In neurodegenerative diseases (ND), FOXO factors such as DAF‐16 and FOXO3 may protect against the cytotoxicity of Huntingtin (HTT) (Parker et al., 2012; Tourette et al., 2014), SOD1 and p150Glued (Mojsilovic‐Petrovic et al., 2009), α‐synuclein (Pino et al., 2014), and Aß (Cohen et al., 2009). This evidence concerns the gene FOXO3 and Norrie disease.
