Background
Fatty acid-binding protein; adipocyte; also known as Adipocyte-type fatty acid-binding protein; Fatty acid-binding protein 4; Adipocyte lipid-binding protein; and FABP4; is a cytoplasm protein which belongs to thecalycin superfamily and Fatty-acid binding protein (FABP) family. In familial combined hyperlipidemia (FCHL); FABP4 correlated to body mass index (BMI); waist circumference and homeostasis model assessment (HOMA) index.FABP4 levels were associated with triglyceride-rich lipoproteins. In humans serum FABP4 levels correlate significantly with features of PCOS. It appears to be a determinant of atherogenic dyslipidemia. FABP4 pathway mediates the sebaceous gland hyperplasia in keratinocyte-specific Pten-null mice. FABP4 concentration significantly increased with an increasing of MS features and was strongly correlated with body-mass index; triglycerides; HDL-cholesterol concentrations and blood pressure. Patients in the highest quartile of FABP4 presented a six-fold increased odds ratio for MS and a three-fold increased odds for LD; adjusted by age; sex; body-mass index and the antiretroviral therapy. FABP4 is a strong plasma marker of metabolic disturbances in HIV-infected patients; and therefore; could serve to guide therapeutic intervention in this group of patients.
