Abstract

Naturally occurring isothiocyanates are effective chemoprotective agents against chemical carcinogenesis in experimental animals. In the present study, we clarified the molecular mechanism underlying the relationship between benzyl isothiocyanate (BITC)-induced cell cycle arrest and apoptosis. The exposure of HL-60 cells to BITC resulted in the inhibition of the G_{2}/M progression that coincided with the apoptosis induction. We demonstrated that BITC significantly up-regulated expression of the G_{2}/M cell cycle arrest-regulating genes including p21, GADD45, and 14-3-3σ. Thus, these gathered data further supported that BITC has a potential to induce apoptosis selectively in the proliferating pre-cancerous cells through a cell cycle arrest-dependent mechanism.
