Disulfiram (DSF), an anti-alcoholism drug, has been reported as an inhibitor of
NF-?B. NF-?B is involved in epithelial-mesenchymal transition (EMT) and
self-renewal of breast cancer stem cells (CSCs). In this study, we treated MCF-7
and MDA-MB-231 breast cancer cells with TGF-? to induce EMT and cancer stem-like
features and studied whether DSF can reverse this process. We found that DSF
inhibited TGF-? induced EMT in breast cancer cells in a dose-dependent manner.
Also, DSF inhibited EMT-associated stem-like features, migration and invasion of
tumor cells as well as tumor growth in xenograft model. The activation of NF-?B
was linked with EMT and stem-like cells. We conclude that DSF can suppress NF-?B
activity and downregulate ERK/NF-?B/Snail pathway, leading to reverse EMT and
stem-like features. Our data suggest that DSF inhibits EMT and stem-like
properties in breast cancer cells associated with inhibition of the
ERK/NF-?B/Snail pathway.
