ABSTRACT
The purpose of this study was to investigate the inhibitory effect of the main 9,10-dihydrophenanthrene orchinol isolated from Spiranthes sinensis Radix et Herba on the invasion and migration of human gastric cancer SGC-7901 cells and its preliminary molecular mechanism. SGC-7901 cells were cultured in vitro, after the cells were treated with different final concentrations(5, 10, 20, 40, 80 µmol·L⻹) of orchinol for 24, 48 or 72 hours, the effect of orchinol on cell viability was measured by MTT assay. Wound healing and Transwell assays were performed to determine the effects of different final concentrations(5, 10, 20, 40 µmol·L⻹) of orchinol for 48 hour on invasion and migration abilities of SGC-7901 cells, respectively. The protein expression levels of ß-catenin, Wnt-3α, DvL2, cyclinD1 and GSK-3ß were detected by Western blot. The results showed that 5-80 µmol·L⻹ orchinol inhibited the viability of SGC-7901 cells in a dose-dependent and time-dependent manner, and the IC58 values of 24, 48 and 72 hours were 77.79, 42.96 and 7.85 µmol·L⻹, respectively. Compared with the control group, the ability of invasion and migration of SGC-7901 cells was significantly inhibited after treated with 5, 10 and 20 µmol·L⻹ orchinol for 48 hours (P<0.05, P<0.01), and the dose-effect relationship was observed. The results of Western blot showed that orchinol could significantly down-regulate the protein expression levels of ß-catenin, Wnt3a, DvL2 and cyclinD1, and up-regulate the protein expression level of GSK-3ß(P<0.05, P<0.01, P<0.001). The above results suggest that orchinol can obviously inhibit the invasion and migration of SGC-7901 cells, which may be related to its inhibition of Wnt3a/ß-catenin signaling pathway and the proteins expression of downstream genes.
