From: Combined xanthorrhizol-curcumin exhibits synergistic growth inhibitory activity via apoptosis induction in human breast cancer cells MDA-MB-231

Figure 5

Simultaneous treatment of xanthorrhizol and curcumin induces DNA fragmentation in MDA-MB-231 cells. At lower doses of treatment, only high molecular weight intact DNA was observed whereas small fragments of DNA were highlighted at higher doses of treatment. The fragments of DNA have interval molecular weight of ~180 bp, suggesting an apoptotic event. Results are representative of three independent experiments carried out. M – Marker. 0, 5, 10, 15, 20, 25 μg/ml – DNA samples from xanthorrhizol-curcumin (XC)-treated cells at different concentration. T – DNA sample from taxol-treated MDA-MB-231 cells (positive control). C – DNA sample from actinomycin-treated HL 60 cells (positive control).
