Spinal and bulbar muscular atrophy (SBMA, also known as Kennedy's disease) is one
of nine neurodegenerative disorders that are caused by expansion of
polyglutamine-encoding CAG repeats. Intracellular accumulation of abnormal
proteins in these diseases, a pathological hallmark, is associated with defects
in protein homeostasis. Enhancement of the cellular proteostasis capacity with
small molecules has therefore emerged as a promising approach to treatment. Here,
we characterize a novel curcumin analog, ASC-JM17, as an activator of central
pathways controlling protein folding, degradation and oxidative stress
resistance. ASC-JM17 acts on Nrf1, Nrf2 and Hsf1 to increase the expression of
proteasome subunits, antioxidant enzymes and molecular chaperones. We show that
ASC-JM17 ameliorates toxicity of the mutant androgen receptor (AR) responsible
for SBMA in cell, fly and mouse models. Knockdown of the Drosophila Nrf1 and Nrf2
ortholog cap 'n' collar isoform-C, but not Hsf1, blocks the protective effect of
ASC-JM17 on mutant AR-induced eye degeneration in flies. Our observations
indicate that activation of the Nrf1/Nrf2 pathway is a viable option for
pharmacological intervention in SBMA and potentially other polyglutamine
diseases.
