Casticin-induced apoptosis involves death receptor 5 upregulation in hepatocellular carcinoma cells

Figure 7 Effects of casticin on the levels of death receptors (DR4 and DR5) expression(A) using Western blotting and the percentage sub-G1 cell population (B) in PLC/PRF/5 cells (mean ± SD, n = 3). ^aP < 0.05 vs treatment with dimethyl-sulfoxide (DMSO); ^bP < 0.05 vs treatment with 30 μmol/L casticin alone. C: Effects of casticin on the levels of death receptor (DR)4 and DR5 protein levels on the surface of Hep G2 cells using flow cytometry. NAC: N-acetyl-cysteine.
