General description
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。
Application
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
Biochem/physiol Actions
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

In the present study, we characterize the early cytotoxic effects of 7beta-hydroxycholesterol, a major cytotoxin in oxidized LDL, in human aortic smooth muscle cells. Within a few minutes after addition, 7beta-hydroxycholesterol induced Ca(2+) oscillations with a frequency of approximately 0.3-0.4

The cytotoxic activity of 7beta-hydroxycholesterol (7beta-OHC) was evaluated on human NCI-H460 lung cancer cells. 7beta-OHC decreased clonogenic survival of NCI-H460 in a dose dependent pattern. 7beta-OHC induced apoptosis in NCI-H460, with the characteristic features like increase in sub-G(1) hypodiploid (apoptotic)
