ABSTRACT
Objective To study the effects of Yiqi Huayu Jiedu Prescription on the migration ability of MHCC97-H and the expressions of CXCL12, CXCR4 and CXCR7; To discuss its relevant mechanism of action. Methods Setting Sorafenib as a positive control, CCK-8 method was used for determining the effects of Yiqi Huayu Jiedu Prescription on the cell proliferation of MHCC97-H and the optimum concentration. Scratch assay was used to observe the migration ability of MHCC97-H. The protein expressions of CXCL12, CXCR4 and CXCR7 were detected by Western blot after 24 h of medicine intervention. Results Yiqi Huayu Jiedu Prescription and Sorafenib can inhibit the cell proliferation of MHCC97-H , and the inhibitory concentration was 0.095 g/mL and 10 μmol/mL at 24 hours. Yiqi Huayu Jiedu Prescription can inhibit migration ability of MHCC97-H. The protein expressions of CXCL12, CXCR4 and CXCR7 in hepatocellular carcinoma cells decreased after the action of Yiqi Huayu Jiedu Prescription. Conclusion Yiqi Huayu Jiedu Prescription can inhibit MHCC97-H cell proliferation and migration, which may be realized by down-regulating chemokine axis of CXCL12/CXCR4/CXCR7.
ABSTRACT
Objective To observe the influencing of Yiqi Huayu Jiedu Prescription on the growth of HepG2 nude mice transplantation tumor and the expression of related factors of vascular mimicry. Methods Models of transplanted tumors, which were made by HepG2 cells in nude mice, were randomly divided into 7 groups, Yiqi Huayu Jiedu Prescription group, Astragali Radix group, Curcumae Rhizoma group, Paridis Rhizoma group, Gecko group, cis-platinum group, and model group. Except for the model group, the rest groups were given relevant medicine for intervention. 21 days later. HIF-1α, MMP-2, MMP-9, and E-cad were detected by immunohistochemistry, and Twist1 and Bcl-2 were detected by fluorescence quantitative PCR. Results Compared with the model group, tumor volume in the rest groups decreased (P<0.05), and the effect in the Yiqi Huayu Jiedu Prescription group was more obvious than the Astragali Radix group, Paridis Rhizoma group and Gecko group (P<0.05);The expression of vasculogenic mimicry structure was rare in each group, and the model group and cis-platinum group were the most obvious;Except for the Astragali Radix group, the expressions of HIF-1α, MMP-2, and MMP-9 showed statistical significance compared with model group (P<0.05);The expression of E-cad in the Yiqi Huayu Jiedu Prescription group and Astragali Radix group showed statistical significance (P<0.05);The expression of Bcl-2 in the Yiqi Huayu Jiedu prescription group, Paridis Rhizoma group, and Gecko group decreased significantly compared with the model group (P<0.05);The expression of Bcl-2 in the Yiqi Huayu Jiedu prescription group was much better than the other groups (P<0.05);The expression of Twist1 showed statistical significance in the Yiqi Huayu Jiedu Prescription group, Curcumae Rhizoma group, Paridis Rhizoma group, and cis-platinum group (P<0.05). Conclusion Yiqi Huayu Jiedu Prescription can reduce expression of HIF-1α, Twist1, Bcl-2, MMP-2, and MMP-9, and increase expression of E-cad, thereby inhibiting the formation of vascular mimicry.
