Figure 6. Time-dependent changes in the markers of senescence in human retinal pigment epithelial cells treated with FK866. Human retinal pigment epithelial cells (ARPE-19) were treated with 10μM FK866 for 24, 48 and 72 hr. and changes in the expression of various senescence markers was evaluated by qPCR and western blotting. Time-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).
