Steroid Hormone Regulation of Implantation
Steroid hormones Estrogen (E) and Progesterone (P) coordinate to regulate the process of embryo implantation, the process by which embryo attaches to the uterine epithelium. The uterus in response to the implanting embryo undergoes various changes to help create a suitable environment for the …

Steroid hormone regulation of fetal mouse oocyte development
… cells to form primordial follicles. Steroid hormones have been shown by numerous studies to be one of the important factors which critically govern the process of</p> <p>cyst breakdown and follicle formation. There has been earlier evidence from this laboratory to indicate that exogenous …

Hormone Regulation of NPY Neuron Activity in the Arcuate Nucleus of the Hypothalamus
… signals of energy stores, including the hormones leptin, insulin, and ghrelin, and integrate those signals with inputs from other brain regions including serotonergic neurons from the dorsal raphe. These inputs modify both long-term changes in gene transcription and acute changes in the …

Ovarian and Growth Hormone Regulation of Mammary Growth and Transcript Abundance in Prepubertal Dairy Heifers
Ovarian secretions and growth hormone (GH) are major endocrine regulators of mammary growth and development in bovine mammary gland; but information on endocrine regulation during early prepubertal period is limited. Our overall objective was to study the regulation of mammary growth and …

Mechanisms of Growth Hormone Regulation of Insulin-Like Growth Factor-I Gene Expression in Liver
… was to understand the mechanims by which growth hormone (GH) regulates insulin-like growth factor-I (IGF-I) gene expression in liver. Previous studies have suggested that GH regulation of IGF-I gene expression in liver is mediated by binding of the transcription factor signal transducer and …

Human Gonadotropin-Releasing Hormone (hGnRH) Gene Expression and Hormone Regulation in Human Placental JEG-3 Cells
… of the tissue-specific expression and steroid hormone regulation of the hGnRH gene in the human placenta. The results showed that all of the previously identified four elements are required for the full activity of the hGnRH upstream promoter in JEG-3 cells, while the element 4 (FP4, −987/−968) …

Developmental and Growth Hormone Regulation of the Expression of Liver-Enriched Transcription Factors in Bovine Liver
… during development and is affected by growth hormone (GH). These changes in gene expression may be due to the differential expression of the liver-enriched transcription factors (LETFs). To study the potential involvement of LETFs in the regulation of gene expression in the bovine liver, we …

Tissue-Specific Expression and Steroid Hormone Regulation of Human Gonadotropin -Releasing Hormone (hGnRH) Gene in Placental Cells (JEG -3 cells)
… the tissue-specific expression and steroid hormone regulation of the hGnRH gene in the human placenta. The hGnRH upstream promoter was found to be functionally active in JEG-3 cells. The DNA sequence responsible for functioning of the upstream promoter in JEG-3 cells is narrowed to a region …

Cloning and Estrogen Regulation of the Retinol Binding Protein Messenger-Rna of Xenopus Laevis
… is studying the mechanisms by which the hormone, estrogen, regulates gene expression in the frog, Xenopus laevis. In this thesis, I described the isolation of a full length cDNA clone for an estrogen induced mRNA isolated from the liver of Xenopus laevis. By DNA sequencing and subsequent …

Reproductive Biology of the Bonnethead (Sphyrna tiburo) from the Southeastern U.S. Atlantic Coast
… of this study aimed to understand gonadal sex hormone regulation in S. tiburo reproduction with a particular focus on female sperm storage. Circulating plasma sex hormones increased in association with specific reproductive events. Plasma 17β-estradiol and testosterone concentrations increased …

Genetic regulation of maize floral development - insights from the transcriptome and translatome
… gene expression. Understanding gene expression regulation in maize floral development is critical to regulate floret fertility in other grasses and potentially useful to engineer more productive cereal crops. In this work, I focus on gene expression regulation at transcriptome and translatome …

Analysis of the Role of the Transcription Factor-C/ebpbeta in Implantation
… the concerted actions of the maternal steroid hormones, estrogen and progesterone, promote a unique process known as decidualization, which involves extensive proliferation and differentiation of uterine stromal cells. The molecular pathways underlying this hormonally induced cellular …

Genetic, environmental and life-style effects on androgen receptor function
… and tissue; and reproductive parameters and hormones in men. It was also elucidated whether the CAG number could modify the effect of cigarette smoking on reproductive characteristics in men. The transactivation assay included a reporter gene with a human androgen responsive promoter. Cells …

Estrogen signaling during decidualization
… in nourishing the developing embryo. Steroid hormones estrogen (E) and progesterone (P) acting through their cognate nuclear receptors critically modulate this maternal-fetal interaction that entails the initial success of procreation. While E is primarily involved in cell proliferation and …

Discovery, Characterization, and Functional Analysis of micro RNAs in Culicidae
… RNAs that often play a fundamental role in gene regulation. Currently, hundreds to over a thousand miRNAs are predicted to be present in many eukaryote species, with many to be discovered; the functions of most are unknown. While much attention has gone towards model organisms, a much greater …

Identification of a gene that makes-plants-gigantic-1: characterization of mpg1, a novel mutant of rice
… defoliation response, cell wall metabolism, and hormone regulation. Identification of the mechanism(s) responsible for the increased biomass, seed yield, and degrees of stress tolerance may lead to strategies that could be applied to other plants to aid in both energy and food security alike.

The Inactivation of Neurohypophyseal Hormones by the Toad Bladder
… prepared. Incubation of this fraction with the hormones, oxytocin, arginine vasopressin, lysine vasopressin, and oxytocin ring amide caused their inactivation. The decrease in hormone activity was roughly exponential with the time of incubation. The hormone inactivating activity of the …
