Thyroid Hormones, Gonadal and Adrenocortical Steroids and the Function of the Islets of Langerhans [PDF]

Endocrine Reviews, 1984
Thyroid hormones, gonadal and adrenocortical steroids, are glucoregulatory hormones. Thyroid hormones increase the provision of glucose to meet the enhanced energy demands which they impose. Glucose tolerance is decreased, associated with increased hepatic glucose production, although the glucose-raising effects of thyroid hormones are partially offset

Studies on the Regulation of the Onset of Steroid Hormone Biosynthesis in Fetal Rabbit Gonads* [PDF]

Endocrinology, 1979
Two aspects of the differentiation of the fetal rabbit gonad have been studied. First, the ability of the fetal ovary to synthesize 17β-estradiol from [7-3H]pregnenolone was measured. By day 18 of gestation, the fetal ovary was capable of synthesizing 17β-estradiol from radioactive pregnenolone (5 mol 2 h-1 mg protein-1), thus establishing that from ...

Gonadal Steroid Hormones and Hypothalamic Opioid Circuitry

Hormones and Behavior, 1994
Endogenous opioid peptides derived from several gene families are localized within hypothalamic regions known to be involved in the regulation of reproduction. For example, the proenkephalin gene products, met- and leu-enkephalin, and the proopiomelanocortin (POMC) gene product, beta-endorphin, are found in the rat medial preoptic area (MPOA). Moreover,

Regulation of Growth Hormone Action by Gonadal Steroids

Endocrinology and Metabolism Clinics of North America, 2007
Sex steroids modulate growth hormone (GH) secretion and action. Estrogen attenuates GH action in a dose- and route-dependent manner by inhibiting GH-regulated endocrine function of the liver. Testosterone amplifies the metabolic action of GH while exhibiting similar but independent effects of its own. The strong modulatory effect of gonadal steroids on

Gonadal Steroid Hormone Receptors and Social Behaviors [PDF]

, 1989
In this chapter, we shall discuss one aspect of the cellular mechanism of action of steroid hormones on social behaviors, the role of steroid hormone receptors. Unfortunately, the study of cellular mechanisms of hormones is not compatible with many social behaviors.
