Interventional Effect and Mechanism of Extract of Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma and Chuanxiong Rhizoma on Vascular Endothelial Cellular Senescence Induced by High Glucose and High Fat
To explore the mechanism of extract of Ginseng Radix et Rhizoma
Notoginseng Radix et Rhizoma and Chuanxiong Rhizoma in delaying the senescence of vascular endothelial cells induced by high glucose and high fat.
Method:
2
The 40 mmol·L
-1
glucose and 100 μmol·L
-1
palmitate were used to induce endothelial cell senescence. The experiment was divided into control group
model group and low
medium and high-dose traditional Chinese medicine groups (50
100
200 mg·L
-1
). The intervention lasted for 48 h. Cell proliferation was detected by cell counting kit-8(CCK-8); cell senescence was detected by senescence
β
-galactosidase staining; p16 and p21 protein expression levels were detected by Western blot; p-H2A.X(Ser139)expression
mitochondria ROS(mtROS) production and changes in mitochondrial membrane potential(MMP) were detected by immunofluorescence.
Result:
2
Compared with the control group
in model group
the cell proliferation ability and the number of SA-
β
-gal blue-stained cells decreased(
P
<
0.01)
while the mtROS production and the expressions of p16
p21 and p-H2A.X(Ser139)increased(
P
<
0.05
P
<
0.01). Compared with the model group
extract of Ginseng Radix et Rhizoma
Notoginseng Radix et Rhizoma and Chuanxiong Rhizoma can increase cell proliferation and MMP levels(
P
<
0.01)
and reduce the number of SA-
β
-gal blue-stained cells
the mtROS production
and expression levels of p16
p21 and p-H2A.X(Ser139)(
P
<
0.05
P
<
0.01).
Conclusion:
2
The above results suggest that extract of Ginseng Radix et Rhizoma
Notoginseng Radix et Rhizoma and Chuanxiong Rhizoma delay of endothelial cellular senescence induced by high glucose and high fat
and its mechanism may be related to increasing mitochondrial membrane potential and reducing DNA damage accumulation caused by ROS production.
