Objective:To investigate the effect oftumor necrosis factor (TNF)-α on the expression ofc-jun in the cultured human retinal pigment epithelial(RPE)cells.Methods:RPE cells were exposed to 40 ng/ml TNF-α for 0
10
20
40 and 40 minutes
respectively.Immunofluorescence staining and reverse transcription polymerase chain reaction(RT-PCR)were used to detect the levels of c-jun protein and mRNA in RPE cells.Results:Untreated RPE cells revealed faint or none green fluorescence of c-jun in the cytoplasm and some nuclei.With exposure to TNF-α
c-jun increased obviously with stronger green fluorescence.With treatment of TNF-α
c-jun mRNA increased gradually and enhanced to the peak at 40 min.Conclusion:TNF-α can up-regulate c-jun protein and mRNA in cultured human RPE cells and induce its nuclear transposition
