Effect of Erzhiwan on Invasion and Metastasis of Human Colon Cancer Cells
To investigate the effect of Erzhiwan (EZW) on the invasion and metastasis of human colon cancer HCT116 cells.
Method:
2
The abilities of invasion (number of transmembrane cells) and migration (relative width of 48 h scratch) were observed by Transwell assay. Western blot was used to detect vascular endothelial growth factor (VEGF) and E-cadherin protein
respectively.
Result:
2
① Transwell results showed that compared with the blank control group
the number of model piercing cells in each drug group was decreased (
P
<
0.05)
and the number of perforating model cells was the least after combined use of L-OHP. ②Scratch test results showed that compared with the blank control group
the migration of HCT116 cells was inhibited in each treatment group (
P
<
0.05). The inhibitory rate of high-dose EZW group was higher than that of L-OHP group at 12 h (
P
<
0.05)
and the inhibition rate of EZW in other time groups was lower than that of L-OHP group (
P
<
0.05). The inhibition rate of combined treatment group was higher than that of EZW groups (
P
<
0.05). The figure of combined group was higher than that of L-OHP group at 12 h (
P
<
0.05)
and combined group was lower than L-OHP group at 48 h (
P
<
0.05). ③ Western blot results showed that compared with the control group
the expressions of VEGF protein in 10% and 20%EZW group were significantly decreased (
P
<
0.05)
and the expression of VEGF protein in 5.19 mg·L
-1
L-OHP combined with 10% EZW group was lower than that in L-OHP group (
P
<
0.05). Compared with the blank control group
EZW groups decreased the expression of E-cadherin protein (
P
<
0.05). And 5.19 mg·L
-1
L-OHP combined with 10% EZW group and L-OHP group increased the expression of E-cadherin protein significantly. Compared with L-OHP group
the expression of E-cadherin protein was the highest (
P
<
0.05).
Conclusion:
2
EZW can inhibit the invasion and metastasis of colon cancer HCT116 cells
and the best effect is achieved after combined with L-OHP. This may be related to the decrease of VEGF protein expression and the increase of E-cadherin protein expression after combination with L-OHP.
