摘要：
AIM: To investigate the characteristics of Ets-1 and VEGF expression and distribution in the experimental diabetic rat retina. METHODS: Diabetes was induced by intraperitoneal injection of streptozotocin (STZ). At 4 weeks after STZ-injection, animals were sacrificed. Total proteins were isolated from retinas of experimental eyes and control eyes and assessed by Western blot analysis. Frozen cross sections of eyeballs with 14 mu m thickness were used to perform double immunofluorescence staining with anti-Ets-1 and anti-VEGF antibodies. RESULTS: Both Ets-1 and VEGF expression were up-regulated in the diabetic retina, the distribution of Ets-1 and VEGF was identical to each other, and the two proteins were almost localized in all retinal layers. CONCLUSION: Ets-1 may contribute to the pathologic progress of the diabetic retina induced by VEGF.
