ABSTRACT
Cluster of differentiation 36 (CD36) plays a crucial role in lipid sensing, innate immunity, atherogenesis, and glycolipid metabolism. This aims of this study were to delineate the CD36 mRNA expression profile in 16 duck tissues using relative quantitative real-time PCR and to screen single nucleotide polymorphisms (SNPs) in the duck CD36 gene by PCR-single strand conformation polymorphism and DNA direct sequencing. In addition, this study investigated CD36 gene expression, genetic variation, and their effect on serum biochemical indices in duck. The results showed that CD36 mRNA was expressed in all tissues, and was highly specific to the pituitary and large intestine, and to subcutaneous and abdominal fat. Furthermore, three genotypes of the SNP g.476593 T > C in exon 9 of the duck CD36 gene were identified MM, MN, and NN. The dominant genotype and allele were MM and M, with frequencies of 0.453 and 0.643, respectively. The genotype distributions deviated from Hardy-Weinberg equilibrium (P < 0.05) and achieved moderate levels of polymorphism in ducks. Correlation results showed that CD36 mRNA was significantly negatively correlated with triglycerides (P < 0.05), and significantly positively correlated with total protein, globulin, low-density lipoprotein cholesterol, and total cholesterol (P < 0.01). All serum biochemical indices measured, with the exception of triglycerides, in birds with the NN genotype were significantly higher than those in birds with the MM genotype. These findings demonstrated that CD36 might be an important genetic marker for the selection of lipid metabolism and meat quality traits in ducks.
