2020年1月1日 · This chapter discusses different aspects of the PBG axis of South American teleosts, including the morphology of the pituitary gland, gonads, and gametes; the development of gametes throughout the reproductive cycle; and the hormonal control of gametogenesis.

The aims of this study were to provide transcript data and genes related to the BPG axis, and to characterize the expression profiles of ovarian steroidogenesis-related genes in the Japanese sardine (Sardinops melanostictus, Clupeidae).

2020年9月29日 · The endocrine system along with the brain–pituitary–gonadal (BPG) axis is critical for regulating reproduction. The aims of this study were to provide transcript data and genes related to the BPG axis, and to characterize the expression profiles of ovarian steroidogenesis-related genes in the Japanese sardine (Sardinops melanostictus ...

2015年12月7日 · We show that photoperiod regimes affect the brain mRNA expression of circadian and reproductive axis related genes prior to the activation of the endocrine BPG axis, suggesting that puberty onset requires coordination and possibly co-regulation of …

The key component regulating vertebrate puberty and sexual maturation is the endocrine system primarily effectuated along the brain-pituitary-gonad (BPG) axis. By far most investigations on the teleost BPG axis have been performed on salmonids, carps, catfish and eels.

2024年7月5日 · 通过体内研究，探讨了雌激素（E2）和雄激素（T）对未发育卵巢的鳗鱼脑-垂体-性腺（BPG）轴中促性腺激素释放激素（GnRH）和促性腺激素（GtH）的反馈调节作用。 然而，BPG轴的调控作用仅在卵巢发育的洄游阶段才变得明显。 为了进一步阐明BPG轴的直接反馈调控，雌性鳗鲡接受了卵黄发生的人工诱导，并通过体外暴露探讨了GtH（人绒毛膜促性腺激素，hCG）、E2和T对BPG轴组织的调控。 分别测定了GnRH（mGnRH）、GtH（fshb和lhb） …

2020年1月1日 · The brain-pituitary-gonadal axis (BPG-axis) plays an important role in gametogenesis in teleosts as well as in other vertebrates, according to data well established in the literature.

2006年1月1日 · The rapid expansion of endocrine research has provided key insights into the normal functioning of the fish brain–pituitary–gonad (BPG) axis, permitting development of more complex and biologically accurate computational models.

To better understand the complexity of the brain-pituitary-gonad axis (BPG) in fish, we developed a biologically based pharmacodynamic model capable of accurately predicting the normal functioning of the BPG axis in salmon. This first-generation model consisted of a set of 13 equations whose formula …

2004年3月1日 · The key component regulating vertebrate puberty and sexual maturation is the endocrine system primarily effectuated along the brain–pituitary–gonad (BPG) axis. By far most investigations on the teleost BPG axis have been performed on …
