摘  要:目的 观察沉默信息调节因子1(SIRTl)和叉头盒转录因子M1(FOXMl)在病理性瘢痕中的表达及其相互关系,探讨它们在瘢痕形成中的作用及机制.方法 利用实时荧光定量聚合酶链反应(FQ-PCR)法、Western blot检测正常皮肤(10例)、成熟瘢痕(10例)、病理性瘢痕(10例)组织中SIRT1和FOXM1的mRNA、蛋白表达水平并进行统计学分析.结果 正常皮肤、成熟瘢痕、病理性瘢痕组织中SIRT1的mRNA及蛋白相对表达水平分别为1.0、1.187982±0.082916、2.402 178±0.178 598;0.498 614±0.056 342、0.534 159±0.044 509、0.976 829±0.145 736.FOXM1的mRNA及蛋白相对表达水平分别为1.0、1.196 429±0.086 786、2.447 249±0.128 875;0.469 935±0.089 373、0.552 653±0.078 293、0.915 367±0.114097.病理性瘢痕组织中SIRT1与FOXM1的mRNA相对表达水平均显著高于正常皮肤、成熟瘢痕(P<0.01);病理性瘢痕组织中SIRT1与FOXM1的蛋白相对表达水平均明显增高,与正常皮肤、成熟瘢痕对照组比较差异有统计学意义(P<0.05).结论 SIRT1和FOXM1在病理性瘢痕组织中表达增高,通过调节这两个因子的表达,可能促进瘢痕组织中细胞的增生,对病理性瘢痕的形成可能起重要作用.Objective To study the expression of sirtuin type 1 (SIRT1) and forkhead box M1 (FOXM1) gene in the pathological scars and to investigate its role and its probable mechanism in the pathogenesis of abnormal scar.Methods Real-time fluorescent quantitative polymerase chain reaction (FQ-PCR) and Western blotting was performed to detect the expression and distribution of mRNA and protein of SIRT1 and FOXM1 in normal skin (10 cases),normal scar (10 cases),and pathological scar (10cases),statistics was used to analyze the datas.Results The expression of SIRT1 mRNA and protein in the normal skin (10 cases),normal scar (10 cases),pathological scar (10 cases),were 1.0,1.187 982 ± 0.082 916,2.402 178 ± 0.178 598 ; 0.498 614 ± 0.056 342,0.534 159 ± 0.044 509,0.976 829 ±0.145 736.The expression of FOXM1 mRNA and protein in the normal skin (10 cases),normal scar (10 cases),pathological scar (10 cases),were 1.0,1.196 429 ±0.086 786,2.447 249 ±0.128 875; 0.469 935 ±0.089 373,0.552 653 ±0.078 293,0.915 367 ±0.114 097.The expression of SIRT1 and FOXM1 mRNA in pathologic scar were significantly higher than that in normal skin,normal scar (P <0.01) ; The expression of SIRT1 and FOXM1 protein in pathologic scar were all remarkably significant in comparison with normal skin and normal scar (P < 0.05).Conclusion The result indicated that the expression of SIRT1 and FOXM1 was increased in pathological scar.Therefore,SIRT1 and FOXM1 overexpression may play an important role in the proliferation of fibroblasts and in the pathogenesis of pathological scar.
