A collaboration we wrote about back in 2017, between Emory cell biology chair Gary Bassell and University of Florida neurogeneticist Eric Wang, is taking off.

The National Institute of Neurological Disorders and Stroke has awarded Bassell’s and Wang’s laboratories $2.2 million over five years to examine the neuronal function of Muscleblind-like proteins, which play key roles in myotonic dystrophy.

The classic symptom for myotonic dystrophy is having trouble releasing one’s grip on a doorknob, but it is a multi-system disorder, caused by expanded DNA triplet or quadruplet repeats. RNA from the expanded repeats is thought to bind and sequester Muscleblind-like proteins, leading to an impaired process of RNA splicing.

Bassell says the project is expected to clarify how Muscleblind-like proteins regulate RNA localization in neurons and also identify therapeutic targets. In recent years, the DM research community has been paying increasing attention to neurologic symptoms.
