摘 要:目的探讨真核翻译起始因子4E(eukaryotic translation initiation factor4E,eIF4E)在病理性瘢痕组织中的表达及其在病理性瘢痕形成中的作用及机制。方法(1)应用免疫组织化学SP法检测20例正常皮肤、20例成熟瘢痕、14例增生性瘢痕和25例瘢痕疙瘩组织中eIF4E蛋白的表达。(2)应用逆转录-聚合酶链式反应(RT—PCR)测定eIF4EmRNA在8例正常皮肤、8例成熟瘢痕、7例增生性瘢痕和8例瘢痕疙瘩组织中的半定量值。结果(1)病理性瘢痕组织中eIF4E蛋白表达增高,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)。(2)与正常对照组0.99±0.28比较,eIF4EmRNA在病理性瘢痕组织1.73±0.31中的表达显著增高,差异有统计学意义(P〈0.05)。结论eIF4E在病理性瘢痕组织中表达增高,eIF4E与病理性瘢痕的形成密切相关,可能对病理性瘢痕的形成起着重要作用。Objective To study the expression of eukaryotic translation initiation factor 4E (eIF4E) in the pathological scars and its probable role in the pathogenesis of pathological scars. Methods Immuno- histochemiscal technique was performed to detect the expression and distribution of eIF4E protein in hypertrophic scars (14 cases), keloids (25 cases), mature scars (20 cases) and normal skins (20 cases). Reverse transcription polymerase chain reaction (RT-PCR) was used to detect the eIF4E mRNA level in hypertrophic scars (7 cases), keloids (8 cases), mature scars (8 cases) and normal skins (8 cases). Results Thepositive rate of eIF4E protein expression was remarkably significant difference between normal scars and pathological scars (P〈0.05). The level of eIF4E mRNA in pathological scars 1.73±0.31 was higher than that in control group 0.99 ± 0.28. There was significant difference between two groups (P〈0.05). Conclusions The expression of eIF4E is increased in pathological scar. eIF4E expression is closely associated with the development of pathological scar. Therefore, eIF4E overexpression may play an important role in the proliferation of fibroblasts and in the pathogenesis of pathological scar.
