Hormone
(Science: endocrinology) a naturally occuring substance secreted by specialised cells that affects the metabolism or behaviour of other cells possessing functional receptors for the hormone.

The human kidney secretes two hormones:

A hormone is any chemical produced in one part of the body that has a target elsewhere in the body. Plants have five classes of hormones. Animals, especially chordates, have a much larger number.

Hormones
Most of the molecules that enable signalling between the cells or tissues within an individual animal or plant are known as "hormones." Hormone-initiated signal transduction takes the following steps: ...
hormones Chemical substances that are produced in the endocrine glands and travel in the blood to target organs where they elicit a response.
hormones: Proteins produced by organs of the body that trigger activity in other locations.
Hormone A molecule that stimulates specific cellular activity; made in one part of the body and transported via the bloodstream to tissues and organs. Examples include insulin, estrogen, and testosterone.

Hormone-binding domain A conserved 240-residue domain in members of the nuclear receptor superfamily of transcription factors that binds a hormone or hormonelike molecule, thus activating the factor.
Hormones also affect mature adults. Males and females have receptors for estrogens, progesterone, and androgens in various tissues.

A female sex hormone secreted by the corpus luteum that, in conjunction with estradiol, functions to prepare and maintain the uterine mucosa for the reception, implantation, and development of a fetus if fertilization occurs.
Human growth hormone is one of the medical products that can now be manufactured through genetic engineering. In the past, its only source was recently dead human donors. Getting human growth hormone in this way was difficult and controversial.
Human growth hormone (HGH, somatotrophin). A protein produced in the pituitary gland that stimulates the liver to produce somatomedins, which stimulate growth of bone and muscle.

Meprins cleave bioactive peptides such as gastrin, cholecystokinin and parathyroid hormone, cytokines such as osteopontin and monocyte chemotactic peptide-1, as well as proteins such as gelatin, collagen IV, fibronectin and casein.
The core tool used by the endocrine system is a compound called a hormone. Your body uses dozens of hormones to regulate your growth, digestion, body temperature, and glucose metabolism (to name a few).
Response element: By definition, a "response element" is a portion of a gene which must be present in order for that gene to respond to some hormone or other stimulus. Response elements are binding sites for transcription factors.
Diabetes mellitus is a disease characterized by an inability to make or use the hormone insulin. Insulin is needed by cells to metabolize glucose, the body's main source of chemical energy.
These glands each produce one or more hormones. These hormones are released into the bloodstream via small tubes called ducts. Once in the bloodstream, these hormones effect every cell they come in contact with, telling them to do something.
