摘要
目的 探讨视神经损伤后 ,信号转导子与转录激活子 (STAT3)蛋白在视网膜内表达和分布的变化。方法 免疫细胞化学、Westernblot及计算机图像分析技术。 结果 视神经切断术后 ,视网膜内STAT3表达水平上调 ,术后 1d达到高峰 ,并出现核转位增多现象。 5d后STAT3水平逐渐下降至正常。 结论 Janus激酶 信号转导子与转录激活子 (JAK STAT)信号转导途径可能通过STAT3蛋白的活化 。
Objective To study the expression and distribution of protein STAT3 in the retina after optic nerve transection. Methods Immunocytochemistry, Western blot and computer image analysis techniques were used. Results After optic nerve transection, STAT3 levels in the retina was highly up-regulated, the peak of which appeared at day 1 postaxotomy, then decreased gradually to the normal level 5 days later. More translocations of STAT3 to the nucleus were seen.Conclusion JAK-STAT signal transduction pathway was involved in the pathological processes in the retinal after transection of the optic nerve.
