The aim of this study was to investigate the effect of garlic constituent diallyl trisulfide (DATS) on the cell death signaling pathway in a human breast cell line (MDA-MB-231). We observed that DATS (10–100 μM) treatment resulted in a dose- and time-dependent cytotoxicity. Treatment of MDA-MB-231 cells with a cytotoxicity inducing concentration of DATS (50–80 μM) resulted in an increase in the intracellular level of reactive oxygen species (ROS). Data from assay with MitoSOX™ Red reagent suggest that mitochondria are the main source of ROS generation during DATS treatment. DATS-induced oxidative stress was detected through glutaredoxin (GRX), a redox-sensing molecule, and subsequently GRX was dissociated from apoptosis signal-regulating kinase 1 (ASK1). Dissociation of GRX from ASK1 resulted in the activation of ASK1. ASK1 activated a downstream signal transduction JNK (C-Jun N-terminal kinase)-Bim pathway. SP600125, a JNK inhibitor, inhibited DATS-induced Bim phosphorylation and protected cells from DATS-induced cytotoxicity. Our results indicate that the cytotoxicity caused by DATS is mediated by the generation of ROS and subsequent activation of the ASK1-JNK-Bim signal transduction pathway in human breast carcinoma MDA-MB-231 cells.
