Figure 9. Effect of 4HPR on miRNA expression in ARPE-19 cells. The cells were treated with 10 μM 4HPR for 24 h, and the expression of miRNAs was analyzed using real-time RT–PCR. The relative expression levels for each miRNA in control and treated samples were estimated and used to calculate the fold change. *p<0.05 compared to control, n=4.
