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 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: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:ACTH is known to be secreted from pituitary cortictropes after CRH and Il-6 stimulation. Recenetly it was proven that eNampt also stimulates ACTH secretion from rat pituitary gland. We used microarrays to detail the global programme of gene expression in isolated rat pituitary corticotropes, 24h after administration of eNampt, CRH and Il-6.

Project description:The mouse pituitary gland undergoes vivid maturation immediately after birth. During this process, the local stem cell compartment shows signs of activation including elevated abundance and expression of stemness pathways when compared to adult pituitary stem cells. In addition, we found that the neonatal pituitary displays high regeneration efficiency, as occurring following diphtheria toxin (DT)-triggered endocrine cell-ablation injury using the GHCre/iDTR mouse model (expressing Cre recombinase under control of the growth hormone (Gh) promoter, as well as Cre-inducible (floxed) DT receptor (iDTR)). This regeneration is more pronounced than in older mice, which is in line with the activated (stem cell) nature of the neonatal gland. However, it is not known what molecular mechanisms underlie the stem cell activation status in the neonatal gland. Here, we set out to decode the stem cells’ phenotype during the neonatal pituitary maturation stage starting from single cell RNA-sequencing (scRNA-seq) interrogations of neonatal (postnatal day 7, PD7) normal (undamaged) and damaged pituitary (more specifically, its major endocrine anterior lobe).
