ABSTRACT
ChREBP (carbohydrate-responsive element-binding protein) plays a crucial role as a central regulator of lipid synthesis and glycolysis in animal liver. In this study, the relative quantitative real-time PCR analysis indicated that the duck ChREBP mRNA is widely expressed in all examined tissues. ChREBP mRNA level was the highest in abdominal fat and the lowest in gizzard. The g.247075G>A silent mutation in exon 10 was first identified by direct sequencing approach, and resulted in three genotypes of AA, GA and GG. Association analysis demonstrated that the liver ChREBP mRNA expression level was significantly positive or negative effect on serum total protein (TP), albumin (Alb), triglyceride (TG), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C) (P<0.05 or P<0.01). The g.247075G>A mutation was significantly association with these measured serum biochemical indexes except for LDL-C. Significant additive effects were detected for all detected serum biochemical indexes except for LDL-C between allele A and G, and significant dominance effects for TP. These findings suggested that ChREBP might be a crucial candidate genes for the selection of duck lipid content.
