Popis: BackgroundProtein O-linked-β-N-acetyl glucosamine (O-GlcNAc) is a post-translational modification to Ser/Thr residues that integrates energy supply with demand. Abnormal O-GlcNAc patterning is evident in several neurological disease states including epilepsy, Alzheimer's disease and autism spectrum disorder (ASD). A potential treatment option for these disorders includes the high-fat, low-carbohydrate, ketogenic diet (KD). The goal of this study was to determine whether the KD induces changes in O-GlcNAc in the BTBRT+tf/j (BTBR) mouse model of ASD.MethodsJuvenile male (5weeks), age-matched C57 or BTBR mice consumed a chow diet (13% kcal fat) or KD (75% kcal fat) for 10-14days. Following these diets, brain (prefrontal cortex) and liver were examined for gene expression levels of key O-GlcNAc mediators, global and protein specific O-GlcNAc as well as indicators of energy status.ResultsThe KD reduced global O-GlcNAc in the livers of all animals (p0.05), yet OGT and OGA expression (mRNA) were elevated in both C57 and BTBR animals (p
