Senescencia celular en cáncer y desarrollo

Senescencia celular en cáncer y desarrollo

Abstract

La senescencia celular juega un papel clave en el control del balance celular en diferentes contextos, bloqueando la proliferación y promoviendo la eliminación inmunitaria de células dañadas o no necesarias. Evidencias recientes indican la importancia de senescencia en patologías diversas, como cáncer, fibrosis o diabetes, pero también en procesos fisiológicos como el desarrollo embrionario. Resultados recientes de nuestro grupo han identificado a la homeoproteína SIX1 como un nuevo regulador negativo de senescencia celular. Previamente a esta conexión con senescencia, SIX1 se ha implicado en cáncer y en desarrollo embrionario. Su activación aberrante es frecuente en diversos tumores humanos, mientras que su pérdida de función está asociada a patologías del desarrollo tanto en modelos animales como en humanos. Con estos antecedentes, hemos explorado el papel de la senescencia celular tanto en la actividad oncogénica de SIX1 como en su papel como regulador del desarrollo. Nuestros resultados indican que la acción protumoral de SIX1 está asociada a la represión de senescencia y la activación de plasticidad celular, mientras que los defectos de desarrollo asociados a deficiencias en SIX1 podrían estar debidos a activación aberrante de senescencia. Mediante el estudio de la conexión de SIX1 con senescencia, nuestros resultados subrayan la relevancia de la senescencia celular en contextos tan diversos como el cáncer y el desarrollo embrionario.
