Corticotropin–releasing factor receptors in human pituitary gland: autoradiographic localization

De Souza, Errol B., Perrin, Marilyn H., Whitehouse, Peter J., Rivier, Jean, Vale, Wylie, Kuhar, Michael J.·2008·Neuroendocrinology

Abstract

Corticotropin-releasing factor (CRF) receptors were localized in the human pituitary gland by an in vitro labeling light microscopic autoradiographic technique using an 125I-labeled analog of ovine CRF substituted with norleucine and tyrosine at amino acid residues 21 and 32, respectively. Specific binding sites for CRF were observed in the anterior lobe while no specific binding sites for CRF were present in the posterior pituitary lobe. The CRF binding sites in the anterior lobe occurred in clusters which predominated in the anteromedial portion of the lobe. This pattern of localization of CRF binding sites resembles previously reported distributions of corticotrophs in anterior pituitary. These data support the physiological role of endogenous CRF in regulating hormone secretion from the anterior lobe of the human pituitary.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Both CRH and AVP act on their own receptors on corticotrope cells in the anterior pituitary to stimulate ACTH production and release, with different or even similar potencies.

    “Namely, it has been indicated that both CRH and AVP act on their own receptors (28–32) on corticotrope cells in anterior pituitary to stimulate adrenocorticotropic hormone (ACTH) production and release with different (26, 33–41) or even similar potencies (42).”

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.
