一般描述

27-羟基胆固醇(27-HC)是由胆固醇在肝脏中的甾醇27-羟化酶作用下合成的。在0.15至0.73 μM的循环范围中,它是一种丰富的氧化甾醇。27-HC是胆汁合成的底物。27-羟基胆固醇-d6是27-羟基胆固醇的氘代形式。

应用

27-羟基胆固醇-d6已用于:
  • 心脏线粒体样品同位素稀释质谱分析中的内标物
  • 用作血浆甾醇定量的气相色谱-质谱(GC-MS)中的内标物
  • 作为用于加标血浆样品氘代内标,用于液相色谱和串联质谱(LC-MS-MS)分析

生化/生理作用

27-羟基胆固醇(27-HC)是一种弱肝X受体(LXR)激动剂和选择性雌激素受体调节剂(SERM)。在高胆固醇血症中观察到了27-HC的水平升高。27-HC与乳腺癌肿瘤和胶质母细胞瘤进展有关。27-HC可能有助于治疗非酒精性脂肪性肝炎。27-HC的水平升高与动脉粥样硬化病变相关。

Glioblastoma is the most frequent primary malignant brain tumor in adults. Oxysterols are oxidation products of cholesterol generated by enzymatic reactions. 27-hydroxycholesterol (27-HC), an oxysterol, is an abundant metabolite of cholesterol. 27-HC significantly accelerates mammary cancer growth, proliferation and progression

Oxysterols (OHC) are biologically active cholesterol metabolites circulating in plasma that may be formed enzymatically (e.g. 24S-OHC, 25-OHC and 27-OHC) or by autoxidative mechanisms (e.g. 7-ketocholesterol, 7β-OHC and 25-OHC). Oxysterols are more soluble than cholesterol and are reported to exert
