Fig. 5From: Cistanche tubulosa phenylethanoid glycosides induce apoptosis in H22 hepatocellular carcinoma cells through both extrinsic and intrinsic signaling pathwaysThe levels of cleaved-caspases and cleaved-PARP. H22 cells were treated with different concentrations of CTPG for 24 h. Total protein was isolated to detect the levels of cleaved-caspases and cleaved-PARP by Western blotBack to article page
