abstract = {ObjectiveTo study the effects of hedysarum polybotys saccharides (HPS) and selenizated hedysarum polybotys saccharides (SE-HPS) on the oral squamous cancer cell line SCC25.MethodsDifferent concentrations (0, 10, 25, 50, 100, 200, 400 μg/ml) of HPS and SE-HPS were added to SCC25 cells in the logarithmic growth stage. Cell proliferation was detected by the CCK-8 method, apoptosis was detected by flow cytometry, and apoptosis-related indexes were observed by RT-qPCR and Western blotting.ResultsThe concentrations of HPS and SE-HPS inhibited the proliferation of SCC25 cells. The inhibitory effect of 50 μg/mL HPS and SE-HPS on the proliferation of SCC25 cells was the strongest and was time-dependent. The inhibition effect significantly increased within 48 h, and the effect was achieved after 48 h. At the plateau stage, SE-HPS inhibited the proliferation of SCC25 cells more strongly than HPS (P < 0.05). The results of flow cytometry showed that 50 μg/mL HPS and SE-HPS acted on SCC25 cells for 48 h, and the apoptotic rates were 25.8% and 30.8% respectively. Compared with the control group (0 μg/mL HPS and SE-HPS), the difference was statistically significant (P < 0.05). RT-qPCR and Western blotting showed that 50 μg/mL HPS and SE-HPS acted on SCC25 cells for 48 h, and the mRNA and protein expression levels of the apoptosis gene Fas/FasL were upregulated. The difference was statistically significant (P < 0.05).ConclusionBoth HPS and SE-HPS can inhibit the proliferation of SCC25 oral cancer cells, but SE-HPS is superior to HPS and can induce apoptosis through the Fas/Fasl pathway.}
