Antitumor Effect of Periplocin in TRAIL-Resistant Human Hepatocellular Carcinoma Cells through Downregulation of IAPs
Figure 1
The effect of cortex periplocae extracts on HCC cell viability. (a) The chemical structures and names of purified cortex periplocae extracts are listed. (b) The cell viability of HA22T/VGH cells was determined by MTT assay after cells were treated with different concentrations of the indicated compound (0.03, 0.1, 0.3, 1, 3, and 10 μM) with or without TRAIL (T) for 48 h.
