Abstract

While the physiology of membrane-initiated estradiol signaling in the nervous system has remained elusive, a great deal of progress has been made toward understanding the activation of cell signaling. Membrane-initiated estradiol signaling activates G proteins and their downstream cascades, but the identity of membrane receptors and the proximal signaling mechanism(s) have been more difficult to elucidate. Mounting evidence suggests that classical intracellular estrogen receptor-alpha (ERalpha) and ERbeta are trafficked to the membrane to mediate estradiol cell signaling. Moreover, an interaction of membrane ERalpha and ERbeta with metabotropic glutamate receptors has been identified that explains the pleomorphic actions of membrane-initiated estradiol signaling. This review focuses on the mechanism of actions initiated by membrane estradiol receptors and discusses the role of scaffold proteins and signaling cascades involved in the regulation of nociception, sexual receptivity and the synthesis of neuroprogesterone, an important component in the central nervous system signaling.

  • These hypothalamic circuits express various ERs and use nuclear and membrane-initiated estrogen signaling.

    “These hypothalamic circuits collectively express the range of ER and employ both nuclear-initiated estrogen signaling (through estrogen response element (ERE)-dependent and ERE-independent pathways) and membrane-initiated estrogen signaling (through palmitoylated nuclear ER (α/β) and E2-responsive GPCR)34.”

    From Emerging insights into hypothalamic‐pituitary‐gonadal axis regulation and interaction with stress signalling (2018) · cites this paper as [34]

    The Introduction describes ERE-dependent and ERE-independent nuclear signaling, while Extranuclear ERα and ERβ Expression and Physiology of Membrane ERs describe membrane signaling in hypothalamic-related circuits. The Summary supports palmitoylated ERα/ERβ at membranes, but Novel ERs treats the E2-responsive GPCR candidates as uncertain rather than establishing that these circuits employ them.

  • After ligand activation, ER leaves chaperones, dimerizes, and binds coactivators or corepressors to start or stop transcription.

    “After ligand-dependent receptor activation, ER disassociates from molecular chaperones, dimerizes, and binds to coactivators or corepressors to initiate or suppress transcription34.”

    From Emerging insights into hypothalamic‐pituitary‐gonadal axis regulation and interaction with stress signalling (2018) · cites this paper as [34]

    The Introduction says that estradiol-bound intracellular ERs dimerize and recruit transcriptional machinery and cofactors to regulate gene expression. It does not say that ERs dissociate from molecular chaperones or specifically bind coactivators or corepressors to initiate or suppress transcription. No page number is available in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Nuclear ERα/ERβ signaling mainly controls gene expression by binding DNA at EREs.

    “Nuclear-initiated ERα and ERβ signaling controls gene expression primarily through direct binding to DNA via an ERE.”

  • Gonadal steroids can affect cell physiology over the long term by acting as transcription factors to regulate gene expression or rapidly through non-genomic second messenger cascades.

    “can affect cell physiology over the long term by acting as transcription factors to regulate gene expression (Heldring et al., 2007) or rapidly through non-genomic second messenger cascades (Micevych and Dominguez, 2009)”

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.
