To determine whether fatty acid metabolism is altered in ovarian cancer tissue, we first evaluated the gene expression of fatty acid synthases (ACC1, FASN), fatty acid desaturases (SCD1, FADS1, FADS2) and fatty acid elongase 1–6 (ELOVL1–6) in ovarian tumor tissues and normal ovarian tissues. Here, ELOVL1 is linked to ovarian neoplasm.
