项目摘要
CYP2B9 is a constitutively and female-specifically expressed P450 isoform in mouse livers. Hypophysectomy-induced CYP2B9 mRNA expression in males to a level similar to that in females, while the operation did not affect females. Twice-daily injection of growth hormone (GH), which mimics the male pattern of GH secretion, significantly repressed hypophysectomy-induced mRNA expression in males. The same treatment completely suppressed expression in intact females. Treatments with synthetic glucocorticoid dexamethasone (DEX) suppressed expression of CYP2B9 mRNA in intact females, but not in GH-treated and un-treated hypophysectomized females. In primary cultured mouse hepatocytes, CYP2B9 mRNA expression was concentration-dependently suppressed by natural glucocorticoids such as hydrocortisone and corticosterone as well as by DEX. Glucocorticoid-mediated suppression was partially inhibited by RU486, a potent antiglucocorticoid. In contrast, RU486 by itself suppressed expression of CYP2B9 mRNA. These observations suggest that the sexually dimorphic expression of CYP2B9 is partly due to suppression by the masculine plasma GH profile and by glucocorticoid hormones.
CYP2B9 是小鼠肝脏中组成型、女性特异性表达的 P450 亚型。垂体切除术诱导男性中 CYP2B9 mRNA 的表达水平与女性相似,而手术对女性没有影响。每天两次注射生长激素 (GH),模仿男性 GH 分泌模式,显着抑制垂体切除术诱导的男性 mRNA 表达。同样的处理完全抑制了完整雌性的表达。合成糖皮质激素地塞米松 (DEX) 治疗可抑制完整雌性中 CYP2B9 mRNA 的表达,但在 GH 治疗和未治疗的垂体切除雌性中则不然。在原代培养的小鼠肝细胞中,CYP2B9 mRNA 表达受到天然糖皮质激素(例如氢化可的松和皮质酮)以及 DEX 的浓度依赖性抑制。糖皮质激素介导的抑制可被 RU486(一种有效的抗糖皮质激素)部分抑制。相反,RU486 本身抑制 CYP2B9 mRNA 的表达。这些观察结果表明,CYP2B9 的性别二态性表达部分是由于男性血浆 GH 谱和糖皮质激素的抑制。
