一般說明

7α-羟基-4-胆甾烯-3-酮是胆固醇生化合成胆汁酸的中间体。其前体7α-羟基胆固醇由肝脏胆固醇7α-羟化酶(CYP7A1)从胆固醇中产生。[1]它由酶7α-羟基胆甾-4-烯-3-酮12α-羟化酶代谢为7α,12α-二羟基胆甾-4-烯-3-酮,然后再代谢为胆酸,胆酸是人类主要的原胆汁酸。或者,它可以转化为5β-胆甾烷-3α,7α-二醇,然后转化为鹅去氧胆酸,这是人类的另一种主要原代胆汁酸。血清7α-羟基-4-胆甾烯-3-酮浓度反映胆汁酸合成途径的活性。血清7α-羟基-4-胆甾烯-3-酮值在白天变化,因为胆汁酸合成速率具有昼夜节律。[2] 胆汁酸吸收不良的患者中发现升高值,这可能有助于诊断这种情况,因为高值与低SeHCAT潴留有关。[3] 血清7α-羟基-4-胆甾烯-3-酮浓度的增加反映了胆汁酸吸收不良引起的胆汁酸损失,或在原发性胆汁酸腹泻中发现的合成增加,与FGF19对CYP7A1的负反馈受损有关。[4]

應用


  • 作为胆固醇代谢介质的作用:7α-羟基胆固醇酮在关于氧固醇作为胆固醇代谢物的讨论中提及——氧固醇在生物系统中起着重要的介质作用——彰显其在胆固醇代谢中的重要性和潜在的药学价值(Mutemberezi et al., 2016)。
