Understanding RAN Proteins in Huntington's Disease and Spinocebellar Ataxias

Contribution of RAN proteins to HD, SCA3 other CAG.CTG expansion diseases

NIH-funded research University of Florida · NIH-11144595

This research explores how certain proteins, called RAN proteins, contribute to conditions like Huntington's disease and various spinocerebellar ataxias, with the goal of finding new ways to help patients.

What this research studies

Our team discovered RAN proteins in 2011, and since then, we've learned that these proteins build up in people with nine different expansion disorders, including Huntington's disease and spinocerebellar ataxia. We are now working to understand if these RAN proteins are harmful and if we can reduce their levels to lessen disease symptoms. We are developing new tools, including gene therapy (AAV) and small molecule approaches, to block the production of these RAN proteins. Our hope is that by targeting these proteins, we can find new treatments for these challenging conditions.

Who could benefit from this research

Good fit: This foundational research is relevant to individuals living with Huntington's disease, spinocerebellar ataxia type 3 (SCA3), and other related CAG·CTG expansion disorders.

Not a fit: Patients whose conditions are not related to CAG·CTG repeat expansion disorders or RAN protein accumulation would likely not directly benefit from this specific research.

Why it matters

Potential benefit: If successful, this research could lead to new treatments that reduce harmful RAN proteins, potentially slowing or stopping the progression of Huntington's disease and various spinocerebellar ataxias.

How similar studies have performed: Our team and others have previously shown that RAN proteins accumulate in disease-relevant human tissues, building a foundation for this current approach to target them.
