  A better understanding of the control of lipogenesis is of critical importance for both human and animal physiology.This requires a better knowledge of the changes of gene expression during the process of adipose tissue development.Thus,the objective of the current study was to determine the effects of development on subcutaneous adipose tissue gene expression 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(P < 0.05).A set of universally abundant genes(ATP8,COX2,COX3,ND1,ND2,SCD and TUBA1B)was found across all four developmental stages.This set of genes may play important roles in lipogenesis and development.We 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.

引言猪高致病性蓝耳病(PRRS)、口蹄疫(MFD)都属于急性、烈性、病毒性的一类猪重大传染病,往往给养猪场和养殖户带来巨大经济损失.养猪生产中,由于各养殖场饲养猪品种不一样,在发生高致病性蓝耳病、口蹄疫等疫情时往往表现出明显的品种间差异,对猪场生产成绩影响差异也大.通过临床观测发现,在猪场发生高致病性蓝耳病、口蹄疫时,黑猪相较外种猪表现出明显的抗病力.现将观测结果报道如下.
