Membrane-Initiated Actions of Estrogens in Neuroendocrinology: Emerging Principles

Vasudevan, Nandini, Pfaff, Donald W.·2007·Endocrine Reviews

Abstract

Hormonal ligands for the nuclear receptor superfamily have at least two interacting mechanisms of action: 1) classical transcriptional regulation of target genes (genomic mechanisms); and 2) nongenomic actions that are initiated at the cell membrane, which could impact transcription.Although transcriptional mechanisms are increasingly well understood, membrane-initiated actions of these ligands are incompletely understood.Historically, this has led to a considerable divergence of thought in the molecular endocrine field.We have attempted to uncover principles of hormone action that are relevant to membrane-initiated actions of estrogens.There is evidence that the membrane-limited actions of hormones, particularly estrogens, involve the rapid activation of kinases and the release of calcium.Membrane actions of estrogens, which activate these rapid signaling cascades, can also potentiate nuclear transcription.These signaling cascades may occur in parallel or in series but subsequently converge at the level of modification of transcriptionally relevant molecules such as nuclear receptors and/or coactivators.In addition, other hormones or neurotransmitters may also activate cascades to crosstalk with estrogen receptor-mediated transcription.The idea of synergistic coupling between membrane-initiated and genomic actions of hormones fundamentally revises the paradigms of cell signaling in neuroendocrinology.(Endocrine Reviews 28: 1-19, 2007) I.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
