We investigated whether leptin can suppress the prepartum activation of the fetal hypothalamus-pituitary-adrenal (HPA) axis and delay the timing of parturition in the sheep. First, we investigated the effects of a 4-day intravascular infusion of reco

Circulating Leptin Concentrations Are Positively Related to Leptin Messenger RNA Expression in the Adipose Tissue of Fetal Sheep in the Pregnant Ewe Fed at or Below Maintenance Energy Requirements During Late Gestation1

We have investigated the effects of maternal undernutrition during late gestation on maternal and fetal plasma concentrations of leptin and on leptin gene expression in fetal perirenal adipose tissue. Pregnant ewes were randomly assigned at 115 days

Abundance of leptin mRNA in fetal adipose tissue is related to fetal body weight

Autor: B. S. J. Yuen, Michael E. Symonds, Isabella Caroline McMillen, Phillip C. Owens

Publikováno v: Journal of Endocrinology. 163:R11-R14

Leptin mRNA was measured in adipose tissue of fetal sheep by reverse transcription polymerase chain reaction (RTPCR). Abundance of leptin mRNA relative to beta-actin mRNA in fetal perirenal adipose tissue increased (P

Prenatal programming of postnatal obesity : fetal nutrition and the regulation of leptin synthesis and secretion before birth

Autor: Isabella Caroline McMillen, B. S. J. Yuen, Jaime A. Duffield, Beverly S. Muhlhausler

Exposure to either an increased or decreased level of intrauterine nutrition can result in an increase in adiposity and in circulating leptin concentrations in later life. In animals such as the sheep and pig in which fat is deposited before birth, l

Leptin alters the structural and functional characteristics of adipose tissue before birth

Autor: B. S. J. Yuen, Yvonne Evens, Isabella Caroline McMillen, James R. McFarlane, Phillip C. Owens, Michael E. Symonds, Beverly S. Muhlhausler, Claire T. Roberts, K. G. Kauter, Duane H. Keisler

This study aimed to determine for the first time whether leptin can act to alter the structural and functional characteristics of adipose tissue before birth. Leptin (0.48 mg/kg/day) or saline was infused intravenously into fetal sheep for 4 days fro

Determinants of fetal leptin synthesis, fat mass, and circulating leptin concentrations in well-nourished ewes in late pregnancy

We have investigated the factors regulating leptin synthesis, fat deposition, and circulating leptin concentrations in fetuses of well nourished ewes in late pregnancy. Vascular catheters were surgically inserted in 17 pregnant ewes and their fetuses
