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 …

DNA Bending by Steroid Receptors
Protein induced DNA bending is a common feature of many prokaryotic and eukaryotic DNA binding proteins and may be important in the regulation of gene transcription. Therefore, it was of interest to more clearly examine receptor-induced DNA bending and its relationship to transcriptional …

Cardiovascular consequences of anabolic steroid use
With the increase in the prevalence of anabolic steroid (AS) use for non-medical performance and image enhancement purposes, the impact of AS on cardiovascular health is an issue of growing public concern. AS use has long been associated with a number of negative CV outcomes such as acute …

Steroid induced neuroprotection of damaged photoreceptor cells
Retinitis Pigmentosa (RP) is the name given to a group of hereditary diseases causing progressive and degenerative blindness. RP affects over 1 in 4000 individuals, making it the most prevalent inherited retinal disease worldwide, yet currently there is no cure. In 2011, our group released a paper …

Steroid receptor crosstalk in breast cancer cells.
… co-treatment of breast cancer cells with corticosteroids and 17β-estadiol (E2) can have opposing effects on the proliferation of breast cancer cells compared with the single treatment. In addition, glucocorticoid receptor (GR) levels have been shown to have clinical implications for breast cancer …

Steroid Stimulated Protein Synthesis in Fish Cell Cultures
… for six hours with a 10-6 M concentration of steroid and radiolabelled with 35s-methionine for one or three hours. Testosterone produced the greatest response in CHSE-214 cells while progesterone and estrogen stimulated protein synthesis to a lesser degree. Gonad cells showed the greatest …

Steroid 2,4-Dinitrophenylhydrazones: their preparation, separation, and characterization
… (DNPH) derivatives of twelve ketonic steroids were prepared and characterized. The steroids were chosen to include adrenal, placental and testicular hormanes and metabolites of these hormones. It was found with the exception of adrenosterone-bis-DNPH that the DNPH's could be classified …

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 …

Steroid signalling in the human ovarian surface epithelium wound healing
… for hOSE. Local generation of these steroid hormones is subject to 3β-hydroxysteroid dehydrogenase (3β-HSD) activity. Moreover, action of these hormones is achieved through coupling to their cognate receptors, progesterone (PR) and androgen receptors (AR). The overall aim of this …

Steroid metabolism in the human gut by microbial hydroxysteroid dehydrogenases
Bile acids and cortisol are steroid hormones derived from cholesterol that are important signaling molecules in the human body. Bile acids are essential for nutrient solubilization and absorption in the gut while cortisol is involved in stress response and metabolism throughout the body. The gut …
