一般說明
7β-羟基胆固醇(7β-OHC)是一种氧化甾醇,由低密度脂蛋白(LDL)氧化合成。它主要在肝脏分解代谢为胆汁酸。
應用
7β-羟基胆固醇已被用于:
- 用作液相色谱-质谱(LC-MS)中的内部氧甾醇标准品,用于在抑制剂AY9944治疗后对神经球中与胆固醇生物合成相关的甾醇进行定量
- 重组高密度脂蛋白(HDL),用于胰岛素瘤细胞系INS1e中的抗凋亡研究
- 用作超高效液相色谱(UHPLC)与高分辨率四极杆飞行时间质谱(Q-TOF)联用的胆固醇氧化产物标准品
生化/生理作用
7β-羟基胆固醇(7β-OHC)通过基于半胱天冬酶8的线粒体途径促进细胞凋亡。它还通过产生活性氧(ROS)阻碍癌细胞的存活。多发性硬化症和阿尔茨海默′病(AD)患者的脑脊液中7β-OHC水平升高。7β-OHC还促进氧化凋亡和脱髓鞘。它激活丝裂原活化蛋白激酶并调节细胞内Ca2+稳态,可能有助于高尔基体和内质网膜的解体。

Some oxysterols resulting either from enzymatic oxidation or autoxidation of cholesterol are associated with age-related diseases including neurodegenerative diseases. Among these oxysterols, 7β-hydroxycholesterol (7β-OHC) is often found at increased levels in patients. It is therefore important to identify molecules or

Cholesterol and cholesterol-derived oxysterols are critical for embryonic development, synapse formation and function, and myelination, among other biological functions. Indeed, alterations in levels of cholesterol, sterol precursors, and oxysterols result in a variety of developmental disorders, emphasizing the importance of
