Finding Fragile X Biomarkers – From Transcriptomics to Behavior in Patients

FRAXA Research Foundation 2018 Grants • Biomarkers • Carullo, Paulina • Cogram, Patricia • Current Research Grants • Scripps Research Institute • Vanderklish, Peter November 6, 2018January 3, 2019EEG, FRAXA-DVI, mRNAs

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.

She is working with principal investigator, Dr. Charles Nelson, Professor of Pediatrics at Harvard Medical School and a specialist in cognitive neuroscience. Co-funded by the Autism Science Foundation and the Pierce Family Fragile X Foundation.

In Their Own Words: Reports From the International Fragile X Workshop

The 18th International Fragile X and Related Neurodevelopmental Disorders Workshop in Quebec, Canada, was a great success, featuring Fragile X much more heavily than any previous meeting in this series! We asked our speakers to summarize their work in their own words. These brief updates from researchers investigating Fragile X.

Brain Imbalance Target of Dr. Erickson’s New Clinical Trial

Theodore Coutilish Biomarkers • Cincinnati Children's Hospital • Clinical • Erickson, Craig • Research Updates October 25, 2017June 15, 2018Abilify, AstraZeneca, autism, AZD7325, EEG, GABA, glutamate

According to Dr. Erickson, AZD7325 is a drug that selectively boosts GABA neurotransmission in the brain. GABA is the primary neurochemical in the brain that blocks brain activation. GABA activity is in balance in the brain with Glutamate activity, which is the primary neurochemical that causes brain activation. In Fragile X, GABA activity is insufficient and glutamate activity is excessive, likely causing brain activity to be out of balance. AZD7325 attempts to correct parts of this imbalance by boosting the insufficient GABA activity in the brains of people with Fragile X

Combinatorial Drug Treatment in a Model of Fragile X Syndrome using Novel Biomarkers

Once the neural marker is identified for a particular challenge, such as kids with poor language versus good language, neural markers can be measured during drug and behavioral therapy trials to see if a child is improving based on objective biological measures.

Kimberly Huber, PhD, Explores Hyperexcitability in Fragile X Syndrome

Sensory Overload 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. Her current focus is the study of synapses and brain circuits in the mouse that mediate sensory perception, including perception of touch and sound. She aims to understand the cellular and molecular mechanisms by which loss of FMRP causes hyperexcitable sensory circuits. The goal: to develop targeted therapeutics that can restore normal brain function and reduce sensory hypersensitivity. “Sensory brain circuits are overactive, or hyperexcitable,Read more
