描述 | Parkinson’s disease (PD) is characterized by the selective loss of dopaminergic neurons in the substantia nigra (SN). MPTP is a neurotoxin that can induce symptoms similar to those observed in PD in humans, nonhuman primates, and mice. In addition, MPTP induces selective loss of dopaminergic neurons in mice SN[3]. Mice in the MPTP group were intraperitoneally injected with 20 mg/kg MPTP hydrochloride dissolved in saline, with four injections at 3-hour intervals over a period of 1 day. The number of tyrosine hydroxylase-immunoreactive neurons in the MPTP group was significantly lower than in the normal group (P < 0.05), indicating successful establishment of the Parkinson's disease model. The changes in thioredoxin reductase 1 protein expression in the midbrain 7 days after the last injection of MPTP were detected. The MPTP-treated mice showed a 40% decrease in thioredoxin reductase 1 protein level compared with the normal mice (P < 0.05). Moreover, there was a pronounced reduction in thioredoxin reductase 1 mRNA level in MPTP-treated mice compared with normal mice (P < 0.05)[4]. |
