Plumbagin (0, 5, 10, and 15 μM) induces apoptosis of prostate cancer cell lines, such as DU145, CWR22rv1 and LNCaP, in a dose-dependent manner.
Plumbagin (5, 20 μM) obviously inhibits the invasion of PC3, DU145, and CWR22rv1 cells.

Plumbagin (2 mg/kg, i.p., five days a week for 11 weeks) inhibits the growth of tumor in male athymic nude mice.
Plumbagin (2 mg/kg, i.p., five days a week for 11 weeks) inhibits expression of PKCε, suppresses JAK-2 and Stat3 phosphorylation, and activates Stat3, PCNA, VEGF and MMP-9 in mice.
