Abstract

Opuntia humifusa, widely distributed in the southern regions of the Korean peninsula, is known to have bioactive functions and medicinal benefits for treating various diseases such as arteriosclerosis, diabetes mellitus, gastritis, and hyperglycemia. In this study total polyphenol and flavonoid contents of fruit and its anticarcinogenic effects on human breast cancer were investigated. As expected, O. humifusa showed high concentrations of total polyphenol as well as flavonoid as compared to other kinds of cactus. Effects of the water extracts of O. humifusa on the proliferation, G1 arrest and apoptosis of the MCF-7 human breast cancer cells were also examined using the MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assays, and G1 cycle arrest and apoptotic effect of O. humifusa were analyzed by flow cytometry. When MCF-7 cells were treated with different concentrations of hexane, ethyl acetate and water extracts of O. humifusa, water extracts of the fruit significantly decreased viable cell numbers in a concentration dependent manner. A G1 arrest in MCF-7 cells was induced as well. The overall results indicate that water extracts of fruit of O. humifusa would inhibit MCF-7 human breast cancer cell proliferation and induce G1 arrest.
