Transcription profiling of rat fetal kidney samples from offspring of hyperinsulinemic mothers


ABSTRACT: 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

In humans, intrauterine growth-restricted newborns are prone to develop hypertension as adults. We studied a rat model of pregnancy-induced hypertension associated with intrauterine growth restriction (IUGR) produced by chronic administration of insulin. Fetuses of hyperinsulinemic dams (HDs) were smaller than those of normal dams (5.1+/-0.4 g versus 5.6+/-0.1 g, respectively; P<0.05). At 16 weeks of age, tail-cuff systolic blood pressure was measured, the rats were placed in metabolic cages and  ...[more]
