Methylglyoxal detoxification deficits causes schizophrenia-like behavioral abnormalities

(Tokyo Metropolitan Institute of Medical Science) We generated a mouse model for a subgroup of schizophrenia patients by feeding Glo1 knockout mice VB6-deficent diets (KO/VB6(-)). We found that the KO/VB6(-) mice accumulated methylglyoxal (MG) in the brain and showed schizophrenia-like behavioral impairments. Furthermore, we found aberrant gene expression related to mitochondria function in the prefrontal cortex (PFC) of the KO/VB6(-) mice. Finally, we demonstrated abnormal mitochondrial respiratory function and enhanced oxidative stress in the PFC of KO/VB6(-) mice.
