Figure 4. 4HPR-induced expression of miR-9 in ARPE-19 cells is associated with increased expression of CEBPA and CEBPB. The cells were treated with 10 μM of 4HPR for 24 h, and the gene expression was analyzed using real time RT–PCR. A: 4HPR increased miR-9 expression. B: 4HPR increased CEBPA expression. C: 4HPR increased CEBPB expression. *p<0.05 compared to control, n=4.
