Identificación y caracterización funcional de genes diana de la oncoproteína EWSR1::FLI1 característica de los sarcomas de Ewing
Los sarcomas de Ewing son un tipo de tumores de la infancia y la adolescencia que se caracterizan por la presencia de translocaciones cromosómicas que dan lugar a factores de transcripción quiméricos. La más frecuente de estas alteraciones cromosómicas fusiona el gen EWSR1 con el gen FLI1, dando lugar al factor de transcripción aberrante EWSR1::FLI1. EWSR1::FLI1 desempeña un papel fundamental en el desarrollo del sarcoma de Ewing, ya que regula la expresión de centenares de genes implicados en el proceso tumoral. En nuestro laboratorio combinamos el uso de tecnologías shRNA y CRISPR/Cas9 para generar modelos de enfermedad con las técnicas más avanzadas de análisis genómico y proteómico para identificar los genes implicados en el desarrollo del sarcoma de Ewing. El objetivo final es identificar genes diana que permitan el desarrollo y diseño de terapias dirigidas más eficaces y con menos efectos secundarios.
Desarrollo de terapias avanzadas para el tratamiento del sarcoma de Ewing
El tratamiento estandar del sarcoma de Ewing se basa en el uso de quimioterapia, radioterapia y cirugía. Aunque estos tratamientos son relativamente eficaces para algunos tumores localizados, son totalmente ineficientes en el caso de pacientes con tumores metastásicos o resistentes a los tratamientos convencionales. Como consecuencia de la falta de alternativas terapéuticas eficaces, tres de cada cuatro niños o adolescentes con tumores metastásicos o refractarios morirán por causa de la enfermedad. Es por tanto urgente desarrollar nuevas terapias para dar respuesta a este grupo de pacientes. En nuestro laboratorio estamos trabajando en el desarrollo de terapias disruptivas, que representen un enfoque totalmente novedoso para el tratamiento de esta enfermedad. Nuestra apuesta se basa en el uso de aproximaciones de terapia génica y el uso de vectores virales (principalmente adenovirus) y no virales (principalmente nanopartículas lipídicas) para vehiculizar las terapias a las células tumorales.
