Endocrine disruptor

Disruption of the endocrine system can occur in various ways. Some chemicals mimic a natural hormone, fooling the body into over-responding to the stimulus, or responding at inappropriate times. Other endocrine disruptors block the effects of a hormone from certain receptors by blocking the receptor site on a cell. Still others directly stimulate or inhibit the endocrine system and cause overproduction or underproduction of hormones. Medical interventions commonly manipulate the endocrine system for the betterment of a patient, and side effe ...

The endocrine system is a control system of ductless endocrine glands that secrete chemical messengers called hormones that circulate within the body via the bloodstream to affect distant organs. It does not include exocrine glands such as salivary glands, sweat glands and glands within the gastrointestinal tract. The field of medicine that deals with disorders of endocrine glands is endocrinology, a branch of the wider field of internal medicine. Endocrine system - Physiology. The endocrine s ...

The endocrine system links the brain to the organs that control body metabolism, growth and development, and reproduction. Signal transduction of some hormones with steroid structure involves nuclear hormone receptor proteins that are a class of ligand activated proteins that, when bound to specific sequences of DNA serve as on-off switches for transcription within the cell nucleus. These switches control the development and differentiation of skin, bone and behavioral centers in the brain, as well as th ...

Diseases of the endocrine system are common, such as diabetes mellitus and thyroid disease. Endocrineopathies can occur with any of these. Hypofunction can occur as result of loss of reserve, hyposecretion, agenesis, atrophy, destruction, etc. Hyperfunction can occur as result of hypersecretion, loss of suppression, tumor, hyperplasia, etc. They are classified as primary, secondary, and tertiary. Primary is target organ dysfunction and is normally associated with increased or decreased secretory hormones. Secondary is a ...

The Congress of the United States has improved the evaluation and regulation process of drugs and other chemicals. The recent establishment of an endocrine disruptor screening program is seen as a significant step. Screening is done in vitro by examining, for instance, if an agent interacts with the estrogen receptor or the androgen receptor, and in vivo the effect of an agent can be studied in animal models, such as the uterine growth in pr ...

Endocrine systems are found in most varieties of animal life. The endocrine system is made up of glands, which secrete hormones, and receptor cells which detect and react to the hormones. Hormones are released by glands and travel throughout the body, acting as chemical messengers. Hormones interface with cells that contain matching receptors in or on their surfaces. The hormone binds with the receptor, much like a key would fit into a lock. ...
