Mechanisms Underlying The Seasonal Function In Pars Tuberalis

生活在热带地区以外的动物根据光照周期的变化进行季节性繁殖。最近的研究表明，结节部（位于垂体前叶底部）在光周期时间测量中起重要作用。然而，结节部的内分泌功能尚未完全阐明。为了评估结节部在内分泌功能中的潜在作用，我们观察了眼缺失3（EYA3）的功能，因为EYA3 mRNA的表达之前在结节部以时间依赖性的方式被观察到。EYA3在结节部中的作用可能不仅是转录的共激活，而且还参与了其他一些功能。

Animals living outside the tropical region perform seasonalreproduction in accordance with changes in the photoperiod. Recent studies have demonstrated that pars tuberalis(located at the base of the anterior pituitary gland) plays an important role in photoperiodic time measurement. However, endocrine functions of the pars tuberalis have not been completely elucidated. To evaluate the potential role of the pars tuberalis in endocrine function, we observed the function of the Eyes absent 3(EYA3) since EYA3 mRNA expression was previously observed in the pars tuberalis in a time-dependent manner. The function of EYA3 in the pars tuberalis may not only be coactivation of transcription but also contribution to several other functions.
