BBM and SORA synergistically
induce HCC cell apoptosis. (A) Single-agent
treatment with BBM (10 μM), SORA (10 μM) alone, or combined
treatment with BBM (10 μM) and SORA (10 μM) for 48 h.
Apoptosis was analyzed using Annexin V/propidium iodide (PI) staining.
Data were compiled from three independent experiments and reported
in the form of mean ± SD. All of the experiments were performed
in triplicate. (B) Extraction of total protein and detection of the
expression of cleaved PARP, cleaved caspase 3, and Bcl-2 using western
blotting. Actin was shown as the control of equal loading. (C) Quantification
of the relative expression of apoptosis-related proteins (cleaved
PARP/actin, cleaved caspase 3/actin, and Bcl-2/actin) using ImageJ
software and analysis with Graphpad prism 7. **P <
0.01 compared to the negative control.
