Abstract

The timely secretion of gonadal sex steroids is essential for the initiation of puberty, the postpubertal maintenance of secondary sexual characteristics and the normal perinatal development of male external genitalia. Normal gonadal steroid production requires the actions of the pituitary-derived gonadotropins, luteinizing hormone and follicle-stimulating hormone. We report four human pedigrees with severe congenital gonadotropin deficiency and pubertal failure in which all affected individuals are homozygous for loss-of-function mutations in TAC3 (encoding Neurokinin B) or its receptor TACR3 (encoding NK3R). Neurokinin B, a member of the substance P-related tachykinin family, is known to be highly expressed in hypothalamic neurons that also express kisspeptin, a recently identified regulator of gonadotropin-releasing hormone secretion. These findings implicate Neurokinin B as a critical central regulator of human gonadal function and suggest new approaches to the pharmacological control of human reproduction and sex hormone-related diseases.

  • Two of the most important excitatory components of the GnRH network were identified with the demonstration that the genetic loss of such inputs results in failure to initiate the GnRH pulse generator at the expected time of puberty, resulting in isolated hypogonadotropic hypogonadism.

  • In 2009, Topaloglu and colleagues identified NKB as an important factor for human puberty initiation, studying ten consanguineous families with multiple affected members who had isolated hypogonadotropic hypogonadism.

  • Homozygous loss-of-function mutations in the genes encoding the NKB receptor (TACR3) and neurokinin B (TAC3) were identified, providing compelling evidence that the NKB system is necessary for the activation of the hypothalamic-pituitary-gonadal axis in puberty.

    From Pubertal development and regulation (2016) · cites this paper as [44]

  • Although studies in animals have led to identification of regulators of GnRH such as catecholamines, GABA, and glutamate, genetic studies of patients with pubertal disorders have resulted in the identification of a major regulatory hub for the GnRH neurons-ie, the hypothalamic neurons expressing kisspeptin and neurokinin B.

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.
