TLDR
In vitro, dopamine faithfully mimicked the effect of progesterone by causing a translocation of chicken progestersone receptor (cPR) from cytoplasm to nucleus, and a serine residue in the cPR was identified that is not necessary for progester one-dependent activation of cPR, but is essential for dopamine activation of this receptor.Abstract:
The current view of how steroid hormone receptors affect gene transcription is that these receptors, on binding ligand, change to a state in which they can interact with chromatin and regulate transcription of target genes. Receptor activation is believed to be dependent only on this ligand-binding event. Selected steroid hormone receptors can be activated in a ligand-independent manner by a membrane receptor agonist, the neurotransmitter dopamine. In vitro, dopamine faithfully mimicked the effect of progesterone by causing a translocation of chicken progesterone receptor (cPR) from cytoplasm to nucleus. Dual activation by progesterone and dopamine was dissociable, and a serine residue in the cPR was identified that is not necessary for progesterone-dependent activation of cPR, but is essential for dopamine activation of this receptor.read more

The protective effects of estrogen on the cardiovascular system
TL;DR: Estrogen has direct and indirect effects on the cardiovascular system that are mediated by the estrogen receptors ER-alpha and ER-beta, and indirectly influences serum lipoprotein and triglyceride profiles, and the expression of coagulant and fibrinolytic proteins.

TL;DR: The role of estrogen receptors in physiology and pathology has been investigated in the past decade and it was found that there was not one but two distinct and functional estrogen receptors, now called ERα and ERβ.

TL;DR: This review presents the major advances in knowledge of the molecular mechanisms of TH action and their implications for TH action in specific tissues, resistance to thyroid hormone syndrome, and genetically engineered mouse models.

TL;DR: A historical perspective on a body of steroid receptor research dealing with the structure and physiological significance of the untransformed 9S receptor is provided, and it is shown that hsp90 itself exists in a variety of native multiprotein heterocomplexes independent of steroid receptors and other 'substrate' proteins.

TL;DR: Results provide direct support for progesterone's role as a pleiotropic coordinator of diverse reproductive events that together ensure species survival.

DNA sequencing with chain-terminating inhibitors
TL;DR: A new method for determining nucleotide sequences in DNA is described, which makes use of the 2',3'-dideoxy and arabinon nucleoside analogues of the normal deoxynucleoside triphosphates, which act as specific chain-terminating inhibitors of DNA polymerase.

The steroid and thyroid hormone receptor superfamily
TL;DR: A superfamily of regulatory proteins that include receptors for thyroid hormone and the vertebrate morphogen retinoic acid is identified, suggesting mechanisms underlying morphogenesis and homeostasis may be more ubiquitous than previously expected.

TL;DR: A series of recombinant genomes which directed expression of the enzyme chloramphenicol acetyltransferase (CAT) in mammalian cells provided a uniquely convenient system for monitoring the expression of foreign DNAs in tissue culture cells.

TL;DR: Pharmacological and biochemical criteria can be used to separate those dopamine receptors which are linked to the enzyme adenylyl cyclase and those which are not.
Journal ArticleDOI
Gene regulation by steroid hormones.
TL;DR: The location, orientation, and structure of the hormone regulatory elements (HRE) in nine hormonally modulated genes is described and a model for the interaction is proposed in which a dimer of the receptor in head-to-head orientation binds to the inverted symmetry element of the HRE.
