Auraptene Induces Apoptosis via Myeloid Cell Leukemia 1-Mediated Activation of Caspases in PC3 and DU145 Prostate Cancer Cells.
    Phytotherapy research : PTR, 2017, Volume: 31, Issue:6

    Although auraptene, a prenyloxy coumarin from Citrus species, was known to have anti-oxidant, anti-bacterial, antiinflammatory, and anti-tumor activities, the underlying anti-tumor mechanism of auraptene in prostate cancers is not fully understood to date. Thus, in the present study, we have investigated the anti-tumor mechanism of auraptene mainly in PC3 and DU145 prostate cancer cells, because auraptene suppressed the viability of androgen-independent PC3 and DU145 prostate cancer cells better than androgen-sensitive LNCaP cells. Also, auraptene notably increased sub-G1 cell population and terminal deoxynucleotidyl transferase dUTP nick end labeling-positive cells as features of apoptosis in two prostate cancer cells compared with untreated control. Consistently, auraptene cleaved poly(ADP-ribose) polymerase, activated caspase-9 and caspase-3, suppressed the expression of anti-apoptotic proteins, including Bcl-2 and myeloid cell leukemia 1 (Mcl-1), and also activated pro-apoptotic protein Bax in both prostate cancer cells. However, Mcl-1 overexpression reversed the apoptotic effect of auraptene to increase sub-G1 population and induce caspase-9/3 in both prostate cancer cells. Taken together, the results support scientific evidences that auraptene induces apoptosis in PC3 and DU145 prostate cancer cells via Mcl-1-mediated activation of caspases as a potent chemopreventive agent for prostate cancer prevention and treatment.

Protective effects of citrus nobiletin and auraptene in transgenic rats developing adenocarcinoma of the prostate (TRAP) and human prostate carcinoma cells.
    Cancer science, 2007, Volume: 98, Issue:4

    Dietary phytochemicals, including nobiletin and auraptene, have been shown to exert inhibiting effects in several chemically induced carcinogenesis models. We here investigated the influence of nobiletin and auraptene on prostate carcinogenesis using transgenic rats developing adenocarcinoma of the prostate (TRAP) bearing the SV40 T antigen transgene under control of the probasin promoter and human prostate cancer cells. Starting at 5 weeks of age, male TRAP rats received powder diet containing 500 p.p.m. nobiletin or auraptene, or the basal diet for 15 weeks and then were sacrificed for analysis of serum testosterone levels and histological changes. The body and relative prostate weights and serum testosterone levels did not differ among the groups. Since all animals developed prostate carcinomas, these were semiquantitatively measured and expressed as relative areas of prostate epithelial cells. Nobiletin caused significant reduction in the ventral (P<0.01), lateral (P<0.001) and dorsal (P<0.05) prostate lobes, while decreasing high grade lesions (P<0.05) in the ventral and lateral lobes. Feeding of auraptene also effectively reduced the epithelial component (P<0.05) and high grade lesions (P<0.05), in the lateral prostate. A further experiment demonstrated that growth of androgen sensitive LNCaP and androgen insensitive DU145 and PC3 human prostate cancer cells, was suppressed by both nobiletin and to a lesser extent auraptene in a dose-dependent manner, with significant increase in apoptosis. In conclusion, these compounds, particularly nobiletin, may be valuable for prostate cancer prevention.
