Figure 2From: Signaling role of iron in NF-kappa B activation in hepatic macrophagesI-kappa B kinase (IKK) and c-Jun NH2-terminal kinase (JNK) activity were determined on HM lysate collected at different time points after FeSO4 treatment. Note that IKK activity as assessed by phosphoylation of GST-I-kappa B-alpha (P-I-kappa B-alpha), is increased at 15 min after addition of iron while no activation of JNK is evident.Back to article page
