Enhancing NMDA Receptor Signaling to Treat Fragile X Syndrome

Stephanie Barnes, PhD

Dr. Stephanie Barnes has been investigating the role of NMDA receptors as a FRAXA Postdoctoral Fellow in Dr. Emily Osterweil’s laboratory at the University of Edinburgh from 2016-2018. With an additional year grant from FRAXA, she is now continuing her work to identify novel targets and test pharmacological therapies in the Fragile X mouse model at the Picower Institute at MIT with Dr. Mark Bear.

Finding Fragile X Biomarkers – From Transcriptomics to Behavior in Patients

With this $20,000 award from FRAXA Research Foundation, Dr. Vanderklish and collaborators at Scripps Research Institute, the University of Chile, and the FLENI Institute in Argentina are analyzing patterns in gene expression in blood cells of patients with Fragile X syndrome. They are using “transcriptomics” which can produce a time-sensitive signature of an individual person. This is the first time that all these different levels of study – from transcriptomics to behavior – have been done for individual patients with Fragile X.

Non-Invasive Imaging as a Biomarker for Fragile X Clinical Trials

Andreas Frick and Kamila Castro

FRAXA Research Foundation has renewed Kamila Castro’s 2017 FRAXA Fellowship for a second year. With this $90,000 award, Kamila Castro and Principal Investigator Dr. Andreas Frick are using non-invasive magnetic resonance imaging (MRI) methodology to assess connectivity changes in the brain in Fragile X. If this project is successful, we will have objective outcome measures to evaluate new treatments, both in mice bred to mimic Fragile X and in human patients.

MicroRNA Mediated Astroglial GLT1 Dysregulation in Fragile X

2017 Fragile X Research Grant: MicroRNA Mediated Astroglial GLT1 Dysregulation in Fragile X

Almost all brain research focuses on neurons – nerve cells. However, the brain has many more glial cells which support, nourish, and protect the neurons. FRAXA Research Foundation awarded a 2017 grant $90,000 to support Dr. Yang’s studies of how changes in glial cells contribute to Fragile X syndrome. This grant is funded by a grant from the Pierce Family Fragile X Foundation.

Research Grants to Dr. Kimberly Huber 2000-2010

Kimberly Huber, Ph.D., FRAXA Investigator

With a $474,300 grant from FRAXA Research Foundation from 2000-2013, Dr. Kimberly Huber and her team at the University of Texas conducted several studies on the relationship between mGluR5 and 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.
