To investigate the effect of dopamine on bone morphogenesis protein-2 (BMP-2) expression in retinal pigment epithelium (RPE) cells in vitro.
ARPE-19 cells as a human RPE cell line were cultured with dopamine for different times (2, 4, 6, 8, 12, 16 and 24h) or with different concentrations (0.1, 1, 2, 5, 10, 20, and 100 µg/mL) in vitro. BMP-2 mRNA expression level in ARPE-19 cells was analyzed with real-time polymerase chain reaction (PCR) analysis and BMP-2 protein level was measured with Western blot analysis. The active form of BMP-2 in the culture medium was measured with enzyme-linked immunosorbent assay (ELISA).
The expression level of BMP-2 increased significantly cultured with 20 µg/mL dopamine, at different time points (P<0.05). BMP-2 mRNA level peaked 2h and the protein level peaked at 6 and 8h after treatment. The concentrations of secreted BMP-2 elevated at 12h and peaked at 24h (P<0.05) in a time-dependent manner. Treated with 100 µg/mL dopamine for 6h, the expression levels of BMP-2 mRNA and protein in ARPE-19 cells were enhanced significantly compared to that in the untreated cells (P<0.05). And secreted BMP-2 protein in the cell culture supernatant was also increased (P<0.05).
Dopamine up-regulate BMP-2 expression in RPE cells, and this may be associated with its inhibitive effect on myopia development.
