Transcriptional Signatures Sensitive to Cognition-Improving Pharmacological Treatments in Fragile X Syndrome

Transcriptional Signatures Sensitive to Cognition-Improving Pharmacological Treatments in Fragile X Syndrome

The Fragile X field needs biomarkers to accurately measure the effects of potential treatments in both Fragile X mice and in humans. Dr. Ozaita and his team have found molecular features in the brain that can serve as an objective signature for the syndrome. They will use this tool to test cannabidiol and two other drugs in mice.

Compound that Inhibits mGluR5 Corrects Signs of Fragile X in Adult Mice

A study finds that a new compound reverses many of the major symptoms associated with Fragile X syndrome (FXS). The paper is published in the April 12 issue of the journal Neuron, describing the exciting observation that the FXS correction can occur in adult mice, after the symptoms of the condition have already been established. Previous research has suggested that inhibition of mGlu5, a subtype of receptor for the excitatory neurotransmitter glutamate, may ameliorate many of the major symptoms of the disease. This study, a collaboration between a group at Roche in Switzerland, led by Dr. Lothar Lindemann, and Dr. Mark Bear’s MIT lab, used an mGlu5 inhibitor called CTEP to examine whether inhibition of mGlu5 could reverse FXS symptoms.

Results Reported: Using EEG Responses to Sound for Fragile X Drug Discovery

Results Reported: Using EEG Responses to Sound for Fragile X Drug Discovery

Jonathan Lovelace, a FRAXA funded Postdoc at UC Riverside, has made some exciting EEG findings over the past few years studying auditory hypersensitivity in mice and therapeutic drug treatments. A big obstacle in FXS research has been establishing reliable, unbiased, and translation relevant biomarkers that can be used to determine the effectiveness of therapies. One of the most important discoveries they have made is the striking similarity in EEG biomarkers between mice and humans.

Combinatorial Drug Treatment in a Model of Fragile X Syndrome using Novel Biomarkers

With a $90,000 grant from FRAXA Research Foundation awarded over 2016-2017, University of California researchers Khaleel Razak, PhD, and Jonathan W. Lovelace, PhD, are exploring drug combinations to limit hypersensitivity to sounds in Fragile X mice.

Fragile X Syndrome Research & Treatment • FRAXA Research Foundation – Finding a Cure for Fragile X

FRAXA Research Foundation’s mission is to find effective treatments and ultimately a cure for Fragile X syndrome. Fragile X syndrome is the most common inherited cause of autism and intellectual disabilities. We directly fund research grants and fellowships at top universities around the world. We partner with biomedical and pharmaceutical companies, large and small, to bridge the gap between research discoveries and actual treatments.
