Abstract

The hypothalamic-pituitary-adrenal (HPA) axis is activated in response to stressors and is controlled by neurons residing in the paraventricular nucleus of the hypothalamus (PVN). Although gonadal steroid hormones can influence HPA reactivity to stressors, the exact mechanism of action is not fully understood. It is known, however, that estrogen receptor β (ERβ) inhibits HPA reactivity and decreases anxiety-like behavior in rodents. Since ERβ is co-expressed with oxytocin (OT) in neurons of the PVN, an ERβ-selective agonist was utilized to test the whether ERβ decreases stress-induced HPA reactivity and anxiety-like behaviors via an OTergic pathway. Adult gonadectomized male and female rats were administered diarylpropionitrile, or vehicle, peripherally for 5days. When tested for anxiety-like behavior on the elevated plus maze (EPM), diarylpropionitrile-treated males and females significantly increased time on the open arm of the EPM compared to vehicle controls indicating that ERβ reduces anxiety-like behaviors. One week after behavioral evaluation, rats were subjected to a 20minute restraint stress. Treatment with diarylpropionitrile reduced CORT and ACTH responses in both males and females. Subsequently, another group of animals was implanted with cannulae directed at the lateral ventricle. One week later, rats underwent the same protocol as above but with the additional treatment of intracerebroventricular infusion with an OT antagonist (des Gly-NH2 d(CH2)5 [Tyr(Me)(2), Thr(4)] OVT) or VEH, 20min prior to behavioral evaluation. OT antagonist treatment blocked the effects of diarylpropionitrile on the display of anxiety-like behaviors and plasma CORT levels. These data indicate that ERβ and OT interact to modulate the HPA reactivity and the display of anxiety-like behaviors.

  • Gonadal steroids can act in a synergistic manner to decrease HPA axis gain and anxiety-related behaviors.

    “Gonadal steroids can act in a synergistic manner to decrease HPA axis gain and anxiety-related behaviors (Kudwa, McGivern, & Handa, 2014; McCarthy, McDonald, Brooks, & Goldman, 1996)”

    From Hypothalamic–pituitary–adrenal and hypothalamic–pituitary–gonadal axes: sex differences in regulation of stress responsivity (2017) · cites this paper as Kudwa, McGivern, & Handa, 2014

    The Abstract (page unavailable) reports that activating estrogen receptor β reduced anxiety-like behavior and stress-induced HPA hormone responses in gonadectomized rats. The Introduction (page unavailable) describes an interaction with an oxytocin pathway, but oxytocin is not a gonadal steroid; the paper does not establish that gonadal steroids act synergistically to produce these effects.

  • A subpopulation of parvocellular PVN OT and AVP neurons, along with ERβ and coordinating input from the BnST, is thought to be involved in the stress response, supporting the possibility that EDCs may influence the hypothalamic-pituitary-adrenal axis.

    “Finally, a subpopulation of parvocellular PVN OT and AVP neurons, along with ERβ and coordinating input from the BnST, is thought to be involved in the stress response (135, 139, 140) supporting the possibility that EDCs may influence the hypothalamic–pituitary–adrenal axis.”

  • ERβ in the PVN and associated structures, including the BnST, plays a fundamental role in mediating motivational and anxiety-related behaviors.

    “Although the functional role of limbic ERβ remains ambiguous, ERβ in the PVN and associated structures, including the BnST, plays a fundamental role in mediating motivational and anxiety-related behaviors (134–136).”

    From Endocrine Disruption of Vasopressin Systems and Related Behaviors (2017) · cites this paper as [135]

    The Introduction and Discussion (page numbers unavailable) support a role for ERβ in anxiety-like behavior and identify ERβ in the PVN. But the Discussion says the site of ERβ’s action on anxiety is unknown and names the BnST only as a possible site. The copy does not establish a fundamental role for PVN and BnST ERβ in motivational behavior. (LLM, conf=0.88)

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.
