Dietary fatty acids regulate the activation status of Her-2/neu (c-erbB-2) oncogene in breast cancer cells
| The first 10% of the full text of this article appears below. |
Research from several sources provides strong evidence that dietary or exogenously derived fatty acids (FAs) may play an important role in the etiology, evolution and/or progression of breast cancer [1
]. However, the type of individual FAs in a diet, rather than the amount of total dietary fat, may be more important in breast cancer disease. In this regard, epidemiological, experimental and mechanistic data implicate
-9 oleic acid (OA; 18:1n-9), the main FA of olive oil,
-linolenic acid (ALA; 18:3n-3), the
-3 FA of vegetable oils, and eicosapentaneoic (EPA; 22:5n-3) and docosahexaenoic (DHA; 22:6n-3) FAs, the two main
-3 FAs of fish oils, as inhibitors of the development and progression of human breast cancer, and
-6 FAs such as linoleic acid (LA; 18:2n-6), the main FA of corn and sunflower oils, as stimulators of the disease. Moreover, one of the most
