Description | 7-Ketocholesterol is a metabolite of Cholesterol |
In vivo | 在心血管疾病和糖尿病患者中,7-ketocholesterol (7KC) 被认为通过介导病理性炎症来影响细胞。7KC 引起内皮细胞细胞活性的剂量依赖性下降以及凋亡和坏死的增加。同时观察到紧密连接蛋白,zonula occludens-1 (ZO-1) 和 claudin-5 向细胞核的重新定位。这些效应通过ET显著减弱。此外,7KC 显著增加了促炎细胞因子 mRNA 的表达,包括 IL-1β、IL-6、IL-8、TNF-α 和环氧合酶-2 (COX2),以及 COX2 的酶活性,而这些增加通过ET显著降低。 |
