Germ-free and anti-biotic treated rats

ABSTRACT: The objective of the study was identify hepatic genes with expression by deprivation of gut flora. Two models were used: model 1 (study 1443KR) examined germ-free Sprague Dawley and model 2 (1512KR) examined antibiotic treated Han Wistar rats.

Developmentally regulated sex differences in K48 polyubiquitination in the amygdala

Project description:This project examined if sex differences in K48 polyubiquitination in the amygdala were developmentally regulated. This used basolateral amygdala (BLA) samples collected from 4 and 9 week old male and female Sprague-Dawley rats.

Variability of gene expression profiles in neutrophils from Germ-free mice

Project description:Neutrophils, key cells of the innate immune system, are responsible for preventing bacterial infections. It was already demonstrated that albeit neutrophils synthesize lower levels of protein and RNA they are able to marked change its gene expression after bacteria exposure. The absence of microbial stimulation has consequences on development of the mucosal immune system as demonstrated using germ-free mice as a model. We are interested in understanding if commensal flora induces changes in the gene expression profile of neutrophils in its site of production, the bone marrow. Total RNA obtained from isolated neutrophils from Bone Marrow from Germ-free mice and control

Gene expression microarray analysis of early oxygen-induced retinopathy (OIR)

Project description:Different inbred strains of rats differ in their susceptibility to OIR, an animal model of human retinopathy of prematurity. We examined gene expression profiles in Fischer 344 (F344, resistant to OIR) and Sprague Dawley (SD, susceptible to OIR) rats at the early time point of day 3 to identifying gene pathways related to the underlying genetic cause of phenotypic differences between strains.

Dietary salt and renal function

Project description:Serum and glucocorticoid-induced kinase 1 (SGK1) activates the epithelial sodium channel (eNaC) in tubules. We examined renal SGK1 abundance in salt-adaptation and in salt-sensitive hypertension. Sprague-Dawley and Dahl salt-sensitive rats were placed on either 8% or 0.3% NaCl diets for 10 days. Plasma aldosterone levels were approximately 2.5-fold greater on 0.3% versus 8% NaCl diets in both rat strains. Both serum and glucocorticoid-induced kinase 1 transcript and protein abundance were less (P<0.01) in Sprague-Dawley rats and greater (P<0.01) in Dahl salt-sensitive rats on 8% versus 0.3% NaCl diets. The cDNA sequences of serum and glucocorticoid-induced kinase 1 in both strains of rat were the same. The present results provide evidence that the abundance of serum and glucocorticoid-induced kinase 1 in rat kidney may play a role in salt adaptation and the pathogenesis of hypertension and suggests that aldosterone is not the primary inducer of SGK1 in the Sprague-Dawley rat.
