Abstract

Trehalose, a chemical chaperone and mTOR-independent autophagy enhancer, has shown promise in models of Huntington’s disease, Parkinson’s disease and tauopathies. In this study, two trehalase analogs, lactulose and melibiose, were examined for their potentials in spinocerebellar ataxia treatment. Using a SCA3 ATXN3/Q75-GFP cell model, we found that the ATXN3/Q₇₅ aggregation was significantly prohibited by lactulose and melibiose because of their abilities to up-regulate autophagy. Meanwhile, lactulose and melibiose reduced reactive oxygen species production in ATXN3/Q₇₅ cells. Both of them further inhibited the ATXN3/Q₇₅ aggregation in neuronally differentiated SH-SY5Y cells. These findings suggest the therapeutic applications of novel trehalose analogs in polyglutamine aggregation-associated neurodegenerative diseases.
