Tuesday Dec 23, 2008 (foodconsumer.org) -- Many vegetables
are known to prevent cancer. Eating cruciferous vegetables such as broccoli, cauliflower,
and cabbage can help reduce risk of breast cancer.
A new study by Mary Ann Jordan and colleagues at the
University of California in Santa Barbara showed sulforaphane or SFN found in
broccoli prevents cancer by inhibiting cell division during mitosis.
SFN has been found early to reduce the incidence and rate
of chemically induced mammary tumors in animals and inhibit the growth of
cultured human breast cancer cells.
Mitosis is a process in which the duplicated DNA in the
form of chromosomes is distributed to the two daughter cells when a cell
divides, according to a press release by the university. The cells use hundreds
of tiny tube-like structures called microtubules to separate the chromosomes.
The study published in this month's journal
Carcinogenesis showed SFN interferes with microtubule functioning during the
process.
