Abstract:
Objective To analyze the protective effects ofbutylphthalide(NBP) on apoptosis factors (p-JNK,Fas and FasL) of death receptor pathway in JNK pathway of cell model of Parkinson's disease (PD).Methods SH-SY5Y cell apoptosis model induced by MPP + was established in vitro.The cells were divided into four groups:normal control group,SHSYSY cells were treated with complete medium without drug intervention;MPP+ group,1 mmol·L-1 MPP+ was added into the cells;NBP+ MPP+ group,the cells were pretreated with 10 mol·L-1 NBP for 3 h and added with 1 mmol·L-1 MPP+;SP600125 + MPP+ group,the cells were cultured with 10 mol·L-1 JNK inhibitor SP600125 pretreatment for 3 h and 1 mmol·L-1 MPP+ was added.The proliferative potentiality of SH-SY5Y cells induced by MPP+ was measured by MTT.The apoptotic rate was analyzed by Annexin-V/PI (FCM).The morphology of SH-SY5Y cells was observed by inverted phase contrast microscope.The expression of apoptotic protein p-JNK,Fas,FasL was detected by Western blotting.Results The cell proliferative potentiality in the MPP+ group (49.30 ± 2.07)％ was significantly lower than that of the normal control group (100.00 ±0.00)％ (P ＜ 0.05).The cell proliferative potentiality in NBP + MPP + group and SP600125 + MPP + group were (71.90 ±2.10) ％ and (76.40 ± 2.80) ％,which was significantly higher than that of the MPP + group (P ＜ 0.05).Apoptosis rate in the MPP + group (32.27 ± 2.26) ％ was significantly higher than that of the normal control group (10.63 ± 2.07) ％ (P ＜ 0.05).The apoptosis rate in the NBP + MPP + group and SP600125 + MPP+ group were (21.13 ± 3.63) ％ and (19.15 ± 2.63) ％,and the apoptosis rate was significantly lower than that in the MPP+ group(P ＜0.05).The protein expression levels of p-JNK,Fas and FasL were significandy lower in NBP + MPP+ group and SP600125 + MPP+ group than that in the MPP+ group (P ＜0.05).Conclusion Butylphthalide can protect the injury of SH-SY5Y cells induced by MPP+.The mechanism of butylphthalide inhibiting apoptosis may be achieved through regulating p-JNK,Fas and FasL protein expression of death receptor pathway in JNK pathway and inhibiting the cell apoptosis.
