Sus experimentos se han realizado con moscas del vinagre y han observado que reducir la actividad de la vía de señalización del factor de crecimiento similar a la insulina/insulina (IIS) en el tejido graso de moscas adultas incrementa en más de un 50% el tiempo de vida.
Otras investigaciones anteriores han comprobado que lo mismo sucede en el gusano C. elegans y en ratones, pero no se comprendía bien el proceso celular que conduce a este aumento de la longevidad.
Los resultados del presente estudio muestran que el sistema que gobierna la longevidad en esas especies es el mismo que en seres humanos.
