Toxicodynamics into awareness by Our Stolen Future by Theo Colborn. Endocrine disrupting chemicals are known to accumulate in body tissue and are highly persistent in the environment. Many toxicants are known EDCs including pesticides, phthalates, phytoestrogens, some industrial/commercial products, and pharmaceuticals. These chemicals are known to cause endocrine disruption via a few different mechanisms. While the mechanism associated with the thyroid hormone receptor is not well understood, two more established mechanisms involve the inhibition of the androgen receptor and activation of the estrogen receptor. Certain toxicants act as endocrine disruptors by interacting with the androgen receptor. DDE is one example of
Multiple endocrine neoplasia mutation or hereditary transmission. The presence of two or more tumor types in a single patient does not automatically designate that individual as having MEN because there is a small statistical chance that development of two "sporadic" tumors that occur in one of the MEN syndromes could occur by chance. The term "multiple endocrine neoplasia" was introduced in 1968, but descriptions of the condition date back to 1903. Multiple endocrine neoplasia The term multiple endocrine neoplasia (MEN) encompasses several distinct syndromes featuring tumors of endocrine glands, each with its own characteristic pattern. In some cases, the tumors are malignant, in
