title: Diallyl trisulfide induces Bcl-2 and caspase-3-dependent apoptosis via downregulation of Akt phosphorylation in human T24 bladder cancer cells.
abstract: It is well known that the garlic-derived organosulfur compounds (OSCs) are effective to inhibit a variety of human cancers such as prostate, breast, colon, skin, lung, and bladder cancers. Herein, the pro-apoptotic effects of diallyl trisulfide (DATS), one of garlic-derived OSCs, on T24 bladder cancer cells were investigated. The results demonstrated that DATS suppressed proliferation of T24 bladder cancer cells in a dose- and time-dependent manner which was associated with induced G2/M Phase cell cycle arrest and apoptosis. Mechanistically, DATS inhibits phosphatidylinositol 3'-kinase/Akt activation that, in turn, results in modulation of Bcl-2 family proteins, leading to enhanced apoptosis of T24 cells. These findings suggest that DATS may be an effective way for treating human bladder and other types of cancers.
