Thus, the increased expression of the fatty acid synthase gene (FAS) predicts shorter survival [40], dietary fat intake and altered lipid metabolism are linked to ovarian cancer risk [41] and in a mouse model tumor growth and invasion are fueled by direct transfer of lipids from omental adipocytes to ovarian cancer with a key role for fatty acid-binding protein 4 [42]. The gene discussed is FASN; the disease is ovarian cancer.
