Abstract:
Objective To investigate the effects of all-trans-retinoic acid(ATRA) on proliferation of cultured human retinal pigment epithelium(RPE) cells and the probable mechanisms.Methods Cultured human RPE cells were treated with various concentrations(10-9,10-8,10-7,10-6 and 10-5 mol?L-1) of ATRA at different time points(6,12,24,48,72 and 96 h).Cell proliferation was evaluated by cell count and MTT colorimetric assay,and cell cycle analysis was performed by flow cytometry.Results The cell viability rates of ATRA treated group were decreased obviously,compared with control groups(P
