什么是黃體酮?

黃體酮的作用

黃體酮(黃體酮,P4,孕甾-4-烯-3,20-二酮)是一種 C-21 類固醇激素,參與人類和其他物種的女性月經(jīng)周期、懷孕和胚胎發(fā)生1。 它屬于一類稱為孕激素的激素,是主要的天然人類孕激素2。 黃體酮是子宮、卵巢、乳腺和大腦中女性生殖功能的重要調(diào)節(jié)劑,在心血管系統(tǒng)、骨骼和**神經(jīng)系統(tǒng)等非生殖組織中發(fā)揮重要作用3。

黃體酮的作用由核黃體酮受體 (PR) 的兩種亞型傳遞:PRA 和 PRB。 PRA 和 PRB 在人、大鼠和小鼠的多種正常乳腺組織中表達(dá),也在乳腺癌細(xì)胞中表達(dá)4,5。 黃體酮還參與周圍神經(jīng)系統(tǒng)的神經(jīng)營(yíng)養(yǎng)作用,因?yàn)樗せ钶S突的生長(zhǎng)和成熟,并刺激神經(jīng)纖維再生中髓鞘的修復(fù)和替換6。

黃體酮的代謝


在不同的動(dòng)物物種中,黃體酮可以作為一種多樣化和常見的黃體酮分子被代謝和排泄7。 在一些糞便中,它被發(fā)現(xiàn)為5-還原黃體酮(孕酮)代謝物、孕酮和氫孕酮。 這些常見黃體酮分子的測(cè)量為支持瀕危物種的育種策略提供了重要數(shù)據(jù)。 使用對(duì)大多數(shù)孕酮代謝物具有高交叉反應(yīng)性的群體特異性抗體有望為正在進(jìn)行的生殖周期提供強(qiáng)有力的證據(jù)8,9。
