Chrysophanol Regulates Cell Death, Metastasis, and Reactive Oxygen Species Production in Oral Cancer Cell Lines

Figure 2

Chrysophanol induced apoptosis in FaDu and SAS. (a) Cell death via apoptosis was described by the SubG1 population of FaDu and SAS in the absence (control) and presence of chrysophanol (30 and 70 μm). (b) The quantification in fold-changes of the SubG1 population. (c) The expressions of procaspase 3 and cleaved-caspase 3 (c-caspase-3) were analyzed by western blotting. (d) TUNEL staining showing the apoptotic phenomena (arrow) induced by chrysophanol in FaDu and SAS cell lines. Bar = 200 μm. All data are presented as mean ± SEM, n = 3. . compared with control (Ctrl or 0 μm).
