Ketogenic Diet Eases Symptoms in Fragile X Male Mice

The Westmark laboratory continues to study sleep and rest-activity cycles in Fragile X mice as a potential outcome measure that correlates between preclinical and clinical research. The analysis of sleep EEG in the mice has proven more labor intensive than they anticipated, but the team is collaborating with Dr. Rama Maganti’s laboratory at UW-Madison on the development of computer scrips to speed up the analysis.

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.

Auditory Dysfunction in Fragile X Syndrome in a Mouse Model of Fragile X

Auditory Dysfunction in Fragile X Syndrome in a Mouse Model of Fragile X

With a $90,000 grant from FRAXA, Dr. McCullagh and Dr. Achem Klug at the University of Colorado investigated whether auditory neural circuits are altered in Fragile X mice. They saw minor differences in these mice compared to B6 (control) mice in several measures of auditory acuity. Fmr1 mice had increased latency to the startle response for almost all conditions compared to B6 mice, suggesting altered timing to acoustic cues. These experiments show that, consistent with patient reports and anatomical/physiological data, the auditory system is altered in a mouse model of FXS, though with some potential compensation leading to a subtle behavioral impact.

Novel Modulators of Potassium Channels to Treat Fragile X

Novel Modulators of Potassium Channels to Treat Fragile X

With funding from FRAXA over 2015-2017, the Yale University team of Leonard Kaczmarek, PhD showed that the firing patterns of auditory neurons in response to repeated stimulation is severely abnormal in Fragile X mice. Based on these results, they are collaborating with the UK-based company Autifony to develop advanced compounds which may reverse these deficits.

14th Annual Fragile X Poker Run Raises $12,135 for Fragile X Research!

14th Annual Fragile X Poker Run Raises $12,135 for Fragile X Research!

The 14th Annual Fragile X Poker Run was a resounding success. The previous fundraising record of $7,800 was eclipsed by >50%, coming in at $12,135!! This year a very special and moving moment occurred when Amber, who has cerebral palsy, was brought by her parents and positioned in front of the band. She was then serenaded by Mikey through many songs, culminating in Happy Birthday (her 20th). Not a dry eye in the crowd, including Amber and Mikey. Simply magical.

Fragile X Research Impacted by a Small Group of Thoughtful, Committed Citizens

Fragile X Research Impacted by a Small Group of Thoughtful, Committed Citizens

Theirs was an effort by a small group of thoughtful, committed members of the Fragile X Association of Michigan (FXAM) to be sure. The entire project took months! But it was hard work well worth the effort. After writing and revising (and revising), FXAM was awarded a $35,000 grant which the Michigan Fragile X group will now direct to Dr. Todd’s ongoing Fragile X research involving CRISPR!

Kimberly Huber, PhD, Explores Hyperexcitability in Fragile X Syndrome

Kimberly Huber, PhD, Explores Hyperexcitability in Fragile X Syndrome

Ever wonder why your child with Fragile X suddenly screams for no apparent reason or jumps and flaps uncontrollably seemingly for hours? You got it: hyperexcitability. But what exactly causes it? And what can fix it? Kimberly Huber, PhD, is working long and hard in her lab to answer those questions. Dr. Huber, professor, Neuroscience, UT Southwestern Medical Center, is seeking to understand how FMRP regulates connections between brain cells, called synapses, and the function of brain circuits, which are several connected brain cells.

University of Michigan researcher Peter Todd, MD, PhD, Aims to Selectively Turn the Fragile X Gene Back on in Human Cells

University of Michigan researcher Peter Todd, MD, PhD, Aims to Selectively Turn the Fragile X Gene Back on in Human Cells

Fish like salmon are born in fresh water streams and rivers. When the time comes for them to breed, they return to the stream of their birth to lay eggs in the same spot where they were born. To accomplish this, they must swim upstream against the current or flow of the stream. Taking a page out of the salmon DNA playbook, University of Michigan scientists Peter Todd, MD, PhD, and postdoctoral fellow Jill Haenfler, Ph.D., are exploring unchartered waters to find a cure for Fragile X Syndrome. The researchers are adapting CRISPR research to reactivate the FMR1 gene, which provides instructions for making a protein called FMRP — needed for normal brain development.

Meltdown no more? Targeting Hypersensitivity in Fragile X

Meltdown no more? Targeting Hypersensitivity in Fragile X

We’ve all been there. Our child with Fragile X hears something and becomes excited. Very excited. Hand flapping follows with non-stop jumping and ear-piercing squawking. Nothing helps. No meds. No iPhone. No magic toy. Several minutes go by. Sometimes longer. How many times have you apologized in a grocery store — or restaurant — or at the mall? Wouldn’t it make our lives better if this unpredictable excitability was minimalized or eliminated? That’s the premise behind research being conducted at University of California, Riverside. Principal Investigator Khaleel Razak, PhD, and postdoctoral fellow Jonathan W. Lovelace, PhD, are studying mice genetically altered to mimic the genetic characteristics of humans with Fragile X Syndrome.

Fragile X Treatment: New Research Directions

In the wake of negative results from several high-profile clinical trials in Fragile X, we find ourselves questioning many of our previous assumptions about the nature of this disorder. After all, understanding the basic pathology of disease is critical to development of new treatments — this is true across the board, in all branches of medicine.
