GA affects TF activities, and reduces RelB expression in MO-DCs. (a) HEK293T cells were transfected with TF responsive luciferase reporter vectors. After 5 h, cells were split, and aliquots were differentially treated in triplicates with GA, and/or the MO-DC maturation cocktail as indicated. One day later, luciferase activities were detected. Data show the means ± SEM of three experiments, normalized to the relative luciferase activity of untreated HEK293T cells, arbitrarily set to 1. Statistical significance: *versus unstimulated untreated, and ^#GA-treated at stimulated versus unstimulated state, and ^$GA-treated versus untreated at stimulated state (*^,$P < 0.05, **P < 0.01, ***^,###P < 0.001). (b) Groups of MO-DCs were generated as described (see legend of Figure 2). Derived protein (each 30 μg) was separated on SDS-PAGE, and western blots were performed. β-actin served as loading control. The graph is representative of two independent experiments.
