Abstract:
[Abstract] Objective: To investigate the effects of ginsenoside Rg3 on the formation of vasculogenic mimicry (VM) in gastric cancer cell line SGC7901 and its molecular mechanism. Methods: MTT assay was used to detect the effect of different concentrations of Rg3 on the proliferation of SGC7901 cells. SGC7901 cells were grouped as follows: BML-284 group, XAV-939 group, Rg3 group, Rg3+BML-284 group and blank group. Transwell chamber assay was used to detect cell invasion and migration; the formation of VM was observed by tube formation assay; the secretion of MMP-9 and MMP2 was detected by ELISA; the mRNA expressions of GSK-3β and Wnt2B were detected by qPCR; the expression of β-Catenin protein in cells was analyzed by WB; and nuclear entry of β-Catenin was examined by Immunofluorescence. Results: Ginsenoside Rg3 inhibited the proliferation of SGC7901 cells in a time- and concentrationdependent manner; compared with the blank group, 40 mg/L Rg3 significantly inhibited the invasion and migration of SGC7901 cells (both P<0.05) and VM formation (P<0.05); in the meanwhile, the expressions of intracellular GSK-3β, Wnt2B mRNA and β-catenin protein, as well as the nuclear entry of β-catenin were significantly inhibited (all P<0.05). The invasion, migration and VM formation of SGC7901 cells in Rg3+BML-284 group were not significantly different from those in the blank group (all P>0.05). Conclusion: Rg3 can inhibit cell invasion, migration and VM formation in SGC7901 cells by inhibiting the activation of Wnt/β-Catenin pathway.
