Figure 3. FK866 treatments induce changes in the markers of senescence in human retinal pigment epithelial cells. Human retinal pigment epithelial cells (ARPE-19) were treated with different doses (0.01-10μM) of FK866 and changes in the expression of various senescence markers were evaluated by qPCR and western blotting. Dose-dependent changes in (A) p21^Waf/Cip1 mRNA, (B) p16^INK4a and p21^Waf/Cip1 protein and, (C-D) CTGF and ApoJ mRNA levels are shown. A representative western blot image from three replicates is shown. mRNA expression of genes were normalized to 18s expression. Data are presented as mean ± S.E.M for n=3 independent experiments. *p<0.05 compared to CON (Vehicle treated).
