Figure 6. The alternative NF-κB pathway suppresses ROS production through the regulation of RacGAP.
(A) Table summarizing the fold effect on RACGAP1 expression induced by transfection of the listed siRNAs in the microarray analysis. (B) NF-κB2, RelB and EZH2 regulate RACGAP1 expression in NHD fibroblasts. RNA was prepared from NHD fibroblasts treated with the indicated siRNAs and Q-PCR analysis of RACGAP1 expression was performed. (C) siRNA mediated knock-down of RACGAP1 induces ROS production. NHD fibroblasts were transfected with the siRNAs shown and analyzed for ROS production after 4 days. (D) ROS production induced by siRNA mediated knock down of NF-κB2 and RelB is dependent upon Rac1 and Cdc42. NHD fibroblasts were transfected with the siRNAs shown and analyzed for ROS production after 4 days.
