4 Countries – 10 Teams – $1 Million
From finding new treatment targets, to pinpointing outcome measures for future clinical trials, to attempting to reactivate the gene which is silenced in Fragile X syndrome, these innovative scientists will bring us closer to a cure.
Improving Clinical Trials
- Many parents of children with Fragile X know well the struggles of getting their children to sleep through the night. Mice and fruit flies engineered to mimic Fragile X Syndrome also have disrupted sleep. Drs. Westmark and Smith will test potential therapeutics in mice using sleep as an outcome measure and investigate whether sleep could be used as an outcome measure for future clinical trials.
- The search is on for a simple blood test to measure how well a treatment works for an individual with Fragile X. Dr. Frank Kooy’s team investigates.
Testing Treatment Targets
- One of the goals of FRAXA’s research program has been to find biological pathways affected in Fragile X that are amenable to treatment with small molecules (drugs). Past efforts have been successful, generating large numbers of treatment targets, and this year, Dr. Osterweil and Dr. Bardoni will study new promising targets.
- All these treatment targets raise an important question: are these various neural pathways and targets related at some key point? Is there a critical node, a point where pathways connect, which would allow for the most efficient treatment? Two projects funded last year are looking for just such critical nodes (see Vanderklish and Moine). Until a critical node is found, we may need combinations of drugs to best help people with Fragile X syndrome. Dr. Razak’s study of combination treatments aims to show us the best way forward and form the basis for success in clinical trials.
Reactivating the Silenced Fragile X Gene
- The holy grail of Fragile X research is to reactivate the gene, FMR1, which is silenced in people who have the syndrome. Using genetic engineering, researchers can already switch on the gene in adult Fragile X mice, and correct symptoms in this way. Teams led by Dr. Peter Todd and Dr. Jeannie Lee will pursue gene reactivation in mice using the new technique, CRISPR.
