title: Tissue- and breed-specific expression of the chicken fat mass- and obesity-associated gene (FTO).
abstract: The fat mass- and obesity-associated gene (FTO) is involved in energy metabolism, but little is known about the chicken FTO gene. The objective of the current study was to detect chicken FTO expression patterns in the hypothalamus, liver, and skeletal muscle during development, and analyze the effects of age and breed on FTO expression. Real-time quantitative polymerase chain reaction results revealed that chicken FTO mRNA was expressed in all of the tissues tested. Chicken FTO exhibited tissue- and breed-specific patterns in the recessive White Plymouth Rock chicken and the Qingyuan partridge chicken. The highest FTO expression level was in the hypothalami of 1-week-old chicks. FTO mRNA was expressed more in the breast muscles and livers of recessive White Plymouth Rock chickens than those of Qingyuan partridge chickens at 1 and 8 weeks of age. These results indicate that FTO probably plays a significant role in energy metabolism at 1 week old, when chicks have undergone metabolic adaptations from yolk dependence to the utilization of exogenous feed.
