Whether increasing leptin transgene expression can overcome the diminution in leptin restraint was evaluated in ovx rats.<\/jats:p><jats:p><jats:italic>Research Methods and Procedures:<\/jats:italic> Enhanced leptin or green fluorescent protein (GFP; control) transgene expression was induced by a single intracerebroventricular injection of recombinant adeno\u2010associated viral vector encoding either leptin gene (<jats:italic>rAAV\u2010lep<\/jats:italic>) or GFP gene (<jats:italic>rAAV\u2010GFP<\/jats:italic>; control) in acutely and chronically ovx rats. Body weight and food intake responses were monitored weekly. White adipose tissue (WAT) mass and serum levels of WAT\u2010derived hormones, leptin, and adiponectin were analyzed at termination of the experiments.<\/jats:p><jats:p><jats:italic>Results and Discussion:<\/jats:italic> An increase in leptin transgene expression in the hypothalamus initiated soon after ovx blocked hyperphagia and body weight gain and markedly suppressed WAT mass and adipokines, leptin, and adiponectin. Similar suppression of weight gain and adiposity and serum leptin and adiponectin levels after intracerebroventricular <jats:italic>rAAV\u2010lep<\/jats:italic> injection in chronically ovx rats were observed concomitant with unchanged daily food intake. These findings are consistent with the hypothesis that in the absence of ovarian steroids, the existent insufficiency of leptin restraint at the hypothalamic level can be overcome with ectopic leptin expression, thereby reinstating central control on weight and adiposity.<\/jats:p>","DOI":"10.1038\/oby.2006.149","type":"journal-article","created":{"date-parts":[[2008,4,23]],"date-time":"2008-04-23T14:18:17Z","timestamp":1208960297000},"page":"1312-1319","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":26,"title":["Central Leptin Gene Therapy Blocks Ovariectomy\u2010Induced Adiposity"],"prefix":"10.1002","volume":"14","author":[{"given":"Rita","family":"Torto","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"St\u00e9phane","family":"Boghossian","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael G.","family":"Dube","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pushpa S.","family":"Kalra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Satya P.","family":"Kalra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2012,9,6]]},"reference":[{"key":"e_1_2_7_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0149-7634(05)80183-6"},{"key":"e_1_2_7_3_2","doi-asserted-by":"publisher","DOI":"10.1006\/frne.1996.0010"},{"key":"e_1_2_7_4_2","doi-asserted-by":"publisher","DOI":"10.1038\/sj.ijo.0801806"},{"key":"e_1_2_7_5_2","doi-asserted-by":"publisher","DOI":"10.1016\/S1043-2760(00)00352-0"},{"key":"e_1_2_7_6_2","doi-asserted-by":"publisher","DOI":"10.1152\/ajpendo.2001.280.2.E315"},{"key":"e_1_2_7_7_2","doi-asserted-by":"publisher","DOI":"10.1159\/000054717"},{"key":"e_1_2_7_8_2","doi-asserted-by":"publisher","DOI":"10.1006\/bbrc.2002.6355"},{"key":"e_1_2_7_9_2","doi-asserted-by":"publisher","DOI":"10.1507\/endocrj.49.417"},{"key":"e_1_2_7_10_2","doi-asserted-by":"publisher","DOI":"10.1210\/en.2004-0129"},{"key":"e_1_2_7_11_2","doi-asserted-by":"publisher","DOI":"10.1210\/en.136.12.5547"},{"key":"e_1_2_7_12_2","doi-asserted-by":"publisher","DOI":"10.1152\/ajpcell.1999.276.4.C955"},{"key":"e_1_2_7_13_2","doi-asserted-by":"publisher","DOI":"10.1530\/eje.0.1400468"},{"key":"e_1_2_7_14_2","doi-asserted-by":"publisher","DOI":"10.1006\/bbrc.1999.0718"},{"key":"e_1_2_7_15_2","doi-asserted-by":"publisher","DOI":"10.1677\/joe.0.1710349"},{"key":"e_1_2_7_16_2","doi-asserted-by":"publisher","DOI":"10.1038\/oby.2004.84"},{"key":"e_1_2_7_17_2","doi-asserted-by":"crossref","first-page":"2367","DOI":"10.1210\/endo.134.6.8194462","article-title":"Anorectic effects of estrogen may be mediated by decreased neuropeptide\u2010 Y release in the hypothalamic paraventricular nucleus","volume":"134","author":"Bonavera J.
