Steroid hormone receptors an update

Sometimes tumors on the pituitary or adrenal glands can contribute to a condition known as Cushing syndrome , which is characterized by high levels of cortisol in the blood. Individuals with Cushing syndrome will experience rapid weight gain in the face, abdomen, and chest. Often doctors will notice this because of the individual's slender arms and legs compared to the heavy weight in the core of the body. Cushing syndrome also causes a flushed face, high blood pressure, and changes in the skin. Osteoporosis and mood swings are also a factor considered with Cushing disease.

steroid ster·oid (stěr'oid', stēr'-)
n.
Any of numerous naturally occurring or synthetic fat-soluble organic compounds having as a basis 17 carbon atoms arranged in four rings and including the sterols and bile acids, adrenocortical and sex hormones, certain natural drugs such as digitalis compounds, and the precursors of certain vitamins. Also called steroid hormone . adj. ste·roid·al (stĭ-roid', stě-)
Relating to or characteristic of steroids or steroid hormones.

Literature on steroid hormone receptors is reviewed. Cytosol and nuc lear estrogen receptors in the mammalian uterus, the mechanism of entry of estradiol into uterine cells, the regulation of the amount of uterine estrogen receptors, estrogen receptors in other organs and species, the chick oviduct system and progesterone receptors in the mammalian uterus, physiochemical aspects of progesterone receptors, the regulation of progesterone receptors, progesterone receptors, progesterone receptors in other organs and species, cytosol and nuclear androgen receptors in the rat ventral prostate and other organs and species, the regulation, genetic control, and plurality of androgen receptors, the distribution and ontogeny of glucocorticosteroid receptors, the relationships between cytosol and nuclear glucocorticosteroid receptors, mineralocorticosteroid receptors in the rat kidney and other organs and species, receptors of ecdysone, Vitamin-D and thyroid hormone, characteristics of receptor transformation, the nuclear receptor and fate of the receptor and hormone in target cell nuclei, the dependence of human cancers on hormones, the detection and characterization of steroid receptor interactions, and the physiological and pharmacological implications of steroid hormone receptors are discussed.

Biosynthesis of steroid hormones requires a battery of oxidative enzymes located in both mitochondria and endoplasmic reticulum. The rate-limiting step in this process is the transport of free cholesterol from the cytoplasm into mitochondria. Within mitochondria, cholesterol is converted to pregnenolone by an enzyme in the inner membrane called CYP11A1. Pregnenolone itself is not a hormone, but is the immediate precursor for the synthesis of all of the steroid hormones. The following table delineates the enzymes required to synthesize the major classes of steroid hormones.
