1 Anisomycin and UV radiation have been suggested to induce c-fos and c-jun transcription via JNK/SAPK-mediated phosphorylation of TCF (ternary complex factor), for c-fos induction [6-8], and c-Jun and/or ATF-2 for c-jun induction [9-11] [12,13].

2 By using the p38/RK inhibitor SB 203580 [20,21], we show that activation of p38/RK and/or its downstream effectors are essential for anisomycin- and UV-stimulated c-fos/c-jun induction and histone H3/HMG-14 phosphorylation, whereas JNK/SAPK activation and phosphorylation of c-Jun and ATF-2 are insufficient for these responses.
