Cholesteryl oleate is one of the most abundant lipids in the atherosclerotic plaque, which is associated with the progression of atherosclerosis [1]. Cholesteryl oleate can penetrate into the clusters composed of oleic acid dimers and decrease the rotational movements of oleic acid [2]. Cholesteryl oleate is widely used as an arterial atherosclerosis lesion model to verify the removal effect of 5.75μm free electron laser irradiation [3]. Cholesteryl oleate accumulates in prostate cancer and is significantly correlated with cancer progression, is employed as the diagnostic biomarker for prostate cancer[4]. Cholesteryl oleate has been widely used in low-toxicity cationic solid lipid nanoparticles to achieve safe and effective non-viral nucleic acid delivery[5].

Cholesteryl oleate是动脉粥样硬化斑块中含量最丰富的脂质之一，与动脉粥样硬化的进展相关[1]。Cholesteryl oleate能渗透进入由油酸二聚体组成的簇中，并降低油酸的旋转运动[2]。Cholesteryl oleate被广泛用作动脉粥样硬化病变模型，以验证5.75μm自由电子激光照射的清除效果[3]。Cholesteryl oleate在前列腺癌中积累，并与癌症进展显著相关，被用作前列腺癌的诊断生物标志物[4]。Cholesteryl oleate已被广泛用于低毒阳离子固体脂质纳米颗粒中，以实现安全有效的非病毒核酸递送[5]。
