Modulation of breast cancer cell adhesion by unsaturated fatty acids

Nutrition

Abstract

Triglycerides, which are major constituents of dietary fat, contain a mixture of saturated and unsaturated fatty acids. One newly recognized function of unsaturated fatty acids is modulation of cell adhesion to components of the extracellular matrix. Alterations in cell adhesiveness or cell adhesion molecule expression accompany the onset of a number of diseases including arthritis, atherosclerosis, and cancer. Cell adhesion is necessary for the metastatic spread of cancer cells to new organs. Circulating cancer cells adhere to endothelial cells and the underlying subendothelial basement membrane as an initial step in the process of invading target organs during metastasis. Several recent studies have provided convincing evidence that unsaturated fatty acids and their metabolites influence adhesion of cultured human cancer cells to individual components of the basement membrane. These unsaturated fatty acid effects appear to be dependent in some instances on the expression of specific cell surface adhesion molecules. Unsaturated fatty acids influence the development of metastases in animal tumor models by largely unexplored mechanisms; the possibility that cell adhesion is involved in this process has not been thoroughly invest...Continue Reading

Adhesion Molecules in Health and Disease

Cell adhesion molecules are a subset of cell adhesion proteins located on the cell surface involved in binding with other cells or with the extracellular matrix in the process called cell adhesion. In essence, cell adhesion molecules help cells stick to each other and to their surroundings. Cell adhesion is a crucial component in maintaining tissue structure and function. Discover the latest research on adhesion molecule and their role in health and disease here.
