Figure 6. Effect of siRNA mediated AQP5 down-regulation (AQP5DR) on cell proliferation in CEPI17 cells. A: SRB assay shows that AQP5DR increased cell proliferation in CEPI17 cells (significant at 3 and 5 days p<0.05, 95% CI as determined by the paired T-Test, [n=3]). There was no significant difference in phosphorylated ERK 96 h post transfection in CEPI17 cells when compared to the controls as shown by western blot analysis (B).
