Low glucose induced Alzheimer's disease‐like biochemical changes in human induced pluripotent stem cell‐derived neurons is due to dysregulated O‐GlcNAcylation

Lowering glucose to a critical level causes AD-like changes in cortical neurons. Defective neuronal structure and function were also recapitulated in current model. Dysregulated O-GlcNAcylation links impaired glucose metabolism to AD-like changes. Mitochondrial abnormalities correlate with O-GlcNAcylation and precede AD-like phenotype. Our model provides a platform to study sAD as a metabolic disease in human neurons.
