Steroid Hormones and Leiomyomas
Obstetrics and Gynecology Clinics of North America, 2006The sex steroid hormones play an important role in myoma maintenance and growth as evidenced by clinical, molecular, biological, and pharmacological models. It is hoped that the next phase of research will elucidate better the mechanisms through which these hormones modulate myoma growth and how they interact with the as yet unidentified other factors ...

Abstract The anti-sickling activities of testosterone and progesterone were investigated by administering these agents by injection to 6 patients, 2 with sickle cell anaemia and 4 with sickle cell trait. No change in the in vitro sickling phenomenon was demonstrated.

Brain-derived neurotrophic factor (BDNF) is a neurotrophin abundantly expressed in several areas of the central nervous system (CNS) and is known to induce a lasting potentiation of synaptic efficacy, to enhance specific learning and memory processes.

THE LIVER AND STEROID HORMONES
Medical Journal of Australia, 1977In this issue of the Journal 2 reports of single cases of hepatocellular carcinoma are reported. Contraceptive steroids were associated with 1 and androgens with the other. Benign hepatomas have been produced in rats only after 2 years administration of doses 50-6250 times the human oral contraceptive dose.

After a brief survey of the literature on the recently discovered brassinolide, some of our results with corticosteroids are given. A number of structural requirements of corticosteroids were deduced in a bioassay involving elongation growth and lateral root formation. To explain the activity of glucocorticoids, the involvement of a receptor protein is

STEROID HORMONES AND THEIR RECEPTORS
Journal of Endocrinology, 1973Abstract INTRODUCTION It is believed that in target tissues steroid hormones are bound by cytoplasmic receptors* of high affinity and specificity; that the steroid receptor complex moves to the nucleus where physiological changes are initiated via a modification of genetic ...

Profiling steroid hormones and urinary steroids
Journal of Chromatography B: Biomedical Sciences and Applications, 1986This paper reviews techniques utilized in the profiling of steroids in body fluids and tissues. Methods for profiling plasma unconjugated steroids and urinary steroid metabolites are focused on. Concentrations or levels of excretion of a variety of steroids have been documented and reviewed. The importance of profiling techniques in the study of normal

Gene Regulation by Steroid Hormones
Cell, 1989The ability of cells to specify the fraction of their genetic information that they express in a particular spatiotemporal context is essential for adaptation to the changing conditions of their surroundings. In higher organisms, cells must respond to stimuli from the outer world and to signals from other cells directed to coordinate their state of ...

MECHANISM OF ACTION OF STEROID HORMONES
Journal of Steroid Biochemistry, 1975Despite the diversity in the target sites and physiological actions of the steroids, an impressive body of evidence has been assembled in support of a unitary theory of the mechanism of action of these hormones in vertebrates. The steroids set in motion a train of events, as follows: (a) penetration into the target cell, (b) stereo specific binding to ...
