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
… pregranulosa 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 …

Steroid Hormone and Growth Factor Regulation of Peripheral Myelination
In addition to steroid hormones, signaling by platelet-derived growth factor (PDGF)-A in peripheral myelination was investigated. Lower levels of P0 were found in the developing sciatic nerve of PDGF-A null transgenic mice, especially when active myelin synthesis occurs. Morphological deformities …

Interactions of Steroid Hormone Receptors With Coactivators and DNA
II Steroid hormone receptors (HR) activate gene transcription through binding to ligands, locating specific hormone response elements (HREs) on DNA, recruiting coactivators and then chromatin remodeling complexes and ultimately the basal transcription machinery. In vivo data suggests that the …

The Effects of Vasoactive Intestinal Peptide on Adrenal Steroid Hormone Secretion
… 1984). We have studied the effects of VIP on steroid hormone secretion from the outer zones of the normal rat adrenal cortex. Intact capsule-glomerulosa preparations, consisting of the capsule, zona glomerulosa, and a small portion of the zona fasciculata were perifused in vitro. The secretory …

Hormonal modulation of sex steroid hormone receptors and oncogenes in human breast cancer cells
Since sex steroids modulate breast tumor growth, and high levels of the HER-2/neu protooncogene protein may contribute to breast cancer metastasis, the effects of estrogen, progestin and hormone antagonists on the levels of estrogen receptor (ER), progesterone receptor (PR) and HER-2/neu mRNA and …

Effect of extra-gonadal sperm depletion on steroid hormone profiles in semen of bulls
… variation and to provide adequate volume for steroid radioimmunoassay. Concentration of T and A in semen decreased significantly during depletion and reached basal concentrations. Basal concentrations were regarded as those amounts continually being produced and were considered to have been …

The acute effects of transdermal testosterone precursor administration on serum steroid hormone levels in females
… authorities have banned the use of anabolic steroids as ergogenic aids. Recently, a transdermal testosterone precursor dietary supplement (AndrosteDERMRTM) has become available; athletes can apply the cream to their skin with the belief that it will increase serum testosterone levels, muscle …

Genetic and Sex Steroid Hormone Contributions to the Sexual Dimorphism in Murine Experimental Allergic Encephalomyelitis
… susceptibility to EAE. Further, the role of sex steroid hormones and parent-of-origin effects were studied through the use of reciprocal crosses of SJL/J and BI0.S/SgMcdJ mice. We found that adult gonadal hormones selectively regulate sexually dimorphic quantitative traits observed in EAE at the …

Non-genomic control of neuronal calcium signaling by the steroid hormone estrogen leads to neuroprotective effects
… placebo controlled long-term studies, revealed hormone replacement therapy may have little, none, or detrimental effects on brain health. These studies found differences in health benefits versus risks amongst women who received hormone replacement therapy, depending on age, length of …

Tissue-Specific Expression and Steroid Hormone Regulation of Human Gonadotropin -Releasing Hormone (hGnRH) Gene in Placental Cells (JEG -3 cells)
… behind 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 …

Effects of energy and protein levels on attainment of puberty and steroid hormone production in captive female white-tailed deer
Twenty-four female fawns, weaned at 3.5 months of age, were divided into three groups and randomly assigned to one of four treatments with that group. High energy-high protein (HEHP), high energy-low protein (HELP), low energy-high protein (LEHP), and low energy-low protein (LELP) diets were the …

Development and Application of a Fluorescence Anisotropy Microplate Assay for Analyzing the Interaction of Steroid Hormone Receptors With DNA and Coactivators
… novel compounds that modulate binding of steroid receptors to their DNA response elements. Additionally, the FAMA can monitor the time course of dissociation of pre-formed steroid-receptor-DNA complexes. This feature of the FAMA has confirmed the DNA intersegment transfer model for how …

Binding sites in the nuclear envelope for cytoplasmic glucocorticoid receptor complex
… observed in the concentration range tested. Free steroid hormone did not bind the envelope. Binding sites for steroid hormones or steroid hormone-receptor complexes have been demonstrated both in chromatin and the nuclear protein matrix (Barrack and Coffey, 1980; Spelsberg, 1976). Because the …

Mapping And Characterization Of 18-5 And 12-5, Genes Which Potentially Link The Rhoa Signaling Pathway To The Ecdysone Response
Systemic steroid hormone and intracellular signaling pathways are known to act cooperatively during the development of vertebrate and invertebrate epithelia. However, the mechanism of this interaction is poorly understood. Morphogenesis of Drosophila leg imaginal disc epithelia is regulated both by …
