Increased extrinsic apoptotic pathway activity in patients with hepatocellular carcinoma following transarterial embolization

Figure 2 Representative immunoblot and relative intensities of cleaved caspase-9 (A), cleaved caspase-3 (B), Fas (C) and cleaved caspase-8 (D) proteins in the study and control groups. β-actin was used as a loading control. The asterisk indicates a significant difference between the study (HCC post-TAE) and control (HCC) groups. HCC: Hepatocellular carcinoma; TAE: Transarterial embolization.
