Inhibitors of STEP as a Novel Treatment of Fragile X Syndrome

Inhibitors of STEP as a Novel Treatment of Fragile X Syndrome

With a $349,000 grant from FRAXA Research Foundation from 2008-2015, Dr. Paul Lombroso and his team at Yale University researched if inhibiting STEP could reduce behavioral abnormalities in Fragile X syndrome. Results published.

Preclinical Evaluation of Serotonin Receptor Agonists as Novel Pharmacological Tools in Fragile X Syndrome

Preclinical Evaluation of Serotonin Receptor Agonists as Novel Pharmacological Tools in Fragile X Syndrome

With a $66,000 grant from FRAXA Research Foundation in 2013, Dr. Lucia Ciranna and her team from the Universita di Catania tested if specific serotonins could reverse abnormal phentotypes found in Fragile X syndrome.

Ab-Mediated Translation in Fragile X Syndrome

Ab-Mediated Translation in Fragile X Syndrome

With a $120,000 grant from FRAXA Research Foundation during 2011-2012, Dr. Cara Westmark at the University of Wisconsin explored the role of AbPP as a potential treatment option for fragile X. AbPP produces b-amyloid which is over-expressed in Alzheimer’s disease (AD) and Down syndrome.

Manipulating Basal and mGluR-Stimulated cAMP Level in FXS Model Mice

Manipulating Basal and mGluR-Stimulated cAMP Level in FXS Model Mice

With a $90,000 grant from FRAXA Research Foundation, Dr. Hongbing Wang’s team from Michigan State University looked at a treatment target “downstream” of the mGluR5 called cyclic AMP (cAMP). Levels of cAMP are lower in FXS patients and animal models, suggesting that it plays a role in FXS. Drugs that raise levels of cAMP may effectively treat Fragile X. We are very pleased to report that, in 2012, Dr. Wang received a 5-year, $250,000 per year R01 grant from NIH to continue this promising research.

Understanding the Mechanism of mGluR5 in Fragile X Mouse Models

Understanding the Mechanism of mGluR5 in Fragile X Mouse Models

With $184,000 in funding from FRAXA Research Foundation from 1996-2005, Dr. Ben Oostra and his team at Erasmus University have done multiple studies related to Fragile X syndrome. This lab created the first Fragile X mouse models and went on to perform many critical studies in Fragile X mouse models. Results published.

Developing Fragile X Treatments in Fruit Flies and Mice

Developing Fragile X Treatments in Fruit Flies and Mice

With a $380,000 grant from FRAXA Research Foundation from 2005-2009, Drs. Sean McBride, Tom Jogens, and Catherine Choi studied one of the most important aspects of FRAXA’s research; the preclinical validation of potential therapeutic strategies. Many labs have found new leads for treatment. However, very few have the capacity to test new drugs in the mouse model to establish efficacy rigorously enough to lead to clinical trials. The McBride lab (in a broad collaboration with the Choi, Jongens, and Skoulakis groups) aims to do just that. Results published.

The miRNA Pathway in Fragile X Syndrome

With a $120,000 grant from FRAXA Research Foundation over 2008-2009, Drs. Oostra and deVrij at Erasmus University studied miRNA and Fragile X. miRNAs are RNAs that can repress the translation of target mRNAs – therefore they can play a role in protein synthesis within the neuron. Preliminary results showed large differences in miRNA expression in the Fragile X mouse brain compared to the wild type. This lab investigated the effect of mGluR5 antagonists on the levels of these specific miRNAs.

Role of FMRP Interacting Protein CYFIP1 in Prader-Willi and Fragile X Syndromes

Role of FMRP Interacting Protein CYFIP1 in Prader-Willi and Fragile X Syndromes

With a $105,000 grant from FRAXA Research Foundation from 2005-2006, Dr. Yong-Hui Jiang at Baylor College of Medicine explored the relationship between Fragile X syndrome and Prader-Willi syndrome.

Drosophila CYFIP, a Molecular Link Between Actin Cytoskeleton Remodeling and Fragile X

Drosophila CYFIP, a Molecular Link Between Actin Cytoskeleton Remodeling and Fragile X

With $130,000 in funding from FRAXA Research Foundationfrom 2004-2006, Dr. Angela Giangrande at the Universite Louis Pasteur investigated the interactions between dendrites, messenger mRNA, and the cytoskeleton in fruit flies, which are a simple yet powerful system in which multiple genes can be manipulated with relative ease.

Pharmacologic Interventions in the Fmr1 KO Mouse

Pharmacologic Interventions in the Fmr1 KO Mouse

With $48,600 in grants from FRAXA Research Foundation over 2004-2006, Dr. Catherine Choi at Drexel University studied Fragile X knockout mice to determine future treatment targets for Fragile X syndrome in humans.
