Fig. (3) Phosphorylation level of the JNK protein in the response to thapsigargin (TG) diclofenac (DIC) and indomethacin (IND) in Huh7 cells. Western blot analysis of cell extracts obtained from Huh7 cells exposed to TG, DIC or to IND for the times indicated. Etopoxide was used as positive control for the JNK protein phosphorylation. The blots were probed with antibodies against the unphosphorylated (JNK) or phosphorylated (pJNK) JNK proteins.
