Huntington's disease (HD) is an autosomal dominant, progressive neurodegenerative disease. It occurs due to a mutated huntingtin gene that contains an abnormal expansion of cytosine-adenine-guanine repeats, leading to a variable-length N-terminal polyglutamine (polyQ) chain. The mutation confers toxic functions to mutant huntingtin protein, causing neurodegeneration. Rutin is a flavonoid found in various plants, such as buckwheat, some teas, and apples. Our previous studies have indicated that rutin has protective effects in HD models, but more studies are needed to unravel its effects on protein homeostasis, and to discern the underlying mechanisms. In the present study, we investigated the effects of rutin in a |
