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:Aging is a multifactorial process with significant functional alterations of the human body including endocrinal systems which control the whole-body physiology and metabolism. In this vein, aging-induced decline of endocrine function are associated with multiple physiological and metabolic diseases. However, aging-associated molecular shifts in the pituitary gland, the central organ of the endocrine system, have not been dissected systemically. In this study, we conducted single-cell transcriptomic analysis of the anterior pituitary gland by comparing old and young male mice. Single-cell transcriptomics not only increased the resolution for clustering of various cell types in the pituitary gland, but also enabled detailed analysis of differential expression and intercellular communication caused by aging. In summary, our study constructed the first single-cell transcriptomic atlas of pituitary aging and identified associated features of in a single-cell level, providing resources to develop novel potential therapeutic targets for aging-associated endocrine dysfunction.

Project description:Enhanced nutrition during the early calfhood period has been shown to hasten the onset of puberty in bull calves. The hypothalamic-pituitary-ovarian biochemical signalling axis regulates reproductive development in bulls, with the dynamics of gonadotropin pulsatility within the anterior pituitary gland, in particular, central to final sexual maturity. However, the precise molecular mechanisms regulating the influence of metabolic status on this signalling axis in bull calves is yet to be fully elucidated. The objective of this study was to determine the effect of an enhanced plane of nutrition during early life, up to 12 weeks of age, on the anterior pituitary gland proteome of bull calves. Bull calves were offered either a high or moderate plane of nutrition.

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).

Project description:The anterior pituitary gland plays central roles in body growth, reproduction, metabolism and the stress response. In this study, we performed single-cell RNA-sequencing (scRNA-seq) of 4,113 individual cells from human fetal pituitaries. We characterized divergent developmental trajectories with distinct transitional intermediate states in five hormone-producing cell lineages. Furthermore, we characterized the cellular heterogeneity of pituitary stem cells, identifying a hybrid epithelial/mesenchymal state and an early-to-late state transition. These analyses define a single-cell resolution roadmap for human pituitary development.

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.
