小檗碱抑制氧化型低密度脂蛋白诱导的人脐静脉内皮细胞增殖及其分子机制
Inhibitory effect of berberine on proliferation of human umbilical vein endothelial cells induced by oxidized low density lipoprotein and its molecular mechanism
摘要
Abstract
Aim To investigate the inhibitory effect of berberine on the proliferation of human umbilical vein endothelial cell (HUVEC) induced by oxidized low density lipoprotein (ox-LDL) and the changes of related signaling pathways.Methods HUVEC was cultured in vitro,and the proliferation of HUVEC was stimulated by ox-LDL and intervened with berberine at different concentrations.The inhibitory effect of berberine on proliferation of HUVEC was detected by cell counting kit 8 and EdU incorporation experiment.The expressions of related genes and proteins and the changes of signaling pathway were analyzed by real-time quantitative PCR and Western blot.Results In a concentration dependent manner,berberine (1 ~50 mg/L) significantly inhibited the HUVEC proliferation induced by ox-LDL,and reduced the expressions of proliferating cell nuclear antigen (PCNA),nuclear factor κB (NF-κB) and lectin-like oxidized low density lipoprotein receptor-1 (LOX-1).These effects were associated with decreased phosphorylation levels of PI3K/Akt,ERK1/2 and p38MAPK signaling pathways.Conclusion Berberine inhibits the proliferation of HUVEC induced by ox-LDL through the down-regulation of PCNA,NF-κB and LOX-1 expressions.PI3K/Akt,ERK1/2 and p38MAPK signaling pathways are involved in this process.关键词
