Figure 2AB. Expression of PKC isoforms in ARPE19 cells. (A) Conventional PCR gel image showing expression of eight PKC isoforms-PKCα, PKCβI, PKCδ, PKCε, PKCη, PKCζ, PKCι and PKCμ in ARPE19 cells. (B) Real-time RT-PCR analysis of PKC isoforms in ARPE19 cells following POS, oxPOS treatments and untreated control. *, P < 0.05; **, P < 0.01, ***, P < 0.001 compared to the control untreated group. One-way ANOVA followed by Dunnett’s multiple comparison test. N = 3.
