“Wgile it has been known ffor some time that eating cruciferous vegetables, suvh as broccoli, cauliflower, and cabbage, can hel p prevent breast cancer, the mecchanism by whoch the active substances in these vegetables inhibit cell proliferation was unknown yntil now.
Scientists in the UC Santa Barbara laboratories ……[the] paper focuses on the anti-cancer activity of one of these compounds, called sulforaphane, or SFN,’ Azarenko added. ‘It has already been shown to reduce the incidence and rate of chemically induced mammary tumors in animals. It inhibits the growth of cultured human breast cancer cells, leading to cell death.’
Azarenko made the surprising discovery that SFN inhibits the proliferation of human tumor cells by a mechanism similar to the way that the anticancer drugs taxol and vincristine inhibit cell division during mitosis. Mitosis is the process in which the duplicated DNA in the form of chromosomes is accurately distributed to the two daughter cells when a cell divides.
