目的
2
运用逍遥散加减治疗高催乳素血症(HPRL)模型大鼠,探讨逍遥散加减对HPRL大鼠模型中枢多巴胺转运体(DAT)蛋白激酶C(PKC)依赖信号通路的影响。
方法
2
采用慢性复合应激联合甲氧氯普胺腹腔注射,制作HPRL大鼠模型。将96只大鼠随机分成6组,分别为正常组、模型组、西药组(溴隐亭组,0.001 g·kg
-1
·d
-1
)、逍遥散加减方高、中、低剂量组(分别予以逍遥散加减方60,30,15 g·kg
-1
·d
-1
)。给药14 d后,采用酶联免疫吸附测定法检测血清催乳素(PRL)含量,免疫组化法测定大鼠下丘脑酪氨酸羟化酶(TH)的表达;蛋白免疫印迹法检测大鼠下丘脑多巴胺转运体(DAT),蛋白激酶C(PKC)蛋白的表达。
结果
2
与正常组比较,模型组PRL含量显著升高(
P
<
0.01),TH,PKC的表达显著降低(
P
<
0.01),DAT的表达显著升高(
P
<
0.01);与模型组比较,PRL含量溴隐亭组、逍遥散加减方中剂量组含量显著降低(
P
<
0.01),TH的表达逍遥散加减方高、中剂量组升高(
P
<
0.05,
P
<
0.01),PKC的表达逍遥散加减方中、低剂量组及溴隐亭组显著升高(
P
<
0.01),DAT的表达逍遥散加减方高、中、低剂量组及溴隐亭组均显著降低(
P
<
0.01)。
结论
2
逍遥散加减方可以增加TH的表达,并能通过PKC依赖信号通路下调DAT水平,从而调节催乳素水平。
Objective
2
To investigate the effect of modified Xiaoyaosan on central dopamine transporter (DAT)/protein kinase C (PKC)-dependent signaling pathway in hyperprolactinemia (HPRL) rats.
Method
2
HPRL rat model was established by chronic combined stress combined with intraperitoneal injection of metoclopramide. Ninety-six rats were randomly divided into six groups, namely, the blank group, model group, western medicine (bromocriptine, 0.001 g·kg
-1
·d
-1
) group, and high-, medium-, and low-dose (60, 30, 15 g·kg
-1
·d
-1
) modified Xiaoyaosan groups. After 14 days of administration, the serum prolactin (PRL) content was detected by enzyme-linked immunosorbent assay, the expression of tyrosine hydroxylase (TH) in rat hypothalamus by immunohistochemistry, and the protein expression of DAT and PKC in hypothalamus by Western blot.
Result
2
Compared with the blank group, the model group exhibited significantly increased PRL and DAT (
P
<
0.01), but decreased TH and PKC (
P
<
0.01). Compared with the model group, bromocriptine and modified Xiaoyaosan at the medium dose significantly lowered the content of PRL (
P
<
0.01). The modified Xiaoyaosan at the medium and high doses elevated the expression of TH (
P
<
0.05,
P
<
0.01). The expression levels of PKC in the medium- and low-dose modified Xiaoyaosan groups and the western medicine group were significantly increased (
P
<
0.01), while the DAT expression levels in the high-, medium-, and low-dose modified Xiaoyaosan groups and the western medicine group were decreased (
P
<
0.01).
Conclusion
2
The modified Xiaoyaosan is able to up-regulate the expression of TH and down-regulate the level of DAT through PKC-dependent signaling pathway, thereby regulating the PRL.
