Proteotoxicity
WebbLam et al. discover that feeding a vitamin-B12-deficient diet to amyloid beta (Aβ)-expressing C. elegans accelerates paralysis, reduces ATP levels, and increases oxidative stress. Their results indicate that vitamin B12 affects the methionine/SAMe cycle to protect against Aβ-induced proteotoxicity.
