Odor: characteristic
Use: Germacrone treatment significantly inhibited cell proliferation, increased lactate dehydrogenase (LDH) release, and induced mitochondrial membrane potential (??m) depolarization in both MCF-7 and MDA-MB-231 cells in a dose-dependent manner. Germacrone induced MDA-MB-231 and MCF-7 cell cycle arrest at the G0/G1 and G2/M phases respectively and induced MDA-MB-231 cell apoptosis. Furthermore, germacrone treatment significantly increased Bok expression and cytochrome c release from mitochondria without affecting Bcl-2, Bcl-xL, Bax, and Bim protein expressions. In addition, germacrone treatment induced caspase-3, 7, 9, PARP cleavage. We concluded that germacrone inhibited the proliferation of breast cancer cell lines by inducing cell cycle arrest and apoptosis through mitochondria-mediated caspase pathway. These results might provide some molecular basis for the anti-tumor activity of Rhizoma curcuma. Germacrone might be a new potent chemopreventive drug candidate for liver cancer via regulating the expression of proteins related to G2/M cell cycle and apoptosis, and p53 and oxidative damage may play important roles in the inhibition of human hepatoma cells growth by germacrone.
