Abstract

Prunellae Spica is a flower petal of Prunella vulgaris var. lilacina used for treatment of lymphoma, breast cancer, hepatitis and pathological fluid related diseases in oriental medicine. We tried to evaluate the mechanism of Prunellae Spica in the treatment of cancer. The ethyl acetate layer of Prunellae Spica showed a good cytotoxicity on U937 cells with IC50 of 8 ug/ml. It induced apoptosis in U937 dose-dependently by cell cycle analysis following PI staining. We also confirmed it induced DNA fragmentation in U937 cells from the concentration of 10 ug/ml. From western blot assay we observed the ethyl acetate layer of Prunellae Spica downregulated procaspase-3 and cleaved PARP in a dose dependent manner, whereas it didn't affect bax and bcl-2. Taken together, these results indicate the ethyl acetate layer of Prunellae Spica can induce apoptosis in U937 cells suggesting it can be potently applied to cancer.
