Abundance of duck adipocyte fatty acid-binding protein (A-FABP) mRNA was detected in this study by quantitative real-time PCR. The results showed that duck A-FABP gene was expressed in muscular tissues and many organs, except pancreas, lung, and kidney, and highly expressed in adipose tissues, especially in sebum. The expression of A-FABP and adipocyte differentiation-related genes was upregulated by oleic acid, and the A-FABP knockdown suppressed the oleic acid-stimulated expression of these genes in the cultured duck adipocytes, indicating A-FABP might play an important role in duck adipocyte differentiation.
