摘要:
目的:探讨氧化修饰低密度脂蛋白(ox-LDL)对人单核细胞源巨噬细胞(HMDM)组织基质金属蛋白酶抑制物 (TIMPs)的基因和蛋白表达的影响。方法:分别应用RT-PCR和Westernblot检测TIMPs(TIMP-1和TIMP-2)基 因和蛋白表达。结果:ox-LDL可明显抑制HMDM TIMP-1mRNA及其蛋白的表达,但对TIMP-2mRNA及其蛋 白的表达无明显影响。结论:ox-LDL可抑制HMDM TIMP-1mRNA及其蛋白的表达,可能间接增强基质金属蛋 白酶(MMPs)活性。
Abstract:
AIM:To observe the effects of ox-LDL on the expressions of TIMPs (Tissue In hibitors of Metalloproteinase).METHODS:The gene and protein expressions of TIMPs(TIMP-1and TIMP-2)were respectively detected byRT-PCR and Western blot. RESULTS:ox-LDL can obviously decrease the expressions of TIMP-1 gene and its protein in human monocytes,but does not affect the expression of TIMP-2.CONCLUSION:Ox-LDL can decrease the expressions of TIMP-1 gene and its protein in human monocytes
