Estrogen positive feedback to gonadotropin-releasing hormone (GnRH) neurons in the rodent: The case for the rostral periventricular area of the third ventricle (RP3V)

Abstract

Increasing levels of circulating estradiol during the follicular phase of the ovarian cycle act on the brain to trigger a sudden and massive release of gonadotropin-releasing hormone (GnRH) that evokes the pituitary luteinizing hormone surge responsible for ovulation in mammals. The mechanisms through which estrogen is able to exert this potent "positive feedback" influence upon the GnRH neurons are beginning to be unravelled. Recent studies utilizing mouse models with global and cell-specific deletions of the different estrogen receptors (ERs) have shown that estrogen positive feedback is likely to use an indirect pathway involving the modulation of ERalpha-expressing neurons that project to GnRH neurons. Conventional tract tracing studies in rats, and experiments involving conditional pseudorabies virus tract tracing from GnRH neurons in the transgenic mouse, indicate that the dominant populations of ERalpha-expressing neuronal afferents to GnRH neurons reside in the anteroventral periventricular, median preoptic and periventricular preoptic nuclei. Together these estrogen-sensitive afferents to GnRH neurons form a periventricular continuum that can be referred to as rostral periventricular area of the third ventricle (RP3V) neurons. The neurochemical identity of some RP3V neurons has been determined and there is mounting evidence for important roles of glutamate, GABA, kisspeptin and neurotensin-expressing RP3V neurons in estrogen positive feedback. The definition of the key cluster of estrogen-sensitive neurons responsible for activating the GnRH neurons to evoke the GnRH surge (and ovulation) should be of substantial value to on-going efforts to understand the molecular and cellular basis of the estrogen positive feedback mechanism.

  • Evidence supports the AVPV/PeN kisspeptin role in the LH surge: Kiss1 expression is higher in females, these neurons have ERα and activate during the surge, and Kiss1 or Kiss1R knockout mice lack the surge even with E2.

    “Supporting this hypothesis, AVPV/PeN Kiss1 gene expression is greater in females than males (males do not show an LH surge), Kiss1 neurons in the AVPV/PeN express ERα and show increased neuronal activation exclusively during the LH surge, and Kiss1 knockout (KO) mice and Kiss1R KO mice do not exhibit an LH surge even with exogenous E2 treatment3,5.”

    From Emerging insights into hypothalamic‐pituitary‐gonadal axis regulation and interaction with stress signalling (2018) · cites this paper as [3]

    The “Neurochemical phenotypes of RP3V neurons” section describes a female-dominant distribution of AVPV/PVpo kisspeptin neurons, ERα expression, and c-Fos activation at the time of estrogen positive feedback. It also reports evidence that kisspeptin is required for the GnRH surge, but does not report that Kiss1 or Kiss1R knockout mice lack an LH surge despite exogenous E2 treatment. (LLM, conf=0.88)

  • GnRH cells lack ERα and AR, so other steroid-sensitive circuits upstream relay feedback to them.

    “Importantly, GnRH neurons do not express estrogen receptor α (ERα) or the androgen receptor (AR), the receptors that mediate sex steroid feedback, indicating that other sex steroid-sensitive circuits “upstream” of GnRH neurons receive and relay sex steroid feedback signals to GnRH cells3.”

    From Emerging insights into hypothalamic‐pituitary‐gonadal axis regulation and interaction with stress signalling (2018) · cites this paper as [3]

    The ‘Mechanism of estrogen positive feedback to GnRH neurons’ section states that GnRH neurons lack ERα and that ERα-expressing neurons mediate indirect estrogen feedback. It does not address whether GnRH neurons lack androgen receptors or whether upstream circuits relay androgen feedback. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • E2-induced AVPV/PeN kisspeptin expression accompanies increased neuronal activation and peptide release onto GnRH neurons to drive the preovulatory GnRH/LH surge.

    “This E2-induced expression of AVPV/PeN kisspeptin occurs with an increase in kisspeptin neuronal activation and peptide release onto GnRH neurons to drive the pre-ovulatory surge of GnRH and LH3,5.”

    From Emerging insights into hypothalamic‐pituitary‐gonadal axis regulation and interaction with stress signalling (2018) · cites this paper as [3]

    In “Neurochemical phenotypes of RP3V neurons” (page not provided), the review reports estrogen-associated kisspeptin expression, activation of kisspeptin neurons during positive feedback, and evidence for their role in the GnRH surge. It does not establish increased kisspeptin release onto GnRH neurons; the same section says the relationship between rising neuropeptide mRNA and an abrupt increase in secretion is unknown.

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.
