静脉注射胆固醇氧化酶对饮食诱导的高脂血症兔在数小时内致死,而对正常兔注射同样的酶没有明显的不良反应。这种酶的致死作用是可以解释的,因为发现注射胆固醇氧化酶处理的低密度脂蛋白会杀死正常的兔子,而没有处理的低密度脂蛋白则不会。酶氧化低密度脂蛋白也被发现对两个人细胞系和培养的牛主动脉内皮细胞具有细胞毒性。我们认为,在体内,低密度脂蛋白胆固醇到低密度脂蛋白胆固醇的酶转化可能在人类动脉粥样硬化性病变的发生中起作用。
Intravenous injection of cholesterol oxidase into hyperlipidemic rabbits in which aortic atheromatous lesions have been induced by dietary means is lethal within hours, whereas injection of the same enzyme into normal rabbits has no visible adverse effect. The lethal effect of the enzyme is explicable by the finding that injection of cholesterol-oxidase treated low-density lipoprotein kills normal rabbits, in contrast to untreated low-density lipoprotein which does not. Enzymically oxidized low-density lipoprotein was also found to be cytotoxic for two human cell lines and for cultured bovine aortic endothelial cells. We suggest that in, vivo enzymic conversion of low-density lipoprotein cholesterol to low-density lipoprotein cholestenone may possibly play a role in the initiation of atheromatous lesions in humans.
