GATA3 knockdown in Jurkat cells transfected with Tf-Mel-PEI polyplexes containing 25 pmol of different GATA3 siRNA sequences at N/P 10 as measured by qRT-PCR and normalized against ß-Act in expression. Control cells were left untreated (blank) or transfected with respective polyplexes containing scrambled siRNA as negative control (NC). (Data points indicate mean ± SD, n = 3; One-way ANOVA, *, p < 0.05; **, p < 0.01; ***, p < 0.005).
