Abstract

Ever since several targeted agents were introduced a decade ago, progress in new therapeutic strategies for colorectal cancer (CRC) has been much slower than that for other cancers. Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) is widely known to induce cellular apoptosis in numerous cancer cell types. However, many cancer cells are resistant to the effects of TRAIL, and thus, approaches are needed to overcome TRAIL resistance. We demonstrated that non-cytotoxic doses of diallyl disulfide (DADS) increased TRAIL-associated cell death in CRC cell lines. Additionally, synergistic effects between DADS and TRAIL were validated in vivo in nude mice. One process involved in these effects includes down-regulation of the anti-apoptotic protein Bcl-2, and the synergistic effect of DADS with TRAIL was attenuated in Bcl-2-over-expressing cells. Taken together, the results of this study give new insights into the role of DADS in TRAIL-related repression of CRC progression by inhibition of Bcl-2.
