambiente que las rodea y eliminar las barreras para su crecimiento. Por eso es muy importante el desarrollo de buenos modelos tumorales, a partir de los linfomas con esta alteraci\u00f3n, donde poder evaluar nuevas estrategias terap\u00e9uticas\u00bb, concluye el Dr. Alberto Villanueva<\/strong>, jefe del grupo de Resistencia Farmacol\u00f3gica y Xenografts<\/a> del programa ProCURE del IDIBELL y el ICO y colaborador de este estudio.<\/p>\n","protected":false},"excerpt":{"rendered":" La ausencia de ALKBH3 permite a las c\u00e9lulas cancerosas crecer con m\u00e1s libertad y es un indicador de malignidad para este tipo de tumores.
