目的
2
探讨当归多糖对糖尿病KK-Ay小鼠心肌细胞凋亡的影响。
方法
2
将KK-Ay小鼠随机分为模型组、二甲双胍组(200 mg/kg)和当归多糖高、中、低剂量组(400、200、100 mg/kg),C57BL/6J小鼠作为空白组,每组8只,各组小鼠每日灌胃相应药液或生理盐水1次,连续4周。末次给药后,检测小鼠的空腹血糖、总胆固醇(TC)、低密度脂蛋白胆固醇(LDL-C)、胰岛素(INS)水平,心肌组织中B细胞淋巴瘤2(Bcl-2)、活化的胱天蛋白酶(cleaved-caspase-3)、凋亡信号调节激酶1(ASK1)、磷酸化氨基末端蛋白激酶(p-JNK)、磷酸化需肌醇酶1α(p-IRE1α)蛋白表达以及心肌细胞凋亡情况。
结果
2
与模型组比较,二甲双胍组和当归多糖中、高剂量组小鼠空腹血糖、TC、LDL-C含量和心肌细胞凋亡率以及p-JNK、p-IRE1α、ASK1、cleaved-caspase-3蛋白表达水平均显著降低,INS水平和Bcl-2蛋白表达水平均显著升高(
P
<0.05或
P
<0.01)。
结论
2
当归多糖可改善糖尿病KK-Ay小鼠的血糖和血脂水平,抑制心肌细胞凋亡,其机制可能与抑制IRE1/ASK1/JNK信号通路有关。
OBJECTIVE
2
To investigate the effects of
Angelica sinensis
polysaccharide on the apoptosis of cardiomyocytes in diabetic KK-Ay mice.
METHODS
2
KK-Ay mice were randomly divided into model group, metformin group (200 mg/kg) and
A. sinensis
polysaccharide high-dose, medium-dose and low-dose groups (400, 200 and 100 mg/kg); C57BL/6J mice were included in blank group, with 8 mice in each group. Each group was given relevant medicine intragastrically or normal saline, once a day, for consecutive 4 weeks. After the final administration, the levels of fasting glucose, total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C) and insulin (INS) were detected; the protein expressions of B-cell lymphoma 2 (Bcl-2), cleaved-caspase-3, apoptosis signal-regulated kinase 1 (ASK1), phosphorylated c-Jun
N
-terminal kinase (p-JNK), phosphorylated inositol-requiring enzyme 1α (p-IRE1α) in myocardium, and apoptosis in cardiomyocytes were also detected.
RESULTS
2
Compared with model group, the fasting glucose, TC and LDL-C content, apoptotic rate of cardiomyocyte, protein expressions of p-JNK and p-IRE1α, ASK1, cleaved-caspase-3 were significantly lower in the metformin group and
A. sinensis
polysaccharide medium-dose, high-dose groups; INS level and relative expression of Bcl-2 protein were significantly increased (
P
<0.05 or
P
<0.01).
CONCLUSIONS
2
A. sinensis
polysaccharide can improve the levels of blood glucose and blood lipid and inhibit cardiomyocyte apoptosis in diabetic KK-Ay mice, and the mechanism may be related to the inhibition of IRE1/ASK1/JNK signaling pathway.
