Corticosteroid

corticosteroidssteroidssteroid
Steroid hormones can be grouped into two classes: corticosteroids (typically made in the adrenal cortex, hence cortico-) and sex steroids (typically made in the gonads or placenta).
Corticosteroids are a class of steroid hormones that are produced in the adrenal cortex of vertebrates, as well as the synthetic analogues of these hormones.

Sex steroid

sex hormonesex hormonessex steroids
Steroid hormones can be grouped into two classes: corticosteroids (typically made in the adrenal cortex, hence cortico-) and sex steroids (typically made in the gonads or placenta).
Sex steroids, also known as gonadocorticoids and gonadal steroids, are steroid hormones that interact with vertebrate androgen or estrogen receptors.

Glucocorticoid

glucocorticoidssteroidssteroid
Within those two classes are five types according to the receptors to which they bind: glucocorticoids, mineralocorticoids (corticosteroids), androgens, estrogens, and progestogens (sex steroids).
Glucocorticoids are a class of corticosteroids, which are a class of steroid hormones.

Hormone

hormoneshormonalprohormone
A steroid hormone is a steroid that acts as a hormone.
Amino acid–based hormones (amines and peptide or protein hormones) are water-soluble and act on the surface of target cells via second messengers; steroid hormones, being lipid-soluble, move through the plasma membranes of target cells (both cytoplasmic and nuclear) to act within their nuclei.

Mineralocorticoid

mineralocorticoidsmineralcorticoidantinatriuretic agent
Within those two classes are five types according to the receptors to which they bind: glucocorticoids, mineralocorticoids (corticosteroids), androgens, estrogens, and progestogens (sex steroids).
Mineralocorticoids are a class of corticosteroids, which in turn are a class of steroid hormones.

Androgen

androgensandrogenicAndrogenic steroid
Within those two classes are five types according to the receptors to which they bind: glucocorticoids, mineralocorticoids (corticosteroids), androgens, estrogens, and progestogens (sex steroids).
An androgen (from Greek andr-, the stem of the word meaning "man") is any natural or synthetic steroid hormone that regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors.

Steroid

A steroid hormone is a steroid that acts as a hormone.
The major classes of steroid hormones, with prominent members and examples of related functions, are:

Progestogen

progestogensprogestationalgestagen
Within those two classes are five types according to the receptors to which they bind: glucocorticoids, mineralocorticoids (corticosteroids), androgens, estrogens, and progestogens (sex steroids).
Progestogens, also sometimes written progestagens or gestagens, are a class of steroid hormones that bind to and activate the progesterone receptor (PR).

Estrogen

oestrogenestrogensestrogenic
Within those two classes are five types according to the receptors to which they bind: glucocorticoids, mineralocorticoids (corticosteroids), androgens, estrogens, and progestogens (sex steroids).
Like all steroid hormones, estrogens readily diffuse across the cell membrane.

Adrenal gland

adrenal glandsadrenalsuprarenal gland
The natural steroid hormones are generally synthesized from cholesterol in the gonads and adrenal glands.
Each gland has an outer cortex which produces steroid hormones and an inner medulla.

Cholesterol

The natural steroid hormones are generally synthesized from cholesterol in the gonads and adrenal glands.
It is also a precursor molecule for all steroid hormones and vitamin D.

Sex hormone-binding globulin

SHBGsex hormone binding globulinEstradiol-binding protein
Steroid hormones are generally carried in the blood, bound to specific carrier proteins such as sex hormone-binding globulin or corticosteroid-binding globulin.
Other steroid hormones such as progesterone, cortisol, and other corticosteroids are bound by transcortin.

Steroid hormone receptor

steroid receptorglucocorticoid receptorssteroid receptors
They can pass through the cell membrane as they are fat-soluble, and then bind to steroid hormone receptors (which may be nuclear or cytosolic depending on the steroid hormone) to bring about changes within the cell.
They are generally intracellular receptors (typically cytoplasmic or nuclear) and initiate signal transduction for steroid hormones which lead to changes in gene expression over a time period of hours to days.

Cortisone

Cortisone is a pregnane (21-carbon) steroid hormone.

Estradiol

17β-estradioloestradiol17-β-estradiol
Estradiol (E2), also spelled oestradiol, is an estrogen steroid hormone and the major female sex hormone.

Nuclear receptor

nuclear receptorsnuclearmechanism
In order to be active, steroid hormones must free themselves from their blood-solubilizing proteins and either bind to extracellular receptors, or passively cross the cell membrane and bind to nuclear receptors.
In the field of molecular biology, nuclear receptors are a class of proteins found within cells that are responsible for sensing steroid and thyroid hormones and certain other molecules.

Mifepristone

Mifepristone, also known as 11β-(4-(dimethylamino)phenyl)-17α-(1-propynyl)estra-4,9-dien-17β-ol-3-one, is a synthetic estrane steroid and a derivative of steroid hormones like progesterone, cortisol, and testosterone.

Adrenal cortex
