Effectiveness of DN against U2OS osteosarcoma cells. (A): U2OS cells treated with vehicle or 100 µg/mL extracts for 48 h. Apoptosis indexes (Cleaved Caspase-3 and PARP) were detected via western blotting. GAPDH served as the internal control. (B): U2OS cells treated with vehicle or 5 µM of each compound for 24 h.
