一般說明
25-羟基胆固醇（25HC）在氧气和胆固醇 25-羟化酶存在下由胆固醇合成，并且在 toll 样受体激活过程中转化依赖于烟酰胺腺嘌呤二核苷酸磷酸（NADPH）。25HC 分解代谢为 7α-羟基化甾醇。25-羟基胆固醇-d6 是 25-羟基胆固醇的氘代形式。
應用
25-羟基胆固醇-d6 在以下反应中用作内标：
- 通过液相色谱和串联质谱（LC-MS-MS） 法对空肠样品中的 25-OHC 进行定量
- 通过液相色谱-质谱法分析在血浆样品中
- 用于生成血浆氧甾醇定量的校准曲线
生化／生理作用
25-羟基胆固醇是一种肝脏 X 受体配体。这种生物活性脂质调节免疫反应和单核细胞的巨噬细胞产生。25-HC 作为抗病毒效应物，可能具有治疗潜力。它通过使甾醇调节元件结合蛋白失活并抑制 HMG-CoA 还原酶（HMGCR） 来减少胆固醇的生物合成。25-HC 可能通过抑制细胞凋亡和调节丝裂原活化蛋白激酶（MAPK） 通路在心肌缺血再灌注损伤中发挥保护作用。

Cholesterol 25-hydroxylase (CH25H) catalyzes the production of 25-hydroxycholesterol (25-HC), an oxysterol that can play an important role in different biological processes. However, the mechanisms regulating CH25H expression have not been fully elucidated. In this study, we determined that CH25H is

Low-grade inflammation is constitutive of atherosclerosis, and anti-inflammatory therapy inhibiting interleukin-1β (IL-1β) reduces the rate of cardiovascular events. While cholesterol accumulation in atheroma plaque and macrophages is a major driver of the inflammatory process, the role of the LXR cholesterol
