S. anginosus promotes apoptosis of SCC15 and inhibits the proliferation through a cell cycle arrest at the G1/S transition. a CCK-8 assay was performed to test cell proliferation of SCC15 cells. b The cell cycle distributions of SCC15 cells were analyzed with flow cytometry. c Cell apoptosis rate was measured by flow cytometry. Data were representative of three independent experiments and shown as mean ± SD, *: P < 0.05, **: P < 0.01 as versus blank control group
