Figure 5. The increase in the expression of miR-146a and miR-146b-5p in human retinal pigment epithelial cells was dependent on the concentration of inflammatory cytokines. The microRNA (miRNA) expression was analyzed by real-time PCR after treating the cells with the indicated concentrations of interferon (IFN)-γ, tumor necrosis factor (TNF)-α, and interleukin (IL)-1β for 16 h. *p<0.002 when compared to control, n=4. The data from one of three similar experiments are shown here.
