Gene Expression Patterns of Geese Expression Patterns of L-FABP, Spot 14, OB and APO A1 Genes in Different Tissues of Overfed and Control Geese

Abstract

Ten-week-old Langde geese in similar body weight were randomly selected, four for overfeeding and four for routinly feeding. The abundance of liver fatty acid-binding protein (L-FABP), thyroid hormoneresponsive (THRSP or Spot 14), obese (OB), and apolipoprotein A1 (Apo A1) genes in goose were detected by quantitative RT-PCR. L-FABP was higher expressed in liver and intestine than other tissues, but no expression was detected in the pancreas or brain. The other three genes were widely expressed in different tissues, OB was higher expressed in pancreas and abdominal fat, Spot 14 and Apo A1 was higher expressed in sebum and abdominal fat. Spot 14 and Apo A1 genes were upregulated in overfed goose livers compared with that in the control. Thus, Spot 14 and Apo A1 genes may play important roles in lipid metabolism in goose fat liver.
