Fragile X Syndrome: In Pursuit of a Cure Webinar
Global webinar “Fragile X Syndrome: In Pursuit of a Cure” on July 22, 2021 commemorated World Fragile X Day. Over 5,000 registered from more than 50 countries.
Beneath the Surface of Fragile X Syndrome: Study Sheds Light on What’s Happening in Nerve Cells
This FRAXA-funded project has turned up some surprising results. At first, it might seem Kurosaki and Maquat have found yet another cellular process which is malfunctioning in Fragile X. But this finding is intimately related to previous findings of abnormal protein synthesis and misregulated transcription in Fragile X. FMRP (the protein lacking in Fragile X syndrome) is involved in chaperoning messenger RNAs within cells to active sites, and in controlling their translation into many different proteins. Some of these proteins are transcription factors, which feed back to the nucleus to control gene expression.
Towards Understanding the Role of FMRP in Human Brain Development Using Brain Organoids
Dr. Zhexing Wen and Dr. Peng Jin of the newly funded Fragile X Center of Excellence at Emory University School of Medicine join us in this seminar to present about Understanding the Role of FMRP in Human Brain Development Using Brain Organoids.
Scientists Find a New Way to Reverse Symptoms of Fragile X
FRAXA Investigator and MIT Professor Mark Bear and his colleagues have identified a valuable new target for Fragile X therapeutics: GSK3 alpha. Several FRAXA research teams previously identified GSK3 beta as a treatment target for Fragile X. The catch is that, so far, GSK3 beta inhibitors have proven too toxic for regular use. Dr. Bear’s new discovery opens up the possibility of developing more selective compounds with less toxicity and fewer side effects. Interestingly, lithium inhibits both GSK3 versions – alpha and beta.
Patrick’s PALS 23rd Annual Basketball Tournament Raises $140,000 for Fragile X Research
Patrick’s PALS expanded to 36 teams! The Gray Team topped past champs Kline—winning twice to become Patrick’s PALS XXIII Champions!
Metformin and Aberrant Insulin Signaling in a Fragile X Mouse Model
This 2017-2018 grant of $90,000 is funded jointly by FRAXA and the Fragile X Research Foundation of Canada for the first year. A previous FRAXA grant to the Sonenberg lab has led to great interest in the available drug, metformin, as a potential treatment for Fragile X syndrome. FRAXA is currently organizing clinical trials of metformin.
Takeaways from Fragile X Advocacy Day
At my first Fragile X Advocacy Day, I met with Congress and families, advocating together for research and hope.
Impact of the Fragile X Community
Because of you, FRAXA invests $1M+ each year in Fragile X research and helped launch $35M more in studies leading to clinical trials.
Metformin, Diabetes Drug, Potential Fragile X Treatment
“We treated mice with metformin and corrected all the core Fragile X deficits. We are optimistic about using metformin in human clinical trials. This is a generic drug with few side effects” says Nahum Sonenberg, PhD, James McGill Professor, Department of Biochemistry, McGill Cancer Center, McGill University.
Bryostatin Restores Learning and Memory in Adult Fragile X Mice
A bizarre marine critter found off the California coast — Bugula neritina— is the only known source of a potential new Fragile X treatment, Bryostatin. Last month, FRAXA sat down with scientists from Neurotrope BioScience, a specialty biopharmaceutical company developing medicines for rare diseases and Alzheimer’s based on Bryostatin. Their Fragile X program is based on research by a West Virginia team led by Daniel Alkon, MD, which showed that Bryostatin-1 restores hippocampal synapses and spatial learning and memory in adult Fragile X mice.
Fragile X Syndrome Protein Linked to Breast Cancer Progression
Claudia Bagni (VIB/KU Leuven, Belgium, and the University of Rome, Italy) and colleagues have identified the way Fragile X Mental Retardation Protein or FMRP contributes to the progression of breast cancer. The researchers demonstrated that FMRP acts as a master switch controlling the levels of several proteins involved in different stages of aggressive breast cancer, including the invasion of cancer cells into blood vessels and the spread of these cancer cells to other tissues forming metastasis.
What Works, and What Doesn’t
At the start, it’s always hard to know what methods will work best for something as complex as the development of disease-modifying treatments for Fragile X. But, we’ve always tried to let the science lead us down the right path. At this point, the results are unequivocal, and they have shaped how we are looking for the Next Great Thing in Fragile X treatments.
