Project description:Inrauterine growth restriction was induced by chronic hyper insulinemia in pregnant rats and differential gene expression was studied using affymetrix rat genome RAE230A.Data was analysed using SAM. Experiment Overall Design: rna was isolated from 5 kidneys of growth restricted fetus and compared with 5 normal controls

Project description:We performed RNA microarray in a low protein diet (LPD) model of IUGR at three key time points of alveolarization process. IUGR and control rat pups had been studied for each time point considered: on postnatal day 4 (P4) before beginning of the alveolarization process, on P10, peak of alveolarization process and on P21 at the end of it. A twelve chip study using total RNA extracted from 14 whole lungs intrauterine growth restricted rat pups compared to 15 controls. RNA was extracted at three key time points of alveolarization in postnatal life. RNA was pooled by groups of 2 ou 3 before analysis.

Project description:Intrauterine growth restriction (IUGR) impairs fetal growth and development, perturbs nutrient metabolism, and increases the risk of developing diseases in the postnatal life. However, the underlying mechanisms by which IUGR affects fetuses remain incompletely understood. Here, we applied high-throughput proteomics approach and biochemical analysis to investigate the impact of IUGR on fetal liver.

Project description:The study objective was to determine differentially expressed mRNA transcripts in perirenal adipose tissue from fetal sheep that underwent sham or adrenal demedullation prior to fetal growth restriction to determine the role of catecholamines on gene expression following placental insufficiency-induced intrauterine growth restriction.

Project description:We created a rat renal congestion model and investigated the effect of renal congestion on hemodynamics and molecular mechanisms. The inferior vena cava (IVC) between the renal veins was ligated by suture in male Sprague-Dawley rats to increase upstream IVC pressure and induce congestion in the left kidney only. Left kidney congestion reduced renal blood flow, glomerular filtration rate, and increased renal interstitial hydrostatic pressure. Tubulointerstitial and glomerular injury and medullary thick ascending limb hypoxia were observed only in the congestive kidneys. Molecules related to extracellular matrix expansion, tubular injury, and focal adhesion were upregulated in microarray analysis. Renal decapsulation ameliorated the tubulointerstitial injury. Electron microscopy captured pericyte detachment in the congestive kidneys. Transgelin and platelet-derived growth factor receptors, as indicators of pericyte-myofibroblast transition, were upregulated in the pericytes and the adjacent interstitium. With the compression of the peritubular capillaries and tubules, hypoxia and physical stress induce pericyte detachment, which could result in extracellular matrix expansion and tubular injury in renal congestion.

Project description:A series of two color gene expression profiles obtained using Agilent 44K expression microarrays was used to examine sex-dependent and growth hormone-dependent differences in gene expression in rat liver. This series is comprised of pools of RNA prepared from untreated male and female rat liver, hypophysectomized (‘Hypox’) male and female rat liver, and from livers of Hypox male rats treated with either a single injection of growth hormone and then killed 30, 60, or 90 min later, or from livers of Hypox male rats treated with two growth hormone injections spaced 3 or 4 hr apart and killed 30 min after the second injection. The pools were paired to generate the following 6 direct microarray comparisons: 1) untreated male liver vs. untreated female liver; 2) Hypox male liver vs. untreated male liver; 3) Hypox female liver vs. untreated female liver; 4) Hypox male liver vs. Hypox female liver; 5) Hypox male liver + 1 growth hormone injection vs. Hypox male liver; and 6) Hypox male liver + 2 growth hormone injections vs. Hypox male liver. A comparison of untreated male liver and untreated female liver liver gene expression profiles showed that of the genes that showed significant expression differences in at least one of the 6 data sets, 25% were sex-specific. Moreover, sex specificity was lost for 88% of the male-specific genes and 94% of the female-specific genes following hypophysectomy. 25-31% of the sex-specific genes whose expression is altered by hypophysectomy responded to short-term growth hormone treatment in hypox male liver. 18-19% of the sex-specific genes whose expression decreased following hypophysectomy were up-regulated after either one or two growth hormone injections. Finally, growth hormone suppressed 24-36% of the sex-specific genes whose expression was up-regulated following hypophysectomy, indicating that growth hormone acts via both positive and negative regulatory mechanisms to establish and maintain the sex specificity of liver gene expression.
