Effects of Panax ginseng extract heat-processed with arginine and ginsenoside 20(S)-Rg3 on apoptosis in A2780 cells. Western blotting results showing the levels of cleaved caspase-3, cleaved caspase-8, cleaved caspase-9, BID, and PARP in A2780 cells treated with heat-processed Panax ginseng extract with arginine (500 μg/mL) and ginsenoside 20(S)-Rg3 (12.5 μg/mL) for 24 h. Thirty micrograms of each protein was separated by SDS-PAGE. GAPDH was used as an internal control.
