What this research studies

As someone living with SBMA, this project uses your cells to make muscle cells in the lab so researchers can see how energy is lost in SBMA. Scientists will turn patient blood or skin cells into stem cells, correct the AR mutation in some cells with CRISPR to create matched controls, and grow them into skeletal muscle tissue. They will measure metabolism and NAD+ levels, study the role of the enzyme CD38 in breaking down NAD+, and test whether lowering CD38 restores muscle energy. The work combines patient-derived cells, metabolomics, and prior mouse data to point toward treatments that could move into human testing.

Who could benefit from this research

Good fit: Ideal candidates are adult men diagnosed with SBMA (androgen receptor polyglutamine expansion), especially those willing to donate blood or skin samples for lab studies.

Not a fit: People without SBMA, including most women without symptoms or people with other neuromuscular disorders, are unlikely to receive direct benefit from this project.

Why it matters

Potential benefit: If successful, this could point to new treatments that restore muscle energy and reduce fatigue in men with SBMA.

How similar studies have performed: Preclinical work in mice and other disorders shows that restoring NAD+ can improve muscle and nerve function, but targeting CD38 in SBMA is a newer approach with mostly laboratory-stage evidence.
