目的
2
探讨益母草碱对生长停滞特异性蛋白6(GAS6)/酪氨酸蛋白激酶受体(Axl)信号通路的影响,阐明其减轻冠心病大鼠心肌损伤的机制。
方法
2
构建冠心病大鼠模型,将造模成功的大鼠按随机抽样方法分为模型组,益母草碱低、高剂量组(分别灌胃25、100 mg/kg益母草碱+腹腔注射75 mg/kg生理盐水),益母草碱高剂量+GAS6/Axl信号通路抑制剂组(灌胃100 mg/kg益母草碱+腹腔注射75 mg/kg的R428),每组12只;另取12只正常大鼠作对照组。各给药组大鼠给予相应药物,对照组和模型组大鼠灌胃并腹腔注射等体积生理盐水,每天1次,连续48 d。给药结束后,检测大鼠心功能和血清中炎症因子及心肌损伤标志物水平;观察其心肌组织病理形态;检测其心肌组织细胞凋亡率和心肌组织中凋亡及GAS6/Axl信号通路相关蛋白表达。
结果
2
与对照组比较,模型组大鼠出现心肌细胞与心肌纤维排列紊乱、心肌细胞肥大、细胞核固缩等病变,左室射血分数、左室短轴缩短率、二尖瓣环舒张早期与舒张晚期运动速度之比及GAS6蛋白相对表达量和B细胞淋巴瘤2/B细胞淋巴瘤2相关X蛋白、磷酸化Axl/Axl比值均显著降低(
P
<0.05),肿瘤坏死因子α、白细胞介素1β、白细胞介素6、肌酸激酶同工酶、肌钙蛋白Ⅰ、肌红蛋白水平以及心肌组织细胞凋亡率和剪切型胱天蛋白酶3/胱天蛋白酶3比值均显著升高(
P
<0.05);益母草碱各剂量组大鼠上述病理情况及各检测指标均显著改善(
P
<0.05),且益母草碱高剂量组效果较益母草碱低剂量组明显(
P
<0.05);R428处理可逆转高剂量益母草碱对冠心病大鼠心肌损伤的改善作用(
P
<0.05)。
结论
2
益母草碱可减轻冠心病大鼠心肌损伤,其作用机制可能与激活GAS6/Axl信号通路相关。
OBJECTIVE
2
To explore the effects of leonurine on growth arrest-specific protein-6 (GAS6)/Axl signaling pathway, and clarify its mechanism of alleviating myocardial injury in rats with coronary heart disease.
METHODS
2
The rat model of coronary heart disease was constructed; successfully modeled rats were randomly separated into model group, leonurine low-dose and high-dose groups (intragastric administration of leonurine 25, 100 mg/kg+intraperitoneal injection of normal saline 75 mg/kg), and leonurine high-dose+GAS6/Axl signaling pathway inhibitor group (intragastric administration of leonurine 100 mg/kg+intraperitoneal injection of R428 75 mg/kg), with 12 rats in each group. Additional 12 normal rats were selected as control group. Each administration group was given relevant medicine; control group and model group were given a constant volume of normal saline intragastrically and intraperitoneally, once a day, for 48 consecutive days. After administration, the heart function of rats, and serum levels of inflammatory factors and myocardial injury markers were detected; the pathological morphology of myocardial tissue was observed; the myocardial cell apoptosis rate, the expressions of apoptosis and GAS6/Axl signaling pathway-related proteins were determined.
RESULTS
2
Compared with control group, model group showed disorders in the arrangement of myocardial cells and myocardial fibers, hypertrophy of myocardial cells, and nuclear condensation; left ventricular ejection fraction, left ventricular fractional shortening, ratio of early-diastolic and late-diastolic motion velocity of the mitral ring, the protein expression of GAS6, B-cell lymphoma 2/B-cell lymphoma 2 associated X protein and phosphorylated Axl/Axl ratios were decreased significantly (
P
<0.05). The levels of tumor necrosis factor-α, interleukin-1β, interleukin-6, creatine kinase isoenzyme, troponin Ⅰ and myoglobin, the cell apoptosis rate, and cleaved caspase-
3/caspase-3 ratio were increased significantly (
P
<0.05). Leonurine could obviously improve the above pathological conditions and detection indicators (
P
<0.05), and the effect of leonurine high-dose group was more significant than that of leonurine low-dose group (
P
<0.05); R428 treatment could reverse the ameliorating effect of high-dose of leonurine on myocardial injury in rats with coronary heart disease (
P
<0.05).
CONCLUSIONS
2
Leonurine can alleviate myocardial injury in rats with coronary heart disease, and its mechanism of action is related to the activation of the GAS6/Axl signaling pathway.
