SP600125 (1,9‐pyrazoloanthrone anthrapyrazolone) was reported to be a specific inhibitor of JNK.1, 14, 15, 16 Therefore, we next examined the survival and proliferation of laryngeal cancer cell AMC‐HN‐8 treated with irradiation, Tanshinone IIA, and SP600125 by clonogenic assay kit. The gene discussed is MAPK8; the disease is laryngeal carcinoma.
