摘要
目的探讨瑞舒伐他汀对氧化修饰低密度脂蛋白(OX-LDL)诱导的人单核-巨噬细胞组织因子(TF)表达影响及可能机制。方法据实验要求分空白对照组、OX-LDL组、多聚肌苷酸组、瑞舒伐他汀组。RT-PCR检测各组血凝素样氧化低密度脂蛋白受体-1(LOX-1)mRNA,TFmRNA表达,ELISA检测各组TF蛋白表达。结果OX-LDL组与空白对照组比较,LOX-1mRNA、TFmRNA表达增加[(3.25156±0.15772)VS(1±0);(2.522451±0.138967)VS(1±0)],其差异均有统计学意义(P〈0.01)。多聚肌苷酸组、瑞舒伐他汀组与OX-LDL组比较,LOX-1mRNA、TFmRNA表达减少[(2.95139±0.157253)VS(3.25156±0.15772)、(2.877343±0.156558)VS(3.25156±0.15772);(1.811956±0.169699)VS(2.522451±0.138967)、(1.687701.4-0.174647)vs(2.522451±0.138967)],其差异均有统计学意义(P〈0.05)。ox-LDL组与空白对照组比较,TF蛋白表达增加[(207.7233±1.154701)VS(184.8467±0.871799)],差异有统计学意义(P〈0.01)。多聚肌苷酸组、瑞舒伐他汀组与OX-LDL组比较,TF蛋白表达均减少[(197.8733±1.505003)vs(207.72334-1.154701)、(202.95674-2.722744)VS(207.7233±1.154701)],差异均有统计学意义(P〈0.05)。结论LOX-1可能介导OX-LDL诱导的人单核-巨噬细胞TF表达增加。瑞舒伐他汀可通过下调单核-巨噬细胞LOX.1mRNA的表达下调TFmRNA表达,从而下调TF蛋白表达。
Objective To investigate the effects and mechanism of rosuvastatin on the expression of tissue factor in cultured human monocyte-macrophages cells which was induced by oxidized low density lipo- protein(ox-LDL). Methods The human monocyte-macrophages cells were divided into four groups: con- trol group, ox-LDL group, Poly-inosine monophosphate (Poly I )group, rosuvastatin group. The expressionof LOX-lmRNA and TF mRNA was assayed by RT-PCR. The ELISA was performed to determine the protein concentration of TF. Results Compared with control group, the expression of LOX-1 mRNA and TF mR- NA was increased in the ox-LDL group [ ( 3.25156 ± 0. 15772 ) vs ( 1 ± 0 ) ; (2. 522451 ± 0.138967 ) vs ( 1 ±0) ], and it was in a concentration-dependent manner ( P 〈 0. 01 ). Compared with the expression ofLOX-1 mRNA in the Poly-inosine monophosphate group and rosuvastatin group, TF mRNA were decreased in the ox-LDL group[ (2. 95139 ±0. 157253) vs(3.25156 ±0. 15772) ; (2. 877343 ±0. 156558) vs(3. 25156 ± 0. 15772) ; ( 1. 811956 ± 0. 169699 ) vs (2. 522451 ± 0. 138967 ) ; ( 1. 687701 ± 0. 174647 ) vs (2. 522451 ± 0. 138967)], and if was in a concentration-dependent manner( P 〈 0. 05). Compared with control group,the expression of TF in the ox-LDL group was increased [ ( 207. 7233 ± 1. 154701 ) vs ( 184. 8467 ± 0. 871799) ], and it was in a concentration-dependent manner ( P 〈0. 01 ). Compared with the Poly-ino- sine monophosphate group and rosuvastatin group [ ( 197. 8733 ± 1. 505003) vs (207.7233 ± 1. 154701 ) ;(202. 9567 ±2. 722744)vs(207. 7233 ±1. 154701 )] , the expression of TF in the ox-LDL group were de- creased, and it was in a concentration-dependent manner ( P 〈 0. 05 ). Conclusions LOX-1 may be re- sponsible for the expression of TF in human monocyte-macrophages cells induced by ox-LDL. Rosuvastatin is able to down-regulate the expression of LOX-lmRNA in human monoeyte-maerophages cells through ox- L
