Objective
2
To observe the effect of Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma, and Chuanxiong Rhizoma extract (GNC) on mitochondrial oxidative stress in hydrogen peroxide (H
2
O
2
)-induced aging of human umbilical vein endothelial cells (HUVECs), and explore the therapeutic mechanism of GNC on aging HUVECs.
Method
2
The HUVECs were classified into the control group (control), H
2
O
2
model group (H
2
O
2
), H
2
O
2
+ DMSO group (DMSO, 1 mL·L
-1
), resveratrol group (Resv, 8 μmol·L
-1
), and low- (200 mg·L
-1
), medium- (300 mg·L
-1
), and high-dose (400 mg·L
-1
) GNC (GNC-L, GNC-M, and GNC-H) groups. Except control group and H
2
O
2
group, the other groups were intervened with corresponding agents. Subsequently, 300 μmol·L
-1
H
2
O
2
was given to other groups except the control group for 4 h to induce aging, and then the cells were cultured in normal media for 24 h. The aging degree, cell cycle, and mitochondrial reactive oxygen species (mtROS) level were determined by SA-
β
-galactosidase (SA-
β
-Gal) staining, flow cytometry, and MitoSox red fluorescence staining, respectively. JC-10 was used as a fluorescent probe to detect the changes in mitochondrial membrane potential, and Western blot was performed to detect the expression of manganese superoxide dismutase (MnSOD) and p-p66 proteins.
Result
2
The SA-
β
-gal staining results showed that H
2
O
2
group had increased blue-stained cells compared with other groups (
P
<
0.01). Compared with those in the control group, the ratio of G
0
/G
1
phase cells significantly increased (
P
<
0.05) and that of G
2
/M phase cells decreased (
P
<
0.05) in the H
2
O
2
group. Compared with those in the H
2
O
2
group, the proportion of G
0
/G
1
cells decreased (
P
<
0.05) while that of G
2
/M cells increased (
P
<
0.05) in GNC-H groups and Resv group. The fluorescence staining for determining mitochondrial ROS level showed that the H
2
O
2
group had weakened fluorescence intensity than the control, GNC-H, and GNC-M groups (
P
<
0.05). The mitochondrial membrane potential fluorescence intensity of the H
2
O
2
group was weaker than that of the control, GNC-H, GNC-M, and GNC-L groups (
P
<
0.01), as well as the Resv group (
P
<
0.05). Western blot showed that the protein level of MnSOD was significantly lower in the H
2
O
2
group than in the control, GNS-H, and GNS-M groups (
P
<
0.05), whereas the protein level of p-p66 showed an opposite trend (
P
<
0.01), indicating that the medication can alleviate the intracellular mitochondrial oxidative stress.
Conclusion
2
GNC can delay the H
2
O
2
-induced aging of vascular endothelial cells. The GNC intervention significantly regulated the mitochondrial ROS, mitochondrial membrane potential, and related proteins MnSOD and p-p66 to alleviate oxidative stress. Chinese medicinal materials may delay the aging of vascular endothelial cells by inhibiting mitochondrial oxidative stress.
