The Westmark laboratory continues to study sleep and rest-activity cycles in Fragile X mice as a potential outcome measure that correlates between preclinical and clinical research. The analysis of sleep EEG in the mice has proven more labor intensive than they anticipated, but the team is collaborating with Dr. Rama Maganti’s laboratory at UW-Madison on the development of computer scrips to speed up the analysis.

Drug Repurposing Study Results Accelerate Progress Towards Fragile X Treatments

J. Dora Levin Drug Repurposing • Healx • Research Updates October 29, 2017July 11, 2018autism, FRAXA-DVI, Healx, sleep

While there are over 8,000 rare diseases affecting an estimated 350 million people worldwide, only around 200 of these conditions have effective treatments. Due to the high cost of developing new drugs, rare diseases have historically been less attractive to pharmaceutical companies. Drug repurposing systematically leverages the detailed information available on approved drugs and reduces the time and money needed to deliver safe “new” treatments, but with greater success rates and a potentially more immediate impact on health care.

The 18th International Fragile X and Related Neurodevelopmental Disorders Workshop in Quebec, Canada, was a great success, featuring Fragile X much more heavily than any previous meeting in this series! We asked our speakers to summarize their work in their own words, with brief updates from researchers investigating Fragile X.

Our sons with Fragile X Syndrome typically go to bed early and rise early. Sometimes they jump on us while we are sleeping at 3 a.m., excited to start their day. For heaven’s sake, why? The answer may come from Carolyn Beebe Smith, PhD, senior investigator, Section on Neuroadaptation and Protein Metabolism, National Institute of Mental Health, National Institutes of Health, Bethesda, Maryland. She is studying why children, in particularly boys, with FXS have problems sleeping.

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.

With an $80,000 grant from FRAXA Research Foundation over 2 years, Dr. Ravi Allada and his team studied at Northwestern University sleep behaviors in Fragile X fruit flies. These fruit flies are useful for several important reasons; not only do they have a good cognitive phenotype, they also have a clear disturbance of circadian rhythms. This is an important model for human hyperactivity and sleep disorders, and this group studied the underlying mechanisms in an effort to find treatments for the human conditions.
