FABP4 and neoplasm: In a previous study, we demonstrated that loss of A-FABP (Adipocyte-Fatty Acid Binding Protein/FABP4/aP2) expression was correlated with high tumor stage and high histological grade in UC More precisely, the weak expression of A-FABP in resected primary NMIBC group was a higher risk factor of progression associated with poorer prognosis10.
