Abstract

Mammalian reproductive cycles are controlled by an intricate interplay between the hypothalamus, pituitary and gonads. Central to the function of this axis is the ability of the pituitary gonadotrope to appropriately respond to stimulation by gonadotropin-releasing hormone (GnRH). This review focuses on the role of cell signaling and in particular, mitogen-activated protein kinase (MAPK) activities regulated by GnRH that are necessary for normal fertility. Recently, new mouse models making use of conditional gene deletion have shed new light on the relationships between GnRH signaling and fertility in both male and female mice. Within the reproductive axis, GnRH signaling is initiated through discrete membrane compartments in which the receptor resides leading to the activation of the extracellular signal-regulated kinases (ERKs 1/2). As defined by gonadotrope-derived cellular models, the ERKs appear to play a central role in the regulation of a cohort of immediate early genes that regulate the expression of late genes that, in part, define the differentiated character of the gonadotrope. Recent data would suggest that in vivo, conditional, pituitary-specific disruption of ERK signaling by GnRH leads to a gender-specific perturbation of fertility. Double ERK knockout in the anterior pituitary leads to female infertility due to LH biosynthesis deficiency and a failure in ovulation. In contrast, male mice are modestly LH deficient; however, this does not have an appreciable impact on fertility.

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

  • The resultant phenotype of pituitary-specific ERKdko was female-specific anovulatory infertility due to loss of LH β subunit expression resulting in inability to mount a preovulatory surge of LH.

    “The resultant phenotype was female-specific anovulatory infertility due to a loss of luteinizing hormone (LH) β subunit expression resulting in an inability to mount a preovulatory surge of LH.”
  • In past studies, a pituitary-specific conditional ERK double knockout (ERKdko) was reported using ERK1 null and ERK2 floxed alleles combined with αGSU-Cre and GRIC drivers.

    “In past studies, we reported a pituitary-specific conditional ERK double knockout (ERKdko) using the ERK1 null and ERK2 floxed alleles combined with a Cre recombinase driver regulated by the gene promoter for the α subunit to the glycoprotein hormones (αGSU)3,4 and the gonadotrope-specific Cre driver (GRIC)12,13.”

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.
