Basic Mechanisms of Disease and Potential Therapeutic Strategies

Basic Mechanisms of Disease and Potential Therapeutic Strategies

With $245,000 in grants from FRAXA Research Foundation, Dr. Stephen Warren and his lab at Emory University studied all aspects of Fragile X syndrome, from the mechanisms of repeat expansion to high-throughput drug screens in the Drosophila model of Fragile X. The Warren lab made the original discovery of the Fragile X gene, FMR1, in collaboration with the Nelson and Oostra labs, and is recognized internationally as a leader in molecular genetics. Recent projects include establishment of induced pluripotent stem cell lines from Fragile X patients, and determination of other forms of mutation in the Fragile X gene, other than the most common trinucleotide repeat expansion.

Using Fenobam to Reduce APP and Abeta in Fragile X Mice

Using Fenobam to Reduce APP and Abeta in Fragile X Mice

With a $130,000 grant from FRAXA Research Foundation over 2008-2008, Drs. James Malter and Cara Westmark at the University of Wisconsin studied the relationship between the Fragile X protein FMRP and APP, a protein important to the pathology of Alzheimer’s Disease. APP may also contribute to the pathology of Fragile X, and its major metabolite, Aß, may contribute to abnormal protein synthesis via a positive feedback loop. This project sought to restore normal dendritic protein synthesis in Fragile X mice by breaking into this loop.

FRAXA Contributes $10,000 to NIH grant to Seaside Therapeutics

FRAXA Contributes $10,000 to NIH grant to Seaside Therapeutics
Randy Carpenter, MD Principal Investigator with Mark Bear, PhD, MIT Co-Investigator (2007)   Clinical development of mGluR5 Antagonists to Treat Fragile X Syndrome and Autism Seaside Therapeutics received a major grant from the NIH, with additional funding from FRAXA and Cure Autism Now (CAN) to develop STX107, a selective mGluR5 antagonist, as a treatment for Fragile X. Unfortunately Seaside has since discontinued development of STX107.Read more
