Broccoli Compound Helps Stop Breast Cancer Cell Growth?
Jackson SJ, Singletary KW. Sulforaphaneforaphane inhibits
human mcf-7 mammary cancer cell mitotic progression and tubulin
polymerization. J Nutr. 2004 Sep;134(9):2229-36.
Sulforaphane, a plant compound found in broccoli, cauliflower,
Brussels sprouts, cabbage, kale, collard greens and other cruciferous
vegetables, has been shown to stop the growth of human breast cancer
cells in a study conducted at the University of Illinois. In this
study, cancerous mammary cells were exposed to increasing dosages
of sulforaphane over a 48-hour period. Within hours, cell division
was blocked. The reason: sulforaphane disrupts microtubules, cell
components necessary for separating duplicated chromosomes during
cell division. The reproduction of the cancer cells was inhibited
in a dose-dependent manner, meaning the more sulforaphane the cells
were exposed to, the stronger the brake put on cell growth. But,
even at low doses, DNA synthesis in both estrogen receptor positive
(ER+) and estrogen receptor negative (ER-) cells was significantly
inhibited.
Sulforaphane has been found to have cancer preventive properties
in previous studies by inhibiting cancer initiation, and this study
demonstrates that it may also affect breast cancer promotion and
progression.
