动脉粥样硬化(atherosclerosis,AS)是危害人类健康的常见基础疾病,与卒中、高血压、冠状动脉疾病和糖尿病关系密切.AS以血管内膜损伤为前提,平滑肌细胞过度增殖、炎性细胞浸润、氧化应激、细胞凋亡等多种机制共同参与.在真核细胞生物中,大多数蛋白质通过泛素-蛋白酶体系统(ubiquitin-proteasome system,UPS)降解.越来越多的证据表明,UPS与AS的发生、发展及并发症的发生有关.文章对UPS与AS的关系及泛素蛋白酶抑制剂对AS的影响进行了综述.
Atherosclerosis (AS) is a common underlying disease that hazard to human health.It is closely associated with stroke,hypertension,coronary artery disease,and diabetes.AS on the premise of vascular intimnal injury,excessive smooth muscle cell proliferation,inflammatory cell infiltration,oxidative stress,apoptosis and other mschanisms participate together.In eucaryotic organisms,most proteins are degraded by ubiquitin-proteasome system (UPS).An increasing number of evidence indicates that UPS is associated with the occurrenee and development of AS and complications.This article reviews the relationship between.UPS and AS,as well as the effect of ubiquitin-proteasome inhibitor on AS.
