Escalating evidence suggests that the impairment of glutathione (GSH)-dependent systems is one of the etiologic factors of schizophrenia. GSH is an important substrate of glutathione peroxidase (GPx). Among GPx isozymes, selenium-dependent GPx (GPx-1) is recognized as a major type, and therefore, this study investigates the role of the GPx-1 gene in abnormal behaviors induced by repeated...
3,4-Methylenedioxymethamphetamine (MDMA) is known to induce dependence and psychosis in humans. Brain-derived neurotrophic factor (BDNF) is involved in the synaptic plasticity and neurotrophy in midbrain dopaminergic neurons. This study aimed to investigate the role of BDNF in MDMA-induced dependence and psychosis. A single dose of MDMA (10mg/kg) induced BDNF mRNA expression in the prefrontal...
Escalating evidence indicates that ginseng treatment protects against psychotoxic behaviors and memory impairment. Although the underlying mechanism of schizophrenia remains elusive, recent investigations proposed that downregulation of glutathione (GSH) can be involved in the pathogenesis of this disorder. Since little is known about the effects of ginseng in a schizophrenia-like animal model,...
