什么是黄体酮?

黄体酮的作用

黄体酮(黄体酮,P4,孕甾-4-烯-3,20-二酮)是一种 C-21 类固醇激素,参与人类和其他物种的女性月经周期、怀孕和胚胎发生1。 它属于一类称为孕激素的激素,是主要的天然人类孕激素2。 黄体酮是子宫、卵巢、乳腺和大脑中女性生殖功能的重要调节剂,在心血管系统、骨骼和**神经系统等非生殖组织中发挥重要作用3。

黄体酮的作用由核黄体酮受体 (PR) 的两种亚型传递:PRA 和 PRB。 PRA 和 PRB 在人、大鼠和小鼠的多种正常乳腺组织中表达,也在乳腺癌细胞中表达4,5。 黄体酮还参与周围神经系统的神经营养作用,因为它激活轴突的生长和成熟,并刺激神经纤维再生中髓鞘的修复和替换6


黄体酮的化学结构

黄体酮的代谢


在不同的动物物种中,黄体酮可以作为一种多样化和常见的黄体酮分子被代谢和排泄7。 在一些粪便中,它被发现为5-还原黄体酮(孕酮)代谢物、孕酮和氢孕酮。 这些常见黄体酮分子的测量为支持濒危物种的育种策略提供了重要数据。 使用对大多数孕酮代谢物具有高交叉反应性的群体特异性抗体有望为正在进行的生殖周期提供强有力的证据8,9
