Project description:This SuperSeries is composed of the following subset Series:; GSE4028: Effects of diethylstilbestrol (DES) on the anterior pituitary gland of the ACI, Copenhagen and Brown Norway Rat. GSE4080: Effect of DES-treated Ept congenic rat lines on gene expression in the anterior pituitary gland. GSE4081: Expression QTL (eQTL) mapping in the anterior pituitary gland using DES-treated COPxACI F2 rats. Experiment Overall Design: Refer to individual Series

Project description:Anterior pituitary glands were isolated from 21 week old male rats treated for 12 weeks with the synthetic estrogen diethylstilbestrol (DES). 43 COPxACI F2 animals were selected based on pituitary weight phenotypic extremes: 22 highest and 21 lowest pituitary weights in our F2 population. Expression profiles were determined using Affymetrix Rat Genome 230 v. 2.0 arrays. In conjunction with genomewide genotypes available for these 43 animals, linkage analysis was done using mRNA abundance of each transcript on the array as a separate quantitative phenotype. These arrays provide a resource for expression QTL (eQTL) mapping on a genomewide level in the pituitary gland. Experiment Overall Design: 43 samples from anterior pituitary gland were analyzed. COPxACI F2 male animals were treated with DES for 12 weeks, starting at 9 weeks of age. Pituitary glands were harvested and weighed at sacrifice (21 weeks of age). The 43 samples were selected for pituitary weight phenotypic extremes: 22 highest and 21 lowest pituitary weights in our F2 population. Genomewide genotypes are available for these animals and in conjunction with the array data, genomewide expression QTL (eQTL) mapping was done.

Project description:Anterior pituitary glands were isolated from 21 week old male rats treated for 12 weeks with the synthetic estrogen diethylstilbestrol (DES). Three biological replicates were prepared for each of 4 congenic lines: Ept1, Ept2, Ept6, and Ept9. Congenic rat lines were constructed by introgressing COP alleles onto an ACI background within a given Ept locus. Expression profiles were determined using Affymetrix Rat Genome 230 v. 2.0 arrays. Comparison of congenic rats with the ACI and COP parental strains (see series GSE4028) will allow identification of genes whose expression is influenced by an estrogen-induced pituitary tumor (Ept) QTL. Experiment Overall Design: 12 samples from anterior pituitary gland were analyzed. For each of 4 congenic rat lines (Ept1, Ept2, Ept6, Ept9) there were 3 biological replicates of DES-treated male animals. Congenic animals were constructed by introgressing COP alleles onto an ACI background. This was done within the linkage interval for a given Ept locus. These congenic samples can be compared to the ACI and COP parental strains (see GSE4028) to determine expression differences due to a particular chromosomal region, or QTL.

Project description:Anterior pituitary glands were isolated from 21 week old male rats either untreated or treated for 12 weeks with the synthetic estrogen diethylstilbestrol (DES). Three biological replicates were prepared for untreated, control animals and four biological replicates were prepared for DES-treated animals. This was done for each of 3 inbred rat strains: ACI, Copenhagen, and Brown Norway. Expression profiles were determined using Affymetrix Rat Genome 230 v. 2.0 arrays. Comparisons of untreated vs. treated animals within a strain will allow identification of estrogen responsive genes. Comparisons between strains, either treated or untreated, will identify strain (i.e., genetic) differences in expression. Experiment Overall Design: 21 samples from anterior pituitary gland were analyzed. For each of 3 inbred rat strains (ACI, Copenhagen, and Brown Norway) there were 3 biological replicates of untreated, control animals, and 4 biological replicates of DES-treated animals.

Project description:Male Sprague-Dawley rats were used to establish exhausted-exercise model by motorized rodent treadmill. Yu-Ping-Feng-San at doses of 2.18 g/kg was administrated by gavage before exercise training for 10 consecutive days. Quantitative proteomics was performed for assessing the related mechanism of Yu-Ping-Feng-San.
