目的
2
探讨翻白草总黄酮对2型糖尿病db/db小鼠的血糖、血脂、氧化应激、组织病理及肝脏磷脂酰肌醇-3激酶(PI3K)/蛋白激酶B(Akt)信号通路的影响。
方法
2
24只db/db小鼠随机分为模型组、盐酸二甲双胍组(0.2 g·kg
-1
),翻白草总黄酮低、高剂量组(0.1,0.4 g·kg
-1
),另取6只db/m小鼠作为正常组。药物干预4周后,检测血清中空腹血糖(FBG),糖化血清蛋白(GSP),总胆固醇(TC),甘油三酯(TG),高密度脂蛋白胆固醇(HDL-C),低密度脂蛋白胆固醇(LDL-C),空腹血胰岛素(FINS),丙二醛(MDA)和超氧化物歧化酶(SOD)水平,计算胰岛素抵抗指数(HOMA-IR),检测肝糖原含量;苏木素-伊红(HE)染色观察肝脏、胰腺组织病理学变化;采用蛋白免疫印迹法(Western bolt)分别检测肝脏组织中胰岛素受体
β
(IR
β
),胰岛素受体底物-1(IRS-1),PI3K,磷酸化PI3K(p-PI3K),Akt,p-Akt,葡萄糖转运蛋白4(GLUT4)蛋白的表达。
结果
2
与正常组比较,模型组肝细胞排列紊乱,胞浆内可见大量脂肪空泡、脂滴,伴有部分细胞坏死。胰腺胰岛体积减小,胰岛组织和腺泡细胞界限不明显,细胞排列紊乱,部分细胞空泡化;血清FBG,GSP,TC,TG,LDL-C,FINS,MDA水平显著升高(
P
<
0.01),血清HDL-C,SOD水平明显降低(
P
<
0.05),肝糖原含量显著降低(
P
<
0.01),肝脏组织IR
β
,IRS-1,p-PI3K/PI3K,p-Akt/Akt和GLUT4蛋白表达显著降低(
P
<
0.01)。与模型组比较,翻白草总黄酮低、高剂量组肝细胞形态结构较完整,空泡样变、水肿坏死显著减少。胰腺结构清晰,被膜结构完整,胰岛分布正常,结构完整。血清FBG,GSP,TC,TG,FINS,MDA水平明显降低(
P
<
0.05),血清HDL-C,SOD水平明显升高(
P
<
0.05),肝糖原含量显著升高(
P
<
0.01),肝脏组织IRS-1,p-PI3K/PI3K,p-Akt/Akt和GLUT4蛋白表达明显升高(
P
<
0.05)。
结论
2
翻白草总黄酮可显著改善糖脂代谢紊乱及胰岛素抵抗,抗氧化应激,减轻肝脏、胰腺的病理损伤,提高肝脏组织PI3K/Akt信号通路中的相关蛋白表达,从而防治2型糖尿病。
Objective
2
The hypoglycemic effects and mechanisms of total flavonoids from Potentillae Discoloris Herba(TFE) on insulin resistance through the phosphatidylinositol-3 kinase (PI3K)/protein kinase B (Akt) signaling pathway in db/db mice were investigated.
Method
2
The 24 db/db mice were randomly divided into four groups, model group, metformin group and TFE 100,400 mg·kg
-1
group respectively. The 6 db/m mice as normal control group. After 4 weeks treatment, the mice were processed and the levels of fasting blood glucose(FBG), glycated serum protein(GSP),fasting blood insulin(FINS),triglyceride(TG), total cholesterol(TC), low density lipoprotein cholesterol (LDL-C),high density lipoprotein cholesterol (HDL-C) in serum were detected. Homeostatic model assessments of insulin resistance(HOMA-IR)were quantified. Hematoxylin-eosin(HE)staining of liver and pancreatic tissues were examined. The expression of IR
β
, IRS-1,PI3K,phosphorylation-PI3K (p-PI3K), Akt, phosphorylation-Akt(p-Akt) and glucose transporter 4(GLUT4) in livers were assessed by Western blot.
Result
2
Compared with normal group, model group showed liver and pancreas injury. FBG, GSP, TC, TG, LDL-C, FINS and MDA levels in serum were significantly increased (
P
<
0.01), HDL-C and SOD levels in serum were significantly decreased (
P
<
0.05), liver glycogen content was significantly decreased (
P
<
0.01), as well as expression of IR, IRS-1, p-PI3K/PI3K, p-Akt/Akt and GLUT4 protein in liver tissues were significantly decreased (
P
<
0.01). Compared with model group, TFE was able to relieve liver and pancreas injury,while the levels of FBG, GSP, TC, TG, FINS and MDA in serum were significantly decreased (
P
<
0.05), HDL-C and SOD levels liver were significantly increased (
P
<
0.05), liver glycogen content was significantly increased (
P
<
0.01), and the expressions of IRS-1, p-PI3K/PI3K, p-Akt/Akt and GLUT4 protein in liver tissues were significantly up-regulated (
P
<
0.05).
Conclusion
2
These findings indicate that TFE has the potential to reduce blood sugar and alleviates insulin resistance through the PI3K/Akt signaling pathway in the livers of db/db mice.
