Gene therapy with AR isoform 2 rescues SBMA phenotype by modulating AR transcriptional activity

Atrophy phenotype by modulating AR transcriptional activity AR-silencing strategies have shown encouraging results in preclinical models but are hampered by the risks of long-term, widespread AR loss. Alternatively, small molecules that modulate AR coregulator–binding affinity are an attractive therapeutic avenue. Nevertheless, the lack of full understanding of their mechanisms of action, potential off-target effects, and unfavorable pharmacokinetic profiles limits their clinical applicability. In our study, we establish a physiological role of one of the naturally occurring AR isoforms, i.e., AR isoform 2 (AR-2), in fine-tuning full-length AR transcriptional activity. Furthermore, by selectively targeting mutant AR transcriptional dysregulation, we provide proof-of-principle evidence for efficacy and safety of a gene therapy strategy based on delivery of this AR variant to treat SBMA, confirming the translational potential of this strategy.
