,GRh
2
)对结肠癌耐药细胞HCT116/L-OHP迁移、侵袭的影响,并探讨其作用机制。
方法:
2
细胞计数试剂盒(cell counting kit-8,CCK-8)法检测不同质量浓度GRh
2
(0,2.5,5,10,20,40 mg·L
-1
)对HCT116/L-OHP细胞增殖抑制作用;划痕实验,Transwell实验及黏附实验分别检测GRh
2
(0,2.5,5,10 mg·L
-1
)对细胞迁移、侵袭及黏附能力的影响;蛋白免疫印迹法(Western blot)检测GRh
2
(0,5,10,20,30 mg·L
-1
)对HCT116/L-OHP细胞上皮型钙黏蛋白(E-cadherin)和基质金属蛋白酶-9(matrix metalloproteinase-9,MMP-9)蛋白表达水平的影响。
结果:
2
与空白组比较,GRh
2
(5,10,20,40 mg·L
-1
)可显著抑制HCT116/L-OHP耐药细胞的增殖能力(
P
<
0.05,
P
<
0.01),并且呈浓度依赖性;与空白组比较,GRh
2
组(5,10 mg·L
-1
)划痕愈合率明显减小(
P
<
0.05,
P
<
0.01),GRh
2
组穿过小室的细胞数量明显减少(
P
<
0.05,
P
<
0.01),细胞的迁移和侵袭能力受到显著抑制,并且呈浓度依赖性;GRh
2
组黏附细胞数量显著减少(
P
<
0.05,
P
<
0.01),细胞的黏附能力受到显著抑制,并且呈浓度依赖性;与空白组比较,GRh
2
(10,20,30 mg·L
-1
)促进了E-cadherin的蛋白表达(
P
<
0.05,
P
<
0.01),同时抑制了MMP-9蛋白表达(
P
<
0.01),呈一定的浓度依赖性。
结论:
2
GRh
2
可显著抑制结肠癌耐药细胞HCT116/L-OHP的侵袭和迁移能力,其潜在机制可能与促进E-cadherin并抑制MMP-9的表达有关。
Objective:
2
To observe effect of ginsenoside Rh
2
(GRh
2
) on the invasion and migration of colon cancer resistant cells HCT116/L-OHP and its specific mechanism.
Method:
2
Cell counting kit-8 (CCK-8) assay was used to detect the inhibitory effect of different concentrations of GRh
2
(0
2.5
5
10
20
40 mg·L
-1
) on HCT116/L-OHP cell proliferation
scratch assay
Transwell assay and adhesion assay were used to detect the effects of GRh
2
(0
2.5
5
10 mg·L
-1
) on cell migration
invasion and adhesion. The protein expression levels of E-cadherin and matrix metalloproteinase-9(MMP-9) were examined by Western blot.
Result:
2
Compared with control group
GRh
2
(5
10
20
40 mg·L
-1
) significantly inhibited the proliferation of HCT116/L-OHP cells in a dose-dependent manner(
P
<
0.05
P
<
0.01); Compared with the control group
the scratch healing rate of GRh
2
group (5
10 mg·L
-1
) was significantly decreased (
P
<
0.05
P
<
0.01)
the number of cells passing through the chamber of GRh
2
group was significantly decreased (
P
<
0.05
P
<
0.01)
cell migration and invasive ability were significantly inhibited in a dose-dependent manner. The number of adherent cells in GRh
2
group was significantly reduced (
P
<
0.05
P
<
0.01)
and the cell adhesion ability was significantly inhibited. Compared with the control group
GRh
2
(10
20
30 mg·L
-1
) promoted E-cadherin protein expression (
P
<
0.05
P
<
0.01)
while protein expression of MMP-9 was inhibited (
P
<
0.01).
Conclusion:
2
GRh
2
can significantly inhibit the invasion and migration of HCT116/L-OHP in colon cancer cells
and its potential mechanism may be related to the promotion of E-cadherin and the inhibition of MMP-9 expression in a dose-dependent manner.
