To explore the neuroprotective effect of sodium aescinate on rats with Parkinson’s disease by regulating the silent information regulator 1 (SIRT1)/nuclear factor-κB (NF-κB) signaling pathway.
METHODS
2
The Parkinson’s disease rat model was constructed by using 6-hydroxydopamine injection method. Forty-eight rats successfully modeled were randomly divided into model group, sodium aescinate low-dose group (1.8 mg/kg), sodium aescinate high-dose group (3.6 mg/kg), sodium aescinate+EX527 (sodium aescinate 3.6 mg/kg+SIRT1 inhibitor EX527 5 mg/kg) group, with 12 rats in each group. Another 12 healthy rats were selected as the sham operation group. Each group was injected with the corresponding drug solution intraperitoneally, once a day, for 21 consecutive days. Twenty-four hours after the end of the last administration, the motor and cognitive functions of rats were detected, and the morphology of neurons in the substantia nigra and CA1 region of hippocampal tissue were observed. The content of dopamine (DA) in the nigrostriatal and the expression levels of tyrosine hydroxylase (TH) and α-synuclein (α-Syn) in the substantia nigra were detected. The serum levels of pro-inflammatory factor [interleukin-6 (IL-6), IL-18], anti-inflammatory factor (IL-10), and the expression levels of SIRT1, phosphorylated NF-κB p65 (p-NF-κB p65) and NF-κB p65 protein in nigrostriatal were detected.
RESULTS
2
Compared with sham operation group, the neurons in the substantia nigra and CA1 region of hippocampal tissue were seriously damaged in model group; the number of rotations, escape latency, the expression levels of α-Syn in substantia nigra, the levels of serum pro-inflammatory factors, the relative expression ratio of p-NF-κB p65 and NF-κB p65 protein in nigrostriatal were increased or prolonged significantly (
P
<0.05); the target quadrant residence time, the content of DA in nigrostriatal, the expression level of TH in substantia nigra, the serum leve
l of anti-inflammatory factor, and the expression level of SIRT1 protein in substantia nigra striatum were significantly decreased or shortened (
P
<0.05). Compared with model group, the damage degrees of neuron in sodium aescinate groups were alleviated, and the quantitative indicators were significantly improved, which were more significant in the high-dose group (
P
<0.05); EX527 could reverse the improvement effect of high-dose sodium aescinate (
P
<0.05).
CONCLUSIONS
2
Sodium aescinate can inhibit the activation of NF-κB signal by up-regulating the protein expression of SIRT1, thereby reducing the neuroinflammation of rats with Parkinson’s disease, improving the motor and cognitive dysfunctions, and finally playing a neuroprotective role.
