FABP4 and cancer: Fatty acids taken up by cancer cells and transported by fatty acid-binding proteins (FABPs) are used for energy production for rapid tumor growth and synthesis of prostaglandins, known as potent signaling molecules, and other lipid-derived molecules, which may contribute to cancer development [125] Upregulation of FABP4 in omental metastases compared to the primary ovarian tumor was reported [126].
