Connectivity as a Biomarker for Future Fragile X Clinical Trials

Connectivity as a Biomarker for Future Fragile X Clinical Trials

With a 2017 grant from FRAXA Research Foundation of $90,000, Dr. Andreas Frick’s team at Neurocentre Magendie, in France, will test non-invasive imaging using magnetic resonance imaging (MRI) as a potential biomarker for future fragile X syndrome clinical trials.

Fragile X Syndrome Drug Validation Initiative (FRAX-DVI)

Fragile X Syndrome Drug Validation Initiative (FRAX-DVI)

The FRAXA Drug Validation Initiative (FRAX-DVI) provides speedy, cost-effective, objective testing of potential new fragile X treatments. FRAXA has funded FRAX-DVI for $50,000 in 2017.

Defining the Subcellular Specificity of Metabotropic Glutamate Receptor (mGluR5) Antagonists

Defining the Subcellular Specificity of Metabotropic Glutamate Receptor (mGluR5) Antagonists

With $217,500 in grants from FRAXA Research Foundation, Dr. Karen O’Malley and team studied the function of mGluR5 when it is inside cells. Many of the symptoms of fragile X Syndrome (FXS) are thought to arise due to overactive metabotropic glutamate receptor 5 (mGluR5) signaling, which is normally opposed by the protein missing in FXS, Fragile X Protein (FMRP).

Biomarker Discovery and Validation for Fragile X Syndrome

With a $60,000 grant from FRAXA Research Foundation in 2015 that was renewed in 2016, Dr. Eric Klann of New York University will research biomarkers in fraile X syndrome and how to translate these markers from mouse models to human patients.

Fragile X Mutant Mouse Facility

Fragile X Mutant Mouse Facility

With $375,000 in grants from the FRAXA Research Foundation since 2009, Dr. David Nelson has developed an impressive array of advanced mouse models of fragile X, at Baylor College of Medicine. These models are available to investigators worldwide on request. This resource has been essential for a broad, rapid distribution of fragile X and related gene mouse models and has increased the pace of fragile X research.

Functional Interplay Between FMRP and CDK5 Signaling

Functional Interplay Between FMRP and CDK5 Signaling

With a $180,000 grant from the FRAXA Research Foundation over 2011-2014, Dr. Yue Feng and Dr. Wenqi Li at Emory University will study CDK5 pathway function and regulation in an effort to break down whether and how CDK5 signaling is affected by the loss of the fragile X protein, FMRP, in the fragile X mouse model.

Small Rho GTPases, a Potential Therapeutic Target for Fragile X Syndrome

Small Rho GTPases, a Potential Therapeutic Target for Fragile X Syndrome

With $384,345 in grants from FRAXA Research Foundation, Dr. MariVi Tejada from the University of Houston focused on a particularly promising point of intervention in pathways of brain receptors, and tested several potential therapeutic compounds in an attempt to rescue function in the mouse model of fragile X.

Evaluation of CamKII Dependent Regulation of mGluR5-Homer Scaffolds as a Potential Therapeutic for Fragile X Syndrome

Evaluation of CamKII Dependent Regulation of mGluR5-Homer Scaffolds as a Potential Therapeutic for Fragile X Syndrome

Dr. Huber made the original discovery of the mGluR Theory of Fragile X when she was a postdoctoral fellow in the lab of Dr. Mark Bear, with her first FRAXA grant in 2000. Dr. Huber has received $474,300 in grants from FRAXA Research Foundation since then, researching molecular mechanisms and developmental switches in fragile X syndrome. She has worked with 4 FRAXA Postdoctoral Fellows (Elena Nosyreva, PhD in 2006; Jennifer Roseni, PhD in 2007; Tong Zang, PhD in 2010-2011; and Weirui Guo, PhD in 2012-2013) and has received supporting funds from The Meadows Foundation of/for Texas.

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.
