Abstract:
ObjectiveTo investigate the inhibitory effects of indomethacin(IN) on proliferation and DNA synthesis of cultured human fetal retinal pigment epithelium(hRPE) cells in vitro.MethodsPrimary culture and subculture of hRPE cells were established in vitro first.Cultured hRPE cells were treated by various concentrations 50,100,200,400,600 μ mol/L(final concentration)of IN for 24h.After 24h,the amount of DNA in RPE cells was determined by the absorbance at 280nm of Nucleic Acid δ Protein Analysis.Cells proliferation of RPE were measured with methyl thiazolyl tetrazolium(MTT) assay method by adding 100,200,400,600,800,1000μ mol/L(final concentration) of IN for 12h.ResultsAfter added various concentrations of IN,the DNA concentrations were ( 101.1712± 15.5124),( 88.6400± 13.5845),( 72.3651± 7.7969),( 59.9089± 10.7229),( 51.2236± 8.7757)μg/ml respectively,P values were 0.000,0.000,0.000,0.000,0.000(q test) as compared to that ( 213.7351± 83.1572)μg/ml in 0μg/L IN.The A values added 100,200,400,600,800,1000μmol/L of IN were ( 0.2367± 0.0546),( 0.1687± 0.0695),( 0.0819± 0.03461),( 0.0656± 0.01759),( 0.0554± 0.02865),( 0.0508± 0.02775)respectively,P values were 0 .158,0.000,0.000,0.000,0.000,0.000(q test) as compared to ( 0.2674± 0. 04302) of A value of 0ug/L IN.ConclusionThe data suggested that IN can inhibit DNA synthesis and proliferation of hRPE cells in vitro in a dose dependent manner.
