Ted and analyzed by RT-PCR. (C) Time dependence of LTA-stimulated JNK phosphorylation. RBA-1 cells were pretreated with SP600125 for 1 h and then treated with 50 mg/ml LTA for the indicated time intervals. Phosphorylation of JNK and c-Jun was determined by western blot using an anti-phospho-JNK or phospho-c-Jun antibody. (D) Cells were transfected with an empty vector (pcDNA3, as a control) or dom
