Did you know that depression is more common in those with autism and/or Fragile X? Even more disturbing is the discovery that current treatments for depression do not work in Fragile X mice. With this grant, the team will work to develop a rapid screening tool to identify FDA-approved drugs which can treat depression in people with Fragile X syndrome.

Read moreCharacterization of a Novel CYFIP1 – Derived Peptidomimetic Restoring the Dysregulated mRNAs Translation: Toward An Innovative Therapeutic Strategy for FXS

The researchers are developing next-generation drugs called peptidomimetics, using the functional features of FMRP. If they succeed, the hope is that we will have new drugs that could make up for the loss of FMRP, thus treating Fragile X syndrome.
Read moreCannabinoids as a Treatment for Fragile X Syndrome

Many people with Fragile X syndrome are hyper-sensitive to sights and sounds, and Electroencephalography (EEG) studies show that there are abnormalities in brain circuits. EEG studies show similar changes in Fragile X mice. So the team will use EEG tests in mice to find which drugs best reduce hypersensitivity. They can then easily move on to human EEG-based clinical trials. What they learn will tell us much more about why people with Fragile X are hypersensitive – and which drugs could best help them.
Read morePurposeful and FRAXA Partnership Leads to Clinical Trial

Can a combination of drugs make a meaningful difference for people with Fragile X? A new clinical trial is going to find out. 15-20 adult men with Fragile X will be included in this trial to test the effects of an available drug and a nutritional supplement taken together.
Read moreInhibiting Nonsense – Mediated mRNA Decay: A Potential Treatment Approach for Fragile X

All cells have a kind of housecleaning service which sweeps away genetic errors. This is called nonsense-mediated mRNA decay (NMD). With a previous FRAXA grant, this team discovered runaway NMD in cells of Fragile X patients. It’s not yet known how this impacts people with Fragile X. With this grant, Dr. Maquat and Dr. Kurosaki will test drugs which can bring NMD back to normal levels.
Read moreExploring Drug Repurposing to Restore Hippocampal Function in FXS Mouse Models

A gene’s job is to produce a protein. In Fragile X syndrome, the FMR1 gene is mutated and cannot make FMRP, a protein which shapes connections between nerve cells (neurons) in the brain. These connections are the basis of learning and memory. This team has discovered a mechanism involving FMRP that is absolutely essential to control the connections between neurons. These connections are the basis of learning and memory. They will now test available drugs which directly target this mechanism, to see if they can treat Fragile X syndrome.
Read moreContribution of Microglia to the Therapeutic Effects of Metformin and Adiponectin in Fragile X Syndrome

The research team of Brian Christie, PhD and Marie-Eve Tremblay is developing ways to balance hormones, including drugs like metformin and changes in diet, which could not only reduce hunger and obesity, but ultimately also improve learning and behavior in Fragile X syndrome.
Read moreAlternative Splicing in White Blood Cells: A Biomarker for Fragile X Syndrome

Explore groundbreaking research by the University of Massachusetts Medical School and Rush University Medical Center on alternative splicing in white blood cells as a biomarker for Fragile X syndrome, paving the way for personalized treatment optimization through a non-invasive blood test.
Read moreLink Between Lipid Profile, eCBome System and Gut Microbiome in Fragile X Syndrome

Why does obesity challenge so many people with Fragile X? Dr. Caku’s team thinks changes in the gut are the culprit. This team has found that Fragile X syndrome causes changes in the tiny organisms that live in our gut. They believe that these abnormalities cause changes in the brain which impair learning and behavior.
Read moreCharacterization of Microglia Transcriptional Profile in Fmr1 Knockout Mice Model

With this grant, the team will identify the pathways responsible for this excessive activation and attempt to reverse the excess. If they can correct this using drugs, they will be able to identify a new potential treatment for Fragile X syndrome solving one more piece of the Fragile X brain puzzle.
Read moreThe Role of Astrocyte BMP Signaling in Fragile X Syndrome

Astrocytes are star-shaped cells that make up one fifth of all cells in the human brain. Recently researchers found a specific pathway in astrocytes that is overactive in Fragile X syndrome, and they hope to bring this pathway back to normal with a drug. With this grant, the team will try to correct the pathway in Fragile X mice. The hope is that they will find a new potential treatment approach for Fragile X syndrome.

With a $90,000 research grant from FRAXA, Dr. Cara Westmark’s team will use mice to determine if more palatable Atkins-type diets can improve sleep and boost learning skills for those with Fragile X syndrome.
Read moreFRAXA Drug Validation Initiative (FRAXA-DVI)

The FRAXA Drug Validation Initiative (FRAXA-DVI) provides speedy, cost-effective, objective preclinical testing of potential Fragile X treatments. FRAXA-DVI uses in-vitro systems, behavior batteries, and gene expression and peripheral biomarker platforms to validate investigational new drugs and repurposed available compounds in Fragile X syndrome (FXS).

This study will test CBD (cannabidiol) treatment in male and female Fragile X mice to learn how and why it works and whether gender affects responses to CDB treatment. Along with clinical trials, this study will help us to understand and optimize the potential of CBD as a behavior-regulating treatment for Fragile X.
Read moreCellular-Specific Therapeutic Targeting of Inhibitory Circuits in Fragile X Syndrome

Studies have shown that the function of inhibitory networks is disturbed in Fragile X. This abnormality is not well understood but appears to be secondary to abnormalities in metabotropic glutamate and endocannabinoid systems. With a $90,000 grant from FRAXA, Dr. Molly Huntsman’s team examined how these networks interact and how inhibitory deficits can best be remedied.
Read moreAuditory 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.
