Cordycepin mediates the regulation of MKK7 by GADD45B via NF-κB suppression.

(A) Effect of GADD45B on MKK7 expression in cordycepin-treated TK-10 cells. (B) Effect of MKK7 on JNK expression in cordycepin-treated TK-10 cells. (C) Effect of TNF-α-induced NF-κB on c-FLIPL expression. (D) Effect of c-FLIPL on JNK expression in cordycepin-treated TK-10 cells. The data represent the mean ± SE from three independent experiments. **p < 0.01 and *** p < 0.001.
