Analysis of inhibition by JNK inhibitor SP600215 and/or ZVAD-FMK in MM cells (A) (B) MM.1S and U266 cells were cultured with indicated dose of Cerulenin for 24 hours, with or without JNK inhibitor SP600215 (10 M) and/or ZVAD-FMK (50 M) pretreatment for 1 hour. Cytotoxicity was determined by MTT assay. Values represent mean SD of quadruplicate cultures. Although ZVAD-FMK does not affect cytotoxicity by Cerulenin, JNK inhibitor significantly blocks Cerulenin-induced cytotoxicity (P<0.05). Supplementary Figure 3
