A cytochrome P450 monooxygenase involved in the metabolism of steroid hormones and vitamins during embryogenesis. Mechanistically, uses molecular oxygen inserting one oxygen atom into a substrate, and reducing the second into a water molecule, with two electrons provided by NADPH via cytochrome P450 reductase (NADPH--hemoprotein reductase). Catalyzes the hydroxylation of carbon-hydrogen bonds. Metabolizes 3beta-hydroxyandrost-5-en-17-one (dehydroepiandrosterone, DHEA), a precursor in the biosynthesis of androgen and estrogen steroid hormones. Exhibits high catalytic activity for the formation of hydroxyestrogens from estrone (E1), particularly D-ring hydroxylated estrone at the C16-alpha position. Mainly hydroxylates all trans-retinoic acid (atRA) to 4-hydroxyretinoate and may play a role in atRA clearance during fetal development. Also involved in the oxidative metabolism of xenobiotics including anticonvulsants.内毒素:

At least two cytochromes P450 belonging to the CYP3A subfamily may be expressed in adult human liver (1 ), CYP3A4 and CYP3A5. A third enzyme, CYP3A7, is expressed in human fetal liver (2 ). The CYP3A enzymes account for an estimated ~30
代谢中的 I 相药酶(CYP)活性,具有研究价值。而人胎肝细胞只能表达微量的 CYP1A1 和 CYP3A7。此外,来源于人的肝肿瘤细胞株,如 HepG2,具有肝细胞的一些基本功能,如含有 CYP450 的一些酶(如 CYP2E1、1A1 等),也可用于 CYP 诱导、基因的表达及药物代谢机理的研究。然而,人原代肝细胞来源稀少,生命周期和生长活性有限,即使改进培养方法,采用三明治夹心培养法,都会随培养时间增加,难以维持和体内一致的 CYP 酶系,使肝细胞对受试物的反应能力迅速下降。此外,人肝细胞
