Fig. 4From: Cistanche tubulosa phenylethanoid glycosides induce apoptosis in H22 hepatocellular carcinoma cells through both extrinsic and intrinsic signaling pathwaysThe reduction of Δψm and release of cytochrome c. H22 cells were treated with different concentrations of CTPG for 24 h. (a) Cells were stained with JC-1 dye and analyzed by flow cytometry. The individual dot plots show the changes of JC-1 fluorescence. The summary data are shown in the lower panel. (b) Total protein was isolated to detect the release of cytochrome c by Western blot. * p < 0.05; *** p < 0.001 compared to controlBack to article page
