Abstract:
Objective: To investigate the effect and the possible mechanism of Rhizoma Paridis total saponin (RPTS) on human gastric cancer cell line MKN-45 proliferation, migration and invasion in vitro. Methods: MKN-45 cells were cultured in vitro and treated respectively with indicated concentrations of RPTS (2.5, 5.0, 10.0, 20.0, and 40.0 μg/mL) for 24 h, and cell viability of cell proliferation was detected by MTT assay; The invasive and metastatic ability of MKN-45 treated with indicated concentrations of RPTS (2.5, 5.0, 10.0 μg/mL) was detected by Transwell migration assay and wound healing assay; Elisa assay was employed to detect the concentrations of MMP-9 induced by LiCl after RPTS administration (10, 20, and 40 μg/mL) in the cell supernatant; Western blotting and qRT-PCR were respectively performed to investigate the invasion and migration related protein and mRNA level of VEGF, COX-2, and GSK-3β in RPTS-treated MKN-45 after LiCl stimulation for 24 h. Results: Compared with the control group, RPTS (10, 20, and 40 μg/mL) significantly inhibited the proliferation of MKN-45 cells (P < 0.05 and P < 0.001); RPTS (2.5, 5.0, 10.0 μg/mL) suppressed the invasion and migration of MKN-45 cells (P < 0.05 and P < 0.001); Compared with the model group, RPTS significantly downregulated the expression of MMP-9 in the cell supernatant of MKN-45 cells induced by LiCl (P < 0.05 and P < 0.01), and RPTS also decreased the protein and mRNA expression level of VEGF and COX-2, but it significantly upregulated the expression of GSK-3β at the protein and mRNA level (P < 0.05 and P < 0.001). Conclusion: RPTS play a pivotal role in suppressing the invasion and migration of MKN-45 cells in vitro, and its mechanism may be related to the regulating effects of the Wnt/β-catenin pathway in the human gastric adenocarcinoma cell.
