We hypothesized that this may result from poor nutrition during early life exerting permanent effects on the structure and function of key metabolic organ systems. To study the long-term impact of early-life undernutrition on susceptibility to visceral adiposity, we used a rat model of maternal protein restriction (MPR) in which dams were fed a low-protein diet (containing 8% instead of 20% protein in control diet) throughout pregnancy and lactation. MPR offspring were born smaller than controls (offspring of dams on control diet) and in adulthood developed visceral adiposity. We compared the pattern of gene expression in visceral adipose tissue (VAT) between MPR offspring and controls with Affymetrix rat expression arrays. Of the total number of genes and expressed sequence tags analyzed (15,923 probe sets), 9,790 (61.5%) were expressed in VAT. We identified 650 transcripts as differentially expressed \u22651.5-fold in the VAT of MPR offspring. Gene ontology analysis revealed a global upregulation of genes involved in carbohydrate, lipid, and protein metabolism. A number of genes involved in adipocyte differentiation, angiogenesis, and extracellular matrix remodeling were also upregulated. However, in marked contrast to other rodent models of obesity, the expression of a large number of genes associated with inflammation was reduced in this rat model. Thus visceral adiposity in this early-life programmed rat model is marked by dynamic changes in the transcriptional profile of VAT. Our data provide new insights into the molecular mechanisms that underlie the early-life programming of visceral adiposity.<\/jats:p>","DOI":"10.1152\/ajpendo.00461.2004","type":"journal-article","created":{"date-parts":[[2004,11,24]],"date-time":"2004-11-24T03:24:50Z","timestamp":1101266690000},"page":"E663-E673","source":"Crossref","is-referenced-by-count":130,"title":["Adipose tissue gene expression profiling reveals distinct molecular pathways that define visceral adiposity in offspring of maternal protein-restricted rats"],"prefix":"10.1152","volume":"288","author":[{"given":"Haiyan","family":"Guan","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Edith","family":"Arany","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jonathan P.","family":"van Beek","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Astrid","family":"Chamson-Reig","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sandra","family":"Thyssen","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"David J.","family":"Hill","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kaiping","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"24","reference":[{"key":"R1","doi-asserted-by":"crossref","unstructured":"Abrahamson M, Alvarez-Fernandez M, and Nathanson CM.Cystatins.Biochem Soc Symp: 179\u2013199, 2003.","DOI":"10.1042\/bss0700179"},{"key":"R2","doi-asserted-by":"publisher","DOI":"10.1097\/00075197-200207000-00006"},{"key":"R3","unstructured":"Bahamonde MEand Lyons KM.BMP3: to be or not to be a BMP.J Bone Joint SurgAm 83-A,Suppl1: S56\u2013S62, 2001."},{"key":"R3A","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.311.6998.171"},{"key":"R4","doi-asserted-by":"crossref","unstructured":"Bell GI, Quinto C, Quiroga M, Valenzuela P, Craik CS, and Rutter WJ.Isolation and sequence of a rat chymotrypsin B gene.J Biol Chem259: 14265\u201314270, 1984.","DOI":"10.1016\/S0021-9258(18)89887-8"},{"key":"R5","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.271.3.1784"},{"key":"R6","doi-asserted-by":"publisher","DOI":"10.1126\/science.1082095"},{"key":"R7","doi-asserted-by":"publisher","DOI":"10.1161\/01.RES.83.10.1059"},{"key":"R8","doi-asserted-by":"publisher","DOI":"10.1023\/A:1023823803510"},{"key":"R9","doi-asserted-by":"publisher","DOI":"10.1136\/jcp.53.11.822"},{"key":"R10","doi-asserted-by":"publisher","DOI":"10.1016\/S0962-8924(01)82222-4"},{"key":"R11","doi-asserted-by":"publisher","DOI":"10.1074\/jbc.M209196200"},{"key":"R12","doi-asserted-by":"publisher","DOI":"10.1016\/j.metabol.2003.10.017"},{"key":"R13","doi-asserted-by":"crossref","unstructured":"Clauser E, Gardell SJ, Craik CS, MacDonald RJ, and Rutter WJ.Structural characterization of the rat carboxypeptidase A1 and B genes.
