Abstract

Living organisms detect seasonal changes in day length (photoperiod) [1-3] and alter their physiological functions accordingly to fit seasonal environmental changes. TSHβ, induced in the pars tuberalis (PT), plays a key role in the pathway that regulates vertebrate photoperiodism [4, 5]. However, the upstream inducers of TSHβ expression remain unknown. Here we performed genome-wide expression analysis of the PT under chronic short-day and long-day conditions in melatonin-proficient CBA/N mice, in which the photoperiodic TSHβ expression response is preserved [6]. This analysis identified "short-day" and "long-day" genes, including TSHβ, and further predicted the acute induction of long-day genes by late-night light stimulation. We verified this by advancing and extending the light period by 8 hr, which induced TSHβ expression within one day. In the following genome-wide expression analysis under this acute long-day condition, we searched for candidate upstream genes by looking for expression that preceded TSHβ's, and we identified the Eya3 gene. We demonstrated that Eya3 and its partner Six1 synergistically activate TSHβ expression and that this activation is further enhanced by Tef and Hlf. These results elucidate the comprehensive transcriptional photoperiodic response in the PT, revealing the complex regulation of TSHβ expression and unexpectedly rapid response to light changes in the mammalian photoperiodic system.

  • Melatonin-proficient mice appear to possess a similar ability to induce eya3, suggesting that this mechanism could be evolutionarily conserved.

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.
