IκBα protein expression decreases in response to 4 h of TNF-α or taxol treatment. (A) Immunoblot of IκBα from C2C12 cells treated with 5 ng/ml TNF-α or 20 µM taxol in the presence or absence of 355 µM CHX (100 µg/ml). (B) Quantitation of bands shows the loss of IκBα by 40% from treatment with either NF-κB inducer (P<0.05).
