Histone deacetylase activity and vitamin D-dependent gene expressions in relation to sulforaphane in human breast cancer cells.

Breast cancer (BC) affects a large number of the U.S. population each year. Like most cancers, nutrition does play a role in the prevention of BC. However, dietary advice that includes reducing alcohol intake, red meat, and saturated fat consumption, while increasing the intake of heart-healthy fats, dietary fiber, and lean protein, etc., is difficult to apply to all cancers from a preventative standpoint. Vitamin D has been implicated in BC, mostly as a protective factor, with mixed findings. This research focuses on the role of vitamin D as a protective intervention in human BC, along with a dietary bioactive compound-sulforaphane. The idea is to combine the known benefits of a micronutrient with potential benefits of the bioactive compound to establish a stronger intervention against BC progression, irrespective of the subtype.
