Introduction
Fatty acid binding protein 4(FABP4), also termed adipocyte fatty acid binding protein (A-FABP), or aP2, is a novel
adipocyte-expressed factor which accounted for ~6% of total cellular proteins. Several animal experiments suggested that FABP-4
plays a key role in the link between obesity and various features of metabolic syndrome. Mice with targeted disruption of FABP-4
accompany FABP-5 almost completely protect against diet-induced obesity, insulin resistance, dyslipidemia, type 2 diabetes, and
fatty liver disease. Studies in human found FABP-4 serum levels were significantly increased in overweight and obese subjects,
which predicted the risk to develop metabolic syndrome and type 2 diabetes. Additionally, serum FABP-4 levels were associated with carotid atherosclerosis and coronary artery disease.
