Fig. 2: CYLD phosphorylation is mediated by IKKs and can be reversed by IKK inhibitors.

a MT4 cells were treated with the indicated concentrations of MRT67307, TPCA, or both inhibitors for 24 h. DMSO was used as a negative control. Lysates were sequentially blotted with the indicated antibodies. b, c MT4 cells were treated as indicated with 5 µM (b) or 10 µM (c) of MRT67307, TPCA, or both inhibitors for 24–72 h. Cell viability was measured using the CellTiter-Glo assay for ATP levels. The viability of cells treated with DMSO was set at 100% for each time point. The results represent the mean ± S.D. from three independent experiments. *p < 0.05; **p < 0.01.
