Small Molecule Cocktail Can Reactivate the Fragile X Gene in Cells: Progress Report

FRAXA Research Foundation Harvard University • Lee, Jeannie • Massachusetts General Hospital • Research Grant with Results February 20, 2019February 20, 2019iPS, Pierce Family Fragile X Foundation

With a $180,000 grant from FRAXA Research Foundation and the Pierce Family Fragile X Foundation, Dr. Jeannie Lee and her team at Harvard University and Massachusetts General Hospital have run a series of studies aimed at reactivating the gene, FMR1, which is silenced in Fragile X syndrome. Dr. Lee and colleagues have found a method using combinations of specific drugs which can spur the FMR1 gene to produce its normal protein product.

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.

Small Molecule Modulators of Lithium for Treatment of Fragile X Syndrome

FRAXA Research Foundation 2006-2010 Grants • Completed Research Grant • Haggarty, Stephen • Harvard University • Massachusetts Institute of Technology (MIT) • Reis, Surya • Treatment Targets February 1, 2010August 9, 2018autism, GSK3, iPS, lithium

With a $219,500 grant from FRAXA Research Foundation, Dr. Stephen Haggarty from Havard/MIT developed a high-throughput drug screen to find compounds that inhibit GSK3, a critical enzyme in Fragile X. He looked for compounds that can accomplish this either alone or in combination with lithium, offering the possibility of enhancing the effectiveness of lithium as a treatment. His drug screen used patient-specific neural progenitor (NP) cells derived from human induced pluripotent stem cells (iPSCs) – which are created from cells in a skin biopsy from people with Fragile X syndrome (FXS) and other autism spectrum disorders.
