- Paper Abstract
- alpha-Conidendrin is a polyphenolic compound found mainly in Taxus yunnanensis, as the source of chemotherapy drug paclitaxel, which has been used in traditional medicine for treatment of cancer. This study aimed to investigate the anticancer activity and molecular mechanisms of alpha-conidendrin on breast cancer cell lines. The results of the present study show that alpha-conidendrin possesses potent antiproliferative effects on breast cancer cell lines MCF-7 and MDA-MB-231. alpha-Conidendrin significantly induced apoptosis in breast cancer cells via reactive oxygen species generation, upregulation of p53 and Bax, downregulation of Bcl-2, depolarization of mitochondrial membrane potential (MMP), release of cytochrome c from mitochondria, and activation of caspases-3 and -9. alpha-Conidendrin remarkably inhibited the proliferation of breast cancer cells through induction of cell cycle arrest by upregulating p53 and p21 and downregulating cyclin D1 and CDK4. Unlike breast cancer cells, the antiproliferative effect of alpha-conidendrin on human foreskin fibroblast cells (normal cells) was very small. In normal cells, reactive oxygen species levels, loss of MMP, release of cytochrome c, mRNA expression of p53, p21, cyclin D1, CDK4, Bax, and Bcl-2 as well as mRNA expression and activity of caspases-3 and -9 were significantly less affected by alpha-conidendrin compared with cancer cells. These results suggest that alpha-conidendrin can be a promising agent for treatment of breast cancer with little or no toxicity against normal cells.
