In a study involving fruit flies, John Tower, a professor of biological sciences at USC Dornsife, compared the effects of mifepristone to rapamycin, a drug that has demonstrated the ability to increase the lifespan of various animals.

The study, published in the journal Fly, showed that both drugs independently extended the lifespan of fruit flies.

Interestingly, combining the two drugs does not offer additional benefits and a slightly reduced lifespan, suggesting they act through the same biological pathway.
