Fragile X Fruit Fly Research Bears Fruit

April 26, 2016

A new FRAXA-funded study shows how the hormone insulin – usually associated with diabetes — is involved in the daily activity patterns and learning deficits in the fruit fly model of Fragile X Syndrome (FXS). The study also reveal a metabolic pathway that can be targeted by new and already approved drugs to treat Fragile X patients, notably metformin.
