Recruiting: Metformin Clinical Trial for Ages 16-50 with Fragile X Syndrome

Recruiting: Metformin Clinical Trial for Ages 16-50 with Fragile X Syndrome

FRAXA Research Foundation is funding a clinical trial of metformin for teens and adults with Fragile X syndrome. The trial is being conducted by Dr. Sean McBride at Rowan University in collaboration with colleagues at the University of Pennsylvania. Men and women ages 16-50 with Fragile X syndrome are invited to participate.

Fruit Flies to Model and Test Fragile X Treatments

Fruit Flies to Model and Test Fragile X Treatments

Dr. Jongens and his collaborators have found an insulin-like protein in the fly brain that is overexpressed in the Fragile X mutant fly, leading to increased activity of the insulin signaling pathway. Furthermore, they found that certain behavioral patterns in the Fragile X flies can be rescued by expressing the FX gene just in insulin producing neurons in the fly brain. In the mutant, there are other changes in the signaling pathways, including a decrease in cAMP and elevation in PI3K, mTOR, Akt and ERK activity. They now propose to study 2 medicines used for diabetes: pioglitazone (increases cAMP and decreases Akt and ERK) and metformin (inhibits mTOR), in flies and mice to validate the potential efficacy of these novel therapeutics for Fragile X.
