Nuclear receptors and female reproduction: a tale of 3 scientists, Jensen, Gustafsson, and O'Malley.

Work on the estrogen receptor and glucocorticoid receptor laid the foundation for the discovery of a family of receptors known as the nuclear receptors. Discovery of these receptors has expanded our understanding of many hormonal and nonhormonal substances, which act through the nuclear receptors. These receptors are actually ligand-binding intracellular transcription factors, which induce nuclear expression of specific mRNAs, leading to synthesis of specific proteins with biological activity. This review for the benefit of gynecologists and reproductive physiologists focuses on the work of 3 scientists who were pioneers in the work on the estrogen, glucocorticoid, and progesterone receptors, which has had a major impact on our understanding of reproductive physiology and on the field of nuclear receptors.

[Historical foundations of the receptor concept in pharmacology]. / Historische Grundlagen des Rezeptor-Konzepts in der Pharmakologie.

In present-day pharmacology, the existence of specific cell receptors, which can combine chemically with drugs, poisons, neurotransmitters and hormones, is often taken for granted. However, until the 1960s receptors were controversial hypothetical entities. This article examines the initial experimental evidence for receptors that was produced and discussed between the 1870s and the 1930s. It is argued that pharmacologists were reluctant to adopt the receptor concept because of the indirect nature of the available experimental evidence, the competition with a physical theory of drug action and the fact that the idea of receptors had not originated from pharmacology itself, but from immunology and neurophysiology.

The jensen symposium; a tribute to a pioneer in the field of nuclear receptor biology.

The Jensen Symposium was held at the University of Cincinnati in December 2003 to honor the pioneering contributions of Dr. Elwood Jensen to the field of nuclear hormone action. Those in attendance were treated to an outstanding scientific program that served as an update of recent progress and illustrated the breadth of activity in the nuclear receptor field. Here we highlight recent findings presented at the Symposium that provide new insights into the mechanisms of nuclear receptor action and the diverse roles of members of the nuclear receptor superfamily in development and homeostasis.

Signalling through nuclear receptors.

A century ago, secretions from the pancreas were described as 'hormones', which we now know are secreted from all ductless glands. The development of various technologies has already contributed a great deal -- and will undoubtedly offer more -- to our understanding of their mode of action.
