Abstract

We examined the time course of action of GnRH pulse frequency on gonadotropin subunit gene transcription and assessed the roles of GnRH, follistatin (FS), and activin on differential transcription of the LHbeta and FSHbeta genes. GnRH-deficient male rats were pulsed with 25 ng GnRH either every 30 min (fast frequency) or every 240 min (slow frequency) for 1-24 h. Both GnRH frequencies increased alpha primary transcript (PT) 5-fold within 6 h, but only fast frequency GnRH increased alpha mRNA. Only fast frequency GnRH pulses affected LHbeta PT, resulting in 6- to 9-fold increases between 1-24 h. Fast frequency GnRH pulses transiently increased FSHbeta PT at 1 and 6 h (4- and 2-fold, respectively); but by 24 h FSHbeta PT had returned to control levels and was correlated to a 5- to 9-fold increase in FS mRNA. In contrast, slow GnRH pulses increased FSHbeta PT 3- and 6-fold at 8 and 24 h, respectively, which was correlated with a decline in FS mRNA. Activin mRNA did not change significantly after either GnRH frequency, but tended to fall after fast pulses. To test whether activin was required for the effects of GnRH on FSHbeta transcription, rats were treated with GnRH pulses every 240 min for 8 h +/- FS. FS treatment alone markedly decreased basal FSHbeta PT. GnRH in the presence of FS increased FSHbeta PT 8-fold but did not restore FSHbeta transcription to control or GnRH alone values. In summary, whereas alpha-subunit transcription is independent of frequency, an increase in a…

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.
