Objective:
2
To investigate the potential mechanism of astragaloside Ⅳ in protecting liver injury and phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt)/forkheadbox transcription factor 1 (FoxO1)
phosphoenolpyruvate carboxykinase (PEPCK) and glucose 6-phosphatase (G6Pase) protein expressions in type 2 diabetic (T2DM) rats.
Method:
2
After 6 weeks of high-sugar and high-fat diet
a model of type 2 diabetes was established through intraperitoneal injection of streptozotocin (STZ
0.035 g·kg
-1
). The rats were randomly divided into normal group
model group
low
medium and high-dose astragaloside Ⅳ groups and metformin group

metformin were administered in the low
middle and high-dose astragaloside Ⅳ and metformin groups. After 8 weeks of continuous administration
and 24 hours later after the last gavage
the rats were executed. Serum and liver tissues were collected to detect serum liver biochemical indexes
liver index HDL-C. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of liver tissue. Masson staining was used to observe the degree of liver fibrosis. The changes of glycogen
glycoprotein
or mucopolysaccharide in tissue cells were observed by periodic acid Schiff (PAS) reaction staining. Immunohistochemistry and Western blot analysis were used to detect the expression levels of PI3K/Akt/FoxO1 signaling protein and PEPCK and G6Pase in liver tissues of each group.
Result:
2
Compared with normal group
the liver index of the model group increased significantly (
P
<
0.01)
the levels of liver function indicators alanine aminotransferase(ALT)
aspartate aminotransferase(AST)
TC and TG were significantly increased (
P
<
0.01)
while HDL-C and body weight were significantly reduced (
P
<
0.01). The results of immunohistochemistry and Western blot showed that the signal of PI3K/Akt/FoxO1 was weakened (
P
<
0.01)
and PEPCK and G6Pase were increased (
P
<
0.01) in model group. Compared with model group
the contents of ALT
AST
TC and TG in middle and high-dose astragaloside Ⅳ groups were significantly decreased (
P
<
0.05
P
<
0.01)
while the body weight was significantly increased (
P
<
0.05
P
<
0.01)
the middle and high dose of astragaloside Ⅳ significantly inhibited the levels of FoxO1
PEPCK and G6Pase in liver tissue (
P
<
0.05
P
<
0.01)
and enhanced the phosphorylation of FoxO1 (
P
<
0.05
P
<
0.01).
Conclusion:
2
Astragaloside Ⅳ may inhibit T2DM hepatic gluconeogenesis by regulating PI3K/Akt/FoxO1 signaling pathway
and inhibiting high-fat
high-sugar and low-dose STZ
thereby protecting liver damage in T2DM rats.
