ABSTRACT
Objective To investigate the effect of pigment epithelium-derived factor (PEDF) on rat retinal Müller cells under high glucose conditions. Methods Müller cells cultured in 25 mmoL/L glncose were incubated with 100 ng/ml PEDF or 10 ng/ml interleukin-1β(IL-1β) for 24 h. The expression of IL-1β or PEDF in Müller cells was measured by indirect immunofluorescence, Western blot or realtime RT-PCR. The survival of Müller cells was detected by MTT assay. Results Under high glucose conditions, expression of IL-1β or PEDF was decreased after treated with 100 ng/ml PEDF or 10 ng/ml IL-1β for 24 hours by the methods of immunocytochemistry, Western blot or realtime PCR (P < 0.05). Activity of Müller cells was increased significantly by PEDF (0.48±0.09 vs 0.64±0.17, P<0.05). Conclusion In mimic diabetic conditions, PEDF decreases expression of IL-1β in rat retinal Müller cells and enhances the cell activity. To some degree, PEDF may block the process of inflammation in diabetic retinopathy.
