Objective : To examine the effects of Beevenom on the cell proliferation of human breast carcinoma cell line MCF-7, we performed various experiments such as does-dependent effect of Beevenom on cell proliferation and viability, morphological changes, and alterations of apoptosis/cell cycle-regulatory gene products. Methods : Beevenom induced cell viability and proliferation of MCF-7 cells in a concentration-dependent manner. The anti-proliferative effect by Beevenom treatment in MCF-7 cells was associated with morphological changes such as membrance shrinking and cell rounding up. Results : Beevenom induced apoptotic cell death in a concentration-dependent manager, which was associated with degradation of ${\beta}$-catenin, an apoptotic target protein. Beevenom induced the Bax expressions, a pro-apoptotic gene, both in protein and mRNA levels, however, the levels of Bcl-$X_{S/L}$ expression, an anti-apoptotic gene, were down-regulated in Beevenom-treated cells. Western blot analysis and RT-PCT data revealed that the levels of cyclin of B1 protein and cyclin E mRNA were reduced by Beevenom treatment in MCF-7 cells, respectively, where as the expression of tumor suppressor p53 and cyclin dependent kinase inhibitor p21 mRNA were markedly increased in a concentration-dependent fashion. Conclusions : Taken together, these findings suggest that Beevenom induced inhibition of human breast cancer cell proliferation is associated with the induction of apoptotic cell death and Beevenom may have therapeutic potential in human breast cancer.
