WDR5 is required for DUX4 expression and its pathological effects in FSHD muscular dystrophy

Facioscapulohumeral muscular dystrophy (FSHD) is one of the most prevalent neuromuscular disorders. The disease is linked to copy number reduction and/or epigenetic alterations of the D4Z4 macrosatellite on chromosome 4q35 and associated with aberrant gain of expression of the transcription factor DUX4, which triggers a pro-apoptotic transcriptional program leading to muscle wasting. As today, no cure or therapeutic option is available to FSHD patients. Given its centrality in FSHD, blocking DUX4 expression with small molecule drugs is an attractive option.

Epic Bio, Founded by CRISPR Pioneer, Launches to Revolutionize Genetic Medicine with Epigenetic Engineering

EPIC BIO, a biotechnology company developing ultracompact therapies to modulate gene expression in vivo, today announced its launch and Series A financing of $55 million. Epic was founded by Stanley Qi, Ph.D., a renowned bioengineer and named co-inventor on the CRISPR patent held by the University of California. The company’s mission is to develop a new class of genetic medicines that act on the epigenome, a naturally occurring mechanism that determines which genes are expressed and at what levels.

Using CRISPR to Identify Novel Therapeutic Targets in FSHD

CRISPR-Cas9, originally discovered in prokaryotic organisms to be part of their immune system, has rapidly developed into a gene editing tool far more accurate than its predecessors. This technology is thus generating a lot of buzz due to its potential to correct genetic diseases. However, what if it could be used to identify factors that can lessen disease severity? These targets could be the source of novel treatments. A recent study out in Science Translational Medicine led by Angela Lek PhD and Louis Kunkel PhD explored this in Facioscapulohumeral Muscular Dystrophy (FSHD), a type of muscular dystrophy for which there is no treatment or cure.
