El papel de p65/RelA en la senescencia celular y la inflamación

Abstract

[Resumen]: El factor de transcripción NF-kβ es una familia de proteínas relacionada con multitud de eventos celulares, entre los que destacan la inflamación, el cáncer y la senescencia celular, por lo que la descripción de los mecanismos de activación y silenciamiento de esta ruta es esencial para el conocimiento acerca de estos procesos. El principal componente de NF-kβ es p65, el cual, es un activador de SASP. Este SASP está estrechamente relacionado con los procesos de la senescencia celular e inflamación, por lo que en este trabajo nos planteamos, mediante un desarrollo experimental basado en estudios moleculares, entender el papel de p65 en dichos procesos mediante su inducción en MSCs y la inhibición del la misma. Además, mediante la inhibición de p65 (usando MG-132, curcumina y JSH-23), no solo hemos podido validar su relación con la senescencia y la inflamación, si no, que la acción de estos inhibidores pone de relevancia su uso como senomórficos, con el fin de influir en futuras terapias celulares asociadas a paliar los efectos de la senescencia celular e inflamación.

[Abstract]: The transcription factor NF-β is a family of proteins related to a multitude of cellular events, including inflammation, cancer and cellular senescence, so the description of the mechanisms of activation and silencing of this pathway is essential for the understanding of these processes. The main component of NF-β is p65, which is an activator of SASP. This SASP is closely related to the processes of cellular senescence and inflammation, so in this work we aimed to know the role of p65 in these processes by means of an experimental development based on molecular studies and its induction in MSCs and its inhibition. Furthermore, by inhibiting p65 (MG-132, curcumin and JSH-23), we have not only been able to validate its relationship with senescence and inflammation, but the action of these inhibitors highlights its use as a senomorphic, in order to influence future cell therapies associated with alleviating the effects of cellular senescence and inflammation.
