摘 要：A better understanding of the control of lipogenesis is of critical importance for both human and animal *** requires a better knowledge of the changes of gene expression during the process of adipose tissue ***,the objective of the current study was to determine the effects of development on subcutaneous adipose tissue gene ex-pression in growing and adult pigs. Here, we present a comprehensive investigation of mRNA transcriptomes in porcine subcutaneous adipose tissue across four developmental stages using digital gene expression profiling. We identified 3 274 differential expressed genes associated with oxidative stress, immune processes, apoptosis, energy metabolism, insulin stimulus,cell cycle, angiogenesis and translation(P0. 05). A set of universally abundant genes(ACOX3,iVD』,A/D2,SCD and 7T/BAJB) was found across all four developmental stages. This set of genes may play important roles in lipogenesis and *** also identified development-related gene expression patterns that are linked to the different adipose phenotypes. We showed that genes enriched in significantly up-regulated profiles were associated with phosphorylation and angiogenesis. In contrast, genes enriched in significantly down-regulated profiles were related to cell cycle and cytoskeleton organization, suggesting an important role for these biological processes in adipose growth and development. These results provide a resource for studying adipose development and promote the pig as a model organism for researching the development of human obesity, as well as being used in the pig industry.
