Iron chelator induced phosphorylated IκB-α in IHOK and HN12 cells on time dependent. Cells were treated with DFO (1.0 mM) or IL-1α (10 ng/ml) for the indicated time periods. Levels of IκB-α, p IκB-α were determined by Western blotting. The protein fraction was extracted, electrophoresed, transferred to membrane and blotted with respective antibodies. These data are representative of three independent experiments.
