FABP4 and metabolic syndrome: To understand the mechanism of action of CPE and CFSE in improving hyperglycemia and dyslipidemia, the mRNA levels of PPARγ and its target genes including aP2 (adipocyte fatty-acid-binding protein), ACC (acetyl-CoA carboxylase) and FAS (fatty acid synthase) were analyzed in the liver tissue as shown in Figure 5A.
