Studies at Yale University and elsewhere are showing that FMRP plays a significant role in the regulation of potassium channels. Looking forward, potassium channel opener drugs could rescue some symptoms of fragile X in humans.
With a $90,000 grant from FRAXA Research Foundation funded during 2014-2015, Dr. Frank Kooy and colleagues at the University of Antwerp are conducting a double blind crossover trial of ganaxolone in patients with fragile X syndrome. Results of this study were mixed (see Marinus: Results from Phase 2 Exploratory Clinical Study Support Continued Development of Ganaxolone in Fragile X Syndrome.
With a $90,000 grant from the FRAXA Research Foundation, Dr. Robert Wong is investigating how seizures are generated in Fragile X neurons. More generally, he is looking at how synapses are modified to enable learning and memory and how this process is impaired in Fragile X. $90,000 Grant Robert Wong, PhD Principal Investigator State University of New York 2013-2014 FRAXA Research Grant $90,000 over 2 Years Abnormal increases in sensitivity of a type of glutamate receptor (group I mGluR) cause brain malfunction, including epilepsy, in Fragile X syndrome (FXS). We are examining a newly uncovered regulation of this increased group I mGluR sensitivity by a second type of glutamate receptor, the NMDA receptor. By looking at audiogenic seizures in FXS model mice, NMDA receptor blockers were found to robustly suppress these seizures at the young developmental stage. In contrast, the same antagonists activated seizure activities, normally dormant, in adult FXS model mice and in a CGGRead more
With a $50,000 grant from FRAXA Research Foundation from 2002-2003, Dr. Carl Dobkin and his team at the New York Institute for Basic Research studied the causes for heightened seizure activity in fragile X mice. Results published.
