Figure 6. The NF-κB inhibitor counteracts the effect of PGF on the EMT in ARPE-19 cells under hypoxia. A: Representative protein blots of α-SMA, E-cadherin, ZO-1, p- p65, and IκB-α in the total protein and semiquantitative analyses of the protein expression levels. β-actin was used as the internal reference. B: Representative protein blots of p65 in the nuclear protein and semiquantitative analyses of the protein expression levels. Histone H3 was used as the nuclear internal reference. Data are the mean ± standard deviation (SD), n = 3, *p<0.05 versus the other four groups.
