Maturation of the expression of adrenomedullin, endothelin-1 and nitric oxide synthases in adipose tissues from childhood to adulthood

OBJECTIVE: To investigate if the vasoactive systems adrenomedullin (ADM) and endothelin-1 (ET-1) are expressed in human adipose tissues in children and in adults and to determine the distribution pattern of nitric oxide synthases (NOS). DESIGN AND SUBJECTS: Subcutaneous, mesenterial and omental adip...

description OBJECTIVE: To investigate if the vasoactive systems adrenomedullin (ADM) and endothelin-1 (ET-1) are expressed in human adipose tissues in children and in adults and to determine the distribution pattern of nitric oxide synthases (NOS). DESIGN AND SUBJECTS: Subcutaneous, mesenterial and omental adipose tissue specimens taken from 15 children (age 0.5–16 y, median 6 y) and 13 adults (age 43–79 y, median 60 y) were analyzed. The body mass indices (BMI) were within the normal range. All patients were normotensive, and were free of infectious disease, and metabolic or endocrine disorders. The specimens were taken during elective laparotomies after informed consent was obtained. MEASUREMENTS: ADM, ET-1, the endothelial (eNOS) and inducible (iNOS) NOS as well as two housekeeping genes were measured using quantitative real-time PCR. RESULTS: ADM gene expression was found at all locations, and was significantly higher in adults than in children ( P

ET-1 mRNA was distributed in a similar way, showing significantly higher levels in the subcutaneous and mesenterial adipose tissue sections of adults than of children.

CONCLUSION: Human adipose tissue expresses many vasoactive substances including ADM and ET-1. In adults, the amounts of ET-1 and ADM as well as eNOS and iNOS mRNA are higher, possibly due to a physiological upregulation with increasing age. Although there are differences depending on the locations of the tissues, the expression patterns of the antagonists ADM and ET-1 are quite similar, indicative of a well-balanced pattern of local gene expression in normotensive individuals with normal body weight.</description><identifier>ISSN: 0307-0565</identifier><identifier>EISSN: 1476-5497</identifier><identifier>DOI: 10.1038/sj.ijo.0802885</identifier><identifier>PMID: 15672108</identifier><identifier>CODEN: IJOBDP</identifier><language>eng</language><publisher>London: Nature Publishing Group UK</publisher><subject>Adipocytes ; Adipose tissue ; Adipose Tissue - metabolism ; Adolescent ; Adrenomedullin ; Adult ; Adults ; Aged ; Aging - metabolism ; Biological and medical sciences ; Body fat ; Body Mass Index ; Body weight ; Child ; Child, Preschool ; Endocrine disorders ; Endothelin-1 - genetics ; Endothelin-1 - metabolism ; Epidemiology ; Female ; Gene expression ; Gene Expression Regulation, Developmental ; Health Promotion and Disease Prevention ; Humans ; Infant ; Infectious diseases ; Insulin ; Internal Medicine ; Laparotomy ; Male ; Medical sciences ; Medicine ; Medicine &amp; Public Health ; Mesentery - metabolism ; Metabolic Diseases ; Metabolism ; Middle Aged ; Nitric oxide ; Nitric Oxide Synthase - genetics ; Nitric Oxide Synthase - metabolism ; Nitric Oxide Synthase Type II ; Nitric Oxide Synthase Type III ; Obesity ; Omentum - metabolism ; Peptides ; Peptides - genetics ; Peptides - metabolism ; Physiology ; Public Health ; RNA, Messenger - genetics ; Subcutaneous Tissue - metabolism</subject><ispartof>International Journal of Obesity, 2005-03, Vol.29 (3), p.275-280</ispartof><rights>Springer Nature Limited 2005</rights><rights>2005 INIST-CNRS</rights><rights>COPYRIGHT 2005 Nature Publishing Group</rights><rights>Copyright Nature Publishing Group Mar 2005</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c576t-1ccb581ba770c094cf057474a59a9fd25a5ea3d142343f8c8e444b2298c261043</citedby><cites>FETCH-LOGICAL-c576t-1ccb581ba770c094cf057474a59a9fd25a5ea3d142343f8c8e444b2298c261043</cites></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,780,784,2727,27924,27925</link.rule.ids><backlink>$$Uhttp://pascal-francis.inist.fr/vibad/index.php?action=getRecordDetail&amp;idt=16525912$$DView record in Pascal Francis$$Hfree_for_read</backlink><backlink>$$Uhttps://www.ncbi.nlm.nih.gov/pubmed/15672108$$D View this record in MEDLINE/PubMed$$Hfree_for_read</backlink></links><search><creatorcontrib>Knerr, I</creatorcontrib><creatorcontrib>Schirl, C</creatorcontrib><creatorcontrib>Horbach, T</creatorcontrib><creatorcontrib>Stuppy, A</creatorcontrib><creatorcontrib>Carbon, R</creatorcontrib><creatorcontrib>Rascher, W</creatorcontrib><creatorcontrib>Dötsch, J</creatorcontrib><title>Maturation of the expression of adrenomedullin, endothelin-1 and nitric oxide synthases in adipose tissues from childhood to adulthood</title><title>International Journal of Obesity</title><addtitle>Int J Obes</addtitle><addtitle>Int J Obes (Lond)</addtitle><description>OBJECTIVE: To investigate if the vasoactive systems adrenomedullin (ADM) and endothelin-1 (ET-1) are expressed in human adipose tissues in children and in adults and to determine the distribution pattern of nitric oxide synthases (NOS).
